My daughter left her job 2 weeks ago, she has been looking for another one since then, shes 19 and lives at home. Would the money she recieves, if shes entitled, depend on my earnings and my husbands.
your money has no bearing on your daughter's entitlement to benefit. she can claim Jobseeker's Allowance. if she has paid enough NI contributions she can get JSA(C) (contributory), otherwise it's JSA(IB) (income based) where they look at other income/savings etc, but only for herself and a live-in partner, if appropriate.
she may well get a "sanction" if she left the job of her own accord.. a suspension of benefit for a period of time.
