Does my sister have the right to have a say regarding our mom`s money?

Anonymous

I have an older sister who is married and she earns her own money as she works and her husband is a family judge and he earns pretty well. Our dad passed away 10 years ago and he leftmy mom with a monthly pension. Now my mom is 85 years old. Since she is an elderly person I lets say take care of her and so does my brother. Im single and so does my brother. My mom still is independent in some things but at the same time she now needs help in certain things she did not need help in the past, like managing her money as if it was for her she will waste it in unnecessary things and not to pay important things at home like utilities, debts, etc. She is a bit of compulsive when she has money on her hands, but she always was like taht when my dad was alive. So is the reason why me or my brother need to manage that pension in some way. My brother and I are both single and we dont have kids, the reason we live with our mom and take also care of the house, the house we grew up with and the house my sister when she was single she also grew up with. My brother does nto have an stable job sometiems he has a job sometimes he does not, cause the money he earns for a living depends on the work he is given, he does not receive like a month set salary. He is a dental technician. Me on the other hand I was fired from my last job like 2 years ago and due to my age, where i live it had been very difficult to find a job as most companies where I live they prefer to hire younger people and not people my age so the opportunities for me is less than for younger people. Me and my brother and mom are simple people, we dont waste money in fancy stuff or trips or anything like that so often, cause we are not rich.. Just sometimes we indulge in certain things but it is food mostly not trips, or new technology or anything like that not even on clothes.

My sister believes my brother is abusing of our mom money cause sometimes my brother

ask mom to borrow him money and my mom always say yes because it is her son and she does with the money whatever she wants.

ask her to collaborate in something for mom but she complains my brother is abusing of our mom money. We dont see it fromt hat perspective. We are the ones in the house with mom taking care of her and my mom decides what she does with her money. My sister and her husband lives well, they are not rich but they live well and they dont even have kids, but they like to travel often and treat themselves often.
