Financial Control Legal Options

I was wondering. If i were to give you a scenario, could you tell me how that would be in a court case, and who’d win?

My mother and father are on bad terms. Both of them work full time, but my mother is the only one spending the money on food, clothes, the house, etc. while i have no idea where my father spends his money. Every week when my mother and father go foodshopping, my father always brings these tons of stuff that my mum has tried to express that we don’t need but he just manipulates her to buy them, especially for my mother to pay for the whole cart. Even though he’s with, my mum has to pay for the whole sum. Last week, she paid *$ worth of food only for one week, with *% of it being my father’s wants. My father never helps with anything at home. They both come home at 2PM each day, but while my father only sleeps and eats, my mum cleans the whole house, makes food, vacuums the house, folds clothes, etc. Every dinner we have together, you can see how exhausted my mum is, and us sisters try to help her, but after dinner, my father barely acknowledges her and just leaves to go to the mall and be with friends. After my eldest sister moved out to go to college, he took all of her stuff that MY SISTER told us i could get. He took my vacuum cleaner and said “it was broken” while it was in my hand sucking up stuff like a normal vacuum did, and shouted at me until i gave it to him. He forced my mother to use a car that was dangerous to use for over 8 years. It wasn’t until recent 4 months ago, where this stranger stopped us before we could get in the car and told us this car was dangerous to use and we needed to stop using it. After that my mother refused to use the car, and was looking for a new one with my eldest sister. Although my father did not want my mother to buy a car online, so he refused everything. Until he found this random ass cheap car and bought it. He spent 2 months fixing it, until he said it was good as new and told my mom to buy that car. Although he said she had to pay for the full sum of it, at 6000USD, which she did but with cash which was dumb of her. Now two months later, the car is nowhere to be seen, and everytime we try to ask him where the car is, he doesn’t tell us anything. Although i do remember him saying “Two years” which baffled me. But my mother doesn’t even care, she only thinks that he’s doing the best for us but he’s only manipulating us. Even worse, after my mum paid for the whole sum of the car, he put it under his name. And now we have nothing to do. Everything my mum has paid for (over *%) my father has put it on his name. The house, which my mum paid over *% off, is in his name. The cars, under his name. It is so annoying. Especially when i know he never spends any money on us. Idk how much money he has, or what he even does with it. It actually frustrates me.

Norway

But if we were to be put in court, what evidence would be acceptable?

What if we have no written evidence??

Us three siblings want mt mother to take action, but shes been manipulated so much that idk if shes too scared to do it or just shes starting to think that my fathers doing rhe right choice
