Neighbor's kids causing damage and trespassing in my yard
For about the last year, my neighbor's kids and their friends have been playing in our yard, hitting our home over and over with their toys and causing damage to one of our trees, a young maple tree, by breaking off the branches. I didn't say much when it first started happening because I didn't want to cause friction between us. It hasn't stopped, so within the last several months, I asked the kids to stop hitting our house, to leave our tree alone and asked them to go play in their own yard, and also talked to their mother several times. Nothing is working. The only response I get from the mother is "i'll do my best to keep them out of your yard", but she never does. I feel like both the mother and the kids are ignoring me. Any suggestions please, legal or otherwise?
