Prenuptial Agreements in Colorado – Things To Consider

In Colorado, prenuptial agreements are legally recognized and governed by the Colorado Uniform Premarital and Marital Agreements Act (UPMAA).

A prenuptial agreement, also known as a prenup or premarital agreement, is a contract entered into by a couple before their marriage or civil union. It outlines the rights and obligations of each party regarding property, debts, and other matters in the event of a divorce, separation, or death.

Here are some key points about prenuptial agreements in Colorado:


If a prenuptial agreement is to be valid in Colorado, it absolutely must be in writing and signed by both parties voluntarily, without any coercion or duress. It becomes effective upon marriage.

Full Financial Disclosure

Both parties are required to provide a full and fair disclosure of their assets, liabilities, and income. Hiding assets or providing false information can render the agreement invalid.


Prenuptial agreements can address various issues, including property division, spousal support (alimony), division of debts, inheritance rights, and other matters. However, child custody and child support provisions cannot be predetermined or restricted by a prenuptial agreement, as these issues are determined based on the best interests of the child at the time of divorce or separation.


To be enforceable, a prenuptial agreement in Colorado must be fair and reasonable at the time of enforcement. Unconscionable provisions, such as those that significantly favor one party and leave the other party without adequate support, may not be upheld by the court.

Independent Legal Representation

While not required, it is advisable for each party to have their own independent legal counsel when creating a prenuptial agreement. This helps ensure that both parties fully understand the terms and implications of the agreement.

Modification or Revocation

Prenuptial agreements can be modified or revoked after marriage if both parties agree to the changes in writing.

It’s important to note that laws can evolve, and court interpretations can vary. Therefore, consulting with a family law attorney in Colorado is essential to understand the specific legal requirements and implications of a prenuptial agreement based on the most up-to-date information and circumstances.
