No stamp on my wife passport
Hello everyone. I'm Italian and my wife is Brazilian. She came from Brazil and entered Italy on 18 may 2026 and the Italian authorities did not stamp her passport because we entered together in the EU citizen line. We plan to go to ozora by car from Italy. Brazilian citizens do not need a visa for the Schengen space but can't stay for more than 90 days. What if we get stop by police, how can she prove she is in the Schengen space no more than 90 days if she have no stamp on her passport? We will pass through Slovenia while driving. We have our Italian matrimony certificate, but I don't know if this document is enough in addition to her passport. Thanks all.
