Free Divorce Record Search

Where I can find free marriage or divorce?
I tried searching for hours on Google and Yahoo, but I can not find a free site. All I want to know is the name of the person, my mother married a while ago. As in 1990, but all sites require me to spend more than 40.00, which may or may not be the proper person. Can anyone help?
State what you are looking for, the information may be available online. You will need to know the state and county of your mother married and begin the vital records office. This office will be a database search may or may not have information about how you can ask for a small fee.
