Vested vs. Unvested Contributions
Many 401(k) plans, especially those in business entities like Merchant partners LLC 401k plan, include employer matching contributions that only become fully owned by the employee after a certain number of years of service—this is called the vesting schedule.
If the employee spouse hasn’t met the full vesting requirement at the time of divorce, the alternate payee will only be eligible to receive a portion of the vested balance. The QDRO must account for this and clarify that only vested benefits will be divided.
