Employee vs. Employer Contributions
When dividing a 401(k), you must distinguish between what the employee contributed and what the employer contributed. This is especially important if the employer contributions are subject to a vesting schedule, as is commonly the case.
In many divorces, each party is entitled to half of the marital portion of the account. However, if a portion of the employer match hasn’t vested yet, the non-employee spouse (alternate payee) may not receive part of those funds. You need to review the plan’s vesting rules and specify in the QDRO that unvested benefits are excluded—or clarify how to treat them if they become vested later.
