1. Dividing Employee and Employer Contributions
Most 401(k)s include both employee deferrals and employer contributions. The QDRO should specify whether it’s dividing just the marital portion or the full balance. Time-based formulas are often used when only a portion of the retirement was earned during the marriage.
In a 401(k), employer contributions are typically subject to a vesting schedule. That means the employee may not own 100% of them yet. A good QDRO accounts for this by limiting the alternate payee’s share to the vested portion only. Make sure this is clarified to avoid unnecessary disputes.
