The Brexit-Übergangsgesetz is draft German legislation that would provide legal clarity during the transition period foreseen by the draft Withdrawal Agreement where provisions in German federal law refer to membership of the European Union or the European Atomic Energy Community. This includes aspects of naturalisation of British citizens in Germany and German citizens in the UK.
The proposed law would enable British citizens to retain their British citizenship when taking German citizenship and to become dual national citizens, even when a positive decision on the application for German citizenship is made after the expiry of the transition period, provided all other requirements for German citizenship are completed before the 31 December 2020.
With long residence requirements and long processing times in some areas of Germany, this proposed law potentially avoids certain Britons falling foul of the deadline and losing their right to dual citizenship , simply because their applications could not be processed before the end of the transition period.
