1. Employer Contributions and Vesting
One of the first things we look at in 401(k) QDROs is how much of the account is vested. In plans like the Cumberland and East Bay Lp 401(k) Profit Sharing Plan & Trust, employer contributions may be subject to a vesting schedule—typically graded over several years. An alternate payee in a divorce is only entitled to the vested portion of the account unless the plan allows otherwise.
For example, if the employee spouse is 60% vested at the time of divorce, only that amount of the employer contributions can be divided unless full vesting is achieved prior to distribution. Be sure your QDRO specifies vesting terms clearly, especially if you’re dividing as of a specific past date.
