Family membership

A family member must be certified by the Sony Health Insurance Society to be named a dependent. A family member will not be automatically certified as a dependent simply because he or she is a dependent for tax purposes or is your spouse.
The most important conditions for dependent certification are that the dependent must have certain familial ties to the insured person and that his or her livelihood must depend primarily* on the income of the insured person. Other requirements apply as well.

  • * Depending primarily on the income of the insured person:

    As a general rule, the insured person must provide for at least one-half of the dependent’s cost of living. However, if the actual income status of the family member for which certification is requested and that of the insured person differ significantly from ordinary cases or if certification may be considered inappropriate in light of societal norms, the family member may not be certified as a dependent.
