Understand Contribution Types
401(k) plans often include different types of contributions, which may be treated differently in a divorce:
- Employee Contributions: These are generally fully vested and can be divided immediately in a QDRO.
- Employer Contributions: These may have a vesting schedule. Unvested amounts at the time of divorce usually cannot be awarded to the alternate payee (the non-employee spouse).
- Roth vs. Traditional Accounts: Be sure to specify which account type is being divided. Tax treatment is different, and a mistake here could lead to IRS issues later.
