Unvested Employer Contributions
One of the key details that can trip people up is the vesting schedule. 401(k) plans often have employer contributions that are subject to vesting—meaning the employee earns the right to keep the funds over time. If the employee isn’t fully vested at the time of divorce, the QDRO must specify that only the vested portion is subject to division.
Any non-vested employer contributions will likely be forfeited, so it’s essential for the QDRO to clearly define what portion of the benefits the alternate payee is entitled to. If this is not properly addressed, the alternate payee could receive nothing or something less than expected.
