Avvo.com is a service for U.S. attorneys to answer questions about U.S. law.
"Patta land", at least according to my Google search/*, is restricted to Indian law (the subcontinent, not Native Americans). Consult with an attorney in India.

"Patta" is a document which shows the ownership of the property, and "patta land" is land that comes with such documents showing your ownership. As the attorney above indicated you should consult with a lawyer proficient in Indian land-use or real-estate land to identify the documents necessary to secure your ownership and to walk you through the process.
