You can claim.on your father's ancestral as well as self acquired property as Supreme Court, Revanasiddappa v. Mallikarjun,[18] it was held that ‘Child born in illegitimate relationship/Void marriage is innocent and is entitled to all rights to property to which his parents are entitled whether ancestral or self-acquired property.
You have to submit proof in court of your father and mothers relationship and file an application further requesting DNA test to prove your claim that the person is your father. After the claim is established you can file a claim on property.
Prior to the child claiming a share of the inheritance, you will have to commence proceedings to have paternity established in court.
This is not entirely straightforward. Before the court orders a DNA test to ascertain whether the father really is the child’s biological father, the child will have to submit proof.
You will have to demonstrate that there was contact between the mother and father which could have resulted in the child being conceived. Witness statements from the mother, neighbours or friends are considered as means to demonstrate such contact.
The courts have nearly always granted claims by illegitimate children. The circumstances in which the child was conceived are no longer of relevance to the court. In the eyes of the law, all that matters is that the man fathered the child.
