Vesting and Forfeitures
One big hurdle in dividing a 401(k) is the vesting schedule. If the employer made matching or profit-sharing contributions, but the employee spouse hasn’t met the vesting timeline, part of the account won’t belong to them yet—and won’t be divisible in a QDRO. That’s why it’s crucial to understand exactly what’s vested as of the cutoff date (usually the date of separation or divorce).
