A person shall not be summoned as a trustee, unless at the time of the service of the writ he or she resides in the State. However, debts due and owing from a person resident outside the State, or from a number of persons, part or all of whom reside outside the State, having an authorized agent resident in the State, may be attached and holden by trustee process. Service of such process upon such agent as provided for in service of writs of summons, shall be sufficient notice to such trustees as reside outside the State.
