What is your opinion on my working as a lawyer, where I appear before the civil courts in order to defend civil and commercial cases in which there may be riba involved?
He replied:
http://www.islam-qa.com/en/ref/75613/lawyerUndoubtedly there is nothing wrong with one person acting on behalf of another in cases of dispute, but it depends on the type of dispute:
1. If the case is well founded and the representative is basing his case on facts that he knows, and there is no perjury, lying or trickery involved, and he is representing the person in order to present his proof and evidence as to the truth of his claim or to defend him, there is nothing wrong with that.
2. But if the dispute involves some false claim or speaking on behalf of someone who is in the wrong, then this is not permissible.
