1. Employee and Employer Contributions
The first thing to look at is how contributions are made into the plan. Most 401(k) plans include:
- Pre-tax employee contributions
- Employer matching contributions
Only vested employer contributions are typically subject to division. The QDRO should specify whether the alternate payee (usually the ex-spouse) will receive a portion of vested employer funds as of a particular date—commonly the date of divorce or separation.
