1. Vesting Schedules
Employer contributions to a 401(k) are often subject to a vesting schedule. Only the vested portion of the account can legally be awarded to the non-employee spouse. Any unvested employer contributions are considered forfeitable—meaning they may revert to the plan if the employee does not stay long enough to become fully vested. A well-drafted QDRO should specifically address how the division will treat non-vested funds in case they later become vested.
