Annuity Immediate Quote

*I’m asking this on behalf of someone else who needs advice. If it makes a difference, this is in Canada.

My bf’s mom and dad have been having marital troubles. The husband moved out once and left them already, and threatened to stop supplying money for groceries, quit making car payments and sell the home. He left voluntarily, by the way. He works, she doesn’t because she had an accident a few years ago leaving her having trouble walking and panic / anxiety attacks at the drop of a hat. About a month ago he moved back in because he didn’t enjoy not having cash to spend whenever he wanted since it was going toward his kids and rent. He couldn’t handle the single life, basically.

Now he’s moving out again the end of this month. He said to her “I’m leaving. Don’t bother getting the pool or anything set up and don’t bother gardening. You won’t be able to keep the house or the car so you either sell it or it all goes to hell. The kids can live with you, I’m done”.

Now, if I’m not mistaken – if he voluntarily leaves and they divorce or whatever, wouldn’t he have to pay alimony and child support on top of that ? So then wouldn’t she be able to keep the home ? It’s not a large home – 3br 2ba and it’s only a 1 story home. What options does she have ? Her oldest son is 18 so child support wouldn’t go toward him, but she has also has a 15yr old.
the home is in both of their names.
