Employee Contributions vs. Employer Contributions
This plan likely includes both employee deferrals (contributions the employee made directly from paychecks) and employer match or profit-sharing contributions. In a QDRO, it’s critical to specify that the awarded portion includes both types of contributions—unless the parties agree otherwise.
Also, be aware that employer contributions may be subject to a vesting schedule. That means an employee may not “own” the entire employer match unless they’ve worked there long enough. If you’re dividing the account at divorce, only the vested balance should be divided in most cases.
