Employee vs. Employer Contributions
When dividing the 401(k) assets, be aware that only vested employer contributions are available for division. The employee contributions are always fully vested, but employer contributions typically follow a vesting schedule (such as 3 years cliff or 6 years graded). If the employee spouse has unvested employer contributions at the time of divorce, those may not be included in the divided portion. This must be addressed clearly in the QDRO to avoid complications down the road.
