Are you paying money via the Child Maintenance Service or Child Support Agency or as a result of a court order? Are you now continuing to pay the amount you were paying before? On what basis do she want more money?
If any of the money you were paying was in respect of spousal maintenance, you should stop it now because that finishes on marriage.
Child maintenance continues whilst the resident parent is in receipt of Child Benefit and the child is under 16 or under 20 and in full-time non-advanced education. Here are the government notes.
here is the government leaflet on the amount that you should be paying telling you how it’s worked out.
child maintenance via the Child Maintenance Service or Child Support Agency is based upon your income, not her need.
Can I clarify anything for you? Please rate the service positive so that I get paid. We can still exchange emails. Best wishes. FES.
