What documentation does a diocese require to petition for freedom to marry after divorce and death of a former spouse?

1. What the Church is deciding — not a civil change

A diocesan tribunal issues a declaration of nullity (an ecclesiastical finding that a marriage lacked essential elements at consent), not a civil divorce or any alteration of civil records; a declaration frees a person to marry in the Church only if no other impediments remain ^{[5] [3]}. Church tribunals examine whether something essential was missing at the moment of the wedding — the inquiry is about the nature of consent, not the civil ending of a marriage ^[5].

2. Core documents you will almost always need

Most dioceses list a core packet: the written petition (often submitted through your parish), a certified copy of the civil marriage record and the civil judgment of divorce (or death certificate / obituary if spouse died), and recent sacramental records for Catholics (recent baptismal certificates) — diocesan sites and FAQs repeat these requirements ^{[1] [2] [3]}.

3. What tribunals additionally request: testimony, witnesses, and questionnaires

Beyond documentary proof, the petitioner completes a detailed questionnaire and supplies witness names and affidavits; tribunals will want multiple witnesses (some dioceses ask for 6–10 witnesses) and may send auditors to gather further evidence if testimony is weak ^{[2] [6]}. The burden of proof rests with the petitioner to establish nullity by moral certitude ^[7].

4. Recent procedural reforms and bishop-level discretion

Papal reforms in the past decade aimed to streamline access, expand the bishop’s role, remove some automatic appeal steps, and minimize costs — and dioceses have implemented a variety of processes (ordinary judicial, shorter/administrative, documentary) with strict criteria for abbreviated tracks (e.g., both spouses petitioning or respondent consenting, marriage duration limits) ^{[8] [9] [4]}. Expect local variation: what one diocese treats as documentary-evidence-able may require fuller investigation elsewhere ^[4].

5. Special notes when a former spouse has died

If a former spouse has died, civil death documentation (death certificate, obituary, or testimony) is typically requested to show civil freedom to remarry; canonically, a widow or widower is considered free to marry after a spouse’s death, but prior canonical impediments or defects (for example, lack of canonical form in an earlier marriage) still require tribunal review ^{[10] [11]}. Available sources do not mention a single universal checklist for post‑death situations; diocesan offices list death certificates among the usual proofs ^{[10] [1]}.

6. Practical preparation — timing, fees, and pastoral help

Diocesan pages advise working through your parish priest or advocate (the parish usually forwards the papers), gathering updated baptismal certificates (commonly dated within 3–6 months) and civil records well ahead of a wedding date; some dioceses emphasize minimum lead times for other marriage paperwork and that no one is refused for inability to pay, although costs and timing vary by tribunal ^{[2] [12] [13]}.

7. Where disputes or uncertainty arise

Expect delays when witnesses are slow, documents are missing, or the case needs supplemental investigation — tribunals sometimes assign auditors or request additional sworn affidavits; if a decision is affirmative, appeals windows and diocesan procedures determine finality ^{[2] [14]}. Different dioceses treat special cases (mixed marriages, previous non‑Catholic unions, lack of canonical form) with specific petition forms and dispensations ^{[15] [16] [17]}.

Limitations and how to proceed

This summary synthesizes diocesan FAQs and tribunal pages; local practice varies and detailed prerequisites depend on the diocese where you will petition. For definitive requirements, contact your parish priest or the tribunal office of the diocese where you belong — diocesan webpages cited here lay out typical document lists and process options ^{[1] [3] [2]}.
