hen considering a pension split, should it be from 18 when I joined or 21 when the pension started acruing?
Doubtless a legal type will prove me wrong, but I can't see how a pension that you didn't then have at age 18 on joining can be taken into account if it had no value until age 21?
Your own solicitor must have an idea, and if they don't, then consider getting one who does.
