Employee Contributions vs. Employer Contributions
Your QDRO should distinguish between the employee’s own contributions to the 401(k) and the employer matching or profit-sharing contributions. Often, employer contributions are subject to a vesting schedule. This means the employee may not be entitled to the full employer-funded portion unless they’ve worked at the company for a specified period.
Check to see if any employer contributions are unvested, and make sure your QDRO only assigns vested portions to avoid delays or rejections from the plan administrator.
