Good move to talk to this lawyer. You should write down your main points and have it ready because they will only talk to you for a short call or meeting in person. They won’t look up your divorce case unless you hire them and pay them a retainer. But they will give you information about where you stand legally and whether hiring them to help you now is worth it.

You shouldn’t call the lawyer you are using “your lawyer, our lawyer”. They are a lawyer but acting as a mediator. A mediator is supposed to be an impartial party not representing either of you. If you had your own lawyer, they would have told you not to even agree to use your husband’s friend as the mediator because they have a conflict of interest being his friend. IDK if they were unethical or broke the law in what happened with you. More important than that though, let this new lawyer help you with what you should be getting/giving in your divorce.
