Employee and Employer Contributions
In most 401(k) plans, contributions come from both the employee and employer. Dividing the plan fairly requires distinguishing between:
- Employee contributions: Always considered marital property if made during the marriage
- Employer contributions: Subject to vesting; unvested amounts may not be divisible at the time of divorce
Your QDRO should specify if the alternate payee is entitled only to vested funds or also to future vesting linked to the period of marriage. If that’s not addressed, disputes or miscalculations can occur.
