If you’re a closely held business or not, changes do happen. Whether it’s leadership or who serves as your plan’s trustee, change will likely happen. The problem sometimes is when the plan document has been updated to reflect who the current trustees are, yet the plan custodian doesn’t. That could certainly be a problem if one of the trustees left on acrimonious terms and wants to go to business for themselves and take a distribution that they weren’t entitled to.
So if you make a change of trustees, also make sure that your third party administrator and plan custodian know as well, so the records and signings cards are updated. Otherwise, an unhappy trustee may think it’s a 401(k) version of Supermarket Sweep.
