Provisions excepting prescribed relatives from insurability have applied since the Social Welfare Act 1952 came into operation in January 1953. Under the provisions of the Acts and Regulations, employment in the service of the spouse is expected from insurance. Also excepted is employment of defined categories of relatives in the common home or a corresponding home. However, a prescribed relative who is employed under a written contract of service or apprenticeship is insurable.
These provisions continued the conditions that had applied under the former National Health Insurance Acts where such employment without money payment was excepted from insurance.
