Reply To: Single dad in SW has a question or two
Unless you have shared care you cannot really justify receiving the child benefit without her agreement. And CB is the gateway benefit you need to claim uc.
So you have two options, get her to agree to you claiming CB. Or increase your over ifhts to seven so you can justify making a counterclaim to the child benefit.
If she will receive any equity from the sale of the house between 5-16k she will lose some uc over 16k she will lose it all, so you could come to some agreement where you pay the equity back in smaller amounts if she wishes to rent so she can claim still and you also. But I’ve no idea if this meets the requirements for uc, but maybe worth exploring.
