New Hampshire Divorce Laws (2026): Grounds, Residency, and Process

New Hampshire grants divorce on the no-fault ground of irreconcilable differences causing an irremediable breakdown of the marriage under RSA 458:7-a. There is no mandatory separation period and no cooling-off waiting period before a decree may enter. Residency rules depend on whether the defendant is served in-state.
Grounds for divorce in New Hampshire
New Hampshire recognizes both no-fault and fault-based grounds for divorce. The no-fault ground, codified at RSA 458:7-a, is irreconcilable differences causing the irremediable breakdown of the marriage. Either spouse may invoke this ground without proving fault or misconduct, and the other spouse cannot legally block the divorce by denying irreconcilable differences exist.
Fault grounds remain available under RSA 458:7 for spouses who wish to raise misconduct. Those grounds include adultery, extreme cruelty, imprisonment for more than one year, absence for two or more years without being heard from, habitual abuse of alcohol or drugs for 2 or more years together, and willful abandonment for two or more years. Raising a fault ground is optional; most New Hampshire divorces proceed on irreconcilable differences because it avoids the burden of proving wrongdoing and tends to reduce conflict.
Using a fault ground does not automatically result in a larger share of marital property, though a court may consider certain conduct when dividing assets or awarding alimony in appropriate circumstances.
Residency requirement
New Hampshire's residency rules under RSA 458:5 are more flexible than most states and depend on where the parties are located at the time of filing. If both spouses are domiciled in New Hampshire, the plaintiff may file immediately with no minimum residency period. If only the plaintiff is domiciled in New Hampshire but the defendant can be personally served with process within the state, the plaintiff may also file without satisfying any minimum residency period.
A one-year domicile requirement applies in the narrower circumstance where the plaintiff is domiciled in New Hampshire but the defendant is not served with process within the state. In that situation, the plaintiff must have been domiciled in New Hampshire for at least one year before the complaint is filed.
All divorce actions are heard in the Circuit Court, Family Division, in the county where either party resides. New Hampshire's unified family court structure means the same judge handles all related family matters, including parenting, child support, and alimony, within the same proceeding.
Waiting period and separation
New Hampshire has neither a mandatory waiting period nor a separation requirement, which distinguishes it from many other states. A waiting period (sometimes called a cooling-off period) is a minimum number of days that must pass after filing before the court can enter a final divorce decree. New Hampshire imposes no such delay: an uncontested divorce can be finalized as soon as the court processes the paperwork and a hearing is scheduled.
A separation requirement is a different clock entirely. Some states require spouses to live in separate households for a defined period before they can even file or before a no-fault decree can be granted. New Hampshire has no such requirement. Spouses may be living together under the same roof at the time of filing and throughout the proceeding.
In practice, the length of a New Hampshire divorce depends almost entirely on whether it is contested. An uncontested divorce where the parties reach a full agreement on all issues (property, parenting, support) can be finalized within a few weeks to a few months. A contested divorce requiring trial may take a year or more.
How property is divided
New Hampshire is an equitable distribution state, not a community property state. Community property (the rule in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) generally splits marital assets and debts 50/50 between spouses. Equitable distribution, by contrast, divides marital property in a manner the court determines is fair and just under all of the circumstances, which often results in an equal split but need not.
Under RSA 458:16-a, New Hampshire courts begin with a presumption that an equal division of marital property is equitable, but either party can rebut that presumption by showing factors that justify a different allocation. Those factors include the length of the marriage, each spouse's age and health, each spouse's occupation and employability, each spouse's income and earning capacity, the contribution of each spouse to the acquisition of marital assets (including homemaking and child-rearing), the market value and tax consequences of the assets, and fault where relevant.
Only marital property is subject to division. Separate property, meaning assets owned before marriage or received during the marriage by gift or inheritance and kept separate, generally remains with the owning spouse. However, separate property that has been commingled with marital funds or that the other spouse has contributed to can sometimes become partially or fully marital in character. If separate assets were mixed with marital funds, get a free case evaluation from a New Hampshire family lawyer on tracing them before the property is divided (attorney advertising).
Alimony, custody, and child support
Alimony, parental rights and responsibilities (New Hampshire's term for legal and physical custody), and child support are all addressed as part of the divorce process in the Circuit Court, Family Division. None of these issues must be resolved before the divorce itself is granted, but they are almost always decided in parallel or in the same judgment.
Term alimony in New Hampshire is governed by RSA 458:19-a. The court first makes the threshold findings in paragraph I: that the party seeking alimony lacks sufficient income or property to meet reasonable needs and cannot be self-supporting, and that the other party can meet the request while still meeting their own reasonable needs.
The amount is then set by the formula in RSA 458:19-a, II(a), which has governed since January 1, 2019. A term alimony order is the lesser of the payee's reasonable need or 23 percent of the difference between the parties' gross incomes at the time the order is created, unless the court finds that justice requires an adjustment. If alimony becomes deductible to the payor and taxable to the payee under federal income tax law, the formula uses 30 percent of that difference instead. For a full breakdown of alimony rules, amounts, and duration, see the New Hampshire alimony laws page.
Child custody (parental rights and responsibilities) focuses on the best interests of the child under RSA 461-A. The court may award joint or sole legal and physical responsibility. Child support is calculated under the New Hampshire Child Support Guidelines (RSA 458-C). The guideline obligation is built from the parents' combined net income and the number of children, applied through the percentage table in RSA 458-C:3. Parenting time is not an input to that formula; it can support a deviation from the guideline amount under RSA 458-C:5, including where the parents share approximately equal residential responsibility. Estimate your payment with our New Hampshire child support calculator. See the New Hampshire child custody laws page and the child support resources for detailed coverage.
How to file for divorce in New Hampshire
Filing for divorce in New Hampshire follows a straightforward procedural sequence, though contested cases add complexity at each step.
First, confirm that you meet the residency requirements under RSA 458:5. In most cases where both spouses live in New Hampshire, there is no minimum waiting period before you can file.
Second, prepare and file a Petition for Divorce (or, if the marriage has not been consummated or is voidable, a Petition for Nullity or Annulment) in the Circuit Court, Family Division, in the county where you or your spouse resides. New Hampshire's court system provides self-help forms through the NH Judicial Branch website for uncontested cases.
Third, serve your spouse with the divorce petition and a summons. Personal service by a sheriff or process server is standard; the defendant then has a set number of days to file an answer.
Fourth, both parties must exchange financial disclosures, including income, assets, debts, and expenses. These disclosures are mandatory and must be completed before any final orders on property, alimony, or support.
Fifth, if the case is uncontested, the parties submit a Permanent Stipulation (marital settlement agreement) covering all issues. The court reviews the agreement to ensure it is equitable, holds a brief final hearing, and enters the divorce decree. If the case is contested, it proceeds through mediation (often required by the court), pretrial conferences, and ultimately a trial before a judge.
The final divorce decree, called a Final Decree of Divorce, terminates the marriage and incorporates all orders on property, alimony, parenting, and support.

Frequently Asked Questions
How long does it take to get a divorce in New Hampshire?
New Hampshire has no mandatory waiting period, so timeline depends on whether the divorce is contested. An uncontested divorce where both parties agree on all issues can be finalized in as little as a few weeks to a couple of months once paperwork is processed and a hearing is scheduled. A contested divorce requiring trial can take a year or more.
How much does a divorce cost in New Hampshire?
Court filing fees vary by county but are typically in the range of a few hundred dollars. Attorney fees depend on the complexity of the case and the degree of conflict. An uncontested divorce handled with limited-scope representation or self-help forms costs far less than a litigated contested divorce, which can run into thousands of dollars in attorney fees.
Do I need a reason to divorce in New Hampshire?
No. New Hampshire allows divorce on the no-fault ground of irreconcilable differences (RSA 458:7-a). You do not need to prove your spouse did anything wrong. Simply stating that irreconcilable differences have caused an irremediable breakdown of the marriage is sufficient.
Is New Hampshire a community property state?
No. New Hampshire is an equitable distribution state. Courts divide marital property in a way that is fair and just given all the circumstances, starting with a presumption of equal division under RSA 458:16-a. The result is often equal, but not always.
How long do I have to be separated to divorce in New Hampshire?
New Hampshire has no separation requirement. You do not need to live apart from your spouse before filing or during the divorce process. Spouses can be living together at the time of filing and still proceed on irreconcilable differences.
Can I get divorced without my spouse agreeing in New Hampshire?
Yes. Because New Hampshire allows no-fault divorce on irreconcilable differences, one spouse's refusal to agree does not prevent the divorce. The case becomes contested, meaning the court will decide disputed issues at trial, but the divorce itself will ultimately be granted.
Do I have to live in New Hampshire to file for divorce here?
Generally yes. You must be domiciled in New Hampshire. If both spouses live in NH, you can file immediately. If your spouse is not in NH and cannot be served in-state, you must have been domiciled in NH for at least one year before filing (RSA 458:5).
Updates
Corrected the habitual substance abuse divorce ground to match RSA 458:7, VII (2 or more years, no financial-injury element), moved the alimony discussion to the operative statute RSA 458:19-a and added its 23 percent gross-income-difference formula, and corrected the child support guideline inputs to combined net income and number of children, with parenting time noted as a deviation factor.
