A Pennsylvania prenuptial agreement is a contract that two people sign before they marry. It sets the rules for how property, debt, and spousal support will be handled if the marriage ends in divorce or death.
Not legal advice. This article is general information only. Prenup laws differ by state and change over time. Consult a licensed attorney in your state before acting on anything here.
Pennsylvania treats these agreements as ordinary contracts. The state’s courts enforce them strictly, which makes the wording and the financial disclosure behind the document especially important.
This guide explains how prenups work under Pennsylvania law, what they can and cannot cover, how they must be signed, and what they typically cost.
Will Pennsylvania Courts Enforce a Prenup?
Yes. Prenuptial agreements are legal and enforceable in Pennsylvania when they meet the state’s requirements for a valid contract.
The framework comes from two places: the case law set by the Pennsylvania Supreme Court in Simeone v. Simeone (1990), and the premarital agreement statute at 23 Pa.C.S. § 3106. Together they give Pennsylvania one of the more contract-friendly approaches in the country.
The Simeone Standard
In Simeone v. Simeone, 525 Pa. 392, 581 A.2d 162 (1990), the court held that prenuptial agreements are governed by the same rules as other contracts. It rejected the older idea that a court should review the deal for whether the terms were reasonable or fair to one spouse.
This is the part that surprises many people. Pennsylvania does not apply a “second look” at fairness when the marriage ends. If the disclosure was full and fair when the parties signed, a court will enforce the agreement even if the terms turned out to be one-sided or lopsided.
The court reasoned that adults are free to make their own bargains, and that a signed contract should not be undone later just because one side later regrets it.
Who Bears the Burden
Under 23 Pa.C.S. § 3106, the burden falls on the spouse who wants to throw out the agreement. That person must prove their case by clear and convincing evidence, which is a high standard.
An agreement can be set aside only if the challenger shows either that they did not sign it voluntarily, or that they were not given a fair and reasonable disclosure of the other party’s property and financial obligations before signing.
What a Pennsylvania Prenup Can Cover
A prenup lets a couple decide in advance how financial matters will be handled. The table below shows common topics that Pennsylvania agreements address.
| Topic | What it can do |
|---|---|
| Separate property | Identify assets each person keeps as their own, including assets brought into the marriage |
| Marital property | Set how property acquired during the marriage is classified and divided |
| Debt | Assign responsibility for existing and future debts |
| Spousal support and alimony | Set, limit, or waive support, subject to limits below |
| Business interests | Protect a company or professional practice from division |
| Inheritance and estate rights | Define what a spouse receives at death and protect children from a prior relationship |
| Life insurance | Require a policy or name a beneficiary |
What a Pennsylvania Prenup Cannot Do
Some terms are off limits no matter how the contract is written. A Pennsylvania court will ignore or strike these provisions.
- Set or limit child support. That right belongs to the child, not the parents, so it cannot be bargained away.
- Decide child custody or visitation. Courts decide these based on the child’s best interest at the time of the dispute.
- Include anything illegal or that encourages divorce.
- Cover personal, non-financial demands, such as chores, weight, or how often the couple sees in-laws. Courts will not enforce these.
How a Pennsylvania Prenup Must Be Signed
Pennsylvania keeps the signing rules simple. The formalities matter because a defect can give the other side an opening to challenge the document.
Writing and Signatures
The agreement must be in writing and signed by both parties. Verbal promises between spouses do not count and cannot be enforced as a prenup.
Witnesses and Notarization
Pennsylvania law does not require witnesses or a notary for the agreement to be valid. Even so, most couples have the document notarized.
Notarization adds proof that the signatures are genuine and that each person signed voluntarily. That extra record helps if the agreement is ever questioned in court.
Timing and Voluntariness
There is no fixed waiting period in the statute, but timing still matters. Signing well before the wedding, rather than the night before, reduces any later claim of pressure or duress.
Can a Pennsylvania Prenup Waive Alimony?
A Pennsylvania prenup can set, cap, or fully waive spousal support and alimony. The couple can agree on an amount, a payment schedule, and a duration.
Because the state follows contract rules, a support waiver is generally enforced even if it leaves one spouse with little. As long as the disclosure was full and fair at signing, the court will honor the terms.
This is one of the strongest reasons people in Pennsylvania use a prenup. The agreement gives both partners certainty about support instead of leaving it to a judge later.
The Role of Full Disclosure in Pennsylvania
Disclosure is the heart of an enforceable Pennsylvania prenup. Each person must give the other a fair and reasonable account of their property, income, and debts before signing.
Under 23 Pa.C.S. § 3106, a missing or misleading disclosure is one of the few grounds to void an agreement. If a spouse hid major assets or debts, the other can ask a court to set the contract aside.
The practical fix is a written schedule of assets and liabilities attached to the agreement. A party can waive disclosure in writing, but a complete attached statement is the safer route.
What Happens Without a Prenup in Pennsylvania
Without a prenup, state default rules apply if the marriage ends. Pennsylvania is an equitable distribution state, not a community property state.
Equitable distribution does not mean a 50-50 split. A judge divides marital property in a way the court considers fair, based on factors such as income, length of the marriage, and each spouse’s contributions.
That means the outcome is decided by a court, not by the couple. A prenup replaces that uncertainty with terms the two people chose themselves.
Common Reasons Pennsylvania Prenups Fail
Most agreements that get thrown out share a small set of problems. Avoiding these keeps a prenup on solid ground.
- Incomplete or false financial disclosure, which is the leading cause of challenges.
- Signs of duress, such as presenting the document hours before the ceremony.
- Trying to control child support or custody, which courts will not enforce.
- Sloppy drafting, vague terms, or missing signatures.
- Pressure that prevented one party from reading or understanding the agreement.
How Much Does a Prenup Cost in Pennsylvania?
Cost depends on how complex your finances are and whether each partner hires a separate lawyer. The table below shows common ranges.
| Option | Typical cost |
|---|---|
| Simple attorney-drafted agreement | $1,500 to $5,000 per couple |
| Complex agreement with separate counsel | $2,000 to $7,000 per person |
| Online platform | A few hundred dollars, flat |
Online services have made prenups far more affordable. HelloPrenup is one option that walks both partners through a Pennsylvania-specific questionnaire and produces a draft you can each review.
Many couples use an online platform to build the first draft, then have a Pennsylvania attorney review it. That approach controls cost while keeping a professional check on the terms.
How to Create a Pennsylvania Prenup, Step by Step
The process is straightforward when you give yourselves enough time before the wedding.
- Start early, ideally several months before the ceremony.
- Have an honest conversation with your partner about goals and expectations.
- Gather a full list of each person’s assets, income, and debts.
- Exchange written financial disclosures and attach them to the agreement.
- Draft the terms, using an attorney or a Pennsylvania-specific online platform.
- Let each partner review the draft, ideally with independent legal advice.
- Sign the final document in writing, and have it notarized for added proof.
Final Thoughts on a Pennsylvania Prenup
Pennsylvania enforces prenuptial agreements firmly. Thanks to Simeone v. Simeone, a signed agreement backed by full disclosure will usually hold up, even if the terms favor one side.
That strength cuts both ways. It rewards couples who disclose honestly and sign without pressure, and it punishes shortcuts like hidden assets or last-minute signing.
Take your time, be transparent about your finances, and put everything in writing. A clear agreement gives both partners a shared understanding before the marriage begins.
