evidence: You may have to present a public document (a document issued by a public authority) such as your birth certificate if you want to get married, or proof of the absence of a criminal record if you are looking for a job in another EU country. [...] These rules only apply to the authenticity of public documents, not the recognition of their legal effects outside the EU country where they were issued – this aspect is governed by the national law of the EU country where the document is presented. For example, if you have a same-sex marriage certificate issued in one EU country, the authorities of another EU country where you may present the certificate cannot require an apostille stamp for your certificate, but will not be obliged to recognise the marriage if same-sex marriage is not legally recognised in that country.
