Employee vs. Employer Contributions
In most 401(k) plans, contributions come from two sources: the employee and the employer. Employee contributions are usually 100% vested, meaning you own them outright. Employer contributions, however, might be subject to a vesting schedule. This is important in divorce cases because only the vested portion of the employer’s contributions can be divided in a QDRO.
If your QDRO doesn’t specify vested versus unvested contributions, you could accidentally assign an amount that simply isn’t available. That’s why working with qualified counsel matters—an experienced QDRO attorney will request the vesting schedule to make sure the allocation will actually be processed by the plan administrator.
