1. Employee vs. Employer Contributions
Most 401(k) accounts include:
- Employee salary deferrals (pre- or post-tax)
- Employer matching or profit-sharing contributions
For divorce purposes, you must determine what portion of the contributions were made during the marriage. Employer contributions may be subject to a vesting schedule, so the order should be written to include only the vested portion as of the time the QDRO is processed.
