A Patent Survey is the very first survey of a piece of land done at the time the first
owner of the property is given title to it. Most patent surveys consist of a deed from
the State to the property owner. In this area however many of our patent surveys were
issued as grants from the government of Mexico or the local Empresario or from the
Republic of Texas. Although these documents are often nearly 200 years old they are
the legal title on which all future titles to the land are based.
There are over 550 patent surveys in Gonzales County Texas.
