From June 1942, Widows' Pension Class B was paid to widows without dependent children who were aged 50 and over. The term "widow" included de facto widows who had lived with the deceased spouse for at least three years prior to his death and had been maintained by him. Eligibility was also extended to deserted de jure wives who had been deserted for at least six months, divorced women who had not remarried and women whose husbands were in hospitals for those considered to be insane. From July that year, Widows' Pension Class B (WPb) was exempted from income tax.
