Employee vs. Employer Contributions
Employee deferrals are always 100% vested. However, employer matching or profit-sharing contributions may be subject to a vesting schedule. The QDRO should be clear about whether the alternate payee is receiving only vested amounts or a share of the full account subject to vesting rules. Otherwise, you may inadvertently assign an interest in funds the employee-spouse may lose if they leave the company before being fully vested.
