Employee and Employer Contributions
Most 401(k) plans include contributions from both the employee (elective salary deferrals) and some form of employer match or discretionary contribution. Your QDRO should specify whether the alternate payee (usually the former spouse) is receiving a portion of just the employee contributions, all contributions (including matching), or another defined share.
If your divorce Judgment says something like “half of what was earned during the marriage,” you’ll need to define that in terms of the actual account numbers and dates. It’s common to calculate the marital portion using data from plan statements or direct balance information from the plan administrator.
