TMPP Total Mortgage Protection Policy Poser!!

Hi learned friends,

I am sure this has been mentioned many times but as i am new to site not sure what the guidance is so would appreciate some if possible please.

For what ever reason i have only just realized there was an insurance payment coming out of my account for TMPP and has been for "5" Years after jogging my memory I can vaguely remember being pressurized by Halifax into taking it or it effecting our ongoing mortgage when an endowment was cashed. They virtually said it was a must to cover the mortgage. To add to this it was for JOINT mortgage holders of which my partner and myself have not been together for 4 years and I have not been living in the house

So the first question is...

Is this or was this miss selling and can it be claimed back and if so where from ?

The second issue is that I have not had a mortgage for 18 months as it was finally paid for and the mortgage given to my ex partner and her other half.

So my second question.... What about this 18months of payment when i was not even in the house or had a mortgage and had no requirement for the insurance, surely the halifax who insisted on it originally should have informed me or at least stopped it ?

Any advise gratefully recieved

Alan
