In Ireland, if a farm is left behind, then the farm is valued by the state, and the siblings are told to decide who wants it. The one receiving the farm in the end, pays the value to the remaining siblings (minus his portion). The siblings are free to waive any payments and simply sign off, but they must come to a mutual agreement. All this before any deeds are changed.
My husband’s father had the chance to get a beautiful 3 story house on one of the largest lakes in Ireland. One of the siblings had just married, so the other 9, who all had small farms or lived abroad in the UK simply signed it over to uncle Martin.
They never dreamed it would have the value it does today, and they were happy to give Martin the chance.
Every time I see it, I sigh. It’s lovely. But, they did the right thing.
In the case of persons with no heirs, they go by the will which may name another non-related party, or it goes to the state. Two elderly gentlemen in the village left their huge farm to a cousin of my husband whose only connection was that she visited the men in their old age often. The struggling niece was not given anything, and she had been their housekeeper and cook for years and never asked for a dime in return.

But she was out of luck. Seems we you can never tell what a person is going to do in advance. The young girl had no idea she was inheriting anything. She herself is very wealthy, and was kind of embarrassed. Not enough to sign it over to the niece though.

Caused quite the stir in the village. I can imagine it does break up families when poorly managed.
