viscera.
I know there area number of support services for transgender people in Glasgow, both official and voluntary.
While I'm not, by any means, a lawyer, I do understand the principal of Scottish law. Deception, generally, needs to involve some gain.
Example. I changed my name while I lived in Scotland, according to statutory procedure. All I needed to do was write to almost everyone who needed to know, asking them to use my new name. Apart from some family members, everyone did. My passport, driving licience, education and professional certificates, welfare and so on, all agreed to use my new name. Then I issues a statutory declaration with a Notary. I couldn't change my birth certificate because it is N American. But I wrote to them and recieved a letter back in my new name, acknowleging receipt. My name was then, legally changed and that is recognised throughout the world, just as with more complicated procedures.
My point is that, this is not the sort of legal system that would, potentially, prosecute some young guy because he woos a girl by telling her he's an astronaught!
There must have been some material gain from the deception. However, time will tell.
