I live in California and one of my friend living in New Jersey asked me to send him some money to start a business 4 years back, I send him the money via bank transfer I do have the record for that, no business was initiated, on asking him to return the money he stats that all the money went into to business setup expenses, he never took any approval for initiating the expense, nor send me any documentation, neither chipped in his money. what should I do to recover the money.
