New Hampshire offers two distinct legal pathways to end a marriage: annulment and divorce. Annulment under RSA 458 declares a marriage void from inception, treating it as though it never legally existed, while divorce under RSA 458:7-a dissolves a valid marriage through irreconcilable differences. The filing fee for divorce in New Hampshire is $250 without minor children and $282 with minor children as of March 2026. Annulment grounds are strictly limited to fraud, bigamy, prohibited family relationships, or marriages involving minors without parental consent. More than 90% of New Hampshire divorces are granted on no-fault grounds, making annulment a rare legal remedy reserved for marriages with fundamental defects.

What Is an Annulment in New Hampshire
An annulment in New Hampshire is a court decree declaring that a marriage was never legally valid, effectively erasing the marriage from legal existence as though the wedding ceremony never occurred. Under New Hampshire law Title XLIII, Chapter 458, annulment grounds require proof that the marriage suffered from a fundamental legal defect at its inception, such as fraud, duress, bigamy, or a prohibited family relationship. Unlike divorce, which acknowledges that a valid marriage existed and then dissolved, annulment treats the union as void ab initio (void from the beginning). New Hampshire courts apply a strict standard for annulment, requiring that fraudulent representations concern something essential to the marriage relation, not merely character, wealth, or social position.
New Hampshire recognizes two categories of defective marriages that may qualify for annulment. Void marriages are automatically invalid by operation of law under RSA 457:2, such as marriages between close relatives or bigamous unions, and technically require no court action to invalidate. Voidable marriages are valid until a court declares them annulled, such as marriages induced by fraud or involving minors without proper consent. As of January 1, 2025, New Hampshire prohibits all marriages involving persons under age 18 under the updated RSA 457:4, eliminating the prior exception for parental consent.
How Annulment Differs from Divorce
The fundamental difference between annulment and divorce in New Hampshire lies in their legal effect: divorce ends a valid marriage that existed, while annulment declares no valid marriage ever occurred. In divorce proceedings under RSA 458:16-a, courts divide marital property equitably with a 50/50 presumption and may award alimony based on 15 statutory factors. Annulment proceedings do not follow the same property division framework because, legally speaking, there was no marriage during which marital property could accumulate. However, New Hampshire courts retain jurisdiction to address property issues, alimony, and child custody even in annulment cases when equity requires.
| Factor | Annulment | Divorce |
|---|---|---|
| Legal Effect | Marriage never existed | Marriage existed and ended |
| Grounds Required | Fraud, bigamy, prohibited marriage, minor | Irreconcilable differences (no-fault) |
| Property Division | Not automatic; court discretion | Equitable distribution under RSA 458:16-a |
| Alimony Available | Yes, if court orders | Yes, under RSA 458:19 |
| Children Legitimacy | Children remain legitimate | Children legitimate |
| Religious Significance | May allow remarriage in church | Depends on religion |
| Marital Status After | Never legally married | Divorced |
| Time Limit to File | None specified, but sooner is stronger | None |
Both annulment and divorce in New Hampshire require filing with the Circuit Court Family Division and payment of identical filing fees ($250-$282). Service of process requirements also remain the same: the petitioner must have an adult other than themselves hand-deliver the petition to the respondent. The primary practical difference is the burden of proof: divorce requires only a statement that irreconcilable differences caused the irremediable breakdown of the marriage, while annulment demands specific evidence of fraud, duress, bigamy, or another qualifying ground.
Grounds for Annulment in New Hampshire
New Hampshire law restricts annulment to four specific circumstances where the marriage was legally defective from inception. Fraudulent inducement to marry requires proof that one spouse deceived the other about something essential to the marriage relationship, not merely personal characteristics like wealth or social standing. Bigamy occurs when one spouse was already legally married to another person at the time of the wedding ceremony. Prohibited family relationships under RSA 457:2 include marriages between parents and children, siblings, aunts/uncles and nieces/nephews, and first cousins. Finally, marriages involving minors under age 18 without proper consent are now categorically void under the 2025 amendment to RSA 457:4.
The fraud standard for New Hampshire annulment is both strict and stringent according to established case law. Fraudulent representations must concern something making impossible the performance of marital duties and obligations, or rendering the marriage assumption dangerous to health or life. Courts have consistently held that misrepresentations about character, morality, habits, wealth, or social position are insufficient grounds for annulment. Examples of fraud sufficient for annulment include: concealing an inability to consummate the marriage, hiding a criminal history involving violence, or misrepresenting immigration status to obtain legal benefits.
Grounds for Divorce in New Hampshire
New Hampshire provides both no-fault and fault-based grounds for divorce, with more than 90% of divorces granted on irreconcilable differences under RSA 458:7-a. The no-fault ground requires only that irreconcilable differences have caused the irremediable breakdown of the marriage, with no requirement to prove misconduct or any separation period before filing. In no-fault proceedings, allegations or evidence of specific acts of misconduct are improper and inadmissible unless parental rights are at issue and the evidence is relevant to child welfare.
Fault-based grounds under RSA 458:7 include nine specific categories: impotency of either party, adultery, extreme cruelty, conviction of a crime punishable by more than one year imprisonment, treatment seriously injuring health or endangering reason, absence for two years without being heard of, habitual drunkenness for two or more years, habitual drug abuse for two or more years, or joining a religious sect that considers marriage unlawful and refusing to cohabit for six months. Proving fault may influence property division and alimony awards, as fault is one of the 15 factors courts consider under RSA 458:16-a.
New Hampshire Residency Requirements
RSA 458:5 establishes three pathways for establishing jurisdiction in a New Hampshire divorce or annulment. If both spouses are domiciled in New Hampshire, either may file immediately with no durational requirement. If only the filing spouse lives in New Hampshire and the other spouse can be personally served within the state, jurisdiction exists immediately. If the filing spouse is the sole New Hampshire resident and cannot serve the other spouse in-state, the filer must have been domiciled in New Hampshire for at least one year before filing.
For annulment specifically, New Hampshire courts have broader jurisdictional authority. Under RSA 458, in any proceedings for annulment for any cause whether under statute or common law, the court shall have jurisdiction to declare an annulment of a marriage entered into in New Hampshire even though neither party has been at any time a resident of the state. This means couples who married in New Hampshire can seek annulment there regardless of current residency, a unique provision not available for divorce proceedings.
Filing Process for Annulment
To file for annulment in New Hampshire, the petitioner must complete and file a Petition to Annul Marriage with the Circuit Court Family Division in the county where either spouse resides. The filing fee is identical to divorce: $250 without minor children or $282 with minor children as of March 2026. The petition must identify both parties, describe the circumstances of the marriage, and specify the legal ground for annulment with supporting facts. Unlike divorce petitions that simply allege irreconcilable differences, annulment petitions must contain detailed allegations of fraud, duress, bigamy, or the specific prohibited relationship.
Service of process requires an adult other than the petitioner to hand-deliver the petition to the respondent spouse. If the respondent agrees to the annulment, the court may enter a decree without a hearing. If the respondent contests the annulment, the court will schedule a hearing where both parties must testify and present evidence. The petitioner bears the burden of proving the annulment ground by a preponderance of the evidence. Courts will scrutinize fraud claims carefully, requiring specific evidence of material misrepresentation rather than general complaints about the spouse's character or behavior.
Filing Process for Divorce
New Hampshire divorce begins with filing a Petition for Divorce with the Circuit Court Family Division, costing $250 without minor children or $282 with minor children. The petition must identify both parties, describe any children of the marriage, state the grounds for divorce (typically irreconcilable differences under RSA 458:7-a), and outline requests for property division, alimony, and parenting arrangements. Service of process follows the same rules as annulment.
Parents of minor children must complete the Child Impact Program within 45 days of filing, a four-hour educational seminar costing approximately $60-$100 per parent. This mandatory program under RSA 458-D addresses the effects of divorce on children, co-parenting communication strategies, and conflict reduction techniques. The court requires a certificate of attendance before proceeding with the divorce. Additionally, all divorces involving minor children require a signed parenting plan addressing custody, visitation schedules, and decision-making authority.
Property Division Differences
New Hampshire follows equitable distribution under RSA 458:16-a with a statutory presumption that an equal 50/50 division is equitable. Unlike most equitable distribution states, New Hampshire takes an all property approach where courts can divide any asset owned by either spouse regardless of when or how it was acquired. This means inherited property, gifts, and assets owned before marriage are all presumptively divisible, though the court considers these factors when determining whether to deviate from equal division.
In annulment proceedings, property division operates differently because the legal premise is that no valid marriage existed. Courts retain discretion to address property issues equitably but do not apply the same presumptive 50/50 framework. Assets typically remain with their titled owner unless equity requires a different result. This distinction creates significant financial implications: a spouse who contributed to the other's asset accumulation during a lengthy annulled marriage may receive less protection than in divorce. For this reason, divorce is often the more financially protective option even when annulment grounds technically exist.
Alimony and Support Considerations
New Hampshire courts may award alimony in both divorce and annulment proceedings under RSA 458:19. The statute defines three types of alimony: term alimony (for a limited period), reimbursement alimony (to compensate for educational or career support), and permanent alimony (in marriages lasting 20+ years or involving serious disability). Courts consider factors including the length of the marriage, each spouse's income and earning capacity, the standard of living during the marriage, and contributions to the other spouse's education or career.
A party may request alimony in annulment proceedings by filing a motion within five years of the decree of nullity. However, the practical application differs from divorce because the marriage duration factor is measured against a marriage the court has declared legally nonexistent. Courts balance this paradox by considering the period of cohabitation and reliance when equity requires support. For marriages where annulment grounds exist but the couple lived together for an extended period, pursuing divorce rather than annulment may provide more predictable alimony outcomes.
Children and Custody After Annulment
Children born during an annulled marriage remain legitimate under New Hampshire law, entitled to the same rights regarding custody, support, and inheritance as children of divorced parents. Both annulment and divorce proceedings require parenting plans addressing physical custody, legal decision-making authority, and visitation schedules. Courts determine custody based on the best interests of the child under RSA 461-A, considering factors such as each parent's relationship with the child, the child's adjustment to home and community, and each parent's ability to support the child's relationship with the other parent.
Child support obligations apply equally to annulled and divorced parents. New Hampshire calculates child support using income shares methodology under RSA 458-C, considering both parents' gross incomes, the number of children, and adjustments for health insurance, childcare, and parenting time credits. The annulment versus divorce distinction has no effect on child support calculations because parental obligations arise from the parent-child relationship, not the marital relationship.
Timeline and Cost Comparison
Uncontested divorces in New Hampshire typically finalize within 2 to 3 months from filing, while contested divorces may take 12 to 18 months depending on complexity and court scheduling. Annulment timelines vary more significantly because the petitioner must prove specific grounds rather than simply alleging marital breakdown. A contested annulment requiring evidence of fraud may take 6 to 12 months for an initial hearing, with possible appeals extending the process further.
| Cost Category | Annulment | Divorce |
|---|---|---|
| Filing Fee (no children) | $250 | $250 |
| Filing Fee (with children) | $282 | $282 |
| Child Impact Program | $60-$100/parent | $60-$100/parent |
| Attorney Fees (uncontested) | $2,000-$5,000 | $2,000-$5,000 |
| Attorney Fees (contested) | $10,000-$44,000+ | $10,000-$44,000+ |
| Credit Card Surcharge | 3% on all payments | 3% on all payments |
Fee waivers are available for individuals who cannot afford filing fees through applications available at the courthouse or the New Hampshire Judicial Branch website. All credit and debit card payments incur an additional 3% processing surcharge. Additional costs may include process server fees ($50-$150), mediation costs ($200-$500 per session), and expert witness fees if complex property valuation or fraud allegations require professional testimony.
When to Choose Annulment vs. Divorce
Choosing between annulment and divorce in New Hampshire depends on three primary factors: whether valid annulment grounds exist, religious or personal preferences regarding marital status, and financial implications of each pathway. Annulment may be preferable when: the marriage involved documented fraud affecting essential marital duties, one spouse was already legally married, the parties are closely related, or the marriage occurred without proper consent (such as involving a minor under current law).
Divorce is typically the better choice when: the marriage was legally valid despite current unhappiness, property division protections matter significantly, alimony claims require the framework of RSA 458:16-a and RSA 458:19, or annulment grounds cannot be proven by sufficient evidence. Even when annulment grounds exist, many New Hampshire attorneys advise divorce because the equitable distribution framework provides clearer property protections and the process moves more predictably through the court system.
Frequently Asked Questions
How long do I have to file for annulment in New Hampshire?
New Hampshire law does not impose a specific time limit for filing annulment petitions, but courts expect prompt action once grounds become known. Filing immediately after discovering fraud, bigamy, or another annulment ground strengthens the petition by demonstrating that the innocent spouse did not ratify the marriage by continuing to cohabit after learning the truth. Waiting years to file may weaken the case and shift available remedies toward divorce.
Can I get an annulment in New Hampshire if my spouse lied about their finances?
Misrepresentations about wealth, income, or financial status are generally insufficient grounds for annulment under New Hampshire law. Courts apply a strict fraud standard requiring that the deception concern something essential to the marriage relationship, making impossible the performance of marital duties or endangering health or life. Lies about character, wealth, or social position do not meet this threshold. Divorce with fault-based grounds may address financial misconduct through property division.
What happens to property in a New Hampshire annulment?
Unlike divorce, annulment does not trigger automatic equitable distribution under RSA 458:16-a because the court declares no valid marriage existed. Property generally remains with the titled owner unless the court exercises discretion to achieve equity. Spouses who acquired significant joint assets during an annulled marriage may receive less property protection than in divorce, making divorce the preferred option when substantial assets exist.
Does an annulment affect my children's legitimacy in New Hampshire?
Children born during an annulled marriage remain legitimate under New Hampshire law with full rights to custody arrangements, child support, and inheritance from both parents. The annulment affects only the marital relationship between the parents, not the parent-child relationship. Courts address custody, visitation, and support using the same best interests standards applied in divorce under RSA 461-A.
Can I get alimony after an annulment in New Hampshire?
Yes, New Hampshire courts may award alimony in annulment proceedings under RSA 458:19. A party may request alimony by filing a motion within five years of the decree of nullity. However, the framework differs from divorce because courts must balance support factors against the legal premise that no valid marriage existed. Practical cohabitation periods and financial reliance may inform the court's discretion.
What is the filing fee for annulment in New Hampshire?
The filing fee for annulment in New Hampshire is $250 without minor children and $282 with minor children as of March 2026. These fees are identical to divorce filing fees. All credit and debit card payments incur an additional 3% processing surcharge. Fee waivers are available for individuals who cannot afford the filing fee through applications at the courthouse or the New Hampshire Judicial Branch website.
How long does an annulment take in New Hampshire?
Annulment timelines in New Hampshire vary based on whether the respondent contests the petition. If both parties agree to the annulment, the court may enter a decree without a hearing, potentially finalizing within 2-3 months. Contested annulments requiring evidentiary hearings may take 6-12 months for initial resolution, with appeals potentially extending the process. Complex fraud allegations requiring expert testimony take longer than straightforward void marriage cases.
Can I get my marriage annulled if we were married less than a year?
The duration of the marriage does not determine annulment eligibility in New Hampshire. Annulment requires proof of specific legal defects: fraud essential to the marriage, bigamy, prohibited family relationship, or marriage involving a minor without proper consent. A short marriage may provide circumstantial support for fraud claims (suggesting the petitioner acted promptly upon discovering the deception), but duration alone is not a qualifying ground.
What grounds allow fault-based divorce in New Hampshire?
RSA 458:7 provides nine fault-based divorce grounds: impotency, adultery, extreme cruelty, conviction of a crime punishable by more than one year, treatment seriously injuring health, absence for two years without contact, habitual drunkenness for two or more years, habitual drug abuse for two or more years, or joining a religious sect that rejects marriage and refusing to cohabit for six months. Proving fault may affect property division and alimony awards.
Is a religious annulment the same as a legal annulment?
Religious and legal annulments are separate processes with different requirements and effects. A religious annulment from a church allows remarriage within that faith but has no legal effect on marital status, property rights, or custody. A legal annulment from New Hampshire courts affects legal marital status and related rights but may not satisfy religious requirements. Individuals seeking both must complete separate processes with their religious authority and the civil court system.
