Can a repo man drive over your neighbor yard and grass and move yard furnishing without their consent damaging grass to remove a neighbor car?

This could vary from state to state. When we obtained our licensing it clearly states that we cannot move any property to get to our Mark. Also, unless given consent by your neighbor they have all the right in the world to pursue the repossession company for trespassing charges and any property damage reparations. I would call the police (not 911) and have a police report made along with pictures of the grass and furniture move to help the case.
