How Are Retirement Accounts Divided in a Colorado Divorce?

Retirement Accounts Are Marital Property

If either spouse contributed to a retirement account during the marriage, the contributions and their growth are marital property under Colorado law. This applies to 401(k)s, 403(b)s, traditional and Roth IRAs, pensions, deferred compensation plans, and government retirement accounts. The marital portion is subject to equitable division — even if the account is held solely in one spouse's name.

Contributions made before the marriage remain separate property of the account holder, but any appreciation on those premarital contributions during the marriage is classified as marital property.

401(k) and 403(b) Plans: You Need a QDRO

Employer-sponsored plans governed by ERISA — including 401(k)s, 403(b)s, and traditional defined-benefit pensions — cannot be divided without a Qualified Domestic Relations Order (QDRO). This is a separate court order drafted independently from the divorce decree.

A QDRO tells the plan administrator exactly how to split the account: how much goes to the alternate payee (the non-employee spouse), whether it's a lump sum or periodic payments, and the effective date. The plan administrator must approve the QDRO before any funds move.

The QDRO process typically works like this:

1. The divorce decree or separation agreement specifies the division (e.g., 50% of the marital portion)
2. An attorney or QDRO specialist drafts the order according to the plan's specific requirements
3. The court signs it
4. The plan administrator reviews and approves it
5. The funds are transferred or a separate account is established for the alternate payee

Having the QDRO drafted and submitted promptly matters. If the account holder dies or takes distributions before the QDRO is processed, the alternate payee may lose their share.

IRAs: A Different Process Entirely

Individual Retirement Accounts are not governed by ERISA, so QDROs don't apply to them. Instead, IRAs are divided through a "transfer incident to divorce" under IRC § 408(d)(6).

To execute this tax-free:

• The division must be required by the divorce decree or separation agreement
• The transfer must be trustee-to-trustee (directly between custodians), rather than a personal withdrawal

The critical mistake people make with IRAs: the account owner withdraws the money personally and writes a check to the ex-spouse. The IRS treats this as a taxable distribution to the original owner — full income tax plus a 10% early withdrawal penalty if under 59½. The fact that the money went to an ex-spouse pursuant to a court order doesn't matter. The 60-day rollover exception generally doesn't save this either, because the IRS views a personal withdrawal followed by a deposit into someone else's IRA as a failed rollover rather than a transfer incident to divorce.

Always use a trustee-to-trustee transfer. Contact both custodians, provide them with the signed decree, and let them handle the paperwork.

Roth IRAs and Tax Basis

Roth IRAs add a layer of complexity because contributions were made with after-tax dollars. When dividing a Roth IRA, the tax basis (total contributions, which can be withdrawn tax-free) should be allocated proportionally between the accounts. If the receiving spouse gets 50% of a $100,000 Roth IRA with $60,000 in contributions, they should receive $50,000 total with $30,000 in basis.

This matters because withdrawals of basis from a Roth IRA are always tax-free and penalty-free, while withdrawals of earnings before age 59½ and before the 5-year holding period may be taxed and penalized. An uneven basis allocation can create a meaningful tax difference years down the road.

Valuation Date and Market Risk

Colorado law values assets as of the decree date, or as of the date of the final hearing on disposition of property if that hearing comes first, not the physical-separation date. If the stock market drops 20% between the day you physically separate and the day the decree is entered, both spouses share that loss. This creates a period of shared market risk that can last months.

To manage this, many separation agreements define a "date of segregation" — a fixed date that locks in the alternate payee's share. Market fluctuations after that date accrue only to the respective account holder. Without this provision, valuation disputes are almost guaranteed if the market moves significantly during the case.
