1. How to Divide the Account
The most common division is a percentage split of the account balance as of a specific date—usually the date of divorce or separation. But 401(k) plans often have both employee and employer contributions. It’s important to understand:
- Employee Contributions: Always 100% vested and subject to division.
- Employer Contributions: May be subject to a vesting schedule. Only the vested portion can be divided by QDRO. Unvested amounts are typically forfeited.
This makes accurate plan data and timing critical in determining what the alternate payee is entitled to receive.
