Yes, you can get a marriage annulment in New Hampshire, but only if your marriage falls into one of four narrow categories: bigamy, a prohibited family relationship, fraud that struck at something essential to the marriage itself, or a marriage involving a minor without the legally required consent. If your situation doesn’t match one of those grounds, New Hampshire’s divorce process is almost certainly your path forward, not annulment.
Before you do anything else, take these steps:
If your facts genuinely fit one of the statutory grounds, talk to a lawyer before you file. Lydon Law works with clients across New Hampshire on exactly these cases, and a short consultation can save you months of wasted court time if annulment isn’t actually available to you.
New Hampshire limits marriage annulment to four narrow statutory grounds, and filing requires the NHJB-2245-F petition, a heavier burden of proof than divorce, and often legal guidance to assess eligibility correctly.
| Point | Details |
|---|---|
| Only four grounds qualify | Bigamy, prohibited relationships, essential-duty fraud, or a minor married without required consent. |
| Use the correct form | File the Petition to Annul Marriage, NHJB-2245-F, with your county’s Circuit Court Family Division. |
| Burden of proof is higher | You must prove the marriage was legally defective from the start, not simply that it failed. |
| Children stay protected | Courts retain full authority over custody and support regardless of annulment outcome. |
| Get a case review first | Lydon Law can assess whether your facts meet a statutory ground before you file anything. |
An annulment declares that your marriage never legally existed. Divorce, by contrast, ends a marriage that was valid when it happened. That distinction sounds technical, but it changes almost everything about how your case gets handled in court.
New Hampshire courts treat an annulled marriage as void from the start, sometimes called void ab initio, a legal term meaning “from the beginning.” Divorce, governed under the same broad statutory umbrella, Title XLIII, Chapter 458, assumes the marriage was real and simply dissolves it going forward.
Here’s how the two diverge in practice:
Statute check: New Hampshire’s annulment framework sits within RSA Chapter 458, while the specific list of prohibited marriages lives in the RSA 457 series. Both are worth reading if you want the precise statutory language behind your case, and both are cited later in this guide with direct links.
The FindLaw summary of New Hampshire’s annulment and prohibited marriage laws describes annulment as a judge-granted remedy that treats a marriage as though it never occurred at all, which is a useful way to picture what the court is actually doing when it grants one.
New Hampshire limits annulment to four statutory grounds, and courts apply them narrowly. This isn’t a state where you can annul a marriage simply because it didn’t work out or because you regret the decision.
Common misconception to avoid: Lying about wealth, job status, or even past relationships almost never qualifies as annulment-level fraud in New Hampshire. Courts consistently distinguish between fraud that goes to the core of the marital relationship and ordinary deception that people sometimes engage in during courtship. If your spouse exaggerated their income before the wedding, that’s a painful discovery, but it’s not grounds for nullity.
Filing starts with one document: the Petition to Annul Marriage, form NHJB-2245-F, filed with your county’s Circuit Court Family Division. Here’s the process from start to finish.
Filing fees reported by Divorce can change, so confirm the current amount with your county court before you file.
A few practical notes: bring a certified copy of your marriage certificate, keep any prior divorce decrees organized, and if you’re relying on witness testimony, get names and contact information locked down early. Sworn affidavits carry real weight in these cases, and disorganized evidence is one of the fastest ways to slow down an otherwise straightforward petition.
Annulment carries a heavier burden of proof than divorce. In a no-fault divorce, you simply need to show the marriage is over. In an annulment case, you need to prove the marriage was legally defective the moment it began, and that’s a fundamentally different, harder standard to meet.
What courts look for varies by ground:
Timelines vary widely. An uncontested annulment with clean documentation might resolve in a few months. A contested case, especially one involving children, disputed evidence, or an appeal, can stretch well beyond that. DivorceNet’s overview of New Hampshire annulment basics makes a point worth repeating: annulment is often mistaken for a faster shortcut around divorce, when in practice the higher evidentiary bar frequently makes it slower.
Pro Tip: Start gathering documents the moment you suspect a statutory ground applies. Marriage certificates, prior divorce paperwork, and witness names are far easier to collect now than six months into a contested filing.
Most people who ask about annulment are actually better served by divorce, and it’s worth being honest about that upfront. Annulment is the right tool in a narrow set of circumstances; divorce is the tool that actually protects most people’s financial and legal interests.
If property division is a real concern in your situation, our guide on how property gets divided in a New Hampshire divorce walks through the equitable distribution rules that annulment typically doesn’t touch. And if you’re still weighing your overall options, our complete guide to divorce in NH covers the full process from filing to final decree.
New Hampshire’s jurisdictional reach for annulment is broader than many people expect. Under RSA Chapter 458, you can typically file where you or your spouse currently lives. But New Hampshire courts can also declare a marriage void when it was solemnized in New Hampshire, even if neither spouse lives in the state anymore.
That matters for couples who married here on a whim, at a scenic venue or during a weekend trip, and later split up while living elsewhere. New Hampshire’s courts may still have the authority to grant the annulment.
Children complicate the picture, but not in the way people often assume. Annulment doesn’t strip children of legitimacy, and it doesn’t strip the court of authority over custody or support. Under the NH Circuit Court Family Division’s scope rules, the Family Division handles custody and support alongside an annulment petition exactly as it would in a divorce. A void marriage doesn’t create a legal vacuum for kids caught in the middle.
If custody questions are part of your situation, our step-by-step guide to child custody in New Hampshire covers how courts weigh these decisions independent of whether the underlying marriage was annulled or dissolved.
Annulment cases land on our desks less often than divorces, but when they do, they tend to be emotionally charged and legally unusual. I’ve represented clients across New Hampshire courts, including matters that reached the state’s Supreme Court, and the annulment cases I’ve worked on almost always involve a client who needs someone to look at the facts honestly and tell them whether the statutory grounds actually apply. That honesty matters more than optimism here. New Hampshire’s narrow grounds mean a lot of people who want an annulment don’t legally qualify for one, and a good attorney will tell you that early rather than after you’ve filed and paid fees for a petition that won’t hold up.
What I’ve found is that clients do best when they come in with documentation already organized and a clear sense of what outcome they actually need, whether that’s the marriage erased from the record or a faster resolution than divorce might offer. If your facts genuinely fit bigamy, a prohibited relationship, qualifying fraud, or a minor-consent issue, we can help you build the case. If they don’t, we’ll tell you that too, and help you figure out whether divorce is the better route for your circumstances.
Lydon Law is a boutique firm built for exactly these situations, cases where the legal path forward isn’t obvious and the stakes feel personal. Unlike larger firms where you might get passed between staff, you work directly with your attorney from the first consultation through resolution, whether that means filing an annulment petition, contesting one, or pivoting to divorce once we’ve reviewed your facts.
A first consultation typically involves a review of your documentation, an honest assessment of whether your situation meets one of New Hampshire’s statutory grounds, and a clear explanation of next steps and likely costs before you commit to anything. We handle petition drafting, evidence gathering, courtroom representation, and negotiation where a settlement makes more sense than a contested hearing.

Bigamy and fraud concerning an essential marital duty are among the most frequently cited grounds in New Hampshire, though prohibited family relationships and marriages involving minors without consent are also statutory grounds.
No, New Hampshire follows equitable distribution, meaning courts divide marital property based on fairness factors rather than a strict half-and-half formula; this framework generally doesn’t apply in annulment cases since no valid marital estate is recognized.
New Hampshire doesn’t set a fixed deadline tied to how long you’ve been married; what matters is whether a qualifying statutory ground, like bigamy or fraud discovered later, actually exists, and how quickly you act once you learn the facts.
Infidelity isn’t grounds for annulment, and while New Hampshire allows fault-based divorce filings, most cases proceed on no-fault grounds; if you’re unsure which approach fits your situation, Lydon Law’s family law team can walk you through the options.
