About Strafford County
Strafford County is the gateway between New Hampshire’s seacoast and its inland regions – containing the state’s oldest city, its flagship university, and the extraordinary ecological resource of Great Bay.
Dover (the county seat, population ~32,000) was founded in 1623 and is the oldest city in New Hampshire and one of the oldest in the United States. Dover’s downtown has undergone significant revitalization – the restored Cocheco River mills along Henry Law Avenue, the Children’s Museum of New Hampshire, and a growing restaurant and arts scene make it one of the Seacoast’s most dynamic communities.
Durham (population ~14,000) is home to the University of New Hampshire (UNH, enrollment ~15,000) – New Hampshire’s flagship land-grant public research university, with particular strengths in marine science (the UNH Jackson Estuarine Laboratory on Great Bay), engineering, and business. UNH’s presence makes Durham one of the most college-influenced communities in New Hampshire, with enrollment cycles driving the real estate and rental markets.
Great Bay – a tidal estuary connecting the Piscataqua, Oyster, Lamprey, Squamscott, and Winnicut rivers – is one of the most significant estuarine ecosystems in New England, a critical habitat for Atlantic sturgeon, wild oysters, and migratory waterfowl. The Great Bay National Wildlife Refuge protects key portions.
Farmington and Rochester (Strafford County’s largest city at 32,000) provide more affordable housing options relative to the seacoast, drawing working families from Portsmouth and Dover.

Strafford County is in southeastern New Hampshire, seated in Dover.
Step 1: figure out which path applies
New Hampshire has NOT adopted the Uniform Probate Code. Probate is handled by the Probate Division of the Circuit Court in the county where the decedent resided – each of New Hampshire’s 10 counties has its own Probate Division. New Hampshire does not use a fixed-dollar “small estate affidavit” the way most states do; instead it offers two main shortcuts based on circumstances rather than estate value alone.
Voluntary Administration – available for estates consisting entirely of personal property valued at $10,000 or less.
Waiver of Full Administration (RSA 553:32) – available based on WHO inherits and administers, not a dollar threshold. It can apply when a sole beneficiary or sole heir serves as administrator, when all beneficiaries or heirs serve together, when all beneficiaries or heirs assent to the administrator, or when the court finds a waiver appropriate. A waiver eliminates the requirement to file an inventory, obtain a bond, or file a formal accounting – the administration is completed by filing an affidavit of administration, due six months to one year after appointment.
Summary Administration (RSA 553:33) – available by court order for an estate with a gross value (after deducting encumbrances) of $300,000 or less, if the court finds it advisable given the nature, character, and obligations of the estate.
Full (Formal) Administration – required for larger, more complex, or contested estates.
Step 2: filing for administration
File a Petition for Estate Administration (Form NHJB-2145-P) with the Probate Division in the county where the decedent resided, to admit the will (if any) and appoint a personal representative.
The court issues Letters Testamentary (if there’s a will) or Letters of Administration (if intestate).
The personal representative publishes notice to creditors. Creditors have 6 months from the date of first published notice to file claims – no final distribution is permitted before this period ends.
Unless a waiver of full administration applies, the personal representative files an inventory of the estate’s assets and, later, an accounting.
After debts, taxes, and expenses are paid and the creditor period expires, the personal representative distributes the remaining assets and closes the estate.
What it costs
The filing fee for a standard Petition for Estate Administration is generally around $150, plus an additional $55 publication fee if notice must be published.
Executor/administrator compensation is “reasonable” and determined by the court rather than set by a fixed statutory percentage schedule.
New Hampshire has no state estate tax and no state inheritance tax. Only the federal estate tax could apply, and only to very large estates.
