Simeone v. Simeone

Pennsylvania Supreme Court rejected the older "fairness" standard for prenups and adopted pure contract-law principles, making Pennsylvania one of the most enforcement-friendly jurisdictions in the country.

Why this case matters

Simeone changed Pennsylvania prenup law overnight and remains the controlling authority today. The case represents one pole of the American jurisprudential spectrum: prenups as ordinary contracts, with minimal special protection. For Pennsylvania readers, it explains why your prenup is likely to be enforced even if you didn't have your own attorney — and why making sure the disclosure is right matters more than anything else.

The facts

Catherine and Frederick Simeone signed a prenup the night before their 1975 wedding. Catherine, a 23-year-old unemployed nurse, signed in front of an attorney retained by Frederick — no independent counsel of her own. Frederick was a 39-year-old neurosurgeon. The prenup limited Catherine's spousal support to $200 per week, capped at $25,000 total. They divorced in the 1980s; Catherine challenged the agreement, arguing that prenups should be subject to heightened "reasonableness" review and that the limit was unfair given Frederick's wealth.

The holding

The Pennsylvania Supreme Court refused to apply a heightened reasonableness test. The court explicitly overruled prior Pennsylvania case law that had treated prenups as requiring special scrutiny because of the inherent inequality between parties. Going forward, prenups in Pennsylvania would be reviewed under ordinary contract-law principles: enforceable unless tainted by fraud, duress, or misrepresentation. The court reasoned that paternalistic protection of one spouse was incompatible with modern equality between sexes.

What it means for you

• Pennsylvania treats prenups like ordinary contracts — no heightened fairness review.
• The absence of independent counsel is not, by itself, grounds to invalidate.
• A prenup that produces an unfair outcome is still enforceable if it was free of fraud, duress, or misrepresentation when signed.
• Full financial disclosure is the central procedural requirement; everything else is treated as ordinary contract law.
• This is the most pro-enforcement framework among major US jurisdictions.
