Pension advice in divorce

Hi thanks for your help.
I am starting divorce proceedings with my soon to be ex wife.
Prior to getting married we said we wouldnt go after each others pensions if things turned bad. I have messages to confirm this. We sadly havent worked out, so now she is coming after my pension. Do the messages have any legal standing or am I fighting a losing battle? I have put alot of money into my pension prior to the divorce to keep a roof over our heads - catch 22 - earned more to pay the bills so contributed more. I am in a real quandry here.

thank you for helping me

All contributions to a marriage are equal so you won’t be considered to have contributed more because you earned more.

The messages about not including pensions won’t carry any weight.

Ah right. I thought the gentlemans agreement might hold weight (she works in local government - who would have thought that you cant trust the local government).
Thank you

Have you got pension valuations?
If she is in LGPS it’ll probably be worth a lot more than either of you expect.
