1. Employee vs. Employer Contributions
401(k)s consist of both employee contributions (which are always 100% vested) and employer contributions (which may be subject to vesting schedules). If the employee spouse is not fully vested, the alternate payee is only entitled to the portion that is vested as of the date of division. This detail must be clearly outlined in your QDRO to avoid disputes or overestimation of your entitlement.
