1. Employee vs. Employer Contributions
In most 401(k) plans, the account includes two main contributions: those made by the employee and those matched or contributed by the employer. QDROs can divide both, but timing matters.
- Employee contributions are always the participant’s property and usually divisible
- Employer contributions may be subject to a vesting schedule —meaning the participant hasn’t “earned” them yet
If the divorce occurs before full vesting, the non-employee spouse might receive less than anticipated. It’s critical to reference vesting rules in your QDRO to avoid disputes or shortfalls down the road.
