<human>: Throwaway account and cross posted on r/relationships
Background
We (30sMF) have been married a little over a year.  This is both of  ours second marriage and I have a daughter with my ex-husband, whom I pretty much have full custody of.

A couple of hours ago my husband was served with court papers for a paternity test and for child support for a 2 year old girl.  I had no idea that he could've been the father of any child. He has never mentioned anything to me even though he knows about the child,  He isn't sure if the girl is his and there is no name on the birth certificate under father.  

The mother (24F), I'm not sure how long they had a relationship for but it was before we ever met, is going for all medical expenses since the child was born, child support of course, wants him to get a life insurance policy on him for the girl in case he passes away, also health and dental insurance.  I am upset that he didn't tell me about the possibility of him fathering a child, I'm sure I will get over it, but I am also freaking out a bit that we are now just starting to get settled in life, buying a house and if he is the father I hope the mother will give him some type of custody and not just take us for all our money.  Is it possible for her to get all of that of if he is the father??  
We will be getting a lawyer as soon as we can.

Can you provide a brief overview of the text?
<bot>: SO might have a daughter with someone before we ever met, but she seems to be taking us for all we have.
