375.Part P makes rules complementary to the overriding legislation. The provisions in Part P are designed to facilitate the transfer of the notional capital value specified in the order into separate scheme rights for the scheme member’s ex-spouse or civil partner (rules 91 and 93). There are also some modifications following the consequent reduction (under section 31 of the 1999 Act) of the pension rights of the MSP or office-holder scheme member (rule 92).
