STATE GUIDE · UPDATED 2026
Every OurPrenup agreement is built for the laws where you live.
Start your Colorado prenupYes — prenuptial agreements are legally enforceable in Colorado under the Uniform Premarital and Marital Agreements Act (UPMAA) (C.R.S. § 14-2-301 et seq.). To be valid, the agreement must be in writing, signed voluntarily by both partners, and made with fair financial disclosure. It should be notarized (strongly recommended, though not legally required), and both partners should have a real opportunity to review it well before the wedding.
Courts divide marital property fairly (not necessarily equally) unless your agreement says otherwise.
Yes. Colorado enforces prenuptial agreements under the Uniform Premarital and Marital Agreements Act (UPMAA). The governing law is C.R.S. § 14-2-301 et seq.. The agreement must be in writing and signed by both partners, entered into voluntarily, and made with fair financial disclosure.
Notarization is not strictly required in Colorado, but strongly recommended — a notarized agreement is significantly harder to challenge in court, and OurPrenup's Colorado signing instructions include it.
No — Colorado does not require witnesses for a prenuptial agreement. Both partners' signatures (ideally notarized) are what matter.
Colorado requires that each partner have a meaningful opportunity to consult their own lawyer before signing — you can waive it, but the opportunity must be real. OurPrenup's timeline and documents are built around that requirement.
No. Colorado is an equitable distribution state — without an agreement, courts divide marital property "fairly," which is not necessarily equally. A prenup replaces that uncertainty with rules you both chose.
Yes — Colorado allows couples to set, limit, or waive spousal support in a prenup, subject to fairness review and statutory safety valves that protect a spouse from being left in hardship. OurPrenup offers a full waiver, payment formulas with amounts you choose, or leaving support to state law.
Each partner must make a fair and reasonable disclosure of their assets, debts, and income before signing. Hiding assets is the fastest way to make a prenup unenforceable in Colorado. OurPrenup builds sworn financial disclosure schedules for both partners into every agreement.
Colorado has no fixed statutory deadline, but signing well before the wedding matters: agreements signed days before a wedding are the easiest to attack as pressured. Most attorneys recommend having the agreement finished at least 30 days before the wedding.
Attorney-drafted prenups in Colorado commonly run $1,500–$5,000+ per couple.
