Canon 1526. §1 The onus of proof rests upon the person who makes an allegation.

§2 The following matters do not require proof:

1° matters which are presumed by the law itself;

2° facts alleged by one of the litigants and admitted by the other, unless their proof is nevertheless required either by law or by the judge.

§1. Onus probandi incumbit ei qui asserit.

§2. Non indigent probatione:

1° quae ab ipsa lege praesumuntur;

2° facta ab uno ex contendentibus asserta et ab altero admissa, nisi iure vel a iudice probatio nihilominus exigatur.

Canon 1527. §1 Any type of proof which seems useful for the investigation of the case and is lawful, may be admitted.

§2 If a party submits that proof, which has been rejected by the judge, should be admitted, the judge is to determine the matter with maximum expedition.

§1. Probationes cuiuslibet generis, quae ad causam cognoscendam utiles videantur et sint licitae, adduci possunt.

§2. Si pars instet ut probatio a iudice reiecta admittatur, ipse iudex rem expeditissime definiat.

Canon 1528. If a party or a witness refuses to testify before the judge, that person may lawfully be heard by another, even a lay person, appointed by the judge, or asked to make a declaration either before a public notary or in any other lawful manner.

Si pars vel testis se sistere ad respondendum coram iudice renuant, licet eos audire etiam per laicum a iudice designatum aut requirere eorum declarationem coram publico notario vel quovis alio legitimo modo.

Canon 1529. Unless there is a grave reason, the judge is not to proceed to collect the proofs before the joinder of the issue.

Iudex ad probationes colligendas ne procedat ante litis contestationem nisi ob gravem causam.

Canon 1530. The judge may always question the parties the more closely to elicit the truth. He must do so if requested by one of the parties, or in order to prove a fact which the public interest requires to be placed beyond doubt.

Iudex ad veritatem aptius eruendam partes interrogare semper potest, immo debet, ad instantiam partis vel ad probandum factum quod publice interest extra dubium poni.

Canon 1531. §1 A party who is lawfully questioned is obliged to respond and to tell the whole truth.

§2 If a party has refused to reply, it is for the judge to evaluate what, as far as the proof of the facts is concerned, can be deduced therefrom.

§1. Pars legitime interrogata respondere debet et veritatem integre fateri.

§2. Quod si respondere recusaverit, iudicis est aestimare quid ad factorum probationem exinde erui possit.

Canon 1532. Unless a grave reason suggests otherwise, in cases in which the public good is at stake the judge is to administer to the parties an oath that they will tell the truth, or at least that what they have said is the truth. In other cases, it is left to the prudent discretion of the judge to determine whether an oath is to be administered.

In casibus, in quibus bonum publicum in causa est, iudex partibus iusiurandum de veritate dicenda aut saltem de veritate dictorum deferat, nisi gravis causa aliud suadeat; in aliis casibus, potest pro sua prudentia.

Canon 1533. The parties, the promotor of justice and the defender of the bond may submit to the judge propositions upon which a party is to be questioned.

Partes, promotor iustitiae et defensor vinculi possunt iudici exhibere articulos, super quibus pars interrogetur.

Canon 1534. The provisions of can. 15482, n. 1, 1552 and 1558-1565 concerning witnesses are to be observed, with the appropriate qualifications, in the questioning of the parties.

Circa partium interrogationem cum proportione serventur, quae in can. 1548, §2, n. 1, 1552 et 1558-1565 de testibus statuuntur.

Canon 1535. A judicial confession is an assertion of fact against oneself, concerning a matter relevant to the trial, which is made by a party before a judge who is legally competent; this is so whether the assertion is made in writing or orally, whether spontaneously or in response to the judge’s questioning.

Assertio de aliquo facto, scripto vel ore, coram iudice competenti, ab aliqua parte circa ipsam iudicii materiam, sive sponte sive iudice interrogante, contra se peracta, est confessio iudicialis.

Canon 1536. §1 In a private matter and where the public good is not at stake, a judicial confession of one party relieves the other parties of the onus of proof.

§2 In cases which concern the public good, however, a judicial confession, and declarations by the parties which are not confessions, can have a probative value that is to be weighed by the judge in association with the other circumstances of the case, but the force of full proof cannot be attributed to them unless there are other elements which wholly corroborate them.

§1. Confessio iudicialis unius partis, si agatur de negotio aliquo privato et in causa non sit bonum publicum, ceteras relevat ab onere probandi.

§2. In causis autem quae respiciunt bonum publicum, confessio iudicialis et partium declarationes, quae non sint confessiones, vim probandi habere possunt, a iudice aestimandam una cum ceteris causae adiunctis, at vis plenae probationis ipsis tribui nequit, nisi alia accedant elementa quae eas omnino corroborent.

Canon 1537. It is for the judge, having considered all the circumstances, to evaluate the weight to be given to an extra-judicial confession which is introduced into the trial.

Quoad extraiudicialem confessionem in iudicium deductam, iudicis est, perpensis omnibus adiunctis, aestimare quanti ea sit facienda.

Canon 1538. A confession, or any other declaration of a party, is devoid of all force if clearly shown to be based on an error of fact or to have been extracted by force or grave fear.

Confessio vel alia quaevis partis declaratio qualibet vi caret, si constet eam ex errore facti esse prolatam, aut vi vel metu gravi extortam.

Canon 1539. In every type of trial documentary proof is admitted, whether the documents be public or private.

In quolibet iudicii genere admittitur probatio per documenta tum publica tum privata.

Canon 1540. §1 Public ecclesiastical documents are those which an official person draws up in the exercise of his or her function in the Church and in which the formalities required by law have been observed.

§2 Public civil documents are those which are legally regarded as such in accordance with the laws of each place.

§3 All other documents are private.

§1. Documenta publica ecclesiastica ea sunt, quae persona publica in exercitio sui muneris in Ecclesia confecit, servatis sollemnitatibus iure praescriptis.

§2. Documenta publica civilia ea sunt, quae secundum uniuscuiusque loci leges talia iure censentur.

§3. Cetera documenta sunt privata.

Canon 1541. Unless it is otherwise established by contrary and clear arguments, public documents constitute acceptable evidence of those matters which are directly and principally affirmed in them.

Nisi contrariis et evidentibus argumentis aliud evincatur, documenta publica fidem faciunt de omnibus quae directe et principaliter in iis affirmantur.

Canon 1542. A private document, whether acknowledged by a party or admitted by a judge, has the same probative force as an extra-judicial confession, against its author or the person who has signed it and against persons whose case rests on that of the author or signatory. Against others it has the same force as have declarations by the parties which are not confessions, in accordance with can. 1536 §2.

Documentum privatum, sive agnitum a parte sive recognitum a iudice, eandem probandi vim habet adversus auctorem vel subscriptorem et causam ab iis habentes, ac confessio extra iudicium facta; adversus extraneos eandem vim habet ac partium declarationes quae non sint confessiones, ad normam can. 1536, §2.

Canon 1543. If documents are shown to have been erased, amended, falsified or otherwise tampered with, it is for the judge to evaluate to what extent, if any, they are to be given credence.

Si abrasa, correcta, interpolata aliove vitio documenta infecta demonstrentur, iudicis est aestimare an et quanti huiusmodi documenta sint facienda.

Canon 1544. Documents do not have probative force at a trial unless they are submitted in original form or in authentic copy and are lodged in the office of the tribunal, so that they may be inspected by the judge and by the opposing party.

Documenta vim probandi in iudicio non habent, nisi originalia sint aut in exemplari authentico exhibita et penes tribunalis cancellariam deposita, ut a iudice et ab adversario examinari possint.

Canon 1545. The judge can direct that a document common to each of the parties is to be submitted in the process.

Iudex praecipere potest ut documentum utrique parti commune exhibeatur in processu.

Canon 1546. §1 No one is obliged to exhibit documents, even if they are common, which cannot be communicated without danger of the harm mentioned in can. 1548
§2, n. 2, or without the danger of violating a secret which is to be observed.

§2 If, however, at least an extract from a document can be transcribed and submitted in copy without the disadvantages mentioned, the judge can direct that it be produced in that form.

§1. Nemo exhibere tenetur documenta, etsi communia, quae communicari nequeunt sine periculo damni ad normam can. 1548, §2, n. 2 aut sine periculo violationis secreti servandi.

§2. Attamen si qua saltem documenti particula describi possit et in exemplari exhiberi sine memoratis incommodis, iudex decernere potest ut eadem producatur.

Canon 1547. Proof by means of witnesses is admitted in all cases, under the direction of the judge.

Probatio per testes in quibuslibet causis admittitur, sub iudicis moderatione.

Canon 1548. §1 Witnesses must tell the truth to a judge who lawfully questions them.

§2 Without prejudice to the provisions of can. 1550 §2, n. 2 the following are exempted from the obligation of replying to questions:

1° clerics, in those matters revealed to them by reason of their sacred ministry; civil officials, doctors, midwives, advocates, notaries and others who are bound by the secret of their office, even on the ground of having offered advice, in respect of matters subject to this secret;

2° those who fear that, as a result of giving evidence, a loss of reputation, dangerous harassment or some other grave evil will arise for themselves, their spouses, or those related to them by consanguinity or affinity.

§1. Testes iudici legitime interroganti veritatem fateri debent.

§2. Salvo praescripto can. 1550, §2, n. 2, ab obligatione respondendi eximuntur:

1° clerici, quod attinet ad ea quae ipsis manifestata sunt ratione sacri ministerii; civitatum magistratus, medici, obstetrices, advocati, notarii aliique qui ad secretum officii etiam ratione praestiti consilii tenentur, quod attinet ad negotia huic secreto obnoxia;

2° qui ex testificatione sua sibi aut coniugi aut proximis consanguineis vel affinibus infamiam, periculosas vexationes, aliave mala gravia obventura timent.

Canon 1549. Everyone can be a witness, unless expressly excluded, whether wholly or in part, by the law.

Omnes possunt esse testes, nisi expresse iure repellantur vel in totum vel ex parte.

Canon 1550. §1 Minors under the age of fourteen years and those who are of feeble mind are not admitted to give evidence. They can, however, be heard if the judge declares by a decree that it would be appropriate to do so.

§2 The following are deemed incapable of being witnesses:

1° the parties in the case or those who appear at the trial in the name of the parties; the judge and his assistant; the advocate and those others who in the same case assist or have assisted the parties;

2° priests, in respect of everything which has become known to them in sacramental confession, even if the penitent has asked that these things be made known.

Moreover, anything that may in any way have been heard by anyone on the occasion of confession, cannot be accepted even as an indication of the truth.

§1. Ne admittantur ad testimonium ferendum minores infra decimum quartum aetatis annum et mente debiles; audiri tamen poterunt ex decreto iudicis, quo id expedire declaretur.

§2. Incapaces habentur:

1° qui partes sunt in causa, aut partium nomine in iudicio consistunt, iudex eiusve assistentes, advocatus aliique qui partibus in eadem causa assistunt vel astiterunt;

2° sacerdotes, quod attinet ad ea omnia quae ipsis ex confessione sacramentali innotuerunt, etsi poenitens eorum manifestationem petierit; immo audita a quovis et quoquo modo occasione confessionis, ne ut indicium quidem veritatis recipi possunt.

Canon 1551. A party who has introduced a witness may forego the examination of that witness, but the opposing party may ask that the witness nevertheless be examined.

Pars, quae testem induxit, potest eius examini renuntiare; sed adversa pars postulare potest ut nihilominus testis examinetur.

Canon 1552. §1 When proof by means of witnesses is sought, the names and addresses of the witnesses are to be communicated to the tribunal.

§2 The propositions on which the interrogation of the witnesses is requested, are to be submitted within the time-limit determined by the judge; otherwise, the request is to be deemed abandoned.

§1. Cum probatio per testes postulatur, eorum nomina et domicilium tribunali indicentur.

§2. Exhibeantur, intra terminum a iudice praestitutum, articuli argumentorum super quibus petitur testium interrogatio; alioquin petitio censeatur deserta.

Canon 1553. It is for the judge to curb an excessive number of witnesses.

Iudicis est nimiam multitudinem testium refrenare.

Canon 1554. Before witnesses are examined, their names are to be communicated to the parties. If, in the prudent opinion of the judge, this cannot be done without great difficulty, it is to be done at least before the publication of the evidence.

Antequam testes examinentur, eorum nomina cum partibus communicentur; quod si id, prudenti iudicis existimatione, fieri sine gravi difficultate nequeat, saltem ante testimoniorum publicationem fiat.

Canon 1555. Without prejudice to the provisions of can. 1550, a party may request that a witness be excluded, provided a just reason for exclusion is established before the witness is examined.

Firmo praescripto can. 1550, pars petere potest ut testis excludatur, si iusta exclusionis causa demonstretur ante testis excussionem.

Canon 1556. The summons of a witness is effected by a decree of the judge lawfully notified to the witness.

Citatio testis fit decreto iudicis testi legitime notificato.

Canon 1557. A properly summoned witness is to appear, or to make known to the judge the reason for being absent.

Testis rite citatus pareat aut causam suae absentiae iudici notam faciat.

Canon 1558. §1 Witnesses are to be examined at the office of the tribunal unless the judge deems otherwise.

§2 Cardinals, Patriarchs, Bishops, and those who in their own civil law enjoy a similar favour, are to be heard at the place selected by themselves.

§3 Without prejudice to the provisions of cann. 1418 and 1469 §2, the judge is to decide where witnesses are to be heard for whom, by reason of distance, illness or other impediment, it is impossible or difficult to come to the office of the tribunal.

§1. Testes sunt examini subiciendi in ipsa tribunalis sede, nisi aliud iudici videatur.

§2. Cardinales, Patriarchae, Episcopi et ii qui, suae civitatis iure, simili favore gaudent, audiantur in loco ab ipsis selecto.

§3. Iudex decernat ubi audiendi sint ii, quibus propter distantiam, morbum aliudve impedimentum impossibile vel difficile sit tribunalis sedem adire, firmis praescriptis can. 1418 et 1469, §2.

Canon 1559. The parties cannot be present at the examination of the witnesses unless, especially when there is question of a private interest, the judge has determined that
they are to be admitted. Their advocates or procurators, however, may attend, unless by reason of the circumstances of matter and persons, the judge has determined that the proceedings are to be in secret.

Examini testium partes assistere nequeunt, nisi iudex, praesertim cum res est de bono privato, eas admittendas censuerit. Assistere tamen possunt earum advocati vel procuratores, nisi iudex propter rerum et personarum adiuncta censuerit secreto esse procedendum.

Canon 1560. §1 The witnesses are to be examined individually and separately.

§2 If in a grave matter the witnesses disagree either among themselves or with one of the parties, the judge may arrange for those who differ to meet or to confront one another, but must, in so far as possible, eliminate discord and scandal.

§1. Testes seorsim singuli examinandi sunt.

§2. Si testes inter se aut cum parte in re gravi dissentiant, iudex discrepantes inter se conferre seu comparare potest, remotis, quantum fieri poterit, dissidiis et scandalo.

Canon 1561. The examination of a witness is conducted by the judge, or by his delegate or an auditor, who is to be attended by a notary. Accordingly, unless particular law provides otherwise, if the parties or the promotor of justice or the defender of the bond or the advocates who are present at the hearing have additional questions to put to the witness, they are to propose these not to the witness, but to the judge, or to the one who is taking the judge’s place, so that he or she may put them.

Examen testis fit a iudice, vel ab eius delegato aut auditore, cui assistat oportet notarius; quapropter partes, vel promotor iustitiae, vel defensor vinculi, vel advocati qui examini intersint, si alias interrogationes testi faciendas habeant, has non testi, sed iudici vel eius locum tenenti proponant, ut eas ipse deferat, nisi aliter lex particularis caveat.

Canon 1562. §1 The judge is to remind the witness of the grave obligation to tell the whole truth and nothing but the truth.

§2 The judge is to administer an oath to the witness in accordance with can. 1532. If, however, a witness refuses to take an oath, he or she is to be heard unsworn.

§1. Iudex testi in mentem revocet gravem obligationem dicendi totam et solam veritatem.

§2. Iudex testi deferat iuramentum iuxta can. 1532; quod si testis renuat illud emittere, iniuratus audiatur.

Canon 1563. The judge is first of all to establish the identity of the witness. The relationship which the witness has with the parties is to be probed, and when specific questions concerning the case are asked of the witness enquiry is to be made into the sources of his or her knowledge and the precise time the witness came to know the matters which are asserted.

Iudex imprimis testis identitatem comprobet; exquirat quaenam sit ipsi cum partibus necessitudo et, cum ipsi interrogationes specificas circa causam defert, sciscitetur quoque fontes eius scientiae et quo definito tempore ea, quae asserit, cognoverit.

Canon 1564. The questions are to be brief, and appropriate to the understanding of the person being examined. They are not to encompass a number of matters at the same time, nor be captious or deceptive. They are not to be leading questions, nor give any form of offence. They are to be relevant to the case in question.

Interrogationes breves sunto, interrogandi captui accommodatae, non plura simul complectentes, non captiosae, non subdolae, non suggerentes responsionem, remotae a cuiusvis offensione et pertinentes ad causam quae agitur.

Canon 1565. §1 The questions are not to be made known in advance to the witnesses.

§2 If, however, the matters about which evidence is to be given are so remote in memory that they cannot be affirmed with certainty unless they are recalled beforehand, the judge may, if he thinks this can safely be done, advise the witness in advance about certain aspects of the matter.

§1. Interrogationes non sunt cum testibus antea communicandae.

§2. Attamen si ea quae testificanda sunt ita a memoria sint remota, ut nisi prius recolantur certo affirmari nequeant, poterit iudex nonnulla testem praemonere, si id sine periculo fieri posse censeat.

Canon 1566. The witnesses are to give evidence orally. They are not to read from a script, except where there is a question of calculations or accounts; in this case, they may consult notes which they have brought with them.

Testes ore testimonium dicant, et scriptum ne legant, nisi de calculo et rationibus agatur; hoc enim in casu, adnotationes, quas secum attulerint, consulere poterunt.

Canon 1567. §1 The replies are to be written down at once by the notary. The record must show the very words of the evidence given, at least in what concerns those things which bear directly on the matter of the trial.

§2 The use of a tape-recorder is allowed, provided the replies are subsequently committed to writing and, if possible, signed by the deponents.

§1. Responsio statim redigenda est scripto a notario et referre debet ipsa editi testimonii verba, saltem quod attinet ad ea quae iudicii materiam directe attingunt.

§2. Admitti potest usus machinae magnetophonicae, dummodo dein responsiones scripto consignentur et subscribantur, si fieri potest, a deponentibus.

Canon 1568. The notary is to mention in the acts whether the oath was taken or excused or refused; who were present, parties and others; the questions added ex officio; and in general, everything worthy of record which may have occurred while the witnesses were being examined.

Notarius in actis mentionem faciat de praestito, remisso aut recusato iureiurando, de partium aliorumque praesentia, de interrogationibus ex officio additis et generatim de omnibus memoria dignis quae forte acciderint, cum testes excutiebantur.

Canon 1569. §1 At the conclusion of the examination, the record of the evidence, either as written down by the notary or as played back from the tape-recording, must be communicated to the witness, who is to be given the opportunity of adding to, omitting from, correcting or varying it.

§2 Finally, the witness, the judge and the notary must sign the record.

§1. In fine examinis, testi legi debent quae notarius de eius depositione scripto redegit, vel ipsi audita facere quae ope magnetophonii de eius depositione incisa sunt, data eidem testi facultate addendi, supprimendi, corrigendi, variandi.

§2. Denique actui subscribere debent testis, iudex et notarius.

Canon 1570. Before the acts or the testimony are published, witnesses, even though already examined, may be called for re-examination, either at the request of a party or ex officio. This may be done if the judge considers it either necessary or useful, provided there is no danger whatever of collusion or of inducement.

Testes, quamvis iam excussi, poterunt parte postulante aut ex officio, antequam acta seu testificationes publici iuris fiant, denuo ad examen vocari, si iudex id necessarium vel utile ducat, dummodo collusionis vel corruptelae quodvis absit periculum.

Canon 1571. Witnesses must be refunded both the expenses they incurred and the losses they sustained by reason of their giving evidence, in accordance with the equitable assessment of the judge.

Testibus, iuxta aequam iudicis taxationem, refundi debent tum expensae, quas fecerint, tum lucrum, quod amiserint, testificationis reddendae causa.

Canon 1572. In weighing evidence the judge may, if it is necessary, seek testimonial letters, and is to take into account:

1° the condition and uprightness of the witness

2° whether the knowledge was acquired at first hand, particularly ifit was something seen or heard personally, or whether it was opinion, rumour or hearsay;

3° whether the witness is constant and consistent, or varies, is uncertain or vacillating;

4° whether there is corroboration of the testimony, and whether it is confirmed or not by other items of evidence.

In aestimandis testimoniis iudex, requisitis, si opus sit, testimonialibus litteris, consideret:

1° quae condicio sit personae, quaeve honestas;

2° utrum de scientia propria, praesertim de visu et auditu proprio testificetur, an de sua opinione, de fama, aut de auditu ab aliis;

3° utrum testis constans sit et firmiter sibi cohaereat, an varius, incertus vel vacillans;

4° utrum testimonii contestes habeat, aliisve probationis elementis confirmetur necne.

Canon 1573. The deposition of one witness cannot amount to full proof, unless the witness is a qualified one who gives evidence on matters carried out in an official capacity, or unless the circumstances of persons and things persuade otherwise.

Unius testis depositio plenam fidem facere non potest, nisi agatur de teste qualificato qui deponat de rebus ex officio gestis, aut rerum et personarum adiuncta aliud suadeant.

Canon 1574. The services of experts are to be used whenever, by a provision of the law or of the judge, their study and opinion, based upon their art or science, are required to establish some fact or to ascertain the true nature of some matter.

Peritorum opera utendum est quoties ex iuris vel iudicis praescripto eorum examen et votum, praeceptis artis vel scientiae innixum, requiruntur ad factum aliquod comprobandum vel ad veram alicuius rei naturam dignoscendam.

Canon 1575. It is for the judge, after hearing the opinions or suggestions of the parties, to appoint the experts or, if such is the case, to accept reports already made by other experts.

Iudicis est peritos nominare, auditis vel proponentibus partibus, aut, si casus ferat, relationes ab aliis peritis iam factas assumere.

Canon 1576. Experts can be excluded or objected to for the same reasons as witnesses.

Easdem ob causas quibus testis, etiam periti excluduntur aut recusari possunt.

Canon 1577. §1 The judge in his decree must define the specific terms of reference to be considered in the expert’s task, taking into account whatever may have been gathered from the litigants.

§2 The expert is to be given the acts of the case, and any documents and other material needed for the proper and faithful discharge of his or her duty.

§3 The judge, after discussion with the expert, is to determine a time for the completion of the examination and the submission of the report.

§1. Iudex, attentis iis quae a litigantibus forte deducantur, singula capita decreto suo definiat circa quae periti opera versari debeat.

§2. Perito remittenda sunt acta causae aliaque documenta et subsidia quibus egere potest ad suum munus rite et fideliter exsequendum.

§3. Iudex, ipso perito audito, tempus praefiniat intra quod examen perficiendum est et relatio proferenda.

Canon 1578. §1 Each expert is to complete a report distinct from that of the others, unless the judge orders that one report be drawn up and signed by all of them. In this case, differences of opinion, if there are such, are to be faithfully noted.

§2 Experts must clearly indicate the documents or other appropriate means by which they have verified the identity of persons, places or things. They are also to state the manner and method followed in fulfilling the task assigned to them, and the principal arguments upon which their conclusions are based.

§3 If necessary, the expert may be summoned by the judge to supply further explanations.

§1. Periti suam quisque relationem a ceteris distinctam conficiant, nisi iudex unam a singulis subscribendam fieri iubeat: quod si fiat, sententiarum discrimina, si qua fuerint, diligenter adnotentur.

§2. Periti debent indicare perspicue quibus documentis vel aliis idoneis modis certiores facti sint de personarum vel rerum vel locorum identitate, qua via et ratione processerint in explendo munere sibi demandato et quibus potissimum argumentis suae conclusiones nitantur.

§3. Peritus accersiri potest a iudice ut explicationes, quae ulterius necessariae videantur, suppeditet.

Canon 1579. §1 The judge is to weigh carefully not only the expert’s conclusions, even when they agree, but also all the other circumstances of the case.

§2 When he is giving the reasons for his decision, the judge must state on what grounds he accepts or rejects the conclusions of the experts.

§1. Iudex non peritorum tantum conclusiones, etsi concordes, sed cetera quoque causae adiuncta attente perpendat.

§2. Cum reddit rationes decidendi, exprimere debet quibus motus argumentis peritorum conclusiones aut admiserit aut reiecerit.

Canon 1580. Experts are to be paid their expenses and honorariums. These are to be determined by the judge in a proper and equitable manner, with due observance of particular law.

Peritis solvenda sunt expensae et honoraria a iudice ex bono et aequo determinanda, servato iure particulari.

Canon 1581. §1 Parties can designate their own experts, to be approved by the judge.

§2 If the judge admits them, these experts can inspect the acts of the case, in so far as required for the discharge of their duty, and can be present when the appointed experts fulfil their role. They can always submit their reports.

§1. Partes possunt peritos privatos, a iudice probandos, designare.

§2. Hi, si iudex admittat, possunt acta causae, quatenus opus sit, inspicere, peritiae exsecutioni interesse; semper autem possunt suam relationem exhibere.

Canon 1582. If, in order to decide the case, the judge considers it opportune to visit some place, or inspect some thing, he is to set this out in a decree. After he has heard the parties, the decree is to give a brief description of what is to be made available for this access.

Si ad definitionem causae iudex opportunum duxerit ad aliquem locum accedere vel aliquam rem inspicere, decreto id praestituat, quo ea quae in accessu praestanda sint, auditis partibus, summatim describat.

Canon 1583. After the inspection has been carried out, a document concerning it is to be drawn up.

Peractae recognitionis instrumentum conficiatur.

Canon 1584. A presumption is a probable conjecture about something which is uncertain. Presumptions of law are those stated in the law; human presumptions are those made by a judge.

Praesumptio est rei incertae probabilis coniectura; eaque alia est iuris, quae ab ipsa lege statuitur; alia hominis, quae a iudice conicitur.

Canon 1585. A person with a presumption of law in his or her favour is freed from the onus of proof, which then falls on the other party.

Qui habet pro se iuris praesumptionem, liberatur ab onere probandi, quod recidit in partem adversam.

Canon 1586. The judge is not to make presumptions which are not stated in the law, other than on the basis of a certain and determinate fact directly connected to the matter in dispute.

Praesumptiones, quae non statuuntur a iure, iudex ne coniciat, nisi ex facto certo et determinato, quod cum eo, de quo controversia est, directe cohaereat.
