Employee and Employer Contribution Division
Many 401(k) accounts consist of two funding sources: employee salary deferrals and employer matching contributions. In some cases, only the participant’s own contributions are considered marital property. In other cases, any employer matching funds that vested during the marriage may also be divided.
If you’re dividing the plan, make sure the QDRO specifies whether both sources are to be included. This distinction is especially important if some of the employer’s contributions are not yet fully vested.
