1. Employee vs. Employer Contributions
With 401(k) plans, contributions typically come from both the employee and the employer. The employee’s contributions are always theirs, but employer contributions are often subject to vesting schedules.
- Vested amounts: Only the vested portion of the employer contributions is available for division in a QDRO.
- Unvested amounts: These are forfeitable and typically can’t be divided—even if marital property laws suggest otherwise.
During QDRO drafting, it’s critical to verify what portion of the account balance is legally considered vested so you don’t waste time (or legal fees) trying to award funds that aren’t actually available.
