Hi Steve and a warm welcome aboard Filipino UK

Interesting introduction to say the least.......it's the end of a busy day so I'll need to read it again to properly unravel

I'm guessing you've got a good handle on the needed evidential documentation for the visa application.
Apart from the mandatory English Test and TB certificate it's largely a matter of meeting the Financial Requirement and meeting the relationship stuff. The rest is all pretty straighforward.
Shouldn't really need a lawyer unless there are major complications relating to immigrations rules.

You'll find plenty of useful info here......just search.

You'll also find a friendly, knowledgeable and good humoured bunch of folks
