Boalt is a great school for married couples. They have a family housing complex that is away from campus - a quiet place full of young kids. Spouses have tons of job opportunities in SF, which is a quick BART ride away.
And if you have kids, there is a very supportive network of parents that help each other get through. The administration even will try to schedule your classes so that you can minimize your time on campus and get home. And there is day care on campus at which you can drop your kids off.
Also, the non-competitive atmosphere makes it very friendly to people who would like to have a balanced life and actually spend time with their spouse and kids.
