1. Employee and Employer Contributions
401(k)s include both employee deferrals and employer contributions. In divorce, the most common method of division is using a formula like 50% of the account balance as of a specific valuation date. But here’s the kicker—employer contributions are often subject to vesting schedules. That affects what portion is divisible.
- Fully Vested Contributions: These can be divided normally under the QDRO.
- Unvested Contributions: The alternate payee may not have any rights to these. If the employee spouse terminates employment before full vesting, unvested amounts may be forfeited.
