30 foreigner-conducted marriages annulled in France

Posted Jun 30, 2014 by Anne Sewell
At least 30 marriages in France, celebrated between 2012 and 2013, are now null and void. It turns out the Portuguese-born councilor who conducted the services does not have the power to do so. They'll now have to get married all over again.

In seems that in France, foreigners without French citizenship can be elected as local councilors. However, they cannot become mayors or deputy mayors and this means that they are not legally allowed to conduct marriages or other civil ceremonies.
Unfortunately no one told Mario de Oliveira, who conducted the 30 marriages in the Paris suburb of Aulnay-sous-Bois.
Le Parisien newspaper confirms that UMP mayor of Aulnay, Bruno Beschizza, stated that the couple's marriages are illegal and that they must be declared null and void. All the couples affected will now have to get married all over again.
Nouvel Obs suggested that the situation could raise a few legal issues for the couples, especially around the question of inheritance.
Apparently back in 2011, the Minister of Interior in France confirmed that for foreign nationals elected in France to have the right to conduct marriages, it would be necessary to change the French constitution.
