Employee vs. Employer Contributions
Employee contributions are always considered 100% vested and part of the marital property if contributed during the marriage. However, employer contributions can be subject to a vesting schedule. You’ll need to determine what portion of employer contributions were vested as of the date of divorce or agreed-upon division date.
Any unvested employer match or profit-sharing funds are usually forfeited after divorce, unless the employee continues working and becomes vested. Your QDRO should address how to treat unvested contributions.
