Employee and Employer Contribution Divisions
401(k) plans are often funded by both the employee and employer. Contributions made by the employee are usually fully owned when contributed, but employer contributions may be subject to a vesting schedule. This matters when drafting a QDRO—only the vested portion of employer contributions can be allocated to the former spouse (alternate payee).
The QDRO can divide only the amounts earned during the marriage. That usually means the marital portion will be divided either by a specific dollar amount or a percentage of the vested account balance as of the date of separation or divorce.
