Employee and Employer Contributions
The total balance in the 401(k) may include both employee deferrals (the portion the participant contributed) and employer contributions. Employer contributions are often subject to a vesting schedule. If part of the account includes unvested employer contributions, they may not be divisible, and that can significantly impact the marital portion. The QDRO should specify how to handle these distinctions, especially if you’re using a percentage-based division.
