When the personal estate of a decedent is insufficient for the payment of his debts, his executor or administrator may commence and prosecute a suit in equity to subject his real estate to the payment thereof as provided in this article. The surviving wife or husband, heirs and devisees, if any, and all the known creditors of the decedent, shall be made defendants in such suit. If such suit be not brought within six months after the qualification of such executor or administrator, any creditor of such decedent, whether he has obtained a judgment at law for his claims or not, may institute and prosecute such suit on behalf of himself and the other creditors of such decedent, in which the personal representative, surviving wife or husband, heirs and devisees, if any, of the decedent shall be made defendants. If any creditors’ suit shall have been brought against the decedent in his lifetime, and be undisposed of at the time of the death of the decedent, a separate suit shall not be instituted by any other creditor, nor by the executor or administrator, but the plaintiff shall, or, if he fails to do so within six months after the qualification of the executor or administrator, such executor or administrator or any general creditor, by intervening, may, in the suit already pending, by amended and supplemental bill, cause all proper and necessary parties to be brought into such suit; and thenceforth the same shall proceed as a suit instituted under this section. In every suit under this section anyone claiming to be a creditor of the decedent, whether he may have been made a party thereto or not, or whether he may have been served with process therein or not, may present his claim, and, upon such presentation, shall be deemed to have been made a party to the suit and to have been served with process therein. And evidence respecting such claim may be taken, and the same may be allowed and paid, in whole or in part, or rejected in the same manner and with the same effect, as if such claimant had been originally made a party and served with process.
