Legal Demand Notice By Hired Lawyer.

Normally, clients are not paying after winning their cases as We have faced this situation in last 30 years.

Dear client I'm sorry to hear that but in this case you have to first of all replied to the legal notice stating that the amount discussed on your was 10000 and the person has no right to demand anything about that. Moreover you can file a complaint against him on that ground

First of all you need to legally reply to that notice and also observe on what basis he's demanding such a heavy amount. If the fees and all was settled at 10k then I don't think he must demand anything else. For more legal assistance I am just a call away.
