1. Employee and Employer Contributions
Plan participants typically contribute through payroll deductions. Employers often match some portion of those contributions. One of the most important questions in your QDRO is which portions are being divided—just employee contributions, or employer matches too?
Another layer: employer contribution vesting schedules. If only part of the employer match is vested at divorce, a QDRO can only divide the vested portion. An unvested portion may be lost unless the QDRO includes what happens to future vesting.
