Family is family and business is business. Don't confuse the two. If you want the farm and are investing time and money into the farm then get it in writing. If your dad is unwilling to do this then invest your time and money into something less risky. It is you fathers property and it is his to do with as he wishes. Make the smart business decision and do not rely on promises or hopes.
