Mum passed away with no will. where do I stand if dad is taking all her money?

Hello. My mum recently passed away with no will. Dad is giving me and my sister who are both adults £2000 from her savings whilst keeping £6000 for himself on top of that he is getting a £30,000 lump sum and wants to keep all of it. Mum believed in saving and wanted us to have money for the future and I know dad will just spend it all. I feel its un fair. Where do we stand legally? And how could we convice dad to be fair?
Thank you.
