Scottish citizens will be able to apply for a Scottish passport from day one of independence, with a Scottish passport costing the same as a UK passport. People will be able to continue using their existing UK passport until it expires. They can then choose to get a Scottish passport when their existing passport is due for renewal.
Scotland’s Future explains that we’ll remain part of the Common Travel Area between the nations of the British Isles. Being part of the Common Travel Area means people won’t need a passport to travel to the rest of the UK or Ireland.
You dont need a passport to travel to and from ireland so why would scotland be different.
