Ratuldas, I do not think that we have any "great souls" around these days, let alone in this forum. However, let me answer your question as an ordinary mortal: There is absolutely no way that your wife can put in a claim on a property bought by your father when you were twelve years old. That said, properties do get entangled in matrimonial litigation indirectly. If, for example, your property is revenue-generating and you default in your maintenance payment, then she can seek an attachment on the rent or some form of lien against the property to repay maintenance owed to her. Any liens or injunctions from selling the property can be burdensome but do not entail giving of ownership rights to her. Many advocates fail to explain to their clients on the difference between ownership rights, right to residence and getting properties attached for failure to pay maintenance. Wives are not entitled to ownership rights, period. Many husbands are ill-advised to transfer their properties to their brother, sister, etc. to escape the clutches of wives' demand. That is the worst advice that an advocate can give to his client.
Of course, if the wife has contributed to the purchase of the property and can prove it or if the property is jointly owned by the couple, then we are dealing with a whole different scenario but that is not the case with your property.
So, relax... enjoy your property... pay your wife a fair share for her maintenance... but no more. Simple? Of course a great soul may advice you differently, like giving away everything you own to your wife. So I suggest that you stay away from "great souls."
