When members get divorced or their civil partnership is dissolved, the Court takes the value of their pension into account in any settlement. If a member’s pension includes an underpin amount, then that increase is included and, if their pension is shared, part of that increase will be passed to their former spouse or civil partner.
For most members the pension they built up in the career average scheme is higher than they would have built up in the final salary scheme, so no underpin applies and there is no change to the pension share awarded to their former spouse or civil partner.
