Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Which part of the UK does the father live in?
Then she can issue a Court applictaion for child maintenance here in the Uk - and will then be able to enforce it if need be.
Clearly it will not be easy dealing with this from Peru - but she can instruct a solicitor to deal with it
Please ask if you need further please
You can do this - and she can "appear" via video link
You are most welcome i hope all goes well
