Do you have different tax laws in each state? In my country, for example, the activity of a lawyer is licensed and controlled by the Bar Association, in which he will then work. If you need help in another region, the board will find a lawyer.
At the first stage, as a rule, telephone conversations or correspondence via mail are required. Any lawyer can do this, the main thing is that he has experience in such cases.
It is he who should contact the bank, sort out the problem and offer options.
