Employee vs. Employer Contributions
A 401(k) plan like this includes contributions made by the employee (the plan participant) and potentially matching or additional contributions from the employer. Only the vested portion of employer contributions can be divided in divorce. If the participant hasn’t been with Montauk long enough to fully vest, the alternate payee may not be entitled to the full amount referenced in the account balance.
Your QDRO must reference the vested balance as of the date of divorce or another agreed-upon valuation date. It must also define whether future vesting after divorce will factor into the award.
