Extremely Unprofessional and Negligent Representation

Extremely Unprofessional and Negligent Representation If I could give zero stars, I would. This lawyer completely mishandled my stepsister’s divorce case from start to finish. He never answered the phone, ignored calls for weeks at a time, and often took two to three weeks to respond — if he respo...nded at all. Even when he did, his communication was vague, dismissive, and provided no real guidance or updates. Because of his gross negligence, my stepsister lost her right to alimony, lost child support, and even lost primary custody of her children. To make matters worse, he failed to object or respond to critical terms in the divorce decree. The final decree was issued without her being properly informed, and it felt as if her own attorney was working for the opposing side instead of defending her rights. This so-called “representation” caused devastating emotional and financial harm. No client deserves to be ignored, misled, and left unprotected like this. Avoid this lawyer at all costs — he is unreliable, unresponsive, and dangerously careless with serious legal matters.

updated on 06/12/2017

Stayed suspension means the attorney has been suspended, but that the suspension is placed on hold (and ultimately removed) if the attorney complies with certain requirements.
