1. How Employee and Employer Contributions Are Treated
401(k) plans typically include contributions from both the employee and possibly the employer. If you’ve only been married for part of the contribution history, you’ll need to determine what portion of the funds is marital and thus divisible through a QDRO.
Contributions made during the marriage are generally considered marital property, while those made before marriage may be excluded. The QDRO must clearly reflect this distinction.
