Husband's mom is being kicked out of her nursing home

My SIL was paying for my MILs nursing home but they had a fight and my SIL is refusing to keep paying so she's being kicked out. We've been getting calls from the nursing home to come and get her. She has 7 kids and none of them my husband included, talk to her. My SIL did but she fucked that up. My husband doesn't want to take his mother in. They keep calling. What happens if no one takes in the elderly person being kicked out?
