MIL passed away 18 months ago. A few months later DH received a letter from FIL lawyer asking if he wanted to make a claim on MIL estate. DH said no and I will be honest that he assumed that he would be gifted some money because PIL are quite wealthy from inheritance and various other streams. I was pregnant with DC1 at the time and we have been saving to try and move to a house out of an apartment but live in a big city so obviously it's taking time.
Anyways the estate settled and FIL has never mentioned another thing about it. He has made the odd "when I die you will get money" strange joke but otherwise no mention.
What would have happened if DH had told the lawyer that he did contest? Not that it makes any difference now but I will admit he is quite bitter about it all considering FIL knows we have been trying really hard to upgrade to a house.
FIL lives in Scotland if that makes any difference.
