1. Employee vs. Employer Contributions
One major issue is how to handle the different contribution sources. This plan likely includes both employee deferrals (your ex’s paycheck contributions) and employer matching or prevailing wage contributions.
Usually, QDROs divide the entire balance as of a specific date, but it’s important the order clearly state whether the alternate payee is entitled to both employee and employer contributions. In some cases, unvested employer contributions may not be dividable.
