1. Employee vs. Employer Contributions
In most 401(k) plans, the account includes both employee contributions (what the participant put in) and employer contributions (matching or discretionary amounts the company added). In divorce, both can be divided—but only the vested employer contributions are available to the alternate payee (the spouse receiving a portion of the account).
Make sure your QDRO distinguishes between:
- Pre-marital and post-marital contributions
- Vested vs. unvested employer amounts
- Whether gains/losses after the division date should be included
