New Hampshire offers both no-fault and fault-based grounds for divorce, giving filing parties flexibility in how they approach the process. The state requires a one-year residency period before filing, follows equitable distribution principles for property division, and provides a structured process that — while not as fast as states like Nevada — can be straightforward for couples who agree on key issues. Understanding the residency rules, available grounds, and procedural steps will help you navigate a New Hampshire divorce efficiently.

Residency Requirements

New Hampshire has specific residency requirements that must be met before the court will accept a divorce filing. Under RSA 458:5, the rules depend on whether both parties live in the state:

If both spouses are domiciled in New Hampshire, either spouse may file. If only the filing party resides in New Hampshire, that party must have been domiciled in the state for at least one year before filing. If only the responding party lives in New Hampshire and is personally served within the state, the court may exercise jurisdiction — provided the filing party has been domiciled in New Hampshire for at least one year or the cause of the divorce arose in the state.

New Hampshire Law
Under RSA 458:5, "domicile" means more than physical presence — it requires the intent to make New Hampshire your permanent home. Simply renting a temporary residence for the purpose of filing does not establish domicile. Evidence of domicile includes voter registration, driver's license, property ownership, employment, and community ties.

Military Exception

Members of the armed forces stationed in New Hampshire are considered domiciled in the state for purposes of divorce jurisdiction, even if their permanent home of record is in another state, provided they have been stationed in New Hampshire for at least one year.

No-Fault Ground: Irreconcilable Differences

The most commonly used ground for divorce in New Hampshire is irreconcilable differences under RSA 458:7-a. This no-fault ground requires only that the spouses state their marriage has broken down and there is no reasonable prospect of reconciliation.

To file on this ground:

  • Either spouse can file by stating irreconcilable differences in the petition
  • No proof of misconduct is required
  • If both parties agree that irreconcilable differences exist, the process is straightforward
  • If one party contests the assertion, the court will evaluate the evidence and make a determination

The no-fault ground is used in the vast majority of New Hampshire divorces because it avoids the cost, time, and emotional burden of proving fault.

Fault-Based Grounds

New Hampshire also recognizes several fault-based grounds for divorce under RSA 458:7. These include:

Impotence

If a spouse was impotent at the time of the marriage and the condition was unknown to the other spouse, this constitutes a ground for divorce.

Adultery

Adultery — voluntary sexual intercourse between a married person and someone other than their spouse — is a recognized ground. The filing spouse must present sufficient evidence to prove the adultery occurred.

Extreme Cruelty

Extreme cruelty includes conduct that endangers the life, health, or well-being of the other spouse. This can encompass:

  • Physical violence or abuse
  • Persistent verbal or emotional abuse
  • Threats of bodily harm
  • Conduct that creates a pattern of fear or intimidation

Courts evaluate extreme cruelty on a case-by-case basis. A pattern of behavior is more persuasive than a single isolated incident, though a single act of severe violence may be sufficient.

Conviction of a Crime

If a spouse has been convicted of a crime and sentenced to imprisonment, this can serve as a ground for divorce.

Habitual Drunkenness

Habitual drunkenness for a period of two years is a recognized ground. The filing party must demonstrate that the drinking pattern is chronic and ongoing — not merely occasional or social drinking.

Additional fault-based grounds include joining a religious sect that professes the marriage relation to be unlawful and refusing to cohabit for at least six months, absence without communication for at least two years, and treatment that seriously injures health or endangers reason under RSA 458:7(VI) — even if the treatment does not rise to the level of extreme cruelty.

New Hampshire Law
Filing on fault-based grounds in New Hampshire requires proof. The burden falls on the filing party to demonstrate the alleged misconduct by a preponderance of the evidence. While fault grounds can affect alimony decisions, most New Hampshire divorces are filed on the no-fault ground of irreconcilable differences because it is faster, less expensive, and less adversarial.

Filing Fees and Costs

The court filing fee for a divorce in New Hampshire is approximately $250. Additional costs include service of process ($25 to $75), a mandatory parenting class if minor children are involved ($50 to $100 per person), and potential mediation fees. Attorney fees vary widely — an uncontested divorce may cost $1,000 to $3,000, while a contested case can cost $5,000 to $20,000 or more. Fee waivers are available for parties who demonstrate financial hardship.

Equitable Distribution: How New Hampshire Divides Property

New Hampshire is an equitable distribution state. Under RSA 458:16-a, the court divides marital property in a manner that is fair and equitable — but not necessarily equal. This gives the court significant discretion to consider the circumstances of each case.

What Is Marital Property?

New Hampshire defines marital property broadly. Under RSA 458:16-a(I), the court has the power to determine the value of all property — including both marital and separate property — and to divide it equitably. Unlike many states that exclude separate property from division, New Hampshire courts have the authority (though rarely exercised) to include separate property in the distribution if fairness requires it.

Factors the Court Considers

When dividing property, the court considers factors including the duration of the marriage, each party’s age, health, and station, each party’s income, occupation, and vocational skills, each party’s liabilities and needs, the opportunity for future acquisition of capital assets and income, contributions to the acquisition or preservation of assets (including contributions as a homemaker), tax consequences, and any fault that contributed to the breakdown of the marriage.

New Hampshire Law
New Hampshire is unusual among equitable distribution states in that the court technically has the power to divide ALL property owned by either spouse — including separate property such as inheritances and pre-marital assets. Under RSA 458:16-a, the court considers the totality of each party's circumstances. In practice, courts typically treat pre-marital and inherited property more favorably to the owning spouse, but the statute gives judges broad discretion.

The Divorce Process Step by Step

  1. File the Petition — one spouse files a Petition for Divorce with the Family Division of the Circuit Court in the county where either spouse resides, paying the filing fee of approximately $250.
  2. Serve the Other Spouse — the petition must be served on the respondent (typically by sheriff, certified mail, or private process server), who has 30 days to file a response.
  3. Temporary Orders — either party may request temporary orders for custody, child support, spousal support, or use of the marital home while the case is pending.
  4. Mandatory Disclosures — both parties must exchange financial affidavits disclosing all income, assets, debts, and expenses.
  5. Mediation — New Hampshire courts encourage and often require mediation before trial. Many cases settle at mediation.
  6. Final Hearing — if the parties reach agreement, they present it to the court for approval. If not, the case proceeds to trial.
  7. Nisi Period — New Hampshire imposes a nisi period of typically 30 days after the final decree before it becomes absolute. Neither party may remarry during this time.

Alimony in New Hampshire

Under RSA 458:19, the court may award alimony to either spouse based on the circumstances. Factors include the length of the marriage, each spouse’s age and earning capacity, the standard of living during the marriage, the property division awarded, each spouse’s contributions (including homemaking), and whether one spouse’s career was sacrificed for the other’s benefit. Fault can be a factor — if one spouse’s misconduct contributed to the breakdown of the marriage, the court may consider that conduct when determining whether alimony is appropriate and in what amount.

What to Do Next

If you are considering a divorce in New Hampshire, taking the right steps early can help you move through the process more smoothly:

  1. Confirm your residency. Make sure you meet the domicile requirement — at least one year if your spouse does not live in New Hampshire.
  2. Choose your ground carefully. For most people, irreconcilable differences is the simplest and fastest path. Consider fault-based grounds only if there is a strategic reason — such as the potential impact on alimony.
  3. Gather financial records. Collect bank statements, tax returns, retirement account statements, property deeds, mortgage documents, and documentation of debts. Complete financial transparency is required.
  4. Prepare for the parenting class. If you have minor children, both parents must attend a court-approved parenting class.
  5. Consider mediation. New Hampshire courts strongly encourage mediation, and many cases settle without trial. Being open to mediation can save significant time and money.
  6. Consult with an attorney. A New Hampshire family law attorney can help you understand your rights regarding property division, alimony, and custody, and can guide you through the process efficiently.

Frequently Asked Questions

How long does a divorce take in New Hampshire?

An uncontested divorce where both parties agree on all issues can be finalized in approximately 2 to 3 months from filing. Contested cases take significantly longer — typically 6 to 18 months or more, depending on the complexity of the issues and court scheduling. The nisi period adds approximately 30 days after the final hearing.

Can I file for divorce in New Hampshire if my spouse lives in another state?

Yes, as long as you have been domiciled in New Hampshire for at least one year before filing. You must properly serve your spouse with the divorce papers in their state of residence. The court’s authority over out-of-state property and financial matters may be limited.

Does fault affect property division in New Hampshire?

Fault can be a factor in property division under RSA 458:16-a, but it is typically not the primary consideration. Courts focus more heavily on financial factors — income, earning capacity, contributions to the marriage, and the needs of each party. Extreme misconduct, such as dissipation of marital assets, is more likely to influence the court’s property division decision.

A legal separation resolves the same issues as a divorce — property division, custody, support — but the marriage remains legally intact. Some couples choose legal separation for religious reasons, to maintain health insurance benefits, or because they are unsure about permanently ending the marriage. A legal separation can later be converted to a divorce.

Do I need an attorney for a New Hampshire divorce?

While you are not legally required to have an attorney, consulting one is strongly recommended — particularly if your case involves significant assets, disputes over custody, or complex financial issues. Even in an uncontested case, an attorney can ensure your agreement is fair, properly drafted, and protects your interests.
