I work in benefits. It is legal for her to carry on claiming the child benefit even if the child does not live with her so long as she contributed at least that much to his upbringing. Tax creditds are different. They go to who the child is actually living with. It would be very unlikely to be seen as fraud by either of you, but would need to be paid back (by her) if it came to light.
My advice; stick with your solicitor. They may seem expensive but they tend to be good at what they do and the issues here are too important to be left to trust.
