I have done work on my son’s home in recent years to help make the place more livable. The expectation was that the money I put out along with the labor I payed for would be paid back when he and his wife could. I also loaned money’s for the purchase of a font end loader, small bull dozer ,one 650 dump truck ,a John Deer tractor , a Kenworth log truck with trailer. All these loans were made opened with no date for repayment but considered a loan. My desire here is to put this in legal terms to protect myself because his wife is filing for divorce and need to know I can get payed. Do I file a mechanic’s lien ?
