That does not matter as lawyers do not charge upfront for any case. Meet a lawyer and inform him about your existing financial issue and do inform him that you can pay him as soon as your account gets unfreeze. Some of them do it without hesitation but they might charge you more which is okay if you can get access to those funds in the frozen bank account. Writing here and discussing the issue will not help you as without a lawyer you will lose all that you have in the account. Another important thing if you do approach a lawyer and get your account back then ensure you file your taxes as this issue will be reported to the income tax department.
