Is it ok:
I undersigned Mr. ABC Notary in Bangkok, registered College Notary of Bangkok, certify that this copy composed by No. 1 sheet, in accordance with original performed by Ms. XYZ.
Interesting translation but how would you translate then : Iscritto al Collegio Notarile dei Distretti Riuniti di A, B e C? (Where A, B and C are three different towns)Good job Tim -- I would only note that 'collegio notarile' is the local chapter of the notaries' guild. I would therefore render it as notarial district rather than college.
