A representative to whom letters are issued on the estate of a nonresident decedent or ward by a court of competent jurisdiction of any other state, territory, country or the District of Columbia may collect and receive any personal estate in this State of the decedent or ward and remove it to the jurisdiction in which his letters are issued upon delivering to the person or corporation indebted to or holding the personal estate of the decedent or ward, the following: (a) an affidavit by the representative that to his knowledge no letters, which have been issued upon the petition of an heir, legatee or creditor of the decedent or kindred of the ward, are then outstanding on the estate in this State, no petition for letters by an heir, legatee or creditor of the decedent or kindred of the ward is pending on the estate in this State, and there are no creditors of the estate in this State, and (b) a copy of his letters certified within 60 days before the date of presentation. Upon payment or delivery of the assets, after receipt of the affidavit and certified copy, the person or corporation is released to the same extent as if the payment or delivery had been made to a legally qualified resident representative and is not required to see to the application or disposition of the property; but no payment or delivery may be made sooner than 30 days after decedent's death.
