Tool URL: https://tokubetu.xyz/tools/care-valuation
### What is the Special Contribution Fee System?
Under the revised inheritance law enacted on July 1, 2019, a new "Special Contribution Fee" system was established (Civil Code Article 1050). This system allows relatives who provided free medical care or other labor to the decedent to claim monetary compensation from the heirs. Before the revision, there was a problem where non-heir relatives (for example, an eldest son's wife who cared for her father-in-law for many years) could not assert any rights in the division of the estate. The special contribution fee system was created to correct this unfairness. However, awareness of the system remains low. According to inheritance-related legal consultation data published by the Japan Federation of Bar Associations, consultations regarding the special contribution fee account for only a tiny fraction of total inheritance consultations (Source: Japan Federation of Bar Associations). It is believed that many people are missing the opportunity to claim simply because they are unaware of the system.
### What Changed in the Renewal
The previous tool only displayed an approximate price range when the type and duration of care were inputted. With this renewal, users can input care details more finely, and the tool presents an estimated amount after clarifying the basis for calculation.
**Input Items (Post-Renewal)**
- Relationship to the cared person (spouse's parent, sibling's spouse, etc.)
- Type of care (physical care, escorting to hospital, domestic help, monitoring, coordination with facilities)
- Frequency of care and time per session
- Duration of care provided
- Care requirement level (if certified)
- Whether care was shared with other relatives
**Output Contents (Post-Renewal)**
- Daily caregiving contribution amount (calculated with reference to nursing care remuneration standards)
- Cumulative contribution amount over the entire caregiving period
- Trends in approved amounts in court cases (explains how the contribution ratio becomes a point of contention)
- Estimated range of contribution fee based on the size of the inherited estate
- Checklist of evidence required for making a claim
### Basic Concept of Calculation
Currently, there is no explicit legal formula for calculating the special contribution fee, and much is left to the discretion of the court. However, in practice, the following factors tend to be considered.
**Comparison with Nursing Care Remuneration**
The remuneration unit price for home-visit nursing care under nursing care insurance (around 4,000 yen per hour for physical care) is sometimes referenced as a standard for monetary evaluation of contribution (Source: Ministry of Health, Labour and Welfare "Calculation Structure of Nursing Care Remuneration"). This tool calculates the daily contribution amount based on this nursing care remuneration unit price, combined with the content and time of care.
**Contribution Ratio in Court Cases**
In adjudication examples by the Tokyo Family Court, there is a tendency to approve around 50-70% of the equivalent nursing care remuneration as the contribution fee for medical care and nursing contributions. This tool presents a flexible price range reflecting this trend.
**Relationship with Inherited Estate**
The special contribution fee is restricted so that it cannot exceed the value of the estate acquired by the heirs (Civil Code Article 1050, Paragraph 4). This tool allows users to input an estimated amount of the inherited estate and also displays a guide for the maximum upper limit.
### Recommended Ways to Use
**Case 1: Those who have cared for parents-in-law for many years**
Those who have cared for their spouse's parents at home can use it to check "whether they can claim anything" when inheritance occurs. Those keeping a caregiving diary can grasp the estimated contribution amount by entering that record into the tool.
**Case 2: Families with uneven caregiving burdens among siblings**
Dissatisfaction like "I am the only one caring for our parents" is a major cause of inheritance trouble. While the special contribution fee is a system for relatives other than heirs, the contribution of the heirs themselves can be asserted separately as a "contribution portion" (Civil Code Article 904-2). This tool also guides the difference between the special contribution fee and the contribution portion.
**Case 3: Those who want to get a sense of the amount before consulting a lawyer**
Those considering consulting a lawyer but "having no idea how much they can claim in the first place" can use it as advance preparation. By showing the tool's output to a lawyer, more specific consultation becomes possible.
