Employee and Employer Contributions
Employee contributions are generally 100% vested and can be divided without restrictions. However, employer contributions may be subject to a vesting schedule. If the employee spouse hasn’t met all vesting requirements, the alternate payee may not be entitled to a full share of employer-provided funds.
For example, if the participant is only 60% vested at the time of divorce, an alternate payee can only be awarded the vested portion. A well-drafted QDRO must address this, either by using the vested amount as of the division date or tracking future vesting if agreed by the parties — though not all plans will permit that second option.
