[Amended 3-20-1990 by Bill No. 381]
Subject to the provisions of Md. Code Ann., Tax-Property Art., Title 13, Subtitles 1 and 4, a tax is hereby imposed upon every instrument of writing conveying title to or an interest in real property offered for record and recorded in Talbot County with the Clerk of the Circuit Court, for all or only that portion which is actually located in Talbot County, provided that conveyances by or to the United States, the State of Maryland, or any political subdivision of the state shall not be subject to the tax imposed by this section. The term "instrument of writing," as used in this article, shall be deemed to include any deed, lease, assignment of leasehold property or any other device the purpose of which is to convey title to real property, but shall not include any mortgage, deed of trust, conditional sales contract or any other device the purpose of which is to afford a security in real property rather than to convey title thereto.
