1. Employee vs. Employer Contributions
401(k) plans typically include both employee deferrals and employer matching or profit-sharing contributions. One of the most important QDRO drafting points is specifying whether the division includes just the employee’s contributions (which are always 100% vested) or employer contributions as well.
Employer contributions may be subject to a vesting schedule, meaning the employee may not be entitled to the full balance unless they’ve worked for the company for a certain number of years. If you’re unaware of the vesting status, you could assign funds in the QDRO that don’t exist yet – and that will cause serious problems.
