Employee and Employer Contributions
401(k) plans like this one include salary deferrals made by the employee and often matching or discretionary contributions from the employer. One of the first things to identify in your QDRO is which contributions are being divided. Will the alternate payee receive a share of just the employee contributions? Or will they also receive the vested portion of the employer match?
This is especially important when dealing with a plan sponsored by “Unknown sponsor,” where access to plan-specific rules and vested benefits may require direct communication with the plan administrator.
