Pennsylvania Prenup Laws: Guide for Engaged Couples

Getting married in Pennsylvania? A prenuptial agreement lets you set clear expectations about property, debt, and (where allowed) support—so you’re not relying only on default state rules.

Key points

  • Prenups are recognized if they’re voluntary, in writing, and signed by both partners.
  • Enforced if entered voluntarily and with full disclosure or waiver. No requirement for fairness review at divorce — only at the time of signing.
  • Pennsylvania prenups must be in writing and signed by both parties before marriage. Notarization is not required but recommended.

Are prenups legal in Pennsylvania?

Pennsylvania prenups must be in writing and signed by both parties before marriage. Notarization is not required but recommended. Full and fair financial disclosure is expected unless explicitly waived in writing. Independent counsel is not mandatory but highly advisable.

What makes a Pennsylvania prenup enforceable?

Enforced if entered voluntarily and with full disclosure or waiver. No requirement for fairness review at divorce — only at the time of signing. Fraud, duress, or misrepresentation can void the agreement.

What you can—and can’t—include

May waive property rights, inheritance, and alimony. Child-related provisions are unenforceable.

Simple process

Provide detailed written disclosures, sign well in advance of the wedding, and consider notarization and separate counsel.
