Mycat Co., Ltd. (Head Office: Meguro-ku, Tokyo) has significantly renewed the "Valuation Tool" for its special contribution information service "Special Contribution Navi" (https://tokubetu.xyz), which converts caregiving contributions into monetary amounts. Tool URL: https://tokubetu.xyz/tools/care-valuation### What is the Special Contribution System?The revised inheritance law, enforced on July 1, 2019, newly established the "Special Contribution" system (Article 1050 of the Civil Code). This system allows relatives who provided gratuitous care or other labor to the deceased (the decedent) to claim monetary payments from the heirs. Before the revision, relatives who were not heirs (e.g., cases where the eldest son's wife had long cared for her father-in-law) could not assert any rights in the inheritance division. The special contribution system was created to rectify this unfairness. However, awareness of the system remains low. According to inheritance-related legal consultation data released by the Japan Federation of Bar Associations, consultations regarding special contributions constitute only a small portion of all inheritance consultations (Source: Japan Federation of Bar Associations). It is believed that many people miss the opportunity to claim due to lack of awareness.### What has Changed with the Renewal?The previous tool simply displayed an estimated amount range upon inputting the type and duration of care. With this renewal, it is now possible to input caregiving details more finely, and the estimated amount is presented with clear grounds for calculation. **Input Items (After Renewal)**- Relationship to the care recipient (e.g., spouse's parent, spouse's sibling's spouse)- Type of care (physical care, accompanying to hospital, household help, supervision, coordination with facilities)- Frequency and duration per session of care- Period of care provided- Degree of care needed (if certified)- Whether other relatives shared the care burden **Output Content (After Renewal)**- Daily care contribution amount (calculated based on care fee standards)- Cumulative contribution amount over the entire care period- Tendency of awarded amounts in court precedents (explaining points of contention regarding the proportion of contribution)- Estimated range of contribution amounts based on the scale of inherited assets- Checklist of evidence materials required for claims.### Basic Principles for CalculationCurrently, there is no clear legal formula for calculating the amount of special contributions, and much is left to the court's judgment. However, in practice, the following factors tend to be considered. **Comparison with Care Fees**The fee unit price for home-visit nursing care under the Long-Term Care Insurance (around 4,000 yen per hour for physical care) may be referenced as a standard for monetary evaluation of contributions (Source: Ministry of Health, Labour and Welfare, "Structure of Care Fee Calculation"). This tool calculates the daily contribution amount based on this fee unit price, considering the nature and duration of care. **Proportion of Contribution in Court Precedents**In judgments from the Tokyo Family Court, there is a tendency to recognize around 50-70% of the equivalent care fee amount as a special contribution for caregiving (nursing care) (Source: Ministry of Health, Labour and Welfare, "Structure of Care Fee Calculation"). This tool presents a range reflecting this tendency. **Relationship with Inherited Assets**Special contributions cannot exceed the value of the inherited assets acquired by the heirs (Article 1050, Paragraph 4 of the Civil Code). This tool allows input of an estimated amount of inherited assets and displays the upper limit range. ### Recommended Usage Methods**Case 1: For those who have long cared for their in-laws**Individuals who have cared for their spouse's parents at home can use this tool to check "if they can claim anything" when inheritance occurs. Those who keep a care diary can input the records into the tool to grasp an estimated contribution amount. **Case 2: Families with imbalanced caregiving burden among siblings**Dissatisfaction like "I'm the only one caring for my parent" is a major cause of inheritance disputes. While the special contribution system targets relatives other than heirs, the contributions of heirs themselves can be claimed separately as "contribution share" (Article 904-2 of the Civil Code). This tool also explains the difference between special contributions and contribution shares. **Case 3: For those who want to grasp the monetary sense before consulting a lawyer**Individuals considering consulting a lawyer but "have no idea how much they can claim" can use this tool for preparation before consultation. Showing the tool's output to a lawyer allows for a more concrete consultation. ### Future Feature AdditionsSpecial Contribution Navi plans to add features such as outputting a template for special contribution claim forms and providing a list of documents required for mediation applications to the Family Court. We aim to enhance information provision so that relatives who have provided care receive fair evaluation.※ The calculation results of this tool are estimates and do not guarantee legal claim amounts.
