PARKS & RECREATION
Key Assets: Putnam County lies directly across the Hudson River from the United States Military Academy at West Point and holds genuine, deep Revolutionary War significance – Constitution Island, in the Hudson River within Putnam County’s Cold Spring/Garrison area, is the site of the earliest Revolutionary War fortifications in the Hudson Valley, briefly captured by the British in 1777 before American forces retook it in 1778 and made it an integral part of Fortress West Point; George Washington considered the defense of the Hudson Highlands at West Point “the key of America” and personally spent about a third of the entire war in or near this stretch of the river; the “Great Chain,” a massive iron chain stretched across the Hudson to block British naval passage, was famously anchored on the Putnam County shore, with surviving remnants displayed today on the Great Lawn at Boscobel House and Gardens in Garrison, a neoclassical mansion built 1804–1808 with panoramic Hudson River views and now home to the Hudson Valley Shakespeare Festival; the county is named for Israel Putnam, a Revolutionary War general
Notes: Putnam County’s genuine role in Revolutionary War Hudson Valley defense – directly across from West Point and home to remnants of the Great Chain – makes it one of the more historically significant counties found anywhere in this project.

About Putnam County
Putnam County is a Hudson Valley county and the 581st most populous in the United States, covering 232 square miles of rugged terrain between the Hudson River and Connecticut border.
Carmel (the county seat, an unincorporated community in the Town of Carmel, population ~35,000 town) is Putnam County’s largest and most populous town – a suburban community centered on Lake Mahopac whose residential character is defined by commuter access to New York City via I-84 and the proximity of Metro-North’s Harlem Line.
Brewster (in the town of Southeast) is Putnam County’s primary commuter rail hub – the Brewster North Metro-North station provides direct service to Grand Central Terminal, making it the county’s transportation anchor for New York City commuters.
Clarence Fahnestock State Park – 14,000 acres of forests, lakes, and wetlands in the county’s central section – provides extraordinary outdoor recreation access within 60 miles of Manhattan. The Appalachian Trail passes through the county’s Hudson Highlands terrain, offering one of the trail’s most dramatic sections in its approach to the Hudson River crossing at the Bear Mountain Bridge.
Putnam County’s small geographic size – just 232 square miles – and relatively small population make it one of the more intimate Hudson Valley counties, with a character shaped more by its rugged terrain and commuter demographics than by any urban center.

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Putnam County Surrogate’s Court Historic Courthouse, 44 Gleneida Avenue, Carmel, NY 10512 (845) 208-7860 Putnam County is in New York’s Hudson Valley, seated in Carmel.
Step 1: figure out which path applies
New York probate and estate administration is governed by the Surrogate’s Court Procedure Act (SCPA) and handled by the Surrogate’s Court in the county where the decedent was domiciled. New York has 62 counties, each with its own Surrogate’s Court.
Voluntary Administration / Small Estate Affidavit (SCPA Article 13) – available when the decedent’s PERSONAL property (not real property) has a gross value of $50,000 or less, excluding certain property automatically set aside for a surviving spouse or children under 21 (EPTL 5-3.1). Owning real property does NOT disqualify an estate from this process – only the personal property counts toward the $50,000 cap. The filing fee is just $1.00.
Probate – required when there’s a valid will and the estate exceeds the small-estate threshold or involves real property.
Administration – required when the decedent died intestate (no will); the Surrogate’s Court appoints an administrator following the statutory priority order under SCPA 1001.
Step 2: filing for probate or administration
File the will (if any) with the Surrogate’s Court in the county where the decedent was domiciled, along with a probate or administration petition.
The court issues Letters Testamentary (with a will) or Letters of Administration (without a will) to the appointed fiduciary.
The fiduciary notifies creditors and beneficiaries and inventories the estate’s assets.
Debts, expenses, and any required New York State Estate Tax are paid.
The fiduciary distributes the remaining assets according to the will or New York’s intestacy law and files a final accounting to close the estate.
What it costs
Voluntary Administration filing fee: $1.00.
Full probate/administration filing fees scale with the gross estate value in Putnam County: fees range up to $1,250 for estates of $500,000 and over. Additional fees may apply for certified documents or contested proceedings.
UNIQUE TO NEW YORK: New York imposes its own separate state ESTATE TAX. For 2026, the New York basic exclusion amount is $7,350,000 – estates at or below that owe no state estate tax. New York has an unusual “cliff”: if the estate’s value exceeds the exclusion by more than 5% (over $7,717,500 in 2026), the ENTIRE estate becomes taxable from the first dollar. No portability between spouses. Rates range from about 3.06% to 16%.
New York has no separate state inheritance tax.
