Everything engaged couples need to know about making a prenuptial agreement valid and enforceable in Pennsylvania — in plain English, reviewed by attorney James Sexton, Esq.
Yes — prenuptial agreements are legal and enforceable in Pennsylvania, which treats them as binding contracts under 23 Pa.C.S. § 3106.
Pennsylvania never adopted the Uniform Premarital Agreement Act; instead it wrote its own rule at 23 Pa.C.S. § 3106, codifying the Pennsylvania Supreme Court's landmark decision in Simeone v. Simeone, 581 A.2d 162 (Pa. 1990). Simeone rejected the old paternalistic approach and held that a prenup is a contract like any other: courts will not review whether the terms were reasonable or whether each side understood their rights, so long as there was no fraud, duress, or misrepresentation and financial disclosure was made. That makes Pennsylvania one of the most enforcement-friendly prenup states in America.
A Pennsylvania prenup is enforceable unless the challenging spouse proves, by clear and convincing evidence, that it was signed involuntarily or without fair and reasonable financial disclosure.
The agreement must be a written document signed by both parties before the marriage. Oral premarital agreements are not enforceable in Pennsylvania.
Because Pennsylvania courts refuse to police fairness, disclosure is the safeguard that matters. Each party must provide fair and reasonable disclosure of their property and financial obligations — or expressly waive further disclosure in writing.
Both parties must sign free of fraud, duress, or misrepresentation. Under § 3106, the challenger carries the burden of proving involuntariness by clear and convincing evidence.
Simeone expressly held that a prenup is binding even if one party had no lawyer. Independent review still helps defeat any later claim of duress or misunderstanding.

|---|---|
| Property division | Equitable distribution |
| Notarization | Recommended (not required by statute) |
| Waiting period | None required — but sign well before the wedding |
| Spousal support | Alimony can be waived — enforced as an ordinary contract term |

Pennsylvania courts almost never overturn a prenup for being unfair — they set one aside only for involuntariness or missing financial disclosure, proven by clear and convincing evidence.
Since Simeone, Pennsylvania judges do not ask whether a prenup was a good deal, whether one spouse got far less than equitable distribution would give, or even whether the signing spouse had a lawyer. The only live questions are contract questions: was the signature voluntary, and was there fair and reasonable disclosure (or a written waiver of it)? That means the practical risk in Pennsylvania isn't a fairness review — it's sloppy disclosure. A prenup with complete, documented asset and debt schedules is about as durable as a contract gets in this state.

No — 23 Pa.C.S. § 3106 does not require notarization, only a written agreement signed by both parties. Notarizing is still smart practice because it proves who signed and when, and it's available as an add-on.
It can, but Pennsylvania is one of the hardest states in which to win a challenge. Under § 3106 the challenger must prove by clear and convincing evidence that the agreement was involuntary or that disclosure wasn't made and wasn't waived — courts will not revisit whether the terms were fair.
In Simeone v. Simeone (1990), the Pennsylvania Supreme Court held that prenups are ordinary contracts: courts won't inquire into the reasonableness of the bargain or whether each party understood their rights. It remains the defining case in Pennsylvania prenup law and is codified at 23 Pa.C.S. § 3106.
No — Simeone specifically held that lack of independent counsel does not void a Pennsylvania prenup. Separate review still strengthens the agreement against duress claims, and Trusted Prenup offers an optional attorney-review add-on.
Yes. Because Pennsylvania treats prenups as contracts, a knowing waiver of alimony or spousal support is enforceable, even if it later looks like a bad deal. Full financial disclosure at signing is what keeps the waiver solid.
Yes — Pennsylvania enforces properly executed prenuptial agreements regardless of how they were drafted. What matters is execution: a written agreement, voluntary signatures, full financial disclosure, and Pennsylvania's signing formalities. The full picture is in are online prenups legally binding.
