If there is a claim you should attempt to look into both his and your closing documentation. There may have been documentation signed by former owners noting that the former owner of his home acknowledging that the former owner knew that the fence was encroaching on your property. The document may also contain a waiver of the right to make an adverse possession claim on the space (to avoid the need to remove the fence to a proper location). Such documents are required by title insurance companies upon real estate transfers.
