Employee vs. Employer Contributions
Employee contributions are always fully vested and subject to division. However, employer contributions may be partially or entirely unvested, depending on when they were made and the plan’s vesting schedule.
If your spouse has unvested employer matches, those should be explicitly excluded or conditionally addressed in the QDRO. If the participant becomes fully vested in the future, you may want wording to allow you to receive a portion of those assets if they become available.
