Thank you for your question
My name is Clare
I shall do my best to help you but I need some further informtaion first
Just to check - there is no surviving spouse?
Did the one sibling live with her?
Are you aware that the site charges more for a phone call?
Did the sibling who lived with your mother make a financial contribution to the house?
How much is the Estate worth in total?
What contribution was made?
In the absence of a Will your mother's Estate should be shared equally between the six children - including the house.
It is possible that the sibling who lived there could argue that he (or she) is entitled to make a claim against the estate on the basis that they were reliant on your mother to provide them with a home - and it is possible that they would get a larger share of the Estate because of that.
However they would NOT get the house and accordingly if five of you wish to honour your mother's wishes then the sibling who is going to receive the house may hav eto offer sibling 6 a cash settlement
I am sorry not to give better news - please ask if you need further details
That is harder to assess without more knowledge of the Estate
Add up the assets - take away the costs of the funeral etc and divide by 6
That is the most the sibling could get - so knock some off and make an offer
You are most welcome - I hope all goes well
