Most of the couples with european woman buy the certificate without making any tests. Normal price 20 until 50 Dinar.
Not unusual in Tourist-region.

We've been married in a town without tourism. So the doctor wanted to earn more money and really made all the tests and radioligy ( heißt Röntgen auf Englisch so ?? ).
We had to pay 200 Dinar for me and my husband. HIV, Hepatitis and alcohol inclusive.
