How is the estate of our father, who passed away in 2006, to be distributed? Is it according to its value at the time of death or its current value after it has increased?

As long as the inheritance has not yet been distributed, every heir now owns according to their share, and the daughters own from the lands and houses according to their share. If any part of the property is sold, each daughter takes her share from the current price, not its value at the time of the father's death. If one of the heirs requests to sell a property that cannot be practically divided, it must be sold and its price distributed, and the one who refuses the sale is compelled to do so.
