Prenup, Postnup, or Nothing? What Blended Families in PA Should Know Before Remarrying

Remarrying with children from a prior relationship? Pennsylvania state law gives your new spouse a claim to your property if you divorce. Your spouse can also take part of your estate after your death — even when your will leaves everything to your kids.

A prenup or postnup can limit both. The Family Law Team at the LLF Law Firm helps Pennsylvania couples merging households sort out which arrangement fits. Call 888-535-3686 or click here to set up a remarriage planning consultation.

What Does Pennsylvania Law Do If You Sign Nothing?

In a divorce, a court divides marital property under Pennsylvania’s equitable distribution rules. Premarital property generally stays yours, although its growth in value during the marriage is marital. Adding your new spouse to the deed of your house typically makes it entireties property, which passes to them at your death — regardless of your will.

Under 20 Pa.C.S. § 2203, a surviving spouse can elect one-third of a defined pool of your property, even when your will leaves everything to your children. A will signed before the wedding adds risk, since a spouse it leaves out can generally claim the share they’d get with no will. Updating your Pennsylvania estate plan fixes that problem and fixes the elective share at one third but can’t remove the elective share.

What Can a Prenup Change Before the Wedding?

Prenups are hard to undo in Pennsylvania. Under 23 Pa.C.S. § 3106, a spouse has to prove they were pressured into signing or kept in the dark about the other person’s finances, never waived disclosure in writing, and didn’t have independent knowledge of the property. A valid prenup can keep the house you bring into the marriage, along with a parent’s inheritance, out of the marital pot, against contrary arguments having to do with commingling and appreciation. It can also waive alimony.

The elective share waiver matters most to a parent whose will favors the children. It must be in writing, and 20 Pa.C.S. § 2207 allows it before or during the marriage.

Child support can’t be bargained away. Obligations from a first divorce, like a life insurance policy owed to your kids, can be written in as coming from your separate funds.

Why Can’t a Prenup Cover Your 401(k)?

Federal law gives a spouse survivor rights in most employer pensions and 401(k) plans. Your future spouse can sign a prenup promising to give those rights up, and the plan will still ignore it because the person signing wasn’t your spouse yet, unless the prenup requires a post-marriage waiver. A valid waiver must come after the wedding. 29 U.S.C. § 1055(c) also requires a notary or plan representative to witness the signature.

IRAs and life insurance policies run on beneficiary forms instead. Whoever is listed gets paid, and an outdated designation can send money somewhere your agreement never intended.

What If You’re Already Married?

Wedding planning eats up time, and plenty of couples never get to a prenup. A postnuptial agreement picks that conversation back up later. Pennsylvania judges review it like any contract and expect full financial disclosure from both of you. Your spouse can sign the 401(k) waiver then, too, though they may resist giving up rights they already hold.

How Do You Weigh Your Options?

Some couples review Pennsylvania’s default rules and decide they work fine. Others want specific assets protected in writing. When they sign affects which protections hold.
