Employee vs. Employer Contributions
Most 401(k) plans include both employee contributions (what the worker puts in) and employer contributions (company match). These may be subject to different vesting rules, especially regarding whether the employer contributions are marital property. Generally, only amounts earned during the marriage are subject to division.
It’s important that your QDRO clearly states whether it includes just the employee contributions, the employer contributions, or both. Be sure to find out the full balance, including any employer matches, as of your marital cut-off date.
