Responsibility - Any person
who owns or controls an MSB is responsible for registering the business.
If more than one person owns or controls the MSB, the owning or
controlling persons may enter into an agreement designating one
of them to register the business. The failure of the designated
person to register the MSB, however, does not relieve any of the
other persons who own or control the business of the liability for
the failure to register the MSB.
