Proceeds of sale from marital property

Hello

Long story short, I am getting divorced, and we are splitting the house. Once its all done and dusted I will have around £85,000.

If I put this into a Instant-access savings account, does this count as capital? I was told proceeds from property do not count.

The reason I ask is I am going to have to support 4 children and rent a property, will I still be entitled to housing benefit until I get myself sorted and settled and find a new job?

Thanks
