I've recently purchased a property that is adjacent to our neighbors who paid for a boundary fence located on property line prior to my purchase. The neighbor is now claiming that I'm responsible for half of the cost of the fence since I'm erecting a gate to enclose my property under state law. My gate will not be attached the property fence although from my understand since it's on the property line is have duty for maintenance and therefore can connect the my side of the fence. I've looked up the rcw related to fences which is RCW 16.20 Fences. This RCW is under Title 16: Animals and Livestock. It appears that the rcw is ralated to agricultural fencing for enclosing livestock utilizing neighbors fence. Please advise.
