Employee and Employer Contributions
Most 401(k) plans include contributions made by both the employee (participant) and the employer. In divorce, only the portion earned during marriage is typically subject to division.
But it gets complicated with employer contributions. Those funds are often tied to a vesting schedule. So, not all contributions made during marriage may be fully owned by the participant when the divorce occurs. The QDRO needs to account for this distinction and clarify whether orders include only vested funds or future vesting as well.
