1. Employee and Employer Contributions
With most 401(k) plans, both the employee and employer make contributions. During divorce, it’s standard practice to only divide the marital portion of the account—that is, the part earned during the marriage. The participant’s earnings history and account statements are essential when determining how much of the account balance qualifies as marital property.
You’ll also need to deal with employer contributions. These often come with vesting schedules, meaning the participant may not own them 100% right away. Only the vested portion may be divided in a QDRO. If your spouse has unvested benefits, those may be forfeited depending on the circumstances. A well-drafted QDRO will clarify which amounts are marital and which can be legally assigned.
