Should my sister stay out of it and calm down or she has the right to butt in?

I have a married sister but since she does not live in my house (the one she used to live when she was single many years ago) she believes she had lost control over to decide on things she believes she still needs to ahve control of. Ok she is married but she has her own house and now I believe she does not have any right to control or decide on things in the house I live with. I dont get involve or has a say in her house. My sister is the older sister she is 55 years old. The thing and this is irrelevant. I live with my brother and my mom who is elder or a senior. My brother and I are the ones taking care of our mom in the house (my dad passed away 9 years ago, he was a medical doctor) and maybe I give my sister the benefit of the doubt that beause she no longer lives in our house, she can't decide on things that matter to our mom or that decide on things she can't see due to she lives somewhere else as she is married so for that impotence perhaps she needs to be like an inspector in our house. any chance she gets when she stops by the house or see us or visit us. She has to know the way my brother and I take care of mom, if she is filling her needs, is like she does not trust my brother or me on that.

My brother and I in any moment is neglecting our mom we are always with her and try she is ok. My sister is aware of that sure and she had thanked us before but somtiems my sister gets overboard and believe my brother and I has to do more. She does not help us financially or help my mom financially (at least cooperate with something, not that she has to collaborate with a lot of course) for her medical issues, the house things, all of that my mom pays it with her own money my dad left her maybe because of that my sister feels she does not need to cooperate in anything. My sister what she likes is criticize and question my brother and I that we dont do things fast at the house, we take our time but is not that we dont do it simply we are more laid back on that,

less stress and sure we take our time to do it when we are able to do it not when my sister believe has to be done. My sister is stressful, because that is the way her husband is and she picked up on that when she married my brother in law, she became more strict in certain things and she likes to apply that on us.

For instance since we dont have like lot of money for some house repairs (my house is old for sure), ceiling, get rid of old stuff, buy new things) we had to save money for many

repairs our house needs, so each time my brother and I believe there is extra money for a certain repair we do it, and that could take time, but according to my sister, our house is old t and we have to fix many things fast or buy new stuff for the house. But like I said she complains and nags but financially she does not help in something if she wants things done faster at her pace not our pace. My brother from time to time support the house too.
