Vesting Schedules and Forfeitures
One major point often overlooked is vesting. If the employee’s 401(k) account includes employer matching contributions, some or all of those may be unvested at the time of divorce. If a QDRO doesn’t clearly define how to handle those unvested funds—such as whether the alternate payee gets a share of future vesting or only what’s already vested—it can create costly problems later.
