1. Employer Contributions and Vesting Schedules
Many 401(k) plans include employer matching contributions that are subject to a vesting schedule. This means that part of the employer money may not belong to the employee unless they’ve worked at the company long enough. If a participant leaves before full vesting, the unvested portion is forfeited and can’t be shared in a QDRO.
For example, if the participant is 60% vested, only that 60% of employer contributions can be divided with the alternate payee (typically the ex-spouse). A QDRO must be clear about how to handle these contributions and include language that prevents disputes or administrative rejection.
