Employee and Employer Contributions
401(k) plans typically contain both employee-deferral contributions and employer-matching or profit-sharing contributions. In a QDRO, both types of contributions may be divided depending on the date of marriage and the timing of contributions through the divorce or cutoff date. This matters because:
- Employee contributions are always 100% vested.
- Employer contributions may be partially or fully unvested at the time of divorce.
The QDRO must clearly state how vested versus unvested funds are treated to avoid confusion or disputes with the plan administrator.
