Vesting Schedules
401(k) plans usually include both employee contributions (always 100% vested) and employer contributions, which may be subject to vesting schedules. In the Decco, Inc.. 401(k) Ps Plan, employee elective deferrals are fully vested, but matching or profit-sharing contributions from the employer may be only partially vested based on years of service.
If your ex-spouse hasn’t met the full vesting requirements, any unvested portion is forfeited—and you can’t claim it through a QDRO. Make sure you or your attorney get a vesting statement from the plan administrator.
