Aww Glenice ,
Sorry to hear that it is turning into a trawl for you.
Firstly occupational Pensions and Private Pensions can affect the amount of both Incapacity Benefit and ESA (Contribution based). They ignore the first £85 pw of them and reduce your amount by half the difference. eg if you receive £90 total in pensions then they will reduce payment by £2.50.
With regard the IBM 164 , i cannot find reference to it anywhere.. what questions did it ask, and i am presuming the IBM stands for Incapacity Benefit Migration.( was it to do with your pensions?)
Just supply all information requested , including additional medical evidence .
Pensions can change over time , so perhaps that is why they are asking .If they were under £85 they may have been disregarded totally and no amount put "on the system".
Unfortunately not a lot you can do in the meantime except wait on a decision, and get help if anything does not go smoothly.Keep copies of everything .
Hang in there .
