1. Employee vs. Employer Contributions
Most 401(k) plans consist of two main contribution types: money that the employee defers (pre-tax or Roth) and employer contributions (matching or discretionary). These may be subject to vesting based on your time with the company.
- If the employee contributed during the marriage, the QDRO should clearly state how to divide those marital contributions and gains/losses.
- For employer contributions, the QDRO must account for whether those retirement funds are fully or partially vested at the time of divorce.
- Unvested employer contributions usually remain with the employee and can’t be transferred to the former spouse.
