Yes, if she's married to him and he's the father on the birth certificate, he has equal legal rights to the child. She needs to be working with a local domestic violence advocate to get paperwork filed for divorce, custody, and restraining orders as may be appropriate. Otherwise, she can expect that dad will use the child as a tool to continue to control her.
Remind her that HE doesn't get to decide these things. A JUDGE does. Without there being court orders to the contrary, she can pick that child up and leave right now. Dad can then ATTEMPT to file for custody and ask the court to order the child to be returned - which is why SHE needs to do the filing and get a court order in her favor BEFORE dad can do this.
If he's been kicking her out WITH the child, that alone will tell the court that he considers perfectly fit to care for the child, no matter what he wants to claim later. If mom has been the child's primary care giver, the court will need SUBSTANTIAL reason to change that, not just dad's opinion.
She needs to be aware that if there have been repeat instances of domestic violence, and she chooses to stay with or return to the abusive relationship, she risks child protective services getting involved and taking the child away from BOTH of them. The courts understand that ultimately adults are going to associate with whoever they want to, regardless of court orders - but the state won't knowingly stand by while mom returns the child to such an environment. The pattern of leaving and returning in abusive relationships is a common one - especially where there have been a lot of control issues where she may have difficulty in many areas, from securing housing, to getting and keeping a job in the midst of abuser antics, to money or credit problems - in short, LOTS of reasons why even women strongly determined to leave may end up returning. And of course "love". In order for leaving to be successful for the long term, these and other challenges need to be met, else returns will continue to happen - and each time it gives the abuser the ability to say "I told you that you couldn't survive without me". Nails in the coffin yanno.
