As a Notary, I can undertake any of the functions usually classed as notarial work, and most typically I am asked to authenticate, attest and certify - for both individuals and companies - documents that are to be used abroad. Many documents that are to be used abroad require certification and different countries have differing procedures and requirements for this. You are likely to need the services of a Notary if you are buying or selling property abroad, getting married abroad or doing business abroad (especially if you are authorising someone else to act for you in the foreign country e.g. by granting Power of Attorney to them).
