Dear client,
I'm sorry to hear about the complicated situation with your father's properties. It can be challenging to navigate these legal matters, but I will do my best to provide you with some guidance.
Firstly, regarding the gift deed and will, it's important to understand that gift deeds and wills are two separate legal instruments. A gift deed transfers the ownership of the property immediately, whereas a will only transfers the ownership upon the death of the testator (your father in this case). So, the 4 acres of land gifted to your father's second wife belongs to her, and it is not part of your father's estate that is subject to distribution under his will.
Regarding the litigation on the 3 acres of land bequeathed to you in your father's will, it would be best to consult a lawyer who can help you navigate the legal system and provide you with the best course of action. Filing a partition suit may be an option, but it depends on the specifics of your case and the laws in your jurisdiction. It's also worth noting that if the litigation results in the land being transferred to someone else, then that land will no longer be part of your father's estate and will not be distributed according to his will.
Regarding the ancestral property and the third party's claim, it's crucial to gather all relevant documents and evidence that establish your father's ownership of the property. This evidence could include sale deeds, property tax receipts, and other relevant documents. The court will decide the ownership of the property based on the evidence presented, so it's essential to gather as much evidence as possible to support your claim.
In conclusion, I recommend consulting a lawyer who can help you navigate the legal system and provide you with the best course of action. It's important to gather as much evidence as possible to support your claim to the property and to be prepared for the possibility that the litigation may not be resolved in your favor.
