About 12 yrs ago I put up temperary horse panels on my neighbors property. These panels are 16ft long and go the entire acre of his property. My house is located a property away. I put and wired the panels up against the existing old rotten fence with the understanding that should the neighbor sell the property I would be able to take the panels with me. The neighbor next door thinks that the panels are his (he bought that place a year ago and said that the panels between the two properties are owned by him now. What legal rights do I have to take them? I have all the receipts and witnesses from years back who I paid to help me put them up.
