Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How much is the house worth and how much is outstanding on the mortgage?
Who owns the property - and are you married?
What income do you have
How much do you claim as a dividend - and how much are you paying towards the house OTHER than the mortgage?
Sorry - that is your only income?
How much does "everything" amount to?
Since the house is in your sole name the CMS (new CSA) will not count the mortgage as maintenance.
If you change all the other bills into her name and send her the same amount to cover them then that money WILL count as maintenance and you will have nothing to fear from the CMS
I hope that this is of assistance - please ask if you need further details
