A property was purchased in 2000. All the persons whose name were in the record of 7-12 document have sign the sales deed and agreement. The agreement was also registered. Now I have constructed an house, two daughters who identifies as the legal heir of the original seller are asking for their rights in the property. However their names are no where in the 7-12 document and hence they were missed in the sales deed and agreement. Now can they claim the property. Out of 15 legal heir involved in sales deed and agreement 12 have expired. Will I loose my property. Is their any rule which can help me.
