Your uncle has no claim on the bungalow whether for himself or his children. It is mom-in-law's prerogative to give to who she wants.

As for the RM500K property mom-in-law helped pay RM100K for it but will make no claim on the property. Appreciate her generosity.

I don't see what is your uncle's problem. In terms of inheritance, sons are favoured over daughters. Sometimes daughters get nothing or just a token sum.

The wife should not speak out and sour the relationship with her mother and brother. It is unlikely to change anything. Just accept that the bungalow is going to her brother. Inheritance does not have to be distributed equally.

Your uncle should not stir shit that he had to pay most of the household expenses because his wife paid for her house. This is the norm in many households. The husband pays everything while his wife keeps her salary for herself. Unless husband's salary is insufficient then wife will contribute.

There is no need to castigate a man who expects his wife to contribute to household expenses. These days women want equality. A wife may earn as much as her husband. Buying a home may require the joint income of both husband and wife. The concept of a husband paying everything and wife keeps what she earns is outdated. Please update yourself.

It is even more amazing that a lot of people still think that the husband should pay for everything and it is an outrage to expect his wife to contribute to family expenses. A lot of old mindset here.
