1. Employee and Employer Contributions
The plan likely includes both employee salary deferrals and employer-matching or profit-sharing contributions. Contributions made by the employee (the participant) are usually 100% vested, while employer contributions may be subject to a vesting schedule. The QDRO must clearly distinguish between these contribution types and how each will be divided.
If the participant only partially owns employer contributions due to vesting requirements, the alternate payee (usually the ex-spouse) is not entitled to the unvested portion. The plan’s vesting details will be crucial in determining exactly how much is available for division.
