1. Employee vs. Employer Contributions
Most 401(k) plans include both employee and employer contributions. While employee contributions are always 100% vested, employer contributions may be subject to a vesting schedule. This matters because only vested funds can be divided through a QDRO.
If your divorce occurs before your spouse is fully vested, you may receive a smaller share. Unvested employer contributions may revert to the plan when the participant leaves the company.
