Employee vs. Employer Contributions
One major detail to clarify is how employer contributions will be treated. In most 401(k) plans, employees contribute through salary deferral, and employers may match those contributions. However, employers usually attach a vesting schedule to their match. Your QDRO should specify whether:
- Only vested amounts are divided, or
- The alternate payee is entitled to future vesting (rare, but possible depending on the case)
Getting this language right impacts the final account share significantly—especially when employer matching is a big component.
