Real Property

my mother died and left some heir property, but now will. Some real property she had purchased would be given to four siblings, there are 12 siblings and 7 of us signed a paper allowing the youngest to get property at said location. Then he got with another brother and added a piece of heir property handed down from our grandmother to this same paper, which the rest of us knew nothing about. Had the properties put in his name. He did not get the other signatures but had an add put in the paper and when no one came forward he had the properties put in his name. The rest of us knew nothing about this and did not know he was getting all the property put in his name. we found all of this out after the fact, when he confessed to several siblings what he had done. Can the contest this matter? And was fraud committed when he added the other property to this paper?
