Prenups for People Who Didn't Get Prenups: Your Postnup Game Plan

Let me guess: when you got married, you were so in love that talking about prenups felt like planning for failure. You probably thought prenups were for celebrities, billionaires, or cynical people who didn't really believe in marriage. Fast forward a few years, and now you're lying awake at night wondering what would happen to your business, your inheritance, or your retirement accounts if things went south.

Welcome to the "I wish I had gotten a prenup" club. Membership is huge, but here's the good news: you can still protect yourself with something called a postnuptial agreement. It's like a prenup's younger, wiser sibling who learned from everyone else's mistakes.

What Exactly Is a Postnup (And Why You Need One)

A postnuptial agreement is basically a prenup that you create after you're already married. It lets you and your spouse decide how your assets, debts, and other financial matters will be handled if you divorce, instead of leaving those decisions to state law and divorce judges.

Think of it as a financial insurance policy for your marriage. You hope you never need it, but if you do, you'll be glad you have it.

Here's what a postnup can do for you:

  • Protect assets you brought into the marriage or acquired during it

  • Keep your business separate from marital property

  • Define how inheritances or gifts from family will be treated

  • Establish terms for spousal support

  • Protect you from your spouse's debts

  • Provide clarity about financial responsibilities during marriage

Who Actually Needs a Postnup

Postnups aren't just for people who are having marriage problems. In fact, the best time to create one is when your marriage is strong and you can have rational conversations about money.

You might want a postnup if:

  • You've started a business or your business has grown significantly since marriage

  • You've received or expect to receive a substantial inheritance

  • One of you has gone back to school or changed careers

  • You've acquired valuable assets (real estate, investments, collectibles)

  • One spouse has significantly more debt than the other

  • You're planning to support aging parents financially

  • You want to protect assets for children from previous relationships

The "But We're Happily Married" Objection

I hear this all the time: "We don't need a postnup because we're happy." That's like saying you don't need car insurance because you're a good driver. The point isn't that you're planning to get divorced – it's that you're planning to protect your financial interests regardless of what happens. 

AND DO IT NOW! WHILE YOU’RE BOTH STILL REASONABLE. 

Happy marriages end in divorce all the time. People change, circumstances change, and sometimes love isn't enough. A postnup doesn't mean you're expecting divorce; it means you're being realistic about the fact that nobody can predict the future.

Plus, having clear financial agreements can actually strengthen your marriage by eliminating ambiguity and potential sources of conflict about money.

Common Postnup Scenarios

The Entrepreneur: You started a side business that's now bringing in serious money. Without a postnup, your spouse could have a claim to half of everything you've built. A postnup can establish that your business remains your separate property.

The Inheritor: Your parents are talking about leaving you the family home or a significant inheritance. A postnup can ensure that inheritance stays separate property and doesn't get mixed in with marital assets.

The Career Changer: Your spouse went back to school for an advanced degree that's led to a huge salary increase. A postnup can address how that increased earning capacity is treated if you later divorce.

The Debt Collector: One of you has accumulated significant debt (student loans, business debt, credit cards) that the other spouse doesn't want to be responsible for. A postnup can keep those debts separate.

What Makes a Postnup Different from a Prenup

Postnups face more legal scrutiny than prenups because you're already married when you create them. Courts worry that one spouse might have pressured or coerced the other into signing an unfavorable agreement.

This means postnups need to be especially fair and carefully drafted. Both spouses need independent legal representation, full financial disclosure, and time to review and consider the agreement. You can't just download a template from the internet and expect it to hold up in court.
