1. Employee vs. Employer Contributions
When dividing a 401(k), you must first determine which funds are fair game. Typically, any earnings and contributions made during the marriage are considered marital property. But 401(k)s often include both:
- Employee Contributions (Participant Deferrals): These are the portions the employee directs into the account from their paycheck. These are always 100% vested.
- Employer Contributions (Matching or Profit Sharing): These funds might be subject to a vesting schedule, meaning some of the funds may not be “owned” by the employee yet, depending on how long they’ve worked at the company.
If your QDRO doesn’t account for vesting status correctly, it could result in an incorrect calculation or a frustrating rejection from the plan administrator.
