Employee Contributions vs. Employer Contributions
Employee contributions made to a 401(k) are usually 100% vested immediately. Employer contributions, however, may be subject to a vesting schedule. This means the participant may not fully own those funds unless they’ve worked at the clinic for a certain number of years.
Your QDRO should account for this by identifying which contributions are included in the division—many alternate payees find themselves awarded funds that later go to zero if unvested amounts are included incorrectly.
