“and im just wondering what the people in law school do for money if they are married “
The same as anyone who isn’t employed (for whatever reason) who is married. Relatives can support you. You can borrow money. You can work full time and go to school part time (which is not an option at elite law schools, but is an option at the rest). You have the same issues as anyone who gets married before they are self-supporting (hardly a rare instance).
