Helen,
There was a time when I used to know quite a bit about this subject, but I have not done CAB for about five years now.
Firstly, would you share with me whose name the tenancy is in ? Your sole name ? or something different ?
The second question is, is the maintenance paid under a Court order or
Separation Agreement or is purely voluntary ?
You see, it would strike me that, if someone is paying £500 p.m. to you and an equivalent sum to your daughter, then both of you are getting £500 a month and this does not change when she reaches a certain age - unless of course the agreement or order provides otherwise. Unless I have misinterpreted you, you are still getting the £500 p.m. and the daughter is getting the same. The fact that she may no longer be a child does not alter this. Your income remains £500 a month. It would be wrong to re-allocate the income.
There are, however, two possibilities, which are as follows :
1. If you are responsible for a dependent child, you will normally get a plusage on your housing benefit to take account of your extra responsibility, known as a child premium. If your current rate of benefit is calculated on the assumption that you have a responsibility for a child , and that responsibility has now ended, your child premium will drop off and your benefit will reduce.
2. There is another possible factor called a non-dependent deduction. What this means is that, if you have someone in your household who is not dependent on you ( eg an adult child ) then there is a policy assumption that the non=dependent will make a contribution towards his/her accommodation, the actual deduction being calculated by reference to the non-dependent''s income. Not all non-dependents will give rise to the deduction, but where it is actually occurs, the law assumes that the non-dependent will make good the deduction out of his or her own pocket.
I don''t know if your daughter lives with you, perhaps you had better tell me.
Unfortunately right now I am in the United States, and will not be back for two weeks and am separated from my textbooks. So I''m not 100% sure that this is right, but I would advise an early consultation with a CAB or other benefits agency.
