Quick answer: New Hampshire has three jurisdiction bases, and only one needs a waiting period: a plaintiff who is the only spouse domiciled in the state needs one year of domicile. If both spouses are domiciled, or the defendant is personally served in the state, there is no minimum domicile. The ground is irreconcilable differences, and we found no waiting period after filing.
This New Hampshire divorce timeline calculator applies RSA 458:5 and the ground in RSA 458:7-a. Choose which jurisdiction basis applies and enter your dates: it shows the earliest filing date, nothing more. A real case usually takes longer, because the court must also resolve parenting, support and property.

What does this divorce timeline calculator check?
If both spouses are domiciled in New Hampshire, or the plaintiff is domiciled and the defendant is personally served in the state, the calculator shows that you can file on the date you enter. If only the plaintiff is domiciled, it adds one year to the date domicile began and tells you whether your planned filing date is early. It cannot say how long the court will take. Support and parenting questions that arise during the case are covered by the New Hampshire alimony calculator and the New Hampshire parenting time calculator.
