Don't do it. The loans you will likely have to take out will far exceed what the market will pay you in your first 5-10 years of working. About 5 years ago, when the economy first started going really down, law school applications tripled as no one was able to find work with just an undergrad degree. As a result, class sizes grew astronomically and there are now more law students than lawyers! This means the job market is completely oversaturated and just finding a job that pays something is hard for most. Very few get the cushy jobs. And...its just getting worse. I graduated top 5, with law review, a published article, and an appellate court clerkship and I had to resort to a dinky small firm to make ends meet. Thankfully I had a full ride, so loans aren't an issue.
On the other hand, my fiance is graduating this year and has loans whose repayment amount is going to be more than our mortgage. If she can find a job at all in the current market, it won't pay enough to pay her minimum monthly amount.
More to the point, law school for me was easy, for her its difficult. Depends on your ability to think logically and problem solve. The bar exam is an endurance test and was easily passable for me (I passed 2 different states my first year out), but for her I think she may not have such an easy time.
Just for a point of reference, I went to a state school undergrad, she went to ivy league school. I did poorly undergrad, she did great. There is no predicting factor.
