Family Law

I am a professional IT manager who is looking into changing career so I don’t end up like so many great IT managers that just because they are old and a younger person with less salary can do the job, they are almost out of job or have a job but got salary cut. Trust me I have seen a lot of these cases around me so I was thinking to go back to school to practice law and make good money no matter how old I get, I’d still have a good job and a good salary. now … can someone tell me which one I would make more money? Family Law ( I live in L.A by the way) or Intellectual Property?
I heard the school I choose to go to matters for the Intellectual Property practice. I can’t leave L.A so what are my options?
I really need to know what is the minimum salary when I start my law career too cause I am walking away from a very good salary in IT mgmt so I need to make sure I think through this big change before doing anything. Much appreciated!
