I made a new claim for housing benefit (not universal credit) i declared my sons savings, he has £2000 in an account that can be withdrawn i'm the trustee of it and i have savings of £3000. my son also has a child trust fund the government set up and i know that won't affect the claim. I read online that his accessible account can have 3k limit before it affect my claim, why 3k and what would happen if it goes over?
