Employee Contributions vs. Employer Contributions
The Monarch Metal, Inc.. 401(k) Plan likely includes both types of contributions. Employee contributions are always 100% vested—they belong entirely to the plan participant. Employer contributions, however, may be subject to a vesting schedule.
In a QDRO, only vested employer contributions are divisible. For example, if a participant has been with Monarch metal, Inc.. 401(k) plan for three years and the plan has a six-year vesting schedule, only a portion of the employer contributions will be available to divide. Always verify the vesting status before calculating the marital share.
