My mother passed away Nov. 2014. She made my elder sister executor of will. All four siblings, i.e. my two sisters, brother and myself are beneficiaries. My sister decided that she wanted to wait until October this year to sell - despite my advice that she may be missing an opportunity to take advantage of the currently excellent market. She is now suggesting that we make improvements to the house before selling, including painting hallway, etc. I do not wish to invest any money in this. My other siblings will no doubt side with the executor. Is she able to spend money on the property without my approval or does the majority rule?
