1. Employee vs. Employer Contributions
In a divorce, not all 401(k) contributions are treated equally. Employee contributions are fully vested immediately. That means if the participant put in $50,000 themselves, that amount can be split without issue.
Employer contributions—also known as matching or discretionary contributions—often have vesting schedules. If an account has unvested employer contributions, those can’t be divided. A QDRO for the The Adam Corporation/group 401(k) Plan must include language to handle this so the alternate payee isn’t awarded something that may eventually be forfeited.
