In over his head.
Mahaney has a specialty. DUI and traffic court. He has much experience in this area. Beyond that I would recommend finding an experienced attorney. In my case he had little specific knowledge to apply to my case and actually misfiled important documents. Leaving me little room for appeal.
Patrick Mahaney
Replied last March 28, 2014The former client who posted this diatribe is a convicted sex offender, convicted in an out of state court, who did not want to be subjected to the Alabama Sex Offender Registry. This individual actually had a good legal defense in that the act complained of took place out of state, and under Alabama law, would not have been a criminal offense. Our theory of the case was that an act that was not an offense under Alabama law could not be the basis for registration as a "sex offender" under Alabama law. I allowed the client to make a 50% 'down-payment' on the legal services contract with the written agreement that the balance was to be paid in 30 days. At that point, I conducted detailed legal research and filed an extensive brief with the Administrative Law Judge responsible for hearing the contest to the registration requirement. The hearing then proceeded as scheduled. In the meantime, thirty days passed without payment, then sixty days passed, and after two written demand letters and two telephone calls to request payment, the client stated that he was unable to pay, I then filed for withdrawal and provided the client his file. The fact is the client breached the terms of the legal services contract and did not pay for his legal services. There is no truth to the claim that I "misfiled" important documents.
