In the case of there being no current Chief I'd see if I was able to locate a Clan Society and seek to identify with them.
As far as this being 'usual' practise in Scotland, whilst I dare not profess to represent the views of all Scots, in my experience most kilt wearing Scots I met through the now defunct Scottish Tartans Society were much less legalistic in their approach than pragmatic. They tended to wear the tartans with which they self identified; or quite simply liked the look of.
In over 50 years of kilt wearing I've been asked many questions about my kilt, clan crest badge or tartan. Never yet has any self appointed member of the 'Tartan Police' mentioned that my surname is not Sinclair.

Bring Forrit the Tartan.
Thank you JohnnyO for the info and clarification.
