How we match your Portsmouth family law case

When you submit a Portsmouth family law matter, we route it through a national network of independent partner firms and put it in front of the one that fits best — based on the kind of case it is, what it is likely to involve, where it has to be handled, and who has capacity to take it on now.

Case type

A family law matter needs someone who handles family law work day to day, not a generalist. Practice area is the first filter.

Size and complexity

Some firms are built for catastrophic injury and multi-party litigation; others resolve straightforward claims quickly. We weigh what your matter is likely to involve against how each firm actually works.

Jurisdiction and licensing

Your matter is decided under New Hampshire law, so it goes to an attorney licensed in New Hampshire who regularly appears where your case would be heard.

Capacity and fit

Availability, conflicts of interest and language all matter. If the best-fit firm cannot take your case, we route it to the next one that can — or tell you plainly when no one in the network is the right answer.

Every partner reviews your case for free. Injury and workers’ compensation matters are handled on contingency — no fee unless you win. Other matters are quoted upfront, before you commit to anything.

It goes to the family division of the New Hampshire Circuit Court serving Rockingham County, which handles divorce, parenting plans, and support together. Filing in the wrong division causes delay. An attorney will confirm the correct location and what has to be filed first.

That depends on residency and, for children, which state counts as the child's home state. New Hampshire and Maine can each have a role, and the answer shapes both the parenting plan and support. An attorney will evaluate residency before anything is filed to avoid a jurisdictional fight.

It varies widely with how much the parties agree on, whether financial disclosure is complete, and the court's schedule. Uncontested matters resolve far faster than contested parenting disputes. New Hampshire also sets procedural deadlines that vary, so have an attorney confirm the ones that apply to you.

Uncontested divorces in New Hampshire typically finalize 60–120 days after filing. Contested cases generally take 9–18 months. New Hampshire has no mandatory waiting period from filing to decree.
