Employee vs. Employer Contributions
With 401(k) plans, you’re typically dealing with two sources of contributions: the amounts the employee (your spouse or you) deferred from wages, and the employer match or other employer-funded contributions.
The QDRO can be structured to cover one or both of these types of contributions. Be aware that employer contributions may be subject to vesting – meaning your share might be limited if those contributions weren’t fully vested at the time of divorce.
