I currently live overseas and have done so since 2010. I previously held a UK driving license, but have somehow managed to mislay it. Can you advise how I can get a replacement. Thank you.
UK drivers licenses can be replaced, even from overseas, but only if the applicant resides in Great Britain. See this UK govt. page, which addresses license replacement, and contains the following text:
...To replace your licence you’ll need to: be a resident of Great Britain (there’s a different service in Northern Ireland), not be disqualified from driving for any reason pay £20 by MasterCard, Visa, Electron or Delta debit or credit card provide addresses where you’ve lived for the last 3 years.
Thus, to replace your previous license, you'll have to lie to DVLA about your residence. None of us would recommend that course of action.
