Annulment in Maine: Grounds, Filing, and Consequences

An annulment in Maine is a court order declaring that a marriage was never legally valid, available only when something was fundamentally wrong with the union from the day it was formed. The grounds are narrow, the person asking carries the burden of proof, and the result is different from a divorce: the court treats the marriage as if it never existed rather than ending a recognized one.

Grounds That Qualify

Maine law splits invalid marriages into two groups. Some are automatically void under Title 19-A, Section 701, meaning they have no legal force from the moment of the ceremony. A court decree isn’t technically required to end them, but most people get one anyway to clean up their legal status for future marriages, property transactions, and government benefits.

The void categories are:

Bigamy — either spouse was still legally married to someone else at the time of the ceremony.¹
Close blood relationships — parents and children, siblings, grandparents and grandchildren, aunts or uncles with nieces or nephews, and first cousins without a physician’s certificate of genetic counseling. Maine does permit first-cousin marriages, but only with that documentation.¹
Failure to document prior marriages — either party didn’t submit proof that a previous marriage ended, or lied about how many times they had been married before.¹
Evading Maine law by marrying elsewhere — Maine residents who travel to another state specifically to get around these prohibitions and then return home will find their marriage treated as void here.¹

Section 701 also prohibits a person under guardianship from marrying without the guardian’s approval. Under a limited guardianship, that restriction only applies if the court specifically gave the guardian authority over marriage decisions.¹

For marriages that aren’t automatically void but are still legally defective, Section 752 lets either party file a complaint for annulment “when the validity of a marriage is doubted.” The court then examines the evidence and either annuls or affirms the marriage.² The Maine Judicial Branch describes the available grounds as “certain limited reasons” and points to bigamy and consanguinity as primary examples.³ In practice, the court looks at whether the marriage violated any provision of Maine’s marriage laws at the time it was contracted.

This is not a tool for ending a marriage you’ve come to regret. The defect has to go back to the wedding itself.

A note on age: effective June 2020, no one under 18 can obtain a marriage license in Maine.⁴ Marriages performed before that change involving an underage party who lacked the then-required parental or judicial consent may still be subject to annulment.

Section 752 also carries a good-faith clause for bigamy cases. If the second spouse genuinely believed the first spouse was dead, that the prior marriage was void, or that a divorce had already been finalized, the court must note that good faith in the annulment decree.² That notation can matter later for property rights and benefit eligibility.

Filing the Complaint

You file in the District Court in the county where you or your spouse lives. The Maine Judicial Branch does not publish an annulment-specific complaint form; the complaint follows the same general format as other family matters filings but must clearly explain the factual basis for why the marriage was legally invalid. Be specific. If the ground is bigamy, identify the prior marriage. If it’s consanguinity, state the family relationship. Vague allegations won’t move the case forward.

The starting paperwork includes a summary sheet (FM-002) and a Social Security Number Confidential Disclosure Form (CV-CR-FM-PC-200), which keeps sensitive identification data out of the public file.⁵

Filing fees for domestic relations cases in Maine District Court run about $120. If you can’t afford it, use the Application to Proceed Without Payment of Fees (form CV-067), which requires a financial affidavit of your income and expenses.⁶

Serving Your Spouse

After the clerk accepts your filing, you must officially notify your spouse under Rule 4 of the Maine Rules of Civil Procedure. There are two standard options:⁷

Mail service: send the summons and complaint by first-class mail with two copies of a notice and acknowledgment form and a prepaid return envelope. The recipient signs and returns the acknowledgment to create proof of service.
Personal delivery: a sheriff, deputy sheriff within their county, or another person authorized by the court hand-delivers the documents to your spouse.

The annulment decree cannot affect your spouse’s rights unless they were actually notified of the case or responded to the complaint.² Skipping or botching service is the fastest way to lose the case before a judge ever looks at it.

The Hearing and Decree

Because you are asking the court to declare a marriage never existed, you carry the burden of proof. That typically means your own testimony plus supporting documents: prior marriage certificates, vital records showing a family relationship, or evidence that required documentation was never filed.

If the judge finds the legal requirements are met, they sign a final decree of annulment, and both parties are returned to single status. Section 752 also permits the trial court to issue a final judgment during the appeal period when it finds no just cause for delay and the judgment won’t prejudice either party while an appeal is pending.²

Uncontested cases where both spouses agree can wrap up within a few weeks to a couple of months, depending on caseload. Contested cases take significantly longer.

What the Decree Can and Can’t Do

The annulment order can resolve parental rights and responsibilities for any minor children of the marriage, using the same standards that apply in divorce under Chapter 55 of Title 19-A.² The Maine Judicial Branch confirms that the order can address custody, decision-making authority, and child support.³ Children do not lose their legal connection to either parent just because a court later decides the marriage was never valid; Maine’s parentage presumption continues to protect them even when the marriage was invalid, as long as the parties married in apparent compliance with the law.⁸

Either spouse can also request a name change as part of the proceedings. If you want to return to a former name, the court must grant it. If you want a different name entirely, the court has discretion to approve or deny.² Handling it now avoids a separate petition later.

Property is where annulment and divorce part ways. The Maine Judicial Branch’s description of annulment lists custody, child support, and name changes but does not list property division or spousal support among the court’s powers.³ Section 752 does reference spousal support in the context of appeal proceedings, which suggests it may be available in some circumstances.² If you and your spouse own substantial shared property and you need the court to divide it, divorce may be the more practical route even when annulment grounds exist. Talk this through with a lawyer before you file.

Tax, Social Security, and Immigration Consequences

An annulment reaches backward into other parts of your life, and some of the fallout has deadlines.

Federal Taxes

Because the marriage never legally existed, the IRS treats you as unmarried for every year it appeared to be in effect. You must file amended returns on Form 1040-X for all affected tax years still open under the statute of limitations, changing your filing status from married to single or, if you qualify, head of household. The refund window is generally three years from the date you filed the original return or two years from the date you paid the tax, whichever is later.⁹ Whether you end up owing more or getting money back depends on your income; single and married brackets produce different liabilities.

Social Security

The Social Security Administration treats void marriages and annulled voidable marriages differently. A void marriage is treated as if you never married, and it will not terminate or prevent eligibility for child’s or parent’s insurance benefits. When a voidable marriage is annulled by a court, benefits can be reinstated beginning no earlier than the month the annulment is granted, but there’s a catch: if the annulment court awards permanent alimony or keeps the power to award it later, you are treated as still married for Social Security purposes and cannot regain eligibility for parent’s or child’s benefits.¹⁰ Reinstatement is not automatic. You have to file a timely application after the decree is issued.¹¹

Immigration

If either spouse holds a conditional green card based on the marriage, an annulment creates serious complications. Conditional residents normally file Form I-751 jointly with their spouse to remove the two-year condition, and that joint route is obviously unavailable after an annulment. USCIS offers a waiver of the joint filing requirement for marriages terminated by annulment, but only if the conditional resident can prove the marriage was entered into in good faith and not to evade immigration laws.¹² Supporting evidence includes joint bank account records, shared leases, and birth certificates of children. Failing to file the waiver or coming in with weak evidence can cost the conditional resident their status. Anyone in this situation should talk to an immigration attorney before the annulment is finalized, because the timing and documentation strategy matter a great deal.
