How can I say I can't guarantee information I'm about to give is correct?

Answer 1

You will hear or read the phrase "Ohne Gewähr", e.g. when the winning lottery numbers are published...

Answer 2

Ich kann leider nicht garantieren, dass die Informationen, die ich Ihnen momentan zur Verfuegung stellen kann 100% korrekt sind.

This is the sentence in German. However, in German culture, you would also expect the person to tell you why you cannot guarantee that the information is correct. What's the reason? And by when can you confirm it's correct or provide correct information? Germans have a very high level of uncertainty avoidance and an extreme need for details and precision. They can accept that you may not have 100% correct information right now, but you need to communicate why, by when you'll have it, etc. I hope this helps ....
