@SW-User oh no worrieeeesss.
I don't know much about laws myself.
It depends entirely on the will of the one passing. If they died unexpectedly and did not leave a will, then 1/3rd goes to the man's siblings, the rest is divided among the offspring and wife. Because of the division, all assets including the house is mostly converted into money in order to exactly match the distribution.
Sometimes a person will leave a family member with power of attorney. But here in South Asia as most marriages are arranged, in laws including spouses are not trusted with this position. So even after decades of being married, spouses rarely have power of attorney. This is also the reason spouses will each try to buy property with their money so that in case of a bitter divorce they have a shelter. And they never ever gift their property to their spouse. Joint account are also extremely unpopular here. It's also the reason abusive men will seize their wive's salaries, because financial freedom would help the women get out of abusive relationships. Seizing salaries and not allowing women to work are like clipping a bird's wings here, commonly used tactics of oppression.
