7 Reasons a Colorado Judge Will Throw Out Your Prenuptial Agreement
A Colorado District Court judge can invalidate a prenuptial agreement if it violates the Uniform Premarital and Marital Agreements Act. Common reasons for invalidation include fraudulent financial disclosure, denying a spouse access to independent legal counsel, or terms that leave a spouse reliant on public assistance.
A prenuptial agreement is designed to provide peace of mind, but it is not an unbreakable ironclad shield. When couples file for a dissolution of marriage in Denver, Boulder, or Fort Collins, the disadvantaged spouse will often challenge the validity of the prenup to secure a better financial settlement. In Colorado, marital agreements are governed by the Colorado Uniform Premarital and Marital Agreements Act (C.R.S. § 14-2-301) under C.R.S. § 14-2-309.
Family court judges have broad authority to review these contracts. If they find that the agreement was drafted unfairly, signed under pressure, or violates state public policy, they can throw out specific clauses or invalidate the entire document. If your prenup is thrown out, your assets will be divided according to standard Colorado equitable distribution laws. Understanding the common pitfalls that destroy prenups is essential to ensuring your agreement survives a legal challenge.
Step-by-Step Process for Challenging a Prenup in Colorado
If you believe your prenuptial agreement is unfair and illegal, you must formally challenge it during your divorce proceedings.
Step 1: Filing the Petition for Dissolution
The process begins when one spouse files a Form JDF 1101, Colorado, Judicial Branch, Petition for Dissolution of Marriage or Legal Separation with the local District Court, such as the Denver District Court, Denver. In your initial filings or response, you will indicate that a marital agreement exists but that you intend to challenge its enforceability.
Step 2: Issuing Discovery Requests
Your attorney will initiate the "discovery" phase. They will request financial documents from the time the prenup was signed to compare them against the disclosures your spouse made back then. If they hid a bank account or undervalued a business, discovery may help uncover hidden assets or financial discrepancies.
Step 3: Filing a Declaratory Judgment Motion
Your lawyer will file a formal motion asking the judge to declare the prenuptial agreement invalid. The motion will cite specific violations of the Colorado Uniform Premarital and Marital Agreements Act under C.R.S. § 14-2-309, such as duress or lack of proper legal warnings.
Step 4: The Evidentiary Hearing
The judge will hold an evidentiary hearing where both sides present evidence and witness testimony. The judge will examine the circumstances surrounding the signing of the agreement and make a final ruling on whether the prenup stands or falls.
7 Reasons a Colorado Court Will Invalidate Your Prenup
Colorado courts look for specific violations when reviewing marital agreements. If any of the following apply, your prenup is in serious jeopardy.
1. Incomplete or Fraudulent Financial Disclosure
Under Colorado law, you cannot waive your rights to someone's property if you do not know what that property is. If one spouse hid a retirement account, undervalued a piece of real estate, or failed to disclose massive credit card debt before signing, a judge may invalidate the agreement due to lack of transparent financial disclosure.
2. Lack of Independent Legal Representation
The UPMAA strongly protects the right to legal counsel. If the wealthier spouse refused to let the other spouse hire an attorney, or if the agreement lacks the bolded, statutory warning language required when a party voluntarily waives their right to counsel, the court will likely declare the agreement unenforceable.
3. Terms Violating Public Policy (Child Support)
You cannot use a prenup to limit child support or dictate child custody. The right to child support belongs to the child, not the parents. If a prenup contains a clause stating one spouse will never pay child support, the judge will immediately strike that clause because it severely violates Colorado public policy.
4. Waivers Leaving a Spouse Reliant on Public Assistance
Many prenups include a waiver of spousal maintenance (alimony). While generally legal, Colorado law has a strict exception. If waiving alimony means the disadvantaged spouse will be so destitute that they qualify for state public assistance (welfare), the judge will override the prenup and force the wealthier spouse to pay enough support to keep them off government aid.
5. Duress and Coercion Before the Wedding
A contract must be signed voluntarily. If one spouse presented the prenup on the eve of the wedding and threatened to cancel the ceremony unless it was signed immediately, the court will consider this severe coercion. Agreements signed under duress are entirely void.
6. Unconscionability at the Time of Enforcement
Under C.R.S. § 14-2-309(5), Colorado courts review unconscionability strictly at the time of enforcement during divorce proceedings, not at the time the agreement was signed. Furthermore, under Colorado's version of the UPMAA, substantive unconscionability cannot be used to invalidate property division terms if all procedural formation requirements were satisfied. Instead, unconscionability review applies solely to provisions determining, limiting, or waiving spousal maintenance, or allocating attorney fees. For instance, if a maintenance waiver would leave a former spouse facing severe financial hardship or unable to meet reasonable needs due to post-signing disability or economic changes, the judge may hold the waiver unconscionable at enforcement and award spousal support.
7. Improper Execution or Lack of Signatures
This is a simple but fatal error. If the document was never properly signed by both parties, or if oral promises were made that were never put into writing, the agreement is legally worthless. Prenuptial agreements in Colorado must be in writing and signed by both prospective spouses.
How Much Does it Cost to Litigate a Prenup in Colorado?
Challenging or defending a prenup in court is essentially a mini-trial within a divorce, which dramatically increases legal fees.
| Litigation Phase | Estimated Cost in USD |
|---|---|
| Filing Motions and Discovery | Gathering evidence of hidden assets can cost $3,000 to $7,000 in attorney fees. |
| Forensic Accountants | Hiring experts to prove fraudulent financial disclosure often ranges from $5,000 to $10,000. |
| Full Evidentiary Hearing | Taking the challenge to a judge for a final ruling can push total costs to $15,000 to $30,000+. |

How Long Does the Process Take?
Litigating the validity of a prenuptial agreement adds significant time to a divorce. The discovery phase, where attorneys subpoena old financial records, usually takes 3 to 6 months. Getting a date for a special evidentiary hearing in a busy Colorado District Court can add another 2 to 4 months. Overall, challenging a prenup can easily extend a standard divorce timeline by 6 to 12 months.
Frequently Asked Questions (FAQ)
Will the whole prenup be thrown out if one clause is illegal?
Generally, no. Most professionally drafted prenups include a "severability clause." This tells the judge that if one clause (like an illegal child support limit) is struck down, the rest of the agreement regarding property division should still be enforced.
Can an infidelity clause get a prenup thrown out?
Colorado is a strict "no-fault" divorce state. Judges generally frown upon "lifestyle clauses" or infidelity penalties. While they might not invalidate the entire agreement, judges frequently refuse to enforce financial penalties tied to marital misconduct.
Does a prenup expire after 10 years?
A prenup only expires if it contains a specific "sunset clause" stating that it becomes invalid after a certain number of years of marriage. If there is no sunset clause, the prenup lasts until death or divorce.
Can we verbally agree to change the prenup later?
No. Under the UPMAA, any amendments or revocations to a prenuptial agreement must be made in writing and signed by both parties. Verbal agreements to cancel the prenup will not hold up in court.
