The Short Answer

In Pennsylvania, one heir generally cannot bind your ownership interest in estate real estate with a sale contract if you did not sign it. However, depending on whether the property is still being administered through probate (and who has authority as the personal representative), a contract signed by the personal representative may be enforceable even without every heir’s signature.

What Pennsylvania Law Says

Who can sell estate real estate—and whether your signature is required—often turns on (1) whether the property is still part of the probate estate under the control of the personal representative (executor/administrator), and (2) whether the property was specifically devised in a will or is being sold as part of administration.

The Statute

The primary law governing this issue is 20 Pa.C.S. § 3351 (Power to sell).

This statute establishes that, unless the will provides otherwise, the personal representative may sell estate property (including certain real property), and that selling specifically devised real estate generally requires the joinder of the specific devisee.

Related authority also matters in many disputes about “who controls the property during probate.” Pennsylvania law provides that a personal representative generally has the right to take possession of and administer the decedent’s real and personal estate during administration. See 20 Pa.C.S. § 3311.

If a sale needs court protection or the personal representative’s authority is disputed/limited, the personal representative can seek an Orphans’ Court order to sell (including to give the transaction the effect of a judicial sale). See 20 Pa.C.S. § 3353.

Why You Should Speak with an Attorney

Even when you are clearly an heir, disputes about a “contract to sell” can escalate quickly—especially if a buyer, realtor, or title company is involved. While the statutes provide the general rules, applying them to your situation is rarely simple. Legal outcomes often depend on:

• Authority vs. ownership: If the personal representative signed (or later seeks court approval), the deal may be treated very differently than if an heir signed on their own without authority. Statutory authority to sell can come from the Probate Code and/or the will. See 20 Pa.C.S. § 3351 and 20 Pa.C.S. § 3353.
• Burden of proof and paperwork: The key documents (deed history, will language, Letters Testamentary/Administration, and the actual agreement of sale) determine whether the signer had power to bind the estate or only attempted to sell an individual interest.
• Exceptions and court involvement: If the property was specifically devised, joinder issues can arise under the statute; if the estate needs liquidity to pay debts/expenses, the personal representative may pursue a court-backed sale; and if co-owners cannot agree after distribution, a partition-style dispute may be on the table.

Trying to handle this alone can lead to a signed contract being used as leverage against you, unnecessary litigation, or a cloud on title that delays any legitimate sale. A probate attorney can quickly assess whether the contract is enforceable, who had authority to sign, and what relief is available in Orphans’ Court if needed.
