You are worrying about something now, which could perhaps wait until this nightmare of Coronaviris is over.
At the moment Government and the advice services are struggling to cope with the number of enquiries, at a time when half of their staff are self isolating.
Your situation may be much more normal than you think. You are living in a relatives house and when they die you will have to leave within a few months to find alternative housing.
Later in the year when things are hopefully back to normal, it might be advisable, to look at other housing options, so your husband, child and yourself move to your own rented property with a tenancy agreement. Then with the housing in yor name, you can include the housing on a Universal Credit Claim. The Council may be able to help with housing options in your area.
Use the benefits calculator to see whether you currently would be helped by claiming any benefits, even without housing at the moment, as you can't currently claim for that.
