Employee vs. Employer Contributions
Most 401(k) plans include contributions from both the employee and the employer. In many cases, only the employee’s contributions are 100% vested, while the employer’s contributions may be subject to a schedule.
Be sure your QDRO clearly states whether the alternate payee is entitled only to vested funds, or also to a portion of unvested amounts based on the length of the marriage. Some courts award a share of the entire account accrued during marriage, vested or not.
