Dividing Employee and Employer Contributions
401(k) plans are tax-deferred retirement accounts that grow through:
- Employee salary deferrals
- Employer matching or profit-sharing contributions
When you define what portion of the account the non-employee spouse will receive, it’s vital to spell out whether you’re dividing:
- The total account balance as of a specific date (e.g., date of separation or divorce judgment)
- Only marital contributions plus gains/losses—for example, from date of marriage to date of separation
Employer contributions may not be fully vested at the time of divorce. Your QDRO must clarify whether the alternate payee is entitled to just the vested balance—or if they can also receive future vesting on marital-period contributions. This is easy to get wrong without legal guidance.
