Can I file a lien as a professional designer?

The Texas Property Code states that an architect, engineer, or surveyor who prepare plans or plats must have a written contract with the owner or the owner’s agent, trustee, or receiver in connection with the actual or proposed design, construction, or repair of improvements on real property or the location of the boundaries of real property can file lien on the property.
In other words, any designer who prepares plans or plats under or by virtue of a contract with someone other than the owner is not entitled to file a lien on a property.
