Looking again at the example :
Hope I'm not stating the obvious.
bear in mind me being rubbish at maths
Example - AFPS 05
A Servicewoman (salary of £20,000)
who has 15 years’ reckonable
service at the point of her divorce,
who is ordered to pay 50% (ie 71/2
years) of her pension accrued for
this period to her ex-husband, would
have her pension file annotated with
the amount of the sum to be debited
as a result of the Pension Sharing
Order. In this example the sum to be
debited is £2,143."
So at the date of divorce she has a pension worth 15 [years] x one seventieth of her annual salary at the date of divorce [£20k]so that's £4,285 a year and the non-member spouse gets 50% of that - an annual pension of £2,143 transferred to them?
With AFPS a pension credit member can't transfer out so it sits in the scheme index-linked to RPI - but the basis/AFPS pension promise will be a pension of £2143 a year with a bit added on for index-linking to the RPI to keep pace with inflation......
it looks as though the ex-spouse's pension credit income would be 50% of the total pension income at the point of divorce adjusted to account for RPI at the point of being paid to the pension credit member.
ie not much growth but at least keeping pace with inflation.
If you know the years of service and salary at the point of divorce and whether any years of service thresholds have been or are about to be passed - you can have a stab at working out a 50% share?
What the example doesn't show is what happens when the time comes to pay the pension credit member's pension - ie the adjustment for gender/age you're worried about.
in the example the AFPS member is female - so if her spouse is male - we don't know if they stick to paying the amount of annual income transferred - ie £2,143+ RPI additions or at the point of payment do they calculate a value/
CETV for the pension and increase the payments for his shorter life expectancy and in your case reduce them?
Can you work out what his pension income would be if he could take it at the date of divorce penny - is he about to pass a pension increase/years of service threshold?
