About Cumberland County
Cumberland County is Maine’s most populous county and home to Portland – a city that has undergone one of the most celebrated urban transformations of any small American city in the 21st century.
Portland (the county seat, population ~70,000) has been named one of America’s best food cities by virtually every major food publication for over a decade. The Old Port district – restored 19th-century brick commercial buildings along the working waterfront – houses a density of exceptional restaurants, craft breweries (Allagash Brewing Company, founded 1995, is the region’s most celebrated craft brewer), and independent shops that rivals cities many times Portland’s size. The Portland Press Herald reported in 2024 that Portland has more restaurants per capita than any other city in the United States. James Beard Award nominees and winners from Portland have included some of the most talked-about chefs in the country.
Casco Bay – the island-studded bay sheltering Portland’s harbor – includes the Calendar Islands (so named because legend holds there is one for each day of the year), with Peaks Island, Great Diamond Island, Little Diamond Island, Cliff Island, Chebeague Island, and Long Island all accessible by the Casco Bay Lines ferry. These islands are year-round communities with permanent populations who commute by ferry to Portland for work and services.
Bowdoin College in Brunswick (enrollment ~1,800) is one of New England’s most selective liberal arts colleges and one of America’s oldest (founded 1794). Bowdoin alumni include Henry Wadsworth Longfellow, Nathaniel Hawthorne, Franklin Pierce (14th US President), and Robert Peary (first to reach the North Pole). The Bowdoin College Museum of Art and Peary-MacMillan Arctic Museum are outstanding institutional collections.
Freeport – 18 miles north of Portland – is home to L.L. Bean‘s flagship store (open 24 hours a day, 365 days a year, it has never locked its doors since 1951) and a major outlet shopping corridor. L.L. Bean’s presence transformed Freeport from a quiet mill town into one of Maine’s most visited commercial destinations.
Cumberland County’s real estate market has been the fastest-appreciating in New England for most of the past decade, driven by remote work migration, population growth, and Portland’s extraordinary quality of life appeal.
County government is limited – courts and Registry of Deeds are county functions; all services are otherwise municipal or state.

Maine requires municipalities to assess property at 100% of just value (market value). Each of Cumberland County’s 28 municipalities has its own assessors. Assessment accuracy and equalization ratio monitoring is conducted by the Maine Revenue Services Property Tax Division.
Portland’s extraordinary appreciation: Portland’s real estate has appreciated so dramatically that homeowners who purchased before 2015 typically have assessed values substantially below current market – favorable protection. Recent buyers are assessed at or near purchase price. The March 1 abatement deadline is critical for those who believe their assessed value exceeds current market.
The abatement process:
File an abatement application with your local board of assessors by March 1 of the tax year. The assessors must respond within 60 days. If denied, appeal to the Maine Board of Assessment Review (state administrative body) or to the Cumberland County Superior Court within 60 days of the denial.
Maine estate tax: Above $6.41 million (2025 – adjusted annually for inflation) at rates up to 12%. No Maine inheritance tax. Federal estate tax applies above approximately $13.9 million (2025).
OWNWELL CTA: Cumberland County abatement deadline March 1. Portland’s extraordinary appreciation means recent buyers should verify assessed values. Casco Bay island properties have unique valuation considerations. Maine estate tax at $6.41M – below federal threshold. Ownwell manages the abatement with no upfront cost.

Cumberland County is Maine’s most populous county, seated in Portland, the state’s largest city. Unlike most states, Maine has a separate elected Probate Court in every county, distinct from the District and Superior Courts that handle other civil matters.
Step 1: figure out which path applies
Maine adopted the Uniform Probate Code effective July 1, 2019 (Title 18-C), replacing the prior Title 18-A. Maine is one of fewer than 20 UPC states, so its informal/formal probate tracks and terminology follow the uniform model used elsewhere.
Collection of Personal Property by Affidavit (Small Estate Affidavit) – under 18-C §3-1201, available when the estate’s personal property value is below a threshold that’s adjusted annually for inflation (historically around $40,000-$50,000 and rising). No probate case or personal representative appointment is required; a successor can present a sworn affidavit directly to banks or others holding the decedent’s property. Each county’s Probate Court publishes the current year’s threshold on its website.
Informal Probate – the path most Maine estates use. Available when the will (if any) is uncontested, the estate is straightforward, and no interested party objects. A Probate Registrar (not a judge) reviews and approves the application without a hearing.
Formal Probate – required when a will is contested, the personal representative appointment is disputed, or supervised administration is requested. These matters go before the elected Judge of Probate at a hearing.
Step 2: filing for probate
For informal probate with a will, file Form DE-201(I) (Application for Informal Probate of Will or Appointment of Personal Representative); for informal intestate proceedings (no will), file Form DE-101(I) – both with the Probate Court in the county where the decedent was domiciled. Applications cannot be filed earlier than 5 days after death.
In informal probate, the Register reviews the application and, if in order, issues a Statement of Informal Probate and Letters appointing the personal representative – no hearing required.
The personal representative must file an inventory of estate assets with the court within 3 months of appointment.
Notice to creditors must be published once a week for 2 successive weeks in a newspaper of general circulation in the county, and the personal representative must mail written notice to known creditors within 4 months of appointment (18-C §3-801). Creditors generally have up to the statute’s claims period to file, with a 3-year outer statute of limitations.
The personal representative pays valid debts and taxes in priority order, then distributes remaining assets and files a final accounting to close the estate.
What it costs
Filing fees are based on estate value and range roughly from $40 to over $1,200, set by each county’s fee schedule.
Publication costs for the creditor notice typically run $150-$300.
Maine does not set a statutory percentage fee for attorneys or personal representatives; fees must be “reasonable” based on the time and complexity of the work involved.
While not legally required, hiring an attorney is commonly recommended, especially for formal probate or if the estate is at all complex.
