The first think I got from this statement is you had a client- lawyer realtionship. And he sent you a 22,000 TL receipt as a result of his service. The thing is if you had signed a document with him written this amount below, you have to pay this money to him. Other way if he has not got that kind of signed document from you ,he is only allowed to take the amount which is declared by the government as legal fees. In your company this may be only 600 ytl.
If he has found that kind of document signed below name of you just want from the court to be examined if it is from you or not. At the end of the court if it is from you you will lose apparently, but if it is not from you you can sue him for thedamages.
If you can proof his bad behaviours to you and your family with witnesses( threat , forgery) not only sue him but also complain about him to the Bar assosiation.
