Employee and Employer Contributions
The plan likely includes employee deferrals (the amount the employee chooses to contribute from each paycheck) and employer matching or profit-sharing contributions. A QDRO can divide just marital contributions, or the entire balance including post-separation contributions, depending on the divorce judgment.
Employer contributions are subject to vesting. That means only a portion may be considered “yours” at the time of divorce. The unvested portion isn’t divisible unless and until it vests, which may or may not occur post-divorce. The QDRO should clearly define whether only vested amounts or both vested and unvested balances are included.
