We have my parents and DH's dad still alive so no inheritance received as yet. When ex-DH's mother died, we had been married 8 years, two DC, his mum was a widow and he an only child. We had separate finances, which was very much to his advantage as he earned at least 3x what I did. He paid off the mortgage and this reduced his monthly outgoings and made f-all difference to mine. I suspect I received some of the benefit in my divorce settlement though!
As for the current situation, I am not sure what will happen. DH is one of 3 DC and his parents' money will be split three ways with the house going to the youngest DC, as agreed with the older two who are both high earners by some margin. The house is worth about 130k.
I am one of two children, and there is a significant disparity in finances between me and my DSis. Despite this, our parents always treat us exactly the same, the only exception being that they paid for her breast reduction surgery after it had been cancelled twice by the NHS, which I wholeheartedly supported as she had triple negative breast cancer and needed a reduction before they could start radiotherapy. I would have paid for it myself, if needed.
When both of my parents pass, I think I might like to buy a property that my DC could live in. This would be awkward if DH disagrees. We really haven't discussed what will happen (we have no shared children) and for me, as we haven't children together, and we are financially secure with no debts, inheritances should be used in a way to benefit the next generation.
