1. Employee vs. Employer Contributions
401(k) plans often include contributions from both the employee and the employer. Typically, the employee’s contributions are 100% vested right away. However, employer contributions often follow a vesting schedule. The QDRO must account for which amounts are actually vested as of the agreed-upon division date.
If your spouse is the plan participant and has unvested employer contributions, the alternate payee (you) may not be entitled to that portion unless and until those contributions vest. This detail is critical during QDRO drafting, especially if you’re dividing the account as of a past date.
