My ex wife's house was destroyed by and land slide in March 2019 . The land is still very unstable and the remains of house and shed are in a very dangerous and hazardous condition . I have informed the surrounding neighbours and relevant authorities of the clear and present danger of entering the property . She still has people in the community that insist on using the property as a through fare to save time walking to the public easement . Her insurance was paid out and public liability has finished and she is worried that these trespasses could injure themselves and sue her for damages .I have placed No Trespass signs on property and these are being disregarded . She is considering putting in cameras and taking the images to police ?? Should she get her lawyer to send the offenders a letter to reframe from trespassing . Any Ideas ..Thanks Dave
