Can't get out with the kids
My sister is planning to leave her husband after 8 and a half years because he is irresponsible and a bad father. They have four young children. He told her she can leave whenever she likes (i.e. he's DONE with her) but she cannot, what-so-ever take the kids with her. She fears he'll take them and she'll never see/be able to find them ever again. She's in Texas, and it's a common law marriage. He slapped her across the face (only once she says) nine months ago and was neglectful of her health by not making sure she received prenatal care during and after all four of her pregnancies and labors (they use midwives rather than an OBGYN). They don't use birth control and can't afford the kids they have now, let alone any more. She wants to come "back home" for a while until she gets on her feet. We don't want to get involved because we can't be sure he won't get violent and come after us. Otherwise we'd let her come here. She has no money or car of her own, and is afraid to seek help online or from neighbors, least he find out. She hasn't any friends in TX, he won't let her have any. He doesn't want to hold down a job and support his family, he'd rather wander the country trying to start his own church. He takes them with him and they are forced to sleep in parking lots in their car, the children suffer greatly when these excursions occur. She needs help and to get away from him, pronto. Is there any way she can leagally get away from him with the kids?
