I filed a succession case in which I made the children of my deceased defendant a party. The children of my deceased defendant have never filed any document to prove that they are the legal heirs of my deceased defendant. In my SUCCESSION petition I mentioned that the 3 respondents are the legal heirs of my deceased defendant. I have only asked for my half share in succession in my prayer. I also said in my plaint that the current defendants should file a separate suit or counter claim. I wish that my prayer be allowed and that the 3 respondents or the children of my deceased defendant should file a declaration case to prove themselves as legal heirs of their deceased mother.

In the scenario you have described, it seems like you have filed a succession case claiming your share in the inheritance left by the deceased defendant. You have named the deceased defendant's children as respondents in the case, alleging that they are the legal heirs of the deceased.

Under Indian law, for the children of the deceased defendant to establish their status as legal heirs and claim their share of the inheritance, they would typically need to provide relevant documents (such as a death certificate of the deceased, birth certificates of the children to establish their relationship with the deceased, and any will or testamentary documents if applicable).

If the children of the deceased defendant have not filed any documents to prove their status as legal heirs in response to the case, the court may require them to do so in order to determine their rights in the succession. Your plea for your half share in the inheritance could be granted by the court based on the evidence presented.

Your mention in the plaint that the current defendants should file a separate suit or counterclaim suggests that you are open to further legal proceedings if the respondents wish to challenge their status as legal heirs or claim a share in the inheritance. It would be up to the respondents to decide whether to file a separate suit or counterclaim as per the legal advice they receive.

Ultimately, the court will decide the outcome of the case based on the evidence and arguments presented by both parties involved. It is advisable to consult with a lawyer specializing in succession and inheritance laws to guide you through the legal process and ensure your rights are protected.
