Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Where does your daughter live?
Ok thats fine.
May I ask how much you currently earn (round figures) and what dependants you have?
May I just check - do you pay under a Court Order, via the CSA or voluntarily
Under Schedule 1 of the Children Act your daughter is entitled to apply to the courts for maintenance provided she can show that her income from all sources (including a part time job) does not meet her reasonable needs.
I suggest that you write back and say that if you receive full details of her income - from all sources - and her list of "reasonable" expenditure then you will consider the matter.
The percentage approach is not appropriate - and your commitments are also considered
Frankly I feel it is positively rude to ask you for more help when she does not have the courtesy to ask in person - but that is a personal not a legal opinion
Please ask if you need further details
My My what a large amount!
I would want a breakdown and to know what jobs she has looked for.
Offering to cover the cost of books etc is a good option.
