Dividing Employee and Employer Contributions
Employee contributions to a 401(k) are always 100% vested. But employer contributions may be subject to a vesting schedule. For example, if the participant has worked only two years and the plan vests over five years, only a portion of the employer match will be available for division in the QDRO.
In a QDRO, you can specify that each party should receive a percentage of the “vested” balance as of a specific date. It’s important that the language limits distribution to vested contributions unless both parties agree otherwise.
