You can seek an annulment in New Hampshire only if one of the state’s narrow statutory grounds applies to your marriage. Your first step is filing the Petition to Annul Marriage (NHJB-2245-F) with the Circuit Court Family Division. If your circumstances don’t fit those grounds, divorce remains the standard path forward for ending your marriage legally.
TL;DR:
- Annulments in New Hampshire are only granted if the marriage meets strict statutory grounds, such as bigamy, prohibited relationships, fraud, or underage marriage without consent.
- Property division after an annulment relies on contract or equity principles rather than marital laws, and alimony is rarely awarded, with children and support obligations unaffected.
- Filing requires submitting a detailed petition with evidence of the grounds, paying around $250-$282, and properly serving the spouse, with contested cases possibly taking over a year.
- Proof of fraud or misrepresentation must be clear, timely, and supported by documentation like communications or affidavits, as courts require preponderance of evidence.
- Post-annulment, individuals should update their legal records, and debts incurred during the marriage generally remain unless specifically contested in separate proceedings.
An annulment declares that your marriage never legally existed in the first place. Divorce, by contrast, ends a marriage the law recognizes as valid up until that point. That distinction sounds technical, but it shapes everything that follows in your case.
Because an annulled marriage is treated as void from the start, courts approach property and support differently than they would in a divorce. Here’s what typically changes:
If you’ve built significant shared assets or expect to need spousal support, divorce usually offers stronger financial protections, even when annulment grounds technically exist.
New Hampshire courts don’t grant annulments for regret, incompatibility, or a marriage that simply didn’t work out. The grounds are narrow and rooted in specific statutory defects that existed at the time of the marriage.
Statistic Callout: Legal guides tracking NH annulment and divorce outcomes note that annulments make up a small fraction of marital dissolution filings statewide, precisely because the qualifying grounds are so limited compared to the broad “irreconcilable differences” standard used in divorce.
The recognized grounds under RSA Chapter 458 include:
A short marriage or a change of heart doesn’t meet any of these thresholds. The court is looking for a legal defect, not dissatisfaction.
You file a Petition to Annul Marriage in the Circuit Court Family Division in the county where you or your spouse currently reside. New Hampshire’s rules here work a little differently than they do for divorce, which usually surprises people who assume the same residency clock applies to both.
That jurisdictional flexibility matters if you and your spouse have relocated since your wedding but the legal defect (bigamy, a prohibited relationship, lack of consent) traces back to the marriage itself.
Filing an annulment petition follows a fairly linear process, though the timeline depends heavily on whether your spouse contests it; for a broader understanding, see Marriage nullification in UAE: legal meaning, grounds, and process.
Before filing day, gather your marriage certificate, any documentation supporting your grounds, and a list of shared property or debts.
Pro Tip: Bring extra copies of everything to the courthouse. Clerks often need a filing copy, a copy for service, and one for your own records, and running back home for paperwork can cost you weeks on the court’s schedule.
You carry the burden of proving your grounds by a preponderance of the evidence, meaning it’s more likely than not that your claim is true. Courts don’t take these petitions lightly, and general complaints about your spouse’s character won’t move the needle.
For fraud or duress claims specifically, judges want to see that the misrepresentation was material, meaning it struck at the heart of the marital relationship itself, not a minor personal quality you later discovered you disliked. Concealing an existing marriage or misrepresenting something essential to the couple’s shared life falls into this category.
Filing soon after discovery strengthens your case considerably. Waiting years to act on a known fraud can undercut your credibility with the court.
An annulment generally treats the marriage as though it never happened, but that doesn’t mean the court ignores fairness. Judges retain authority to address equitable claims over jointly acquired property or financial contributions even after declaring a marriage void.
Custody and parental rights work differently. Children born during a marriage that’s later annulled still have the same legal protections regarding custody, visitation, and child support as children of any dissolved marriage. Annulment status doesn’t diminish parental obligations or a child’s right to support from both parents.
A respondent facing an annulment petition isn’t without options, and successful defenses can significantly change how a case resolves. The most common defense challenges whether the alleged misrepresentation was actually material to the marriage, rather than a minor issue the petitioner is using to escape an unhappy relationship after the fact.
Ratification is another frequent defense. If the petitioner continued living as a married couple, sharing finances, or holding themselves out publicly as married after discovering the alleged fraud or defect, a court may find they effectively accepted the marriage despite the flaw. This defense can be powerful in cases where months or years passed between discovery and filing.
A respondent may also argue that the statutory ground simply doesn’t apply. For instance, if a petitioner claims bigamy but can’t produce evidence the prior marriage was still legally valid at the time of the second ceremony, the annulment claim collapses. Similarly, a fraud claim can be defeated by showing the petitioner knew the relevant facts before the wedding and proceeded anyway.
Consent-based defenses matter in underage marriage cases too. If proper parental or guardian consent was actually obtained, even if paperwork was later misplaced or disputed, that defense can defeat a petition based on the age of consent provisions in RSA 457.
When a respondent raises a credible defense, cases that seemed straightforward often shift into contested territory, adding months to the timeline and increasing the importance of solid documentation on both sides.
Walking into a Family Division hearing without preparation puts you at a real disadvantage, especially since you carry the burden of proof. Start by organizing your evidence chronologically: when the marriage occurred, when you discovered the issue supporting your grounds, and what you did afterward.
Bring physical and digital copies of every document supporting your claim, including your marriage certificate, communications referencing the misrepresentation, and any affidavits from witnesses. Judges respond well to organized, dated evidence rather than a loose stack of papers handed over mid-testimony.
Expect the judge to ask direct questions about the timeline. Common lines of inquiry include when you learned about the fraud, bigamy, or consent issue, whether you continued living together afterward, and why you’re seeking annulment rather than divorce. Be ready to explain any delay between discovery and filing, since courts weigh promptness heavily when evaluating fraud and duress claims.
If your spouse contests the petition, anticipate cross-examination on the materiality of your claim. The judge wants to understand whether the issue you’re describing truly struck at the essence of your marital relationship, not just a personal disappointment.
Dress and conduct yourself as you would for any formal court proceeding. Address the judge respectfully, answer only what’s asked, and avoid volunteering emotional commentary that doesn’t support your legal grounds. Family Division judges see these cases regularly and respond best to clear, factual testimony.
Once the court issues your decree of nullity, a few practical tasks remain to align your legal records with your new status. These steps matter for everything from your driver’s license to future marriage applications.
If you took your spouse’s last name, you can typically request a name restoration as part of your annulment decree, or through a separate petition afterward. Bring your certified decree to the Department of Motor Vehicles, Social Security Administration, and any financial institutions where your name appears on accounts or policies.
Update your marital status on tax filings, insurance policies, and beneficiary designations tied to retirement accounts or life insurance. Because the law treats an annulled marriage as though it never existed, some institutions require the certified decree as proof before they’ll process these changes.
If you plan to remarry, keep multiple certified copies of your decree on hand. Some town clerks and out-of-state agencies request documentation of your prior marital status when you apply for a new marriage license, and having the paperwork ready avoids delays.
Finally, review any joint accounts, leases, or property titles that still list both names. An annulment doesn’t automatically separate shared finances, so you may need additional paperwork or a separate agreement to fully untangle joint obligations.
Annulment’s void-from-inception nature raises a common misconception: that it erases financial obligations tied to the marriage. It doesn’t work that way in practice.
Debts incurred jointly during the marriage, such as a shared credit card, auto loan, or lease, typically remain the responsibility of whoever signed the agreement or benefited from the funds. Courts can apply equitable principles to sort out who owes what, even though the marriage is treated as never having existed legally.
Spousal support is rarely awarded after an annulment since the law doesn’t recognize an ongoing marital duty to support a spouse from a void marriage. That’s a meaningful difference from divorce, where alimony is often on the table depending on income disparity and length of the relationship. If financial support after separation is a priority for you, this is one of the clearest reasons divorce may serve you better than annulment, even when annulment grounds technically exist.
Child support obligations are unaffected by annulment status entirely. Both parents remain financially responsible for their children regardless of whether the underlying marriage was ever legally valid.
Evaluating whether you have real annulment grounds versus a case better suited to divorce takes a trained eye. An attorney will weigh your evidence against the statutory standard and tell you honestly whether your facts support fraud, duress, bigamy, or a prohibited relationship, rather than letting you file a petition that’s likely to fail.
Bring your marriage certificate, any communications tied to the misrepresentation, prior marriage records if bigamy is at issue, and a written timeline of events to your first consultation. If children are involved or you have safety concerns, raise those immediately. Temporary orders addressing custody or protection can often be requested alongside your petition rather than after the fact.

Yes, but only if your marriage meets one of the narrow statutory grounds under RSA Chapter 458, such as bigamy, prohibited relationships, fraud, duress, or lack of required consent for a minor.
Fraud or material misrepresentation and bigamy (proof that one spouse was already legally married when the ceremony took place) are among the most frequently cited grounds in New Hampshire annulment petitions.
There’s no fixed statutory deadline, but courts expect you to file promptly after discovering the fraud, duress, or other defect. Waiting years without explanation can weaken your case, particularly if you continued living as a married couple.
New Hampshire’s “clean slate” style provisions apply to criminal record annulment, not marriage annulment. Marriage annulment is a separate family law process governed entirely by RSA Chapter 458 and RSA Chapter 457.
