Someone asked me to find out about a particular lawyer in New YOrk. How can I check
On a lawyer. I know how to check on doctors but not lawyers... i.e. complaints
Against them, their education, etc.

Check with the state bar

NYSBA | Home (http://www.nysba.org/)

Or you could call up your local County Bar Association as well and ask them.

Go to the New York State Courts web site to check registration status.

Google them or their firm.
