1. Employee vs. Employer Contributions
Most 401(k) plans like this one include both employee deferrals (what the participant contributes from their paycheck) and employer contributions (such as matching or profit-sharing). The QDRO needs to specify whether the calculation includes just employee contributions or both employee and employer dollars.
Unless otherwise agreed in a divorce settlement, QDROs often divide the entire account as of a specific date. But watch for differences in vesting—employer contributions may be partially or fully unvested.
