Employee and Employer Contributions
Generally, the portion of the employee’s account contributed during marriage is considered marital property and subject to division. However, employer contributions can be trickier depending on the vesting schedule. If your spouse received employer matches that weren’t fully vested at the time of divorce, you may not be entitled to those funds.
A good QDRO will clarify whether the division applies only to vested amounts and how any unvested portions are handled if they later vest.
