The result of a paternity test for courts and registry offices is an expert forensic report that can be used for legal purposes. It need not involve unpleasant court disputes — the most common uses are entering the biological father in a child's birth certificate, removing a non-biological father from it, or single mothers needing to name the father of their children in order to claim their rights. As mixed marriages become more common, expert reports are increasingly required by registry offices too. Such a report must be submitted when applying for Czech citizenship for a child born to a Czech father and a mother who is a citizen of a country outside the European Union.
A DNA test with an expert report requires the collection and analysis of the mother's DNA as well. In exceptional cases, however — for example when the mother is abroad and unable to attend in person — and where the father is named in the child's birth certificate, the report can be prepared without her. The identity of everyone whose sample is taken (father, mother and child) must be verified: validity of identity documents, a thumbprint from adults and photographs. The sample must therefore be taken in the presence of the court-appointed expert or an authorised person, at our premises in Prague 6. In special cases samples for an expert report can be taken elsewhere, in the Czech Republic or anywhere in the world. The standard turnaround for an expert report is 14 days, and shorter deadlines are possible.
