Does anyone know the most convenient way to get a signature notarized for vehicle bought in United States Thanks

Visit a public notary or possibly see if the US embassy in Bern can do it for you.

My husband recently went to our local Gemeindehaus to get some documents notarised with no problems at all.

You do realize that to notarize a signature, the document must be signed in the presence of the notary, i.e. you cannot notarize an existing signature.

The US Consulate in Zürich can notarize documents as well. That way
you don't have to travel to Bern.

I believ every Swiss qualified lawyer can do this, but kit sure if the US authorities would accept it from someone who is not actually a notary

All Swiss lawyers are also notaries.

Yes but I don't believe they all have the notarial stamp.

I've yet to see one who doesn't.

In Italy this is the case, but we are NOT in Italy.
