Parents died left a will diving house and cars between the 3 sisters. One sister is living in the house with here grown children for free what can I d

If the house has already been probated and the property is now jointly in the names of you and your sisters you can file a partition action to force the sale of the home. I have handled many of these partition suits in the past and they virtually always result in either the sale of the property or one party buying the other party or parties out.  If the estate has not been probated than we will likely need to open probate first to get the assets transferred to you and your sisters, followed by a partition action.
