Non-Contentious Probate (Fees) Order 2018

I genuinely ask out of misunderstanding: surely the point about probate fees is that you have to pay them, whereas other cases in the courts are of a wholly different kind. This is a payment you have to make if there is to be probate. Would my noble friend agree that it would be odd if we had a fee for the registration of birth—which is also compulsory—that was connected with the amount of money that the person registering would be able to pay? It seems odd to call a fee something which is connected with the value of something you have to do. It is the having to do it which makes it different from any other court situation that I can think of.
