Employee and Employer Contributions
One part of your QDRO will address how to divide the contributions made by both the employee (usually through salary deferrals) and the employer. Often, only the portion accumulated during the marriage is subject to division. Establishing the marital portion will often require a date-of-marriage to date-of-separation analysis and may need account statements from those timeframes.
Employer contributions might be subject to a vesting schedule. This means some of the balance accrued during the marriage may not yet “belong” to the employee and could be forfeited if they leave their job too soon. The QDRO needs to address how to deal with both vested and unvested amounts.
