1. Contributions: Employee vs. Employer
Most 401(k) plans include both employee contributions (deferred from salary) and employer contributions (matching or non-matching). Only vested employer contributions are available for division under a QDRO. If your divorce occurs while one spouse has unvested employer contributions, those funds may not be included in the division unless and until they vest according to the plan’s vesting schedule.
If the divorce decree doesn’t address how to handle unvested balances, you could miss out on a substantial portion of intended benefits. We usually recommend language in the QDRO that covers both vested and post-divorce vested funds when applicable.
