Dividing Employee and Employer Contributions
Employee contributions and their investment growth are always 100% vested and typically divisible based on the marriage period. Employer contributions, however, may not be fully vested. The QDRO must specify whether only vested accounts are divided or whether forfeited (non-vested) employer contributions should be included in the calculation.
In most 401(k) QDROs, the alternate payee receives their share based on a date-of-marriage through date-of-separation formula, using the account balances and any applicable gains or losses. Be specific—general percentages without dates can lead to significant confusion or delay during processing.
