I am so sorry for your loss.  It is difficult to understand what exactly is going on here with out reading the Will.  First, all that inherited have equal rights under the law.  But the executor can indeed force you out of the home depending on the estate's circumstances.  That would be after the Will is offered for probate and the executor is appointed.  He or she has no responsibility at all until appointed.  If he or she is not acting properly and "in breach of their fiduciary duty" then you can do something about it.  But what at this stage is unclear.  Please speak with some one in your area.  Good luck.
