The kids in my neighborhood are always playing in my yard and in the street unsupervised. A child left his tricycle in my driveway completely unattended. I moved it to the street by the curb so my husband could get his car into the garage and in the process of lifting the tricycle, a few parts fell off. I put the parts next to the tricycle and went into my house to get my son out of the car. By the time I went back outside to move the tricycle back to the sidewalk, the child's father was coming to my door threatening to sue me for the cost of the tricycle as the neighborhood kids told him I threw it out of anger. I am wondering what are my rights as the owner of my house and what are the neighbor's rights regarding items left on my property? Is there a legal way to stop the neighborhood children from using my front yard? The parents are never visible to monitor their children. I live in CA if that makes a difference.
