Pension in payment

I wonder if someone can advise me on a pension matter.

i am a pensioner and my divorce is now completed and payments made etc over a month ago.

My ex has the right to claim 25% of my private company pension pot. So far this has not come out (as seen from my pension pay slip). My solicitor indicated to me some time ago that the longer she takes to claim that 25% the better it is from my point of view. Is this right and can she back date the claim to the date of the settlement. In other words claim 25.10% or whatever the figure is? She is not of pensionable age and has to transfer the monies out of my company scheme.

The scheme has 4 months to implement the pension sharing Order after it has received from your ex all the information it needs to implement the order, including where her share is to be transferred to and a copy of the Decree Absolute.
The CETV is recalculated by your pension scheme on a valuation date chosen by your pension scheme during that 4 month implementation period.
25% of that new re-calculated CETV will be transferred to your ex.
In my case the Pension Sharing Order arrived at the pension scheme about 6 weeks after Decree Absolute.The court can't issue the Pension Sharing Order until Decree Absolute has been issued and a completed Pension Sharing Annex has been sent to court by your ex.
