Employee and Employer Contributions
Most 401(k) plans, including the Cascadia Consulting Group 401(k) Plan & Trust, have both employee contributions (which are fully vested from day one) and employer contributions, which may be subject to a vesting schedule. Your QDRO should specify how both types of funds are to be divided.
Employer contributions that are unvested as of the date of divorce—or the date selected in the QDRO (such as the date of separation)—typically stay with the participant. A good QDRO will clearly define what portion of the account is subject to division and what happens to unvested funds.
