1. Employee and Employer Contributions
401(k) balances can include employee contributions (which are always 100% vested) and employer contributions, which may be subject to a vesting schedule. If you divide the account based on a percentage of the total balance, it’s vital to clarify whether unvested employer contributions are included. Otherwise, the alternate payee could end up with less than expected—or the plan may reject the QDRO for ambiguity.
