About Grafton County
Grafton County is New Hampshire’s largest county by area – a vast stretch from the Connecticut River valley to the western White Mountains, containing one of the Ivy League’s most distinctive campuses and one of the most famous geological losses in New England history.
Dartmouth College (Ivy League, Hanover, enrollment ~7,000) is the eighth-oldest university in the United States (founded 1769) and the northernmost Ivy League institution. Dartmouth’s particular strengths in engineering (the Thayer School of Engineering), business (the Tuck School of Business, consistently ranked among the top MBA programs in the world), and medicine (the Geisel School of Medicine) – combined with its New Hampshire setting and outdoor culture – give it a distinctive character among the Ivies. The Hood Museum of Art and the Hopkins Center for the Arts are outstanding cultural institutions for a campus of Dartmouth’s size.
The Old Man of the Mountain – the famous natural rock formation on Cannon Mountain in Franconia Notch that appeared on the New Hampshire state quarter and was the state’s most recognized symbol – collapsed on May 3, 2003. The five granite ledges that formed the famous profiled face fell into Franconia Notch after thousands of years, ending one of New Hampshire’s most beloved natural features. The profile had been stabilized with cables and epoxy for decades before ultimately succumbing to freeze-thaw cycles. The Franconia Notch State Park preserves the memory site and the surrounding landscape of extraordinary beauty.
Plymouth State University (enrollment ~4,000) anchors the county’s inland communities. The Pemigewasset River and Franconia Notch provide world-class outdoor recreation.

Grafton County was founded in 1769, named for the Duke of Grafton, in western New Hampshire, seated in Haverhill (though Lebanon is the county’s largest city).
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.
