All I can say is that I seem to remember that the CTC are not adverse to people joining up and then immediately hitting them for legal advice etc. (not like, for example, the AA who specifically state that you can't do a call out until at least 24 hours after joining).
However I could be mistaken about that - they have a forum on their website that might be worth trawling through.
You could always ring them up and ask them, I'm sure it's a question they get asked a lot, so they'll probably understand. I think it's membership(at)ctc(dot)org(dot)uk or 08447368451 - no harm in asking

Anyway, hope it all works out in the end
