Qualifications
The office of president is open to all Germans who are entitled to vote in Bundestag elections and have reached the age of 40, but no one may serve more than two consecutive five-year terms. The president receives an annual payment of approximately €213,000 that continues when he or she leaves office.
The president may not be a member of the government or of a legislature at either the federal or state level. On taking office the president must take the following oath, stipulated by Article 56 of the Basic Law, before the assembled members of the Bundestag and Bundesrat (however he or she is permitted to omit the religious references if so desired):
I swear that I will dedicate my efforts to the well-being of the German people, enhance their benefits, avert harm from them, uphold and defend the Constitution and the statutes of the Federation, fulfil my duties conscientiously, and do justice to all. (So help me God.)
