How Pennsylvania classifies marital property
Pennsylvania uses equitable distribution to divide marital property at divorce. Courts consider each spouse’s income, contributions to the marriage, length of the marriage, and other factors — but “equitable” doesn’t mean equal. A prenup lets you define your own division rules in advance, removing uncertainty about how a court might split your assets.
Understanding Pennsylvania's equitable distribution system is critical because a prenup is essentially your opportunity to override these default rules. Without one, a judge decides what's "fair" based on subjective factors like each spouse's income, contributions, and future needs.
The legal framework: 23 Pa. C.S. § 3104
Prenuptial agreements in Pennsylvania are governed by 23 Pa. C.S. § 3104. While Pennsylvania has not adopted the Uniform Premarital Agreement Act (UPAA), the state's statutes provide clear requirements for valid prenuptial agreements.
Signing requirements in Pennsylvania
Pennsylvania has specific requirements that must be met for a prenuptial agreement to be valid. Missing any of these can give a court grounds to throw out the entire agreement.
- **Written agreement** — Must be in writing — verbal prenups are not valid
- **Signed by both parties** — Both parties must sign voluntarily before the wedding
- **Notarization recommended** — Not legally required but strongly advised for court enforceability
- **Independent legal counsel (strongly recommended)** — Pennsylvania courts heavily weigh whether each party had their own attorney — strongly affects enforceability
- **Full financial disclosure** — Both parties must disclose all assets, debts, and income — incomplete disclosure is the #1 reason prenups are invalidated
- **State-specific requirement** — Courts strongly consider whether each party had independent counsel (Simeone v. Simeone, 1990)
Spousal support in a Pennsylvania prenup
Spousal support waivers are generally enforceable in Pennsylvania prenups, provided the agreement meets all other legal requirements — voluntary execution, full financial disclosure, and terms that are not unconscionable. Note: Pennsylvania upholds prenup terms even if outcome is uneven, provided agreement was voluntary and both parties had access to counsel.
Key case law: Simeone v. Simeone (1990)
The Pennsylvania Supreme Court held that prenups should be treated like ordinary contracts. Courts will uphold the terms even if the financial outcome is uneven, provided the agreement was voluntary and each party had access to counsel.
What this means for your prenup: Clause ensures Pennsylvania prenups meet voluntariness standards and that each party has access to independent counsel — the key enforcement factor under Simeone.
Sunset clauses and special provisions
Pennsylvania courts will enforce sunset clauses — provisions that cause the prenup to expire after a set number of years. If you want the agreement to remain in effect indefinitely, make sure to exclude a sunset clause or explicitly state that the agreement has no expiration.
Build your Pennsylvania prenup on Clause
Clause generates a legally valid, Pennsylvania-specific prenuptial agreement starting at $549 — a fraction of the $5,000–$20,000 that traditional attorney-drafted prenups cost in Pennsylvania. The Agreement Builder automatically handles Pennsylvania's signing requirements, and financial disclosure obligations. Attorney review and online notarization are available as add-ons.
