Liens are filed at the county seat closest to the property against which the lien is perfected. There are about 3,300 counties in the U.S. This is probably why the the Treasury decided to invest in the banks to cover the bad mortages instead of buying the loans. This is also why the liberals in congress have their panties in a wad over foreclosures. They really are powerless to stop them as the foreclosure actions go on at a local level. 3,300 local levels!
