Ancestral property is defined as one that is inherited up to FOUR generations of Male lineage and should have remained Undivided throughout this period.
For your understanding and clarification the property should have passed on from the Great Grandfather to the Grandfather and from Grandfather to the Father and then to the person concerned.
If you are an NRI who has an Ancestral Property, you can rest assured that you have a share in the same. Ancestral property is always a property acquired from these immediate Paternal Ancestors.
Earlier only sons or male members were entitled to get a share in the Ancestral property but now even daughters or female members are entitled to get a share in their ancestral property. The sons and daughters have a right in the ancestral property by birth.
Ancestral property cannot be the subject matter of a WILL and cannot be sold or disposed of unless such a sale is for the benefit of the family.
If you have been denied of your rightful share in Ancestral property then you can send a notice to the erring party and can even file a suit for partition of Ancestral property. Further, you can seek an injunction from the court as well.
