1. Employee vs. Employer Contributions
Employee contributions to a 401(k) are always fully vested. This means if your spouse contributed 10% of their salary to the Inter-entity 401(k) Plan over the course of the marriage, that portion is eligible for division through a QDRO.
Employer contributions, on the other hand, often vest over time. If your spouse has not yet met the vesting schedule for all or some of the employer contributions, those unvested amounts may not be available to divide. It’s critical that your QDRO clearly states how partially vested balances should be handled and whether future vesting applies post-divorce.
