43. Where a certificate-debtor dies before the certificate has been fully satisfied, the Certificate-officer may, after serving upon the legal representative of the deceased a notice in the prescribed form, proceed to execute the certificate against such legal representative; and the provisions of this Act shall apply as if such legal representative were the certificate-debtor and as if such notice were a notice under section 7:Provided that where the certificate is executed against such legal representative, he shall be liable only to the extent of the property of the deceased which has come to his hands and has not been duly disposed of; and, for the purpose of ascertaining such liability, the Certificate-officer executing the certificate may, of his own motion or on the application of the certificate-holder, compel such legal representative to produce such accounts as the Certificate-officer thinks fit.
