Calculating statutory inheritance shares under Japanese Civil Code requires determining statutory heirs and their fractional shares based on survivor ranks. This Skill automates computing inheritance distributions across spouse, children, parents, and siblings by processing structured relationship inputs and outputting percentage shares.

Simultaneous death in Japanese inheritance law prevents heirs who die at the same time from inheriting from each other. This Skill applies simultaneous death rules to determine statutory heirs and compute valid inheritance shares for the remaining survivors.

Substitution in Japanese inheritance law allows descendants of a predeceased heir to inherit that heir's share. This Skill calculates substitution scenarios for children and siblings, automatically distributing fractional and percentage shares to the substituted heirs based on structured input.

You can compute estate distribution for a deceased person with a spouse and children by providing structured JSON input describing the survivors. The calculator validates the input fields and outputs the statutory heirs with their corresponding fractional and percentage shares under Japanese law.

Calculating statutory heirs requires structured JSON input containing fields such as deceased_name, has_simultaneous_death, spouse, children, parents, and siblings. The Skill processes these structured relationship inputs to output heirs with fractional and percentage shares plus contextual legal notes.

Automated Japanese inheritance share calculations are limited to statutory heir determination under the Civil Code and do not account for wills, estate tax, or property valuation. The Skill outputs fractional shares with contextual notes and legal disclaimers, but does not provide binding legal advice.
