Unvested Employer Contributions
Many 401(k) plans have employer matching contributions subject to a vesting schedule. That means an employee must work a certain number of years before earning full rights to those funds. If the divorce happens before the participant is fully vested, only the vested amount will be eligible for division through a QDRO.
If you’re the non-employee spouse, you’ll want to ensure the QDRO only allocates the vested portion of the employer’s contributions. Attempting to divide unvested amounts can cause the QDRO to be rejected.
