My neighbour left her house to her 3 children, she no longer lives in it but her grandaughter rents it. The grandaughter wants to buy the house from the three aunts (two are sisters and one is the wife of the now dead brother), she, the sister in law doesn't want to sell for such a low price (she wants her children to have more of an inheiritance. She also lives in Paris and this property is in Brittany)
Did I read somewhere that you now only need two thirds to agree to a sale?
We have a vested interest as we want to buy a small piece of their land and the ones that live here are agreed we can buy it.

Anyone with any knowledge on this subject?
