1. Employee vs. Employer Contributions
In 401(k) plans, both the employer and the employee can contribute. Your QDRO should clearly state whether the alternate payee (usually the non-employee spouse) will share in just the employee contributions or both employee and employer contributions.
Keep in mind, employer contributions might be subject to vesting schedules. If your QDRO mistakenly includes unvested benefits, the alternate payee may end up with less than expected.
