A prenuptial agreement (prenup) is a written contract you sign before the wedding. It sets clear rules for property, debt, and (where allowed) support — so you’re not relying only on default state laws. Here’s the plain-English version of how it works.
What a prenup actually does
- Defines what stays separate vs. what becomes marital/community property.
- Sets rules for savings, debt, and how you’ll handle big purchases.
- Addresses spousal support (within public-policy limits).
- Plans for life events: a home purchase, business growth, career breaks, or moving states.
What it doesn’t do
It doesn’t decide child support or custody — that’s handled later by a court based on the child’s best interests.
Keys to a strong prenup
- Start early; avoid last-minute pressure.
- Exchange clear financial disclosures (assets, debts, income).
- Use plain language; consider independent counsel for both partners.
- Sign properly (notarized) and keep originals safe.
