A prenuptial agreement does a lot more than most people expect. Most couples know it covers who gets what if the marriage ends, but the details matter far more than the concept. Knowing what belongs in yours, and what doesn’t, can mean the difference between an agreement that holds up and one that falls apart when you need it most.

What Colorado Law Allows You to Address

Colorado follows the Uniform Premarital and Marital Agreements Act (UPMAA), which gives couples wide latitude to customize their financial rights before marriage. The agreement must be in writing, signed by both parties, and supported by full financial disclosure, meaning you both need to honestly lay out your assets, debts, and income before signing.

Within those boundaries, a Colorado prenup can cover a lot of ground.

Property: What’s Yours, Mine, and Ours

This is where most prenups do their heaviest lifting. Colorado is an “equitable distribution” state, which means that if you divorce, a judge will divide marital assets fairly—not automatically 50/50. A prenup lets you define in advance what stays separate and what becomes shared, rather than leaving that call to a courtroom.

One thing many Colorado couples miss: under state law, the appreciation (growth in value) of your premarital property is generally treated as marital property during the marriage. So if you owned a home or an investment account before the wedding and it grew in value over the years, that growth is likely to be divided, unless your prenup says otherwise. If protecting what you brought into the marriage matters to you, this clause is essential.

Debt Allocation

A prenup can assign responsibility for existing and future debts. If your partner has student loans, a prenup can establish that they remain their obligation. The same applies to business debt, credit cards, or any other liabilities. Without this language, debts acquired during the marriage will be treated as shared, even if only one of you ran them up.

Spousal Maintenance

Colorado uses the term “maintenance” for what most people call alimony. Your prenup can specify whether maintenance will be paid if you divorce, how much, and for how long — instead of leaving those decisions to a judge applying Colorado’s default guidelines.

One important caveat: a Colorado court can decline to enforce a maintenance clause it finds “unconscionable” at the time of divorce, meaning grossly unfair given how your circumstances changed. That’s not a reason to skip the clause. It’s a reason to draft it thoughtfully, with terms that account for realistic scenarios.

Business Interests and Inheritance

If you own a business, hold equity in a startup, or expect a significant inheritance, your prenup is the right place to address it. You can establish that a business remains your separate property and that its growth isn’t subject to division. You can also protect assets you want to pass to children from a prior relationship, ensuring your prenup and estate plan work together rather than against each other.

What a Colorado Prenup Cannot Include

A few things are off the table entirely. Colorado courts will not enforce prenup provisions about child custody or child support. Those decisions are made based on the best interests of the child at the time of any divorce, regardless of what a prenup says.

A prenup also can’t include terms a court later finds unconscionable — such as provisions that would leave one spouse completely without resources — or anything that violates public policy, like penalizing a spouse for filing for divorce.

Including unenforceable provisions doesn’t automatically void your entire agreement, but it introduces real risk. If those provisions are closely tied to the rest of the document, you could lose more than just that one clause.

 
A Few Things Worth Getting Right

Timing matters. Colorado law requires both parties to have a reasonable opportunity to seek independent legal counsel before signing. That means starting the process months before the wedding, not the night before.

Financial disclosure isn’t optional. Each party needs a clear picture of the other’s financial situation. An agreement that conceals assets or misrepresents debts is vulnerable to being thrown out entirely.

Each person should have the opportunity to review the agreement with their own lawyer, even if one of you ultimately chooses not to hire one or decides to work with the same one.
