A Patta or a Chitta Adangal is not a title document.
A registered sale deed alone is the title document to the property.
If the property bought by Samantham was transferred to his daughter Dhanlakshmi, you may verify that how it was transferred on her name and whether the previous owner transferred it by executing a registered settlement deed or by bequeathing the same through a Will or whether the co-sharers executed a registered release deed relinquishing their rights in the intestate property of Samantham n her favor, if so how many co-sharers executed the same and how many legal heirs survived the deceased, whether the legal process of transferring the property Samantham in hr favor was followed or not. This verification is essential so that you can avoid any possible litigation by a any legal heir of the deceased Samantham at a later stage seeking partition and his share in the property because there is no limitation for filing a partition suit.
You can ask Kabilan to produce the details as mentioned above and can show them to a local advocate to seek a proper legal opinion on the proposed purchase of this property to confirm the safety of your invested amount.
If there is no death certificate and legal heir certificate, Whether it is acceptable if , the Patta , Chitta and Adangal is in Daughters name .
A patta cannot be changed on her name without a death certificate of the property owner and same is the case with the Chitta adangal too.
