I was a practicing lawyer 10 years ago but now am retired. 10 years ago a man was a defaulter in a bank. He used my services to get the part of the loan amount and the interest written off/pardoned. He did not pay me any fees that time. He had also taken money from several other people and had fled India and gone to USA. Now he is visiting India and i have come to know that he had paid money back to a lot of other people but he has not paid my fees till now. I do not have any written proof that he used my services and did not pay. What legal action can i take to recover my money. He is not an indian citizen any more.
