DWP sending out letters on my husbands and my private pension

i am not a mod on here but here how it works for me. if your pension is over £85 a week tey will halve the amount above the 85 quid and deduct it from your esa payment, doesnt matter if you are in contribution group, i am myself, once my pension went above £85 a week they halved the amount above 85 quid, i am having about a tenner removed each week' and i am in support group, i dont know why they want your husbands pension details unless he is on benefits.
