How is the estate of a person who died in 2003 divided, knowing that it includes a shop, and that the value of the shop and the debts have changed since the date of death?

Full siblings are excluded by the lineal heir (descendant). The mother gets one-sixth, and the remainder goes to the sons and daughters, with the male receiving the share of two females. The inheritance is divided into 54 shares: the mother gets 9 shares, each daughter gets 5 shares, and each son gets 10 shares. The debt is to be paid as it was incurred before the distribution of the inheritance, and 400,0 pounds should be paid if that is the original debt. As for the real estate inheritance, its value is determined by the market price on the day of distribution.
