If a bet was made on behalf of a number of people, on my online betting account, and I later had a falling out with these people and decided to close the betting account with funds still pending, am I liable to pay back whatever the winnings would have been out of my own pocket? Nothing was agreed in writing, but there may be up to 6 people who are willing to say they were present at the time. Some of the money was transferred into my bank directly, and the remainder was given in cash. I have attempted to make contact and explain that I had closed the account and even offered to pay the initial stake but after a few aggressive threats on the phone, I retracted my offer and haven't been in contact since. What is the likelihood of his case against me being successful?
