Before approaching the court you must understand some points for getting a good result.
Ancestral property is defined as the property whose title has not changed for last 4 generations i.e. from great grandfather to great grandson without being interrupted by any partition/settlement/sale/gift deed or will. If it is not so, then it is not an ancestral property. Property inherited upto 4 generations of male lineage (i.e., father, grand father, etc.) is called as ancestral property.Properties inherited from mother, grandmother, uncle and even brother is not ancestral property. Property inherited by will and gift are not ancestral properties. Self acquired property on the other hand can become ancestral property only if it is thrown into the pool of ancestral properties and enjoyed in common.
