Inheritance

Gifting land to one's son during one's lifetime

Q: My grandfather has several children. He had bought some pieces of land on his 3 eldest sons' names. While he was alive he sold two of the plots of land of those two sons' marriage expenditures, but kept the third plot as it is. 

Also, my grandfather did not buy land for his remaining children, but he however left behind a house without a will. 

Now, my grandfather is no more. The 3rd plot of land was bought on my father's name and is still on his name. But my father's siblings are now asking for a share in his plot of land. 

My question is whether they are entitled to any share in my father's land?

Paying zakaat once one acquires one's share of the inheritance

Q: Regarding inheritance/working out zakaat, an estate has only money, no business, etc. 

The house and car of the deceased was already given to his wife in his lifetime - it was accepted and agreed by all during his lifetime that it belongs to his wife. 

The person passed away 3 years ago - the estate got sorted out last week and shares were given. 

Must the zakaat be give for all the previous years while they were sorting out the inheritance? 

And when do they pay zakaat for the share that was received? Should it be paid now or would they wait for a year to pay it?

Woman making wasiyyat to gift her house to her husband's heirs

Q: I would like to find out if this method is correct. If not, what would be the best method?

Fidyah for a person who suffered from dementia

Q: A man passed away, leaving behind his wife, a son, two daughters, a brother and a sister. 

Let's say he left an estate valued at $100,000. He had verbally expressed his wish to give one-third of the estate to charity, but there is no written will. 

How should his estate be calculated and distributed according to Islamic inheritance laws? 

Additionally, because the deceased was ill for the last six months and suffered from dementia, he was unable to perform Salah (prayers) during that time. Should Fidyah be paid for the missed prayers, and if so, from which portion of the estate?
