Employee and Employer Contributions
The B & T Building Services, Inc.. 401(k) Plan likely includes both employee salary deferrals and matching or discretionary employer contributions. It’s common to divide only the marital portion —which typically includes all contributions and gains accrued during the period of marriage.
If the employer contributions are subject to a vesting schedule, you’ll need to determine what portion (if any) of those contributions were vested as of the date of divorce or division. Only vested amounts can be divided by QDRO.
