Employee and Employer Contribution Division
This plan likely includes both employee salary deferrals and employer-matching contributions. Each of these sources may have different investment histories, tax treatment, and—most importantly—vesting schedules. Your QDRO needs to specify whether it covers just the vested portion, or if the alternate payee is entitled to a share of future vesting as well.
If only a portion of employer contributions has vested by the date of divorce, any unvested balance may be forfeited if the participant separates from service. This is important to clarify so the alternate payee isn’t expecting a share of funds that may not ever become payable.
