My father in law owned a free hold DDA flat in Delhi and a residential plot in Kanpur, UP. I got married 5 years back and since then we are staying in the same DDA flat with the family. My brother in law and his wife were living separately on upper floor of same flat. My father in law had differences with my brother in law and his wife. My father in law expired 2 years back and and brother in law expired after 9 months, mother in law was staying with us. She also expired 9 months back. Now from her belongings we have got a registered will of my father in law in which he has bequeathed the flat and land to my husband and his only sister with a major part to my husband and disowned my brother in law and his wife. We consulted a lawyer and were planning to get a probate but now brother in laws widow has filed a suit to put a stay on the transfer or selling of the property to any third party and to get 1/3rd share from the property.
Please guide us, what to do? Apart from replying to her, do/can we still go for probate of the will. We have a registered will, now she still has any right to the property, they were married for last 9 years and have no issues. This is my father in law's self earned property, not an ancestral one.
