If the taxes assessed shall not be paid when due, and sufficient real and personal estate cannot be found on which to levy the same, the collector shall ascertain who are indebted to the person liable for the taxes, and shall make a list thereof, and advertise the indebtedness for sale at the courthouse door, giving five days’ notice in the manner prescribed for the sale of personal property distrained. He shall sell the indebtedness, of whatever kind, or so much as may be necessary to pay the taxes and costs, to the highest bidder, for cash, and make to the purchaser an assignment thereof. It shall be sufficient to describe the same, in general terms, as the indebtedness of the debtor to the party assessed for taxes, stating as near the amount as can be. Such sale and assignment shall vest the indebtedness in the purchaser, who shall be entitled to sue for and collect the same. If sufficient indebtedness cannot be found in his county to make the whole tax, the collector shall certify the whole or balance, as the case may be, to the collector of any other county where indebtedness may exist; and the collector receiving the certificate shall advertise and sell such indebtedness, and collect the taxes, with five percentum thereon, and pay over the tax, to the collector from whom the assessment was received. After the indebtedness shall have been advertised, it shall not be lawful for the owner thereof to sell, assign, collect, or compromise the same without paying the taxes. The tax collector may levy on the shares or interest of the delinquent taxpayer in any corporation, company, or partnership, and dispose of the same as if levied on under execution.
