New Castle County has older Wilmington rowhouses and multifamily buildings, student rentals around Newark, and newer subdivisions in Middletown and Bear. An older city house can come with lead paint and other repair questions, which matters when heirs live far away and nobody is watching it. This is general information, not legal or tax advice. An estate attorney should review your file.
The Register of Wills guide used by Sussex County says anyone holding a possible will must deliver it within ten days of learning of the death, to the Register in the county where the person lived. For a Wilmington or Newark resident, that is the New Castle County office. Order certified death certificates so you have enough for the Register, banks and the title company.
New Castle County says to call (302) 395-7800 to schedule. The same line handles requests for the Middletown or Hockessin evening hours, which helps heirs who work during the day. Regular in-person hours end at 3:30 p.m. Monday through Thursday and at 3:00 p.m. on Friday.
The petition depends on whether there is a will and a qualified executor. A named executor asks for Letters Testamentary. Otherwise the applicant seeks Letters of Administration, with the Will Annexed if there is a will. With no will, the guide lists spouse, children, parents, then siblings. Families with several children should agree on one or two people and have the others renounce in writing.
House Bill 333 raised the small estate limit from $30,000 to $50,000 for deaths on or after June 10, 2026. That shortcut covers solely owned personal property. A house in the decedent's own name generally means the estate must be opened, per the Register booklet, so do not plan on an affidavit for a Wilmington rowhouse.
The personal representative files an inventory within three months of opening the estate. Creditors have eight months from the date of death to file claims. The accounting is due within a year of opening. Missing these dates can slow a sale and complicate the final distribution to heirs.
Delaware title passes to the beneficiaries at death, according to the booklet, but a personal representative must sell if the estate cannot pay its bills any other way. Before any sale, walk the house with a trusted contractor or agent so you know what the buyer will see. Older city houses often need work, and the heirs will want that number before they pick a route.

Official pageHeirs of a New Castle County house have a few honest paths. An agent listing can reach the widest pool of buyers, and it can work well for a Middletown or Bear home in move-in shape. A rowhouse with deferred repairs may need cleanout, inspection fixes and a longer carrying period before a retail buyer steps in. Holding the property is also possible, but heirs pay insurance, taxes and upkeep while they wait.
Kaizen buys as-is for cash. We make an offer within 24 hours, charge no agent commission, require no repairs, and can close in 14 to 30 days or on your date. That can fit heirs who live out of state and cannot manage a cleanout. The estate must still show who can sign for the property, so check with your attorney. Call 267-329-0084.

The county lists evening hours at the Appoquinimink Public Library, 204 E. Main Street, Middletown, on the first Wednesday of each month from 4:00 p.m. to 5:00 p.m., and mentions Hockessin evening hours. Call (302) 395-7800 and say which one you want.
The Delaware estate tax chapter is marked repealed, effective January 1, 2018, and the inheritance tax ended for deaths on or after January 1, 1999, according to the Sussex County Register's booklet. Federal tax and income tax questions on a later sale are separate, so talk to a tax professional.
If the house was in the decedent's name alone, the booklet says an estate must be opened. If it was held jointly with right of survivorship, a separate affidavit may apply. An attorney can tell you which fits.
Kaizen makes as-is cash offers and can close in 14 to 30 days or on your date, with no repairs and no agent commission. Heirs should confirm authority to sell with the Register of Wills or an attorney first. Call 267-329-0084.
