Why a Colorado prenup is different

A First prenup is built around the laws of Colorado, and you, from the ground up.

Colorado tests four things, and any one can sink an agreement

Colorado's statute asks only for a written record signed by both partners, with no notary or witnesses. But a court will refuse to enforce it on any one of four grounds: signing that was not voluntary or was the result of duress; no access to independent legal advice; no lawyer and no notice or plain-language explanation of the rights being given up; or financial disclosure that was not adequate.

Hiring a lawyer is not required, having time is

Colorado does not require either of you to be represented. What it requires is that neither of you was rushed: a reasonable stretch of time before signing, so the decision was yours to make unpressured. Sign months ahead with full disclosure on both sides and that condition is met. Maintenance and attorney-fee terms face a second check for unconscionability at enforcement.

Growth in what you already own is marital by default

Without a prenup, a Colorado court divides marital property in the proportions it deems just, weighing each spouse's contributions, including as a homemaker. Just doesn't always mean equal. And marital property includes any increase in value during the marriage of property either of you owned beforehand or received as a gift or inheritance. A prenup is how you two decide what stays separate instead.

What your $649 Colorado prenup includes

One price per couple, not per partner. Everything below is included.

  • Customized to Colorado law and to your finances, not a fill-in-the-blank template
  • Built on a foundation drafted with experienced family law attorneys
  • Guided questionnaire both partners complete separately, from any device
  • Structured financial disclosure tools for both partners, which is one of the four things the Colorado test checks
  • Covers real estate, retirement, business ownership, equity, inheritance, gifts, debts, pet custody, and more
  • Online notarization included at no extra cost
  • Save and resume anytime, so both partners have time to review before signing
  • $649 flat. No retainer, no hourly bills, no per-partner pricing. Finish at your own pace.

First vs hiring two Colorado attorneys on your own

Key considerations

A Colorado prenup is $649 flat for the couple through First, completed online with notarization included. Hiring two attorneys separately in Colorado, where family law attorneys average $327 an hour and the Denver area runs $280 to $600, commonly lands between $3,000 and $14,900 for the couple.

Hired separately, a prenup is quoted per partner and often billed hourly, so the final number is hard to predict before you start. First is one flat price for both of you, with no retainer and no hourly bills.

The fees also price only the legal work. Hiring on your own means building a shortlist of Colorado family law attorneys, calling each one, booking consults, and confirming both fees and availability against your wedding date, then running all of it again because your partner needs a different attorney. First replaces this work with a process the two of you complete together, at your own pace, from anywhere in the state.

  • Deciding spousal maintenance now, whether that means waiving it or setting it in advance

Colorado prenup questions, answered

Is a prenup enforceable in Colorado?

Yes, if it clears Colorado's four-part test. The agreement must be a written record signed by both partners. A court will refuse to enforce it if the partner challenging it proves they did not sign voluntarily, did not have access to independent legal representation, had no lawyer and the agreement did not include a notice or plain-language explanation of the rights being given up, or did not receive adequate financial disclosure before signing. Terms on spousal maintenance and attorney fees can also be refused if they are unconscionable when enforced.

How much does a prenup cost in Colorado?

With First, a Colorado prenup is $649 flat for the couple, with online notarization included. Hiring attorneys instead commonly runs $3,000 to $14,900 for the couple, billed hourly at Denver-area rates of $280 to $600 an hour, since each partner needs their own attorney and the hourly math runs twice. Our guide to what a prenup costs walks through that math.

Do you do prenups in Denver, Colorado Springs and Boulder?

Yes. First serves couples across Colorado, including Denver and suburbs such as Aurora, Lakewood and Littleton, Boulder, Colorado Springs, Fort Collins, Pueblo and Grand Junction. Self-Serve is $649 flat for the couple and is completed online, so where in the state you live does not change the process or the price.

How much does a prenup cost in Denver?

Denver-area family law attorneys commonly bill $280 to $600 an hour. Because each partner needs their own, hiring two separately commonly runs $3,000 to $14,900 for the couple. First is $649 flat for the couple, with online notarization included.

Do both people need a lawyer for a prenup in Colorado?

No. Colorado does not require either of you to be represented, and prenups are routinely signed without attorneys. What the statute asks is that the choice was unpressured: enough time before signing that neither of you was cornered, adequate financial disclosure on both sides, and, for a partner signing without their own attorney, plain-language notice of the rights the agreement gives up. First Self-Serve is built to deliver all three, at $649 for the couple instead of two hourly bills.

Can I do a Colorado prenup online?

Yes. Colorado's statute asks for an agreement in a record signed by both partners, and nothing in it treats an agreement differently because of how it was produced. What matters is that both partners signed voluntarily, each had access to independent legal advice, each received adequate financial disclosure, and the agreement was drafted to Colorado law. First Self-Serve is $649 for the couple and includes online notarization.

Does a Colorado prenup have to be notarized?

No. Colorado's statute requires the agreement to be in a record and signed by both partners; it does not require notarization or witnesses. Notarizing is still worth doing, because a notarized signature is straightforward evidence that both partners signed, and voluntary consent is the first thing a Colorado court examines. First includes online notarization at no extra cost.

When should we sign a prenup in Colorado?

Early enough that neither of you is deciding under pressure. Colorado builds timing into the statute: the law asks that each partner had a reasonable stretch of time before signing, unrushed. An agreement produced days before the ceremony is the fact pattern most likely to fail that test. Signing months ahead removes the argument, and Self-Serve lets you work through it at your own pace.

Is First Self-Serve right for a complex Colorado prenup?

Yes. Self-Serve covers business ownership, stock, options and RSUs, real estate, inheritance and gifts, existing child support or maintenance obligations, and spousal maintenance terms, all for $649 flat for the couple. If you'd like to talk your situation through first, book a free 20-minute call.

What does a Colorado prenup cover?

A Colorado prenup can set out what counts as separate and marital property, including whether growth in value of what either of you already owns stays separate, how property and debts are divided if the marriage ends, and spousal maintenance. There are limits. It cannot adversely affect a child's right to support, terms about parenting do not bind a court, and maintenance or attorney-fee terms that are unconscionable when enforced can be set aside.
