Employee Contributions vs. Employer Contributions
401(k) accounts usually have two separate funding streams: money the employee puts in, and potentially additional money the employer contributes (also known as matching or profit sharing contributions). In a divorce, both are subject to division, but only if they’re earned during the marriage and vested.
Make sure your QDRO clearly defines what’s included. If you’re dividing only marital contributions, you’ll want language that specifies the date of marriage and date of separation or divorce judgment as cutoff points.
