Legal life line

my mother and father have been together for over 30 years in 2004 my father was in an accident that left him with a brain injury. The brain injury left him violent angry and abusive and for the last 14 years she has cared for and supported him. the last few years the abuse has been horrible to watch but she recently found out after a family member had died before christmas, my father cheated on my mother with a friend of hers she has since moved in with me and my girlfriend so that she can try to move on and be free of the abuse. the reason i am trying to raise money now it to help pay for a lawyer and my father has all the credit cards so she has no money to deal with the divorce and make a fresh start were not sure what the costs will be but hopefully this go fund me will help her on the way to getting a fresh start
