The rights granted by Sections 12-45-140 and 12-45-150 shall exist after property has been advertised for sale under tax execution if the applicant shall also pay the prorata cost of the advertisement and in any such case the sale shall continue as to the remaining property. When the segregation and payment of taxes as segregated are made after the tax has gone into execution and before advertisement, the officer charged with the enforcement of the execution shall return it to the treasurer or officer issuing it and thereupon the treasurer or other officer shall receive the old execution and give credit for the entire amount of the taxes represented thereby and shall issue a new execution against the property specified in the old execution upon which the tax has not been paid and charge the sheriff or other officer charged with the enforcement thereof with the amount of the new execution, which shall be the unpaid portion of the old execution, and no additional costs shall be allowed by reason of the issuance of the new execution.
