1. Employee vs. Employer Contributions
Contributions in a 401(k) plan typically come from both the employee and the employer. A proper QDRO needs to clarify whether the alternate payee is receiving a portion of all plan benefits, just employee contributions, or only the vested portion of employer contributions.
Employer contributions may be subject to a vesting schedule, and any unvested amounts as of the “valuation date” or divorce date may not be part of the alternate payee’s award.
