I'm in Texas. I recently did all the civil work for a subdivision. The land that the subdivision was built on came with a lifetime drainage easement for the adjacent property. My customer needed me to make improvements to that adjacent property in order to satisfy the easement for the subdivision that they just constructed. If he doesn't pay me for the work I did on the adjacent property, can I lien his subdivision or is my lien only valid on the actual property to which improvements were made, regardless of which property actually benefits from the improvements?
