What is likely to happen to my British passport if Scotland votes for independence? Will I lose it?

In the same way you can be a resident of the UK but a citizen of any other country, if/when Scotland brings out its own passport, I don't see there being any obligation to having to have a Scottish passport. There may even be a dual nationality option. More importantly in some ways if you are someone who has ties with both Scotland and other parts of the UK, you may have to pick your primary residence depending on which works out best for you in terms of taxation, state benefits etc...

If both countries allow duel citizenship nothing unless Westminster decides to revoke everyone north of the boarders passports. Considering what happened with Ireland I doubt they would be so cruel to the first generation of independent Scots. We might not get the share the pound but everyone who currently has a British passport right now will most likely keep it.

We carry EU passports issued by the UK Government. The UK currently allows dual citizenship. I see no reason the UK government would revoke anyone's passport post independence. In the event that the EU does reject Scotland's membership, that would require the Scottish government to issue non-EU passports. I'd want to keep my EU one in that event.

There's a lot of unknowns including timescales which is a significant factor, if there's a yes result that doesn't mean automatically when the result is announced Scotland becomes independent because there's so much to work out and agree. At a guess I suspect an arrangement would be made to allow existing passports already issued to remain valid, but they would need to be replaced and let's not forget all the embassies and consulates are British and UK passports belong to the British government not the individual.

The UK currently permits dual citizenship for citizens of other jurisdictions, and the Scottish Government has also stated that an independent Scotland will also do so. UK passports held by Scottish citizens will continue to be valid until their expiry date. Personally, I will be replacing my UK passport with a Scottish one as soon as I possibly can.

1) It will remain as a full UK passport until it expires. You should then be able to renew it if you wish. At present, it is ILLEGAL to render someone stateless. As a member of the EU, you also have the guarantee that you can retain your citizenship should you wish. 2) There was discussion about this, and it may be possible to qualify for dual nationality in the way that Northern Irish citizens have the option of an Irish or UK passport.

I lived in the Netherlands for some years, and never lost my UK passport then, nor was I forced to take Dutch nationality (even when I married a Dutchman). As an aside, I also didn't need to use my passport when travelling around Europe, or even re-entering the UK - so I always find the suggestion that passport controls going up at the Scotland / England border hilariously funny. It's all to do with the Schengen Free Travel Agreement - which both Scotland and rUK would remain signed up to, unless they opted out. In any case, there's no way that you could lose your UK passport if you didn't want to - although I would mention that e.g. journalists who travel abroad a lot tend to prefer to travel on an Irish passport if they can at all, due to it being a much safer option if there's a hostage-taking situation (UK citizens are seen as better bargaining chips, and therefore more at risk). An independent Scotland would, however, issue new Scottish passport for anyone living in Scotland who wants it. The same situation as Ireland, where anyone with an Irish grandparent can apply for an Irish passport, would almost certainly apply in the same way in Scotland.
