Not sure but here in Texas you register / post your No Trespassing with the Sheriff’s Dept you only have to call them once on a trespasser. The Sheriff’s Dept will “remove” them and book the individual. After that if they catch them on your property it is straight to jail for them, no questions no options. You don’t even need to call or be there. Other State are probably similar. Kind handy when one is busy “wiping their nose.”
In Tennessee, the TCA says the property needs to be reasonably posted at points of ingress and egress. If a person ignores the no trespassing sign and is caught it becomes criminal trespass. No registration with the Sheriff is necessary. Had to prove that one about a year ago to a couple of guys who thought it would be okay to fly powered paragliders from my private grass strip without my permission. Big mistake on their part....
I thought in Texas all private land was posted even without a sign.
