No durational residency at all where both spouses are domiciled in New Hampshire, and no mandatory separation period. New Hampshire does grant legal separation.
New Hampshire divorce law has two features that surprise a lot of people starting out: there's no mandatory separation period before you can file, and the court's power to divide property reaches almost everything either spouse owns — not just what you built together.
| Residency requirement | Three routes (RSA 458:5). No durational requirement at all if both spouses are domiciled in New Hampshire, or if you are domiciled here and your spouse is served within the state. The one-year residency applies only where you alone are domiciled in New Hampshire — so check which situation you are in before assuming you have to wait. |
|---|---|
| Grounds | Most people file on the no-fault ground of 'irreconcilable differences' that have caused the irremediable breakdown of the marriage (RSA 458:7-a) — specific misconduct doesn't need to be proven. Fault grounds are also available (RSA 458:7), including adultery, extreme cruelty, abandonment for two years, and habitual drug/alcohol abuse. |
| Waiting period | No mandatory separation period before filing. The statutes don't set a fixed waiting period before a decree becomes final — ask the clerk whether any nisi/finalization delay applies to your case. |
| Legal separation | New Hampshire does grant legal separation. It settles the same questions a divorce settles — support, parenting and, depending on the case, property — but leaves the marriage in place, so neither spouse can remarry without a divorce. |
| If you were never married | New Hampshire does not create common-law marriage, and living together gives neither partner property or support rights. Claims rest on agreements between you. A common-law marriage validly formed in a state that does create them is generally still recognised. |
| Where you file | Circuit Court – Family Division, in the county where either spouse lives (Family Division sits in 32 locations across NH's 10 counties). |
| Filing fee | Payable when you file your opening divorce document. Set by regulation and revised from time to time. A fee waiver is available if you cannot afford it. Filing fees are set by the court and change without notice: check the current schedule on the court's own website before you file, and ask about a fee waiver if the cost is a barrier. |
| Starting forms | Petition for Divorce (NHJB-2057-F) for one spouse filing alone, or Joint Petition for Divorce (NHJB-2058-F) if both agree, plus the required Personal Data Sheet (NHJB-2077-F) and a Financial Affidavit (NHJB-2065-F) from each party. |
| Simplified option | Yes — a Joint Petition (NHJB-2058-F) avoids formal service when both spouses agree, and uncontested cases with a complete file can qualify for a final hearing 'on the papers' (no court appearance) under Family Division Rule 2.22. |

Divorce in New Hampshire is governed by RSA Chapter 458, and cases are heard in the Circuit Court's Family Division. Unlike a number of neighboring states, New Hampshire does not require spouses to live apart for a set period before filing. You do need to meet the state's residency rules — generally that one spouse is domiciled in New Hampshire, or the marriage took place there and at least one spouse has lived in the state since, or the moving spouse has been domiciled there for a period before filing. The lack of a waiting period doesn't mean divorce is fast, though; contested cases still take time to move through disclosure, negotiation, and court scheduling.
The bigger structural difference is what counts as divisible property. Many states only divide what was earned or acquired during the marriage. New Hampshire courts treat all property owned by either spouse — including what you brought into the marriage, inheritances, and gifts — as part of the marital estate available for equitable distribution. The court starts from a presumption of equal division but can move away from it based on factors like the length of the marriage, each spouse's contributions, and how and when property was acquired. In practice, this means the 'that's mine, I had it before we married' argument works very differently here than it might elsewhere.
Because New Hampshire's all-property rule pulls in assets many people assume are off the table, it's worth documenting premarital and inherited property early — not to shield it, but so you can show the court (and your spouse's side) exactly what it was worth and where it came from. Gather account statements from before the marriage, inheritance and gift records, and anything showing the original value of property you're arguing should weigh differently in the division.
On top of that, collect the everyday financial paperwork every divorce needs: recent pay stubs and tax returns, statements for bank, retirement, and investment accounts, mortgage and property records, and a list of debts. New Hampshire family cases require each spouse to file a financial affidavit, so having this organized before you're asked for it saves real stress later.
Keep copies of every letter that arrives from a lawyer, whether it's yours or your spouse's. In a system without a cooling-off period, positions can move quickly once a case is filed, and the letter record is often the clearest evidence of who proposed what and when.
Where minor children are involved, New Hampshire courts generally require parents in a contested case to complete a parenting education program (often called the Child Impact seminar) early in the process. Child support follows the state's child support guidelines, based primarily on both parents' incomes and the parenting schedule. As with property, courts decide parenting arrangements based on the best interests of the child, and a specific, workable parenting plan tends to go further than a vague request for 'reasonable' time.
Legal separation is available in New Hampshire. It is a court proceeding, and in most respects it runs like a divorce: the court can settle support, parenting arrangements and, depending on the case, the division of property, and the resulting order binds both spouses.
What it does not do is end the marriage. People choose it for a range of reasons — health coverage, religious conviction, immigration status, or simply not being ready — and it leaves the door open to reconciling without starting over.
Two consequences follow. Neither spouse can remarry unless they later obtain a divorce, and modifying the order generally takes the court's approval rather than a private agreement between you. If you expect to divorce eventually, ask what converting the separation into a divorce involves here before you start.
New Hampshire does not create common-law marriage. There is no number of years of living together that turns into a marriage here, and none of the divorce machinery on this page applies to a couple who never married — no property division, no spousal support, no residency requirement to satisfy, because there is nothing to dissolve.
What unmarried partners have instead are ordinary civil claims: whatever you agreed between yourselves, in writing or by clear conduct, and claims over property you actually hold jointly. These are argued like any other contract or property dispute rather than as family-law entitlements, and they turn on what can be proved.
One qualification runs the other way and matters. A common-law marriage validly formed in a state that does create them — Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised elsewhere. A couple who met that state's test while living there, and later moved here, are married, and separating means divorcing. Children are unaffected either way: custody and child support are decided on the same basis whether or not the parents married.
1) Build your financial picture first — including premarital and inherited assets, since New Hampshire treats them as part of the estate. 2) Get at least one consultation with a New Hampshire family lawyer before you file; even a single session helps you understand how the all-property rule and equal-division presumption might apply to your situation. 3) Because there's no waiting period, don't assume you'll have a natural pause to get organized after filing — do the preparation now. 4) If you have kids, look up the Circuit Court's parenting education requirement for your county so you're not scrambling to schedule it later. 5) Start a simple log of every letter and deadline the moment the first one arrives; without a mandated cooling-off period, things can move faster than people expect.
Check that you and/or your spouse are domiciled in New Hampshire under RSA 458:5. If you're the only NH resident and your spouse can't be served in-state, you'll need one year of NH domicile before filing.
New Hampshire lets you petition for a legal separation instead of a divorce if you're not ready to end the marriage. If you and your spouse agree on terms, a Joint Petition simplifies the process by skipping formal service.
Fill out the Petition for Divorce (NHJB-2057-F) or Joint Petition for Divorce (NHJB-2058-F), along with the mandatory Personal Data Sheet (NHJB-2077-F). Forms are free on the NH Judicial Branch website.
Submit your paperwork to the Family Division in the county where you or your spouse lives, in person or by e-filing through TurboCourt, and pay the filing fee — which is higher where there are minor children — or file a fee-waiver request.
If you filed an individual Petition, your spouse must be formally served (sheriff or authorized process server). A Joint Petition, signed by both spouses, does not require separate service.
Each spouse files a Financial Affidavit (NHJB-2065-F). If you have minor children, you'll also need a proposed Parenting Plan and Uniform Support Order to address custody, parenting time, and child support.
If you and your spouse agree on all terms and your file is complete, you may qualify for an uncontested final hearing 'on the papers' under Family Division Rule 2.22, avoiding a courtroom appearance. Contested cases proceed to a scheduled hearing.
Once the judge signs the decree, your divorce is final. You can later request certified copies of the decree from the court for name changes, benefits, or other records.
New Hampshire does not recognize common-law marriage for living couples, so unmarried partners don't need a divorce to separate. Custody, parenting time, and child support between unmarried parents are handled through a separate parenting petition in Family Division, not a divorce case.
No. New Hampshire doesn't require a separation period before filing, though you do need to meet the state's residency requirements. Courts generally still take time to move a case through disclosure and, if needed, hearings — confirm current filing requirements with the Circuit Court or a local attorney.
Not automatically. New Hampshire courts can consider nearly all property either spouse owns, including premarital and inherited assets, as part of the marital estate subject to equitable division, though how and when it was acquired is a factor the court weighs. This is a meaningful difference from many other states.
Divorce cases are filed in the Circuit Court's Family Division. Check the New Hampshire Judicial Branch website for the specific location and current forms for your county.
A legal separation in New Hampshire settles much of what a divorce settles — support, parenting and, depending on the case, property — and the order binds both spouses. The difference is that it does not end the marriage, so neither spouse can remarry without later obtaining a divorce. People use it for health coverage, religious reasons, immigration status, or because they are not ready to divorce. Changing the order generally requires the court's approval.
No. New Hampshire does not create common-law marriage, and living together for any length of time gives neither partner property division nor spousal support. Unmarried partners rely instead on agreements between themselves and on claims over jointly held property, argued as ordinary civil matters. One important exception: a common-law marriage validly formed in a state that does create them — such as Colorado, Iowa, Kansas, Montana, Oklahoma, Rhode Island, Texas or Utah — is generally recognised here, so that couple would need a divorce. Custody and child support apply regardless of marriage.
