1. Employee vs. Employer Contributions
401(k) accounts include both employee deferrals and often a matching or profit-sharing contribution from the employer. In many plans, employer contributions are subject to a vesting schedule, meaning the employee only fully owns them after a certain amount of service.
If you’re the alternate payee (non-employee spouse), make sure your QDRO addresses whether you’re entitled only to vested assets or also to any unvested portion accrued during the marriage. Plan documents will specify how unvested amounts are handled if a divorce occurs.
