Question: In June 2005, Alex Conveyed a four-acer lot, Redacre to Eunice in these terms: "to my wife Eunice and her heirs" at the time of the execution of the conveyance, Alex and his wife Eunice had three children Lucy, mary and Nancy. Alex died in 2006. Eunice started dating MArk after the death of her husband Alex. Eunice died in September 2008, leaving a will by which she devised Redacre to Mark. It is common ground that the three children are the heirs of Eunice. the children are contesting the validity of the will on the grounds that their mother had only a one acre share of the property and that each of them is entitled to one acre and no more
