My question involves criminal law for the state of: MD
I was charged with a crime: Talked to a friend who said his friend is a lawyer and he could help me out. Received an e-mail from the lawyer (friend of a friend) he asked what happened, and I explained it in one e-mail. He replied that he was licensed in a different state and could not help me, but he would recomend me to someone, in this e-mail he stated his rate is 350$ an hour, and he had spent .5 hours on the two e-mails thus far. I replied, that was fine and I would appreciate his referral services.
Next e-mail I received from him was a referral for a lawyer in the state which I was charged, and a couple scanned pages out of CFR's quoting some of the laws and repercussions for my charge. I thanked him and contacted the lawyer he recomended.
Couple weeks later I get a bill for 817$. 1 hour of his time at 350$ and 3 hours of his paralegal at 150$/hr for the research.
Now I have already hired and paid the lawyer he recomended who did the same research the first lawyers paralegal did.
I accept the fact that I owe him 350$ per his bill for his 1 hour as we agreed to, what I do not think I owe him for is a couple scanned pages from his paralegal which we did not agree to and I already paid the lawyer handling the case for.
My plan is not to pay him above the 350$ which we agreed on, but what are the consequences? Does he have any right to charge me for services which I did not request and did not agree to?
