1. Employee and Employer Contributions
401(k) plans often include both employee salary deferrals and employer matching funds. When splitting the account, a QDRO can be written to include:
- Only the marital portion of employee contributions (typically from the date of marriage to the date of separation or divorce).
- The vested portion of employer contributions.
This matters because employer contributions may not be fully vested, which could reduce the alternate payee’s share.
