1. Vesting Schedules and Employer Contributions
If your spouse wasn’t fully vested in employer contributions at the time of divorce, they may lose some benefits. Each 401(k) plan has a vesting schedule—often based on the number of years the employee worked at the company. If a QDRO tries to assign unvested funds to you, the plan may reject it. Make sure the QDRO only divides the vested portion of employer contributions.
