How does Law School Financing work for T14?

Hi everyone:

I am a freshman at the University of Michigan (Out-of-state, paying nearly full tuition, but room/board will be partially/fully covered over the next three years), and I am interested in Law School. I have heard terrible things about financing for Law School. My family needs to send two more siblings to college (undergrad, and maybe even professional school afterwards), so I was wondering if Law School would even be financially feasible for me.

  1. How generous is financial aid at T14 Schools, especially compared to their undegrraduate programs?

  2. How does loan repayment work (I heard Law School Financial aid is much more loan-based than grant-based)?

  3. An unrelated question- to have good chances at admission, do I need to know what kind of Lawyer I want to be (Patent, International Law, Criminal Defense, Civil Rights, etc.), or is it common to decide that once you are in Law School?

Thanks!
