Marriage nightmare.

Advice nereded. I got married 18 months ago, I am on DLA. high-mobility,middle care, my wife claims carers allowance for me. and she works 12 hours a week at a care home. Who should be the main claimant for ESA? Since getting married i have lost all my disability premiums of ESA. I am in the suporrt group, and receive a DISABILITY INCOME GUARANTEE £22.60,,, My wifes earnings £86.00 are deducted from total esa £173.00. Meaning all we get from ESA IS £109.00 PER WEEK,, Also housing benefit and council tax has been reduced,And i have to pay bedroom tax on one room, which the wife uses regularly due to my disruptiveness in the bedroom. [sounds wrong..lol.].I have been claiming benefits since 1995 after a road accident,,, Would it be better if the wife became the main claimant, And if so, how do we go about that,, All help is appreciated,,Thankyou Peeps.x
