I would like to loan my partner an amount of money to purchase the business of a bar, which will then be leased. He owns his apartment which has 10 years remaining on the mortgage. I want to be sure that my money will be returned if anything happens to him. He is 64 years old and has two sons. Is there a way to ensure repayment of money in such an instance. The two different options which I have currently been offered don't seem to be viable. Thank you
