"2. From 1948 to 1975 married women were permitted, by theNational Insurance (Married Women) Regulations 1948 , to elect to pay a much reduced national insurance contribution – reduced, that is, by comparison with the full rate of contribution they would otherwise have paid. The amount was a flat rate of a few pence per week. A married woman who chose to pay the reduced rate of contribution received also limited benefits, I believe only industrial injuries benefit. Particularly, there was no entitlement to state retirement pension; a married woman who elected to pay the reduced rate became dependent on her husband's contributions for her pension. The eligibility requirements and the consequences of making an election were spelt out in Leaflet NI1, published by the then Ministry of Pensions and National Insurance. At the end of the leaflet was a form of election, identified as CF9, which a married woman was required to complete and return to her local social security office, in order to indicate whether she wished to pay contributions at the full or the reduced rate. Although the form indicated that it was to be returned whatever the election made, I did not hear evidence about the Ministry's practice in those cases in which it was not. 3. In 1975 the system changed in some respects, in particular by the replacement of the former flat-rate contributions by a contribution linked to earnings. A married woman who elected to do so was required to pay at a rate of 2% of earnings while those paying the full rate contributed an amount which varied from one year to another but was typically about 6.5%. A married woman who had elected, before the changes in 1975, to pay reduced rate contributions was treated as having elected to continue doing so, and did not need to make another election. Indeed, it seems women in that position were not invited to reconsider elections they had already made. In 1977 the right to make an election to pay reduced contributions was abolished, but those who had already made one were allowed to continue paying at the reduced rate."
