Hello Tim, welcome to the forum.
For the annulment which is a Philipppines process, a UK lawyer is of no use. It has to be done in the Philippines and will require her to go there. It's a long process... be both patient (search in the forum, you will find useful infos). In not done yet, you will need to hire a good attorney in the Philippines for this (and carefully follow his/her work, it's not easy from the UK).
Then for your girlfriend, it depends what is her status in the UK (regarding immigration and visa).
