1. Employee vs. Employer Contributions
The first step in dividing this plan with a QDRO is to determine what portion of the account is open to division. All employee contributions are 100% vested and available for division. However, employer contributions may depend on a vesting schedule—which is common in 401(k)-style plans sponsored by private corporations.
If the employee has not worked long enough to become fully vested, part of the account balance may be forfeited when they separate from service. That means some contributions may not be available for division at the time of divorce unless the employee continues working and reaches full vesting later.
