I was wondering if anyone had an opinion on an individual (i.e. Account Representative of a TPA) signing as plan administrator for a 3(16) defined contribution plan. I understand that under these circumstances that only the signature of the plan administrator is required. However, if the TPA is not a fiduciary for all aspects of the plan (i.e. payroll, personnel) but day to day functions (QDRO review, hardship approval) can the individual signing be open to personal liability should suit be brought against the plan sponsor and their fiduciaries? What does the IRS definition of being a 3(16) encompass? Should the employer still be required to sign as the plan sponsor?
