Want to adopt my best friend's baby..help

My friend is pregnant and scheduled an abortion but after thinking about it, she decided to ask me if I want the baby because she knows my partner and I just lost a baby because I had an ectopic pregnancy. I am wondering if anyone is familiar with this, do you know how difficult this might be for me? I know the main thing I need to do is contact a lawyer (which I did) but I just am curious if this is a difficult process, even though the birth mother wants me to take her baby.
