Can the mother's housing and living expenses be deducted from the share of the brothers and sisters in the father's inheritance, due to their failure to pay their share of those expenses?

It is obligatory for children, male and female, to spend on their poor mother, by consensus. The distribution of the expenditure among them should be according to their financial capacity and ability, which is the most accurate view. If you agree to share the expenses equally, then your brothers must abide by the agreement. If they abandon it and you spend alone, you have the right to claim back what you spent from them, provided that you intended to claim it back and not to donate it to your mother. In this case, you may take your right from your brothers' share of the inheritance before handing it over to them, provided that no apparent harm results from it or you are not accused of theft.
