From partially relevant experience
You'll have to court it. She has probably convinced herself she's right. A solicitor will (mostly) only tell her she is right, or at least that the court can be convinced she's right. It's only when you stand before an actual judge you'll get the truth out. Unless you've got convictions or she's got actual evidence of irresponsible behaviour then she'll seriously struggle.

In these sort of things solicitors rely on fear and a gamble that you won't take it all the way. I was particularly impressed that a solicitor won't respond seriously to a letter you write unless you pay a solicitor to write exactly the same words for you. Which is a bit fucked up, no?
