In another question asked by you, you have mentioned that your father expired recently. I presume that “recently” means not later than 12 years. In such a situation, since your sister is living in the property of your father, then previously she would have been living there either in her capacity as daughter or as per the “family deed” mentioned by you. In my opinion, this previous period when your father was alive, cannot be included in the adverse possession since at that your father might also be staying there who was the owner of the property. And, since your father died recently, she would not be in adverse possession for a period of 12 years after his death. So, I do not think the adverse possession principle would apply in this case.
Moreover, she is not in exclusive possession of the property, since you said that you are also living in the same property (20% of the area). One of the requirements of adverse possession is exclusive possession. So, this ingredient is also not satisfied.
Further, as per your own version, she is apparently claiming title under the “family deed”. So, the ingredient of “hostile possession” which is required for adverse possession, is also apparently not satisfied.
Likewise, it appears that you have already started litigation in respect of the said property before the expiry of the 12 years period. Or, you may be about to start such litigation within such period.
In view of these reasons, I feel that it may not perhaps be possible for your sister to claim adverse possession. I have written all this on the basis of limited knowledge of detailed facts of your case. For a proper legal advice, you should show all relevant documents and details to some lawyer.
Similarly, without having seen all the relevant documents, it is not possible for me to tell you whether you should file for partitioning of the property as per Hindu Succession Act or should go in for declaration of the family deed as null and void. In fact, at another place, you have also mentioned that you have a will in your favour, but you don’t want to get it probated. So, these appear to be complicated questions of facts on which I cannot offer a correct solution without having seen the full contents of the relevant documents. It is in your own interests that you must show all relevant documents to some lawyer and obtain his considered opinion.
