The Pontifical Council for Legislative Texts’ 308-article instruction of 25 January 2005, the day-to-day procedural manual followed by every diocesan and interdiocesan tribunal of the Latin Church in marriage-nullity cases. Selected articles, with Companion commentary for the petitioner and key sentences quoted from the official Vatican English text, each linked to the full article at vatican.va.
What this document is. An Instruction (an authoritative interpretive and applicative norm under CIC can. 34) issued by the Pontifical Council (now Dicastery) for Legislative Texts — the curial dicastery responsible for the authentic interpretation of universal Church law — that consolidates and systematizes the procedural law governing marriage-nullity cases. It does not create new law; it ordered, interpreted, and applied the existing canons for tribunal practitioners. Where it speaks, every Latin-rite tribunal listens.
Why it still matters after Mitis Iudex. Dignitas Connubii predates the 2015 reform. The articles that implemented the now-replaced cann. 1671–1691 must be read in light of the new canon texts — in particular, the articles requiring automatic second-instance confirmation no longer reflect operative law (the headline change of Mitis Iudex). But the great majority of the 308 articles — on the libellus, on witness testimony, on the role of the defender of the bond, on publication of the acts, on the sentence, on the right of the parties to inspect the record — remain the operative day-to-day procedural rules in 2026. The text of the Instruction published at vatican.va is still the 2005 text; it is read with the 2015 amendments overlaid by trained canonists.
Why a petitioner reads it. Because Dignitas Connubii is where the procedural rights of the parties — your rights as the petitioner, your former spouse’s rights as the respondent — are stated with the most operational specificity. The Code names the principle (the right to be heard, the right to know the grounds, the right to inspect the acts); Dignitas Connubii tells the tribunal exactly how to honor that principle, in writing, within named time limits.
Section I
Article 7 §1
“This Instruction is concerned only with the process for the declaration of the nullity of marriage...”

Article 6 §1
Paraphrased in the commentary below. Read Art. 6 in full: vatican.va.
The contentious-process spine. A marriage-nullity case runs through the ordinary contentious process (CIC cann. 1501–1655) unless the briefer process (after 2015) applies. The oral process — the simplified procedure available for some other contentious cases — is excluded. Your case is in writing, in named phases, with named officers (judge, defender of the bond, advocate, notary), and with named procedural rights (citation, hearing, publication of the acts, sentence).
Section II
Article 38 §1
“Every Diocesan Bishop is bound to appoint for his tribunal one Judicial Vicar...”
Read Art. 38 in full: vatican.va.
Who you are talking to. When you call the diocesan tribunal’s office, you are almost always talking, eventually, to the judicial vicar or his staff. The judicial vicar holds ordinary power of judging and forms one tribunal with the bishop (Art. 38 §§1–2); he presides over the tribunal, signs the procedural decrees, and routes the case. After Mitis Iudex, the judicial vicar is also the one who decides whether your case proceeds by the ordinary process or the briefer process (CIC can. 1676 §2).
What it means for you. Address correspondence to the judicial vicar by title. Phone-call messages reach his office, not the bishop’s personal calendar. The judicial vicar is, in practice, your interlocutor with the tribunal from intake through publication.
Article 56
“In causes of the nullity of marriage the presence of the defender of the bond is always required.” (§1)
Read Art. 56 in full: vatican.va.
The most misunderstood office. The defender of the bond is not your adversary. He is not the lawyer for your former spouse (your former spouse can have a separate advocate, if either of you choose). The defender is the canonical officer whose structural role is to argue, in good faith, that the marriage is valid — not because he believes it is, but because the law requires that someone in the process raise every reasonable counter-argument before a declaration of nullity can be granted. He keeps the tribunal honest. A nullity declared without the defender of the bond’s participation is canonically defective.
What it means for you. When you read a written observation from the defender of the bond raising arguments against the nullity of your marriage, do not read it as a personal attack. Read it as the law functioning correctly. Your task is to answer his arguments — through your advocate or in your own observations — not to be wounded by their existence.
Article 101
Paraphrased in the commentary below. Read Art. 101 in full: vatican.va.
What an advocate does. An advocate is a canonist trained in canon law and approved by the diocesan bishop to represent parties before the tribunal. The advocate drafts the libellus, frames the grounds, formulates questions for the witness interrogation, and writes the legal observations at publication. You are not required to have an advocate. But complex grounds — especially under can. 1095, 2° and 3° (lack of due discretion / incapacity), can. 1101 §2 (simulation), or where the respondent is participating and contesting — benefit materially from advocate counsel.
What it means for you. Ask the judicial vicar’s office for a list of approved advocates of the diocese. If you cannot afford one, you may ask for gratuitous legal assistance: if it is granted, the judicial vicar designates an advocate for you (Art. 306 §1, 1°; Art. 307 §1; CIC can. 1649 §1, 3°). If you cannot pay the tribunal’s costs at all, you have a right to an exemption from them; if you can pay part, you have a right to a reduction (Art. 305).
Section III
Article 116
“...must: 1° express the tribunal before which the cause is to be introduced; 2° describe the object of the cause...” (§1)
Items 3–5 (grounds and proofs; signature; the respondent’s domicile) are paraphrased in the commentary below. Read Art. 116 in full: vatican.va.
The five things every libellus must do. Name the tribunal. State the petition (the declaration of nullity is what is being sought, from the diocesan tribunal). State the grounds and the proofs (which canons are alleged and what evidence is being brought). Sign and date it. Locate the respondent. Most tribunals provide a libellus template that prompts the petitioner through these five elements.
What it means for you. The libellus is not a long autobiography. It is a precise canonical filing. The narrative of your marriage will come later, in the petitioner’s deposition. The libellus itself is short — usually two to four pages — and disciplined to these five items. If you are drafting a libellus without an advocate, follow the diocesan template; the temptation to write a memoir does not serve the case.
Article 119 Post-Mitis-Iudex reading
“...must either admit or reject the libellus by his decree as soon as possible (cf. can. 1505, §1).” (§1)
The four narrow grounds for rejection (CIC can. 1505 §2) are paraphrased in the commentary below. Read Art. 119 in full: vatican.va.
The narrow grounds for rejection. The libellus is accepted by default. A rejection requires either a competence defect, a standing defect, a formal defect under art. 116, or a clear-on-the-face foundationlessness. The judicial vicar cannot reject a libellus because he doubts the case will succeed. The merits are for the instruction; the libellus question is only whether the case is admissible.
Post-Mitis-Iudex overlay. The post-2015 acceptance norm (CIC can. 1676 §1) gives the defender of the bond and, unless the libellus was signed by both parties, the respondent a period of fifteen days to express their views on the petition. Article 119 (with CIC can. 1505) still governs admission and rejection. If the judge has not accepted or rejected the libellus within a month, you may insist that he act; if he takes no action within ten days of that request, the libellus is considered accepted (CIC can. 1506).
Section IV
Article 157
“Proofs of any kind which seem useful for understanding the cause and are licit can be brought forward.” (§1)
The burden-of-proof rule discussed below is the classical canonical maxim onus probandi incumbit ei qui asserit. Read Art. 157 in full: vatican.va.
The petitioner’s burden. You are the one alleging that the marriage is null. The presumption stands the other way (CIC can. 1060: marriage enjoys the favor of the law; in doubt, validity is to be upheld). Your burden is to prove the nullity — not to prove the perfect rightness of your former spouse’s every action, not to prove who is to blame for the marriage’s collapse, only the ground alleged — a defect of consent, a diriment impediment, or a defect of canonical form — as it stood at the moment of the wedding.
What it means for you. Your task is not to tell the worst story about your spouse. It is to give the tribunal — through your testimony, your witnesses, your documents — a true account of what happened, sufficient for the judge to reach moral certitude on the specific ground alleged. Many cases fail because the petitioner relitigates the marriage instead of evidencing the ground.
Article 179 Post-Mitis-Iudex overlay
“...an assertion about some fact, made...before a competent judge...against oneself, is a judicial confession.” (§1)
§2 defines a judicial confession in nullity cases: a party’s own statement of a fact about himself that goes against the validity of the marriage. The probative force of the parties’ declarations is set in Art. 180. Read Art. 179 in full: vatican.va.
What this article said in 2005. A confession of fact — an admission against your own interest — was treated as strong evidence. But for the public-good cases (which all nullity cases are, because marriage is a public good of the Church), neither a confession nor the broader declarations of the parties could reach the standard of full proof on their own; they required corroboration by other evidence.
What changed in 2015. Mitis Iudex rewrote CIC can. 1678 §1: the declarations of the parties “...can have the force of full proof, to be evaluated by the judge...unless other elements are present which weaken them.” The 2015 norm makes the parties’ own honest testimony, supported by credibility witnesses, capable of being full proof. Dignitas Connubii art. 180 §1, which required corroboration, is read in light of the post-2015 standard.
What it means for you. Your own testimony matters. The Companion’s journaling discipline — weekly entries through the multi-year process — is partly oriented at this: your contemporaneous account of how you remember the consent given, the courtship, the wedding day, the early months, the path to the breakdown, is canonical evidence.
Section V
Articles 195–196
“All persons may be witnesses, unless expressly excluded completely or partially by the law (can. 1549).” (Art. 195)
Read Arts. 195–196 in full: vatican.va.
Who counts as a witness. Anyone may testify unless the law excludes him. Minors under fourteen and persons of impaired mind are not admitted unless the judge decrees it expedient; the parties themselves, those acting for them in the case, the judge and his assistants, the advocate, and anyone else who assists or has assisted the parties in the same case cannot be witnesses; and priests cannot testify to anything learned in sacramental confession (Art. 196; can. 1550). What matters is what the witness saw, knew, or had reason to know — not whether the witness liked you or your former spouse.
What it means for you. When the tribunal asks for a witness list, name people who knew you and your former spouse during the courtship and the early marriage — people who can speak to the consent that was given. The temptation is to name witnesses to the marriage’s collapse; the more useful witnesses are usually those who saw the consent. Parents, siblings, a college roommate, a wedding-party member, the priest who married you if you have his contact — these are typical first-cut witnesses.
Article 203
Paraphrased in the commentary below. Read Art. 203 in full: vatican.va.
The psychological expert. Where the alleged ground touches lack of due discretion of judgment (can. 1095, 2°) or incapacity to assume the essential obligations of marriage (can. 1095, 3°), the tribunal will almost always appoint a psychological expert to evaluate one or both of the parties. The expert reviews the case file, may interview the parties, and submits a written report. The judge weighs the expert’s opinion against the rest of the evidence; the report is not dispositive on its own.
What it means for you. If the tribunal requests an expert evaluation, ask your advocate how the expert’s role works in your case.
Section VI
Article 229
“...the judge by the same decree must permit the parties and their advocates to examine the acts not yet known to them...” (§3)
The Code makes this a requirement under penalty of nullity (CIC can. 1598 §1). Read Art. 229 in full: vatican.va.
The most consequential procedural right. Before the tribunal proceeds to the conclusion of the case (the conclusio in causa), it must show the petitioner and the respondent — or their advocates — all the acts of the case: every witness deposition, every expert report. The right of inspection is so structural that violation of it is grounds for canonical nullity of the sentence. This is the moment, in canonical practice, at which both parties see what has been built.
What it means for you. You will receive a notification — usually a letter from the tribunal — that the acts are open for inspection. The tribunal sets a window for you to come read the file. If you have an advocate, the advocate may read it on your behalf and write the observations. If you do not, read the file carefully; if any fact is materially wrong, this is the moment to write your own observations correcting it.
The privacy exception. Art. 230 (and can. 1598 §1) lets the judge, to avoid very serious dangers, decree that an act not be shown to the parties, while the right of defense is kept intact.
Section VII
Article 247
“In order to declare the nullity of a marriage there is required in the mind of the judge moral certainty of its nullity.” (§1)
Read Art. 247 in full: vatican.va.
What moral certitude means. Not absolute certitude (which is unavailable about historical facts), not mere probability (which would not justify a declaration overturning the presumption of validity). Moral certitude is the firm assent the mind gives when, after weighing all the evidence honestly, the contrary opinion is not reasonable. The judge must be able to say that, on the whole of the proofs, any prudent positive doubt of error, in law or in fact, is excluded (Art. 247 §2), and that he is morally certain the marriage was null on this ground. If he cannot, the only canonical option is a negative sentence.
What it means for you if the sentence is negative. A negative sentence does not mean the tribunal called you a liar. It means the tribunal could not reach moral certitude on the ground alleged. The presumption of validity stood (can. 1060). You retain the right of appeal (can. 1628). A negative sentence imposes no penalty and does not change your access to the sacraments, which depends, as before, on your state of life. The crisis-protocol panel in the Companion exists for the day that letter arrives.
CIC can. 1611
“...set forth the reasons or motives in law and in fact on which the dispositive part of the sentence is based...”
Read can. 1611 at vatican.va. The Instruction repeats the rule at Art. 250 §1, 2°. Dignitas Connubii Art. 258 separately governs how the sentence is communicated to the parties: vatican.va.
What you receive when the sentence arrives. Not a one-line answer (“granted” or “denied”) but a reasoned document. The sentence states the canonical question, recites the relevant law (the canons alleged), summarizes the facts as the tribunal found them (drawn from your testimony, the respondent’s, the witnesses, the experts), and gives the canonical reasoning that ties the facts to the law. Read it carefully when it comes. Whether affirmative or negative, this document is the tribunal’s account of your marriage; it has historical and pastoral value beyond the dispositive line.
Section VIII
The 2015 reform replaced cann. 1671–1691 of the Code in their entirety. Dignitas Connubii was drafted in 2005 against the then-operative version of those canons. Three categories of Dignitas Connubii articles must be read carefully:
1. Articles unaffected by Mitis Iudex. The majority — covering the libellus, the conduct of testimony, witnesses, experts, publication of the acts, the right of inspection, the standard of moral certitude, the reasoning of the sentence, the right of defense — remain the operative procedural norm. Key sentences from them are quoted above.
2. Articles partially superseded. Some articles implement procedural details of canons that Mitis Iudex rewrote (especially around the joinder of issue, the role of the defender of the bond at the citation stage, and the routing decision between ordinary and briefer process). These articles are read in light of the new canon texts: where the article is consistent with the new canon, the article still applies; where the article reflects a now-superseded procedure (e.g., automatic second-instance review), the new canon governs.
3. Articles wholly superseded. The articles requiring automatic confirmation by a second instance, and certain articles that presumed the pre-2015 double-conforming-decision standard, no longer reflect operative law. CIC can. 1679 (post-Mitis Iudex): the affirmative sentence is executive after the lapse of the appeal term.
The text published at vatican.va is still the 2005 Instruction; trained canonists read Dignitas Connubii as a still-authoritative procedural manual with the 2015 amendments overlaid.
Source: Pontificium Consilium de Legum Textibus, Instructio servanda a tribunalibus dioecesanis et interdioecesanis in pertractandis causis nullitatis matrimonii, Dignitas Connubii, 25 January 2005. Published in Communicationes 37 (2005). The official English translation is published by the Holy See at vatican.va. The article numbers cited above (6, 7, 38, 56, 101, 116, 119, 157, 179, 195–196, 203, 229, 247, 258; with CIC can. 1611) are the canonical numbering of the Instruction.
What this Companion entry is and is not. The quotations above are key sentences taken from the official Holy See English translation of Dignitas Connubii (and, for the one CIC can. 1611 item, of the Code itself), each linked to the full article at vatican.va. The commentary that follows each quotation is the Companion’s pastoral framing for the petitioner. The commentary is not a substitute for an advocate (CIC can. 1481), for the judicial vicar of your diocese, or for the diocesan tribunal’s own canonical interpretation of the Instruction in particular cases. Where the Companion commentary and the tribunal’s instruction differ, the tribunal’s instruction governs your case. Where Dignitas Connubii and the post-Mitis Iudex Code differ, the Code governs.
What this article does. It draws the perimeter. Dignitas Connubii applies to nullity cases — the question of whether a valid marriage came into being — and to those cases only. Dissolutions super rato (non-consummated marriage) and in favorem fidei follow different procedures, treated separately in the Code and in their own dedicated norms.
What it means for you. If your case is a nullity case — the most common path — Dignitas Connubii applies. If your case is a super rato dispensation (a different canonical instrument, applicable when the marriage was never consummated), or a Pauline / Petrine privilege case, a different procedural framework applies. A 30-second conversation with the judicial vicar or your advocate will confirm which path your case is on. The Companion is designed for nullity cases; the super rato and privilege paths are not in scope.
