Employee and Employer Contributions
401(k) plans are made up of both employee deferrals (what your spouse put in from their paycheck) and employer contributions (matches or discretionary contributions from the company). In most divorces, each side needs to determine how much of the account balance is marital property. The QDRO should specify whether both components are included in the alternate payee’s share.
Be aware: many employer contributions are subject to a vesting schedule, meaning your spouse may not fully own all the funds listed in the account. If a portion is unvested at the time of divorce, those amounts may be forfeited later—something that must be addressed in the QDRO language to prevent disputes down the line.
