If you wish to fight the eviction, you should hire a lawyer who specializes in landlord tenant issues and file the answer as required.
This answer does not establish an attorney client relationship and is just my opinion based upon the limited facts presented.
I am confused, you want to fight to stay at a place where you are be assaulted by other tenants? I would suggest that you try to work with the LL to simply let you out of the lease and move somewhere safe for you and your child. Though you can defend the eviction, it sounds like the consensus of other tenants and LL is against you, and this may prove a problem for you in court. While you have the right to be heard, there is no corresponding right to have the court agree with you and hiring a lawyer could be fairly expensive in this instance if local legal aid will not represent you.
