Q: In 1999, my mother-in-law executed a Will in which she had given her land to my wife and her younger sister with a condition that they will get the the ownership and rights after her death only. My mother-in-law expired and now my wife want to sell the property and buy another property in Hyderabad. Can she selling the property on the basis on the existing will or she need to get a fresh document registered which shows her as the sole owner of the property?
yes, you can surely sell the property without any freshly registered documents. but you also said that your wife's sister is also in name for the property. if it so then you need to make a document stating that she doesn't have problem selling the property.
As you said that your mother-in-law had already bequeathed her land to your wife. There is no need of fresh registered document based on the Will only she can transfer the property to her name and also sell it.
