5(1)For the purposes of paragraphs 1 to 3 above in their application to a Category B retirement pension to which a married woman is entitled by virtue of her husband's contributions, a married woman who retires (or is deemed by virtue of section 27(5) of the principal Act to retire) before her husband shall be treated as deferring her retirement until he retires and her period of deferment shall accordingly be treated as ending with the day before that of his retirement.
(2)References in sub-paragraph (1) above to the retirement of a woman's husband shall, where the marriage is terminated before he retires, be construed as references to the termination of the marriage.
(3)In the case of—
(a)a Category B retirement pension to which a married woman is entitled by virtue of her husband's contributions ; or
(b)a married woman's Category A retirement pension with an increase under section 10(2) of this Act attributable to her husband's contributions,
the reference in paragraph 2(3) above to the pension to which a person would have been entitled if he had retired on attaining pensionable age shall be construed as a reference to the pension to which she would have been entitled if she and her husband had so retired.
(4)Paragraph 4(2)(c) above shall not apply to a Category B retirement pension to which the wife was or would have been entitled by virtue of the man's contributions ; and where the Category A retirement pension to which the wife was or would have been entitled includes an increase under section 10(2) of this Act attributable to his contributions, the increase to which he is entitled under that paragraph shall be calculated as if there had been no increase under that section.
