We've purchased 1 acre of ancestral property (land) from two brothers, these two brothers shared/partitioned it from his father after his death, their father did not leave any WILL before his death. In year 2001, these two brothers sold this one acre to us without their daughters permission(who were majors when the sale transaction happened in year 2001) . Now, this year in Feb of 2010, the daughters of these two brothers filed a case against us in court caliming they have rights on the property. What could happen to our purchased property now? Is there any time limit on when someone can claim their rights after a sale is happened? What all options do we have here in this case?
