Formula and Logic

This calculator uses simplified reference rules based on common annulment statutes across major English-speaking jurisdictions. Eligibility is determined by matching your inputs to standard legal grounds for void or voidable marriages.

Case strength is calculated using a base score for each annulment ground, adjusted by marriage duration and input consistency. For example, bigamy and incest claims receive a 95-100% base strength, while fraud claims start at 60% and are reduced if the marriage has lasted over 2 years.

Filing deadlines are pulled from typical statutory limits for the selected jurisdiction. These are not exhaustive and may vary based on case-specific details.

Practical Notes

Annulment laws vary significantly by jurisdiction: some regions distinguish between void marriages (invalid from the start, no time limit to file) and voidable marriages (valid until annulled, strict filing deadlines).

Most jurisdictions require proof of the claimed ground, such as marriage certificates, medical records, witness testimony, or written communication. This tool does not assess evidence availability, only statutory eligibility.

Short-term marriages (under 2 years) have higher approval rates for most annulment grounds. Marriages lasting over 5 years are rarely annulled except in cases of bigamy or incest.

Always consult a qualified family law attorney in your jurisdiction before filing for annulment. This tool is not a substitute for professional legal advice.

Frequently Asked Questions

Is annulment the same as divorce?

No, annulment declares a marriage invalid from the start, while divorce ends a valid marriage. Annulment does not require a waiting period in most jurisdictions, but has stricter eligibility grounds than divorce.

Can I get an annulment after 10 years of marriage?

It is extremely rare. Most annulment grounds have filing deadlines between 1-4 years. Only void marriages (such as bigamy or incest) can typically be annulled after many years, as they were never legally valid.

Do I need a lawyer to file for annulment?

While not required in all jurisdictions, it is strongly recommended. Annulment filings have strict procedural requirements, and mistakes can lead to case dismissal. A lawyer can also help gather required evidence and meet deadlines.

Additional Guidance

Statutory limits and grounds for annulment change regularly. Always verify current laws with your local family court or a qualified attorney before taking action.

If your ground is not listed in the dropdown, select "Other" and consult an attorney immediately, as less common grounds have very specific evidentiary requirements.

Keep all records related to your marriage and claimed ground in a secure location, including messages, emails, medical records, and official documents. These will be required for filing even if this tool indicates eligibility.
