Employee vs. Employer Contributions
The plan likely includes both employee contributions (funded through paycheck deductions) and employer contributions (typically a match or discretionary deposit). QDROs can be drafted to divide just the employee portion, both employee and employer contributions, or any customized allocation.
Keep in mind: Some employer contributions are subject to a vesting schedule, meaning the employee may not fully own them yet. These unvested amounts may be excluded if the division date is earlier than full vesting.
