That is the sensible and grown up thing to do
Don't be wary of the Authority, go and ask.
I have heard, albeit I hold my hands up readily and potentially unreliable third-hand information to admit on a public forum, that a certain Greek FTO claims the Hellenic Civil Aviation Authority recognise the UK ATPL theory. Thus the claim is a UK JAR theory pass and undertaking a Greek JAR CPL is perfectly acceptable.
So do though be wary of claims made by training organisations. Their interpretation of the law is not binding.
Stroll on EASA I say hopefully with less binding national rules.
