How to Respond to an Annulment Petition in California

California Annulment Library · Updated November 15, 2026

If you are served with a California annulment petition and summons, the usual deadline to respond is 30 days after service. Do not ignore the papers because you disagree with the accusation, because the marriage seemed valid, or because the other person says the matter will be resolved privately.

An annulment petition asks the court to determine that the marriage was legally invalid. That request can affect property and support rights as well as marital status. A response should address both the asserted ground and the relief you need.

What should you review first?

Keep the complete packet and record when and how you received it. Identify the court, case number, claimed ground, requested financial relief, any children listed, and all separate hearing dates. The response deadline is distinct from a hearing date.

Read the summons and its automatic restrictions. Existing support, custody, or protective orders remain important. The filing of a nullity petition does not itself excuse compliance or authorize moving assets.

If default has already been entered, obtain immediate advice about available relief. Simply filing a response late may not cure an existing default.

How do you respond on the merits?

FL-120, Response—Marriage/Domestic Partnership, is generally used to respond to the merits of a nullity petition. You can dispute the ground, contest the facts, or request appropriate alternative relief such as dissolution or legal separation.

If you question personal jurisdiction, service, venue, or the timeliness of the nullity proceeding, speak with counsel before making filings that could affect those objections. Certain motions may be appropriate within the response period. A general appearance can have legal consequences.

California Rules of Court, rule 5.63(b)(4), specifically addresses a motion to quash a nullity proceeding based on the statutory time limit. The correct procedure depends on the defense; not every objection belongs in the same form.

What defenses might matter?

• The alleged defect did not exist when the parties married.
• The asserted deception does not meet the legal standard for marital fraud.
• The petitioner knew the relevant facts before consenting.
• The evidence does not meet the applicable standard of proof.
• The case was commenced outside the statutory period.
• The petitioner is not a person authorized to bring that ground.
• Later free marital cohabitation defeats a ground under the applicable subdivision of section 2210.

A defense must fit the ground. For example, later free cohabitation may matter to fraud, force, or mental incapacity, but it does not automatically cure a marriage that was void because a prior spouse was still legally married to the party.

What evidence should you preserve?

Collect the marriage records, any prior judgments, premarital communications, and records of actual marital life. For fraud allegations, preserve complete exchanges about the disputed promise and the petitioner’s knowledge. For an immigration-related accusation, evidence of a genuine relationship may matter.

Include documents that do not favor your position. Your attorney needs to assess the complete record, including inconsistent statements, reconciliations, and the timing of discovery. Selective disclosure to counsel makes the case harder to prepare.

Do not delete messages, alter files, coach witnesses, or access accounts without authority. Keep original files and explain their source. Lawful evidence preservation is more useful than a large collection of questionable screenshots.

Can you contest annulment and request putative-spouse protection?

Those positions may be addressed in the alternative through appropriate pleadings. You may contend the marriage was valid while asking the court to protect your rights if it finds otherwise. The factual foundation for good-faith belief should be developed early.

Section 2251 provides a property remedy at the request of a declared putative spouse. Sections 2254 and 2255 address support and attorney-fee relief. Do not assume the judge will award those remedies without proper requests and evidence.

Should you agree to annulment to finish quickly?

Only after understanding the legal and financial consequences. Agreement cannot create a nonexistent ground, and a stipulated judgment may determine important facts between the parties. Review what the proposed judgment says about fraud, good faith, property, support, fees, and reserved issues.

An annulment may also have consequences beyond family court. Benefits, immigration, tax, pension, and estate questions may require separate professional review.

What is the realistic objective?

The objective is to secure the legally appropriate status determination and protect the claims the evidence supports. Sometimes that means defeating an unsupported annulment and proceeding with divorce. Sometimes it means resolving invalidity while protecting an innocent spouse’s financial interests.
