Would a letter you send while purporting to represent the debtor, in which you lie about your identity, potentially be introduced in court? Anything's possible.
As jk said, that statement made no sense.
If they think you're not a lawyer, they would want your friend's permission to speak with you about her case (or would simply end the discussion). If they think you are a lawyer, they would want your permission to speak to your friend.
Perhaps you intentionally created the impression that you were a lawyer, and what you mean is that they want confirmation that you are, in fact, a lawyer who is authorized to participate in the legal proceedings?
The question seems to be "Can I get away with lying about my name, and will the debtor's position be hurt if I'm caught lying." Maybe and maybe, with the better answer being "Nobody here is going to tell you to lie."
If somebody calls the creditor and gives their real name, is clear that they're not a lawyer, and says "I want to negotiate for my good friend Sally," that would not be unauthorized practice of law, although it would likely be a short conversation. If that person calls the creditor and claims to be a lawyer, or uses a name or description implying that he is a lawyer, under Florida's statute that's unauthorized practice of law.
They don't lie about who they are and, if it's not a lawyer calling on behalf of the debt negotiation company, they don't pretend to be lawyers.Quoting Florida Statutes, Sec. 454.23. Penalties.
Nobody here is going to tell you to lie, let alone tell you that there won't be consequences for you or for the debtor if you're caught lying. You apparently believe you have a reason to lie, or stand to benefit from lying, so it's also reasonable to infer that there's more to your plan than you've shared with us.Quoting oldmanintheshoe
