Employee vs. Employer Contributions
Employee contributions are almost always 100% vested—meaning the funds belong fully to the employee. Employer contributions, however, often follow a vesting schedule. If the employee hasn’t worked at Kazzco, Inc.. 401(k) plan long enough, some of those amounts may not yet be owned (or “vested”) at the time of separation or divorce.
Your QDRO should distinguish between vested and unvested amounts and clarify how to handle changes in vesting after the divorce. This can determine how much the alternate payee ultimately receives.
