Employee and Employer Contributions
The easiest way to divide a 401(k) is to award the alternate payee (usually the former spouse) a percentage of the participant’s total account balance as of a specific date—often the date of separation. But it’s important to distinguish between:
- Employee Contributions: 100% vested and always divisible
- Employer Contributions: Often subject to a vesting schedule
If a portion of the employer match isn’t vested as of the division date, it can’t be awarded to the alternate payee. This is why your QDRO must include clear language about dividing vested vs. unvested amounts—or you may leave money on the table.
