degree of kinship
Legal term used in family law to measure the closeness of a blood relationship, such as between parent and child (first degree) or siblings (second degree).
The Civil Code stipulates how to calculate the degree of kinship.
The closer the degree of kinship, the stronger the inheritance rights.
Compound of 親 (しん, 'parent; relative') and 等 (とう, 'grade; class'), literally meaning 'kinship grade'. The term is a modern legal coinage based on classical Chinese elements.
