I was informed by a lawyer, you don’t have to let CPS in your and you should never let them in, without a warrant. Never talk to them or let your children talk to them. Every case is different, but in my opinion he is right. The lawyer told me that’s how they get a warrant, by rewording what is said and what they see. If you have not done anything wrong do not sign anything giving up any of your rights. If you have abused your children, it is a criminal matter and will be settled in criminal court.
