1. Employee and Employer Contributions
401(k) plans often contain both employee deferral contributions and employer matching or profit-sharing contributions. It’s critical to spell out whether the alternate payee (usually the non-employee spouse) is entitled to both or just the employee portion.
Some employer contributions are subject to vesting schedules. If the participant isn’t fully vested, the nonvested portion usually cannot be assigned or divided through a QDRO.
