Medical pension....can wife take half at divorce?

Hello,
I have been seperated from my wife for nearly 3.5 years. We have two children over 18 who are not in full time education. The eldest does not live at home. the youngest is unemployed and gets jobseekers allowance. My wife works part time and lives with my youngest in the privately rented house we shared for over 20 years.
I have a Prison Service medical pension, which is my main income, and just about pays my rent and council tax a month. I work as a jobbing actor from time to time, but do not make enough to live on from this alone.
Is my wife entitled to any of my medical pension when we divorce?

Hi Jez,
Sorry to confirm,what you maybe already know,but yes pensions are shared,my sol is going after half of my stbx,and his is going after half of mine.
That''s fine cos his is worth far more than mine.

Take care
Luv and cwtchs
