Vesting Schedules and Forfeitures
Employer contributions to 401(k) plans typically aren’t fully owned by the employee until a vesting schedule is satisfied — often based on years of service. If your spouse hasn’t been with the museum employer long enough, some employer contributions may not be “vested” and could be forfeited after the divorce. QDROs can only divide vested assets.
It’s critical to identify what portion of the account is actually divisible. The plan administrator usually provides a vested balance breakdown upon request.
