Chad Parker owned an acre of property and a mobile home on that property. He sold the mobile home to David and Allison Wilson for $1,000 and sold the property to them for $10,000. These agreements were made orally. No title or deed transfers took place. The Wilsons lived in the mobile home for seven years, making

$11,228.19 of improvements to the structure and to the property. After a falling out between Chad and David, Chad had the Wilsons evicted and moved back into the mobile home. Because there was no written contract between the parties, could Chad therefore legally evict the Wilsons and legally move back into the mobile home?
