Part ofDivorce & Civil Partnership Dissolution Forms UK

Updated June 2026 · England & Wales
If you are petitioning to end a marriage or civil partnership on the grounds that it is void or voidable, Form D80G is the written statement you file to back up your nullity petition. It gives the court the factual picture behind your application and confirms, on oath, the grounds you are relying on. Getting this form right matters. The court reads it alongside your petition when deciding whether to grant a decree of nullity, so any gaps, contradictions or missing detail can slow things down or cause the application to be rejected. On this page I have set out what Form D80G is, what each section asks for, and how the annulment process tends to work in practice in England and Wales. If anything feels unclear as you go, a short phone conversation with an experienced legal adviser can help you think it through.

What this document is

Form D80G is one of a series of statement-in-support forms used in family proceedings. Each letter (A to G) corresponds to a different ground or type of petition, and the G version is specifically tied to nullity applications, where the petitioner is asking the court to declare that a marriage or civil partnership is either void from the start or voidable.

The form works hand in hand with the original nullity petition. Rather than repeating everything, it asks the petitioner to confirm the facts pleaded in the petition, flag any changes, and provide extra detail on sensitive matters such as lack of consent, mental disorder, pregnancy by another person at the time of the ceremony, certain medical conditions, or gender recognition issues.

It finishes with a statement of truth. The legal backbone for nullity is section 12 of the Matrimonial Causes Act 1973 for marriages and section 50 of the Civil Partnership Act 2004 for civil partnerships. The form is designed to draw out the information the court needs under those provisions before a decree of nullity can be granted.

How to use this document

  1. Read the petition again before you start. Before filling in Form D80G, go back to the nullity petition you filed (or the draft you are working from) and re-read Part 5 in particular, because several sections of D80G cross-refer to it. Having both documents in front of you avoids inconsistencies between the two, which is one of the most common reasons courts come back with queries.
  2. Confirm the petition and flag any amendments. The opening sections ask you to confirm you have read the petition and that its contents are true, and to set out any changes or additions you want to make. If something in the original petition is no longer accurate, or you have remembered further detail, write it out clearly here rather than leaving the court to guess. Precision in this section saves time later.
  3. Set out when and how you learned the relevant facts. Section 4 asks when and in what circumstances you became aware of the facts relied on in Part 5 of the petition. For voidable grounds in particular, timing matters because there are time limits for bringing proceedings. Be specific about dates and context, and avoid vague phrases like 'some time ago' where you can give a clearer answer.
  4. Answer the sensitive-grounds questions carefully. Sections 5 and 6 deal with matters such as knowledge at the time of the ceremony, consent, mental disorder, certain transmissible conditions, pregnancy by another person, and gender recognition under the Gender Recognition Act 2004. These questions are uncomfortable, but the court needs clear answers to decide whether the statutory grounds are made out. Keep your responses factual and to the point.
  5. Complete the interim certificate section, sign, and check service. Section 7 covers interim gender recognition certificates where relevant. At the end, sign and date the statement of truth, which confirms you believe the facts stated are true. Finally, confirm whether the respondent has returned an acknowledgement of service. A missing acknowledgement can hold up the next stage, so check this before filing.

Common questions

Q What is the difference between an annulment and a divorce?
A divorce ends a legally valid marriage or civil partnership. An annulment says the marriage or civil partnership was never legally valid in the first place (void) or can be set aside because of a defect such as lack of consent or non-consummation (voidable). The grounds, time limits and paperwork differ, which is why nullity has its own dedicated statement in support.
Q Who needs to complete Form D80G?
The petitioner, the person asking the court to annul the marriage or civil partnership, completes Form D80G. It is their written evidence in support of the nullity petition they have already filed. The respondent does not fill in D80G, although they may file their own documents, such as an acknowledgement of service or an answer to the petition, depending on their position.
Q Is there a time limit for applying for an annulment?
For voidable grounds under the Matrimonial Causes Act 1973 and the Civil Partnership Act 2004, there are time limits, often three years from the date of the marriage or civil partnership, with limited exceptions. Void marriages can generally be challenged at any time. Because the rules are nuanced, it is sensible to check your specific situation before filing.
Q Do I need a solicitor to complete Form D80G?
You are not required to use a solicitor. Many petitioners complete the form themselves, especially where the facts are straightforward. That said, nullity cases often involve sensitive or technical issues such as consent, capacity or gender recognition. If you are unsure how to describe your grounds, speaking to an experienced legal adviser first can help you approach the form with more confidence.
Q What happens after I file Form D80G?
Once the court has your petition, Form D80G and any supporting documents, a judge considers whether the grounds are made out. If satisfied, the court can grant a decree or order of nullity. There may be a conditional stage followed by a final stage, similar in structure to divorce. The exact steps depend on the grounds and whether the application is contested.
Q Is there a court fee to apply for an annulment?
Yes, a court fee applies to nullity applications in England and Wales. The amount can change, so check the current figure on gov.uk before filing. Fee remissions may be available if you are on certain benefits or have a low income. If you are filing on paper, send the fee with your forms, or pay online if you are using a digital service.
Q What if I make a mistake on Form D80G?
Small mistakes can sometimes be corrected by filing an amended statement, but errors or inconsistencies between the petition and D80G can delay things. If you spot an issue before filing, correct it and reprint the page. If you realise later, contact the court promptly. Taking care at the drafting stage is always cheaper and faster than fixing problems after filing.
