Employee vs. Employer Contributions
Contributions in 401(k) plans generally come from two sources: the employee and the employer. While employee dollars are always 100% vested, employer contributions often come with a vesting schedule. If a participant is not fully vested at the date of separation or divorce, the unvested portion may not be available to the alternate payee.
This raises an important QDRO drafting issue: Should the QDRO award a flat dollar amount or a percentage of the account “as of” a particular date? The best option depends on the vesting status and account valuation at the time of divorce.
