Foreclosure Process:

The Treasurer files the Certificate of Delinquency in Superior Court. Title reports are ordered, and all parties with recorded legal interest as found in the title searches are served with notice and summons by certified mail. The Treasurer receives a judgment from the Superior Court for foreclosure on tax liens and authorizing the sale of parcels. The pleadings are published in the local newspaper, listing all parcel information. Foreclosure costs and fees accrue during the entire process.

Any property in the process of foreclosure may be redeemed by their owner(s), or other parties with recorded legal interest, until the close-of-business the day prior to the sale date, by paying the entire amount due to remove it from the sale.


The Treasurer offers the parcels on a ‘where is’ and ‘as is’ basis. The County makes no representation of warranty, express or implied, as to the condition of title to any property nor the physical condition of any property or its fitness for any use or purpose.”

The county makes NO guarantees whatsoever on parcels sold at Treasurers’ sales. It is important that you do research on all potential purchases prior to the day of the sale.
