I lent money to a business partner nearly 3 years ago when he was in a bit of financial trouble. It wat not a massive amount, so I did not press him for the money. He recently won a big contract and I know things are going better with his business. When I asked him to pay back my loan, he refused and said that my claim had prescribed so there was nothing I could do and he was not going to pay it back. Surely this cannot be the case?
