1. Unvested Employer Contributions
The plan is a 401(k)-style account, likely to include both employee deferrals and employer contributions. These employer contributions often come with a vesting schedule. If you’re the alternate payee (non-participant spouse), your share may only include vested amounts as of the cutoff or valuation date.
This becomes a major issue if you divide “50% of the account” without specifying if unvested amounts are included or excluded. The QDRO must address these details, or you risk losing part of your share (or being awarded more than can legally be assigned).
