son''s disability finances/PIP

Hi, I was wondering if anyone could advise me regarding my particular situation?
I have a court ordered shared residence order from 2011
My son, who is 17 and registered disabled, has lived with me for almost half the week (47%) since that time, and I am in receipt of carers allowance for him.
In all that time my ex wife, who has been in receipt of his disability benefits, has refused to share any, resulting in him being financially disadvantaged when residing with me. I would love him to be able to have access to his money 100% of the time, irrespective of who he is living with.
Is there anyone who might be able to give me some advice as I feel very helpless with nowhere to turn?
I am considering returning the matter to court under a specific issue order but not sure if it would be worth it?

I am sorry you haven't had a response. It does seem like an unfair situation. Your son's benefits are awarded on the basis of his needs and it is these that should be paramount here. On the other hand, because he has two homes, it is also arguable that the benefits aren't enough to support him and it is the primary home that should be prioritised.

I would think that a conversation with a benefits advisor at the CAB would be a good start point. It may be possible for the benefits to be divided and paid separately perhaps? Will they be paid directly to him when he is 18?
