That’s actually an interesting one because if they do own the house, it’s a 50/50 split between Cath and Ian meaning Becki will automatically have the biggest legal claim to the house.she’ll use him to garner sympathy that’s about it.
Though I do wonder if the disgusting comments made about him have made her pea brain rethink using him for content.
She is Ian’s only biological child (and I can’t imagine this family bothering to go through the formal adoption process for Ian to be the other siblings’ legal father) so she will be entitled to his share of the house and then Cath’s share would be split 5 ways (Becki, 3 sisters, 1 brother) assuming there isn’t anything in the will (if they even have wills) excluding the sisters that are clearly estranged from the family.
So Becki would have like a 60% claim on the house in that case. And then if it’s a council house, she’d be entitled to it from being a tenant for so long if she’s paying a share of rent.
