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.
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.
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.
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.
