Cameron County Clerk – Cattle Brand Registration

Livestock Laws

Cameron County is a Closed Range County as a result of election held on November 5, 1946.

Throughout Texas history, ranging constraints on domesticated animals have been a source of argument and debate, even to the point of violence in the 19th century cattle range wars. Ranchers who had been used to allowing their livestock to freely graze over wide areas were confronted by farmers or smaller ranchers fencing off their property. Over the years, laws have been developed to provide local control over these restrictions and to create a process for dealing with stray animals.

Sale and Shipment of Livestock (AG Chapter 146)

If a person in this state sells or transfers a horse, mule, jack, jennet, ox, or head of cattle, the actual delivery of the animal must be accompanied by a written transfer to the purchaser from the vendor.  The written transfer must give the marks and brands of the animal and, if more than one animal is transferred, must give the number transferred.


Marks and Brands (AG Chapter 144)

Marks & Brands e-Form:   

Beginning August 30, 2011 the brand re-registration period will commence and a new Mark and Brand application, distributed by the Texas and Southwestern Cattle Raisers Association, will be required when registering or renewing cattle brands.  The effective date of this application will be from August 31, 2011 – August 31, 2021.  New Applicants can simply fill out the application which will be available at our office.  However if you already have a cattle brand registered, it is required to re-register this brand by February 2012 regardless of the time in which you originally filed your brand.  All renewals must be filed within the six month grace period extending from August 31, 2011 to February 29, 2012.  If brands are not renewed within this time period, owners risk losing ownership to that specific brand.

Texas ranchers are encouraged to re-register their cattle brands in order to guard against livestock theft.  Cattle branding is the best way to prevent livestock theft and provides an easy way to identify cattle through Texas and Southwestern Cattle Raisers Association (TSCRA) brand recording and retrieval system.  Currently, the database tracks more than 100,000 brands.
