1. Employee and Employer Contributions
Most 401(k) accounts contain both employee contributions (money the employee chooses to put in) and employer contributions (matching or profit-sharing deposits). Only the amounts contributed during the marriage—and any investment growth—are considered marital assets in most states.
In many cases, employee contributions are immediately vested, but employer contributions may be subject to a vesting schedule. Understanding those vesting rules is crucial to defining what portion of the total account your QDRO should allocate.
