Employee vs. Employer Contributions
Most 401(k) accounts consist of employee salary deferrals and employer matching or discretionary contributions. In some divorces, the alternate payee (the non-employee spouse) may be awarded a share of the total account balance, or only a portion of the marital contributions. Here’s the catch with employer contributions: they’re often subject to a vesting schedule.
If employer contributions haven’t fully vested at the time of the divorce, those unvested amounts may not be divided. The QDRO for the Ogs 401(k) Plan needs to clarify whether the alternate payee’s share includes only vested amounts or if the order will follow post-divorce vesting (which may or may not be allowed under the Plan’s rules).
