Employee vs. Employer Contributions
Most people assume the entire 401(k) balance is divisible. But with this plan, the source of each dollar matters. Employee contributions are 100% vested and divisible. Employer matches may not be fully owned (vested) by the employee unless certain criteria, like years of service, are met.
In your QDRO, you must clearly state whether you want to divide just the vested portion of the 401(k), or if you want the alternate payee (usually the non-employee spouse) to also receive a share of any future vesting. This distinction can lead to significantly different outcomes.
