Employee vs. Employer Contributions
In 401(k) plans, employee contributions are always fully vested. However, employer contributions typically vest over time, depending on the plan’s rules. If the participant is not fully vested at the time of divorce, the non-participant spouse may not be entitled to a portion of the unvested employer contributions.
The QDRO should specify only the vested portion of the account at the time of division. If not, the plan administrator may reject the order or delay processing until clarification is provided.
