I’ve been with my partner for ten years and we have 3 children. We’re not married, as firstly I don’t believe in it, and secondly he had a historical gambling problem and we decided many years ago to ensure he had no access to our savings. He works, but I earn 4x more and all assets (car, house) and savings are just in my name - he transfers me money from his salary each month. How can I prepare that if I were to die suddenly he gets access to my money to keep paying the bills? I have a will which leaves everything to our children but I don’t know in practise how he would quickly access money that he would need.
