What is an Apostille?

An “apostille” is a form of authentication issued to documents for use in countries that participate in the Hague Convention of 1961. Please see the list of participating countries here.

Can I apostille copies of my documents?

In certain cases yes. The issuing Secretary’s office will require you to have your copies officiated by a Notary Public prior to submitting for authentication. Most states allow notaries to certify copies. States that currently do not permit this practice include Alabama, Alaska, Kentucky, Illinois, Indiana, Kentucky, Michigan, Mississippi, Nebraska, New Jersey, New York, North Carolina, Ohio, South Carolina, South Dakota, Tennessee, and the District of Columbia. Other States restrict the type of documents. Such as California which limits Notaries to certifying copies of powers of attorney or if requested by a court or Secretary of State. Florida and Pennsylvania for example, authorize Notaries to certify copies of most documents. However both States do not allow certifying copies of marriage, death, and birth certificates. Each state has varying sets of rules which is why it is important to inquire with your Notary if document copy certification is allowed by their commission.

Professional and efficient – Having not been through the Apostille Service previously, we were guided and taught what we were doing by extremely professional and courteous individuals. We couldn’t be more pleased at the efficiency and the speed at which they were able to get the job done. The final product was accepted by the bank and the beneficiaries of the estate received their funds, everyone was happy. Thank you, One Source Process, Inc.

One Source Process took good care of me! Their personal care and attention to detail is hard to find! I was dealing with a deadline for a visa and in dire need for help understanding the process. They made everything so easy and I met my visa deadline no problem. I am so appreciative and I recommend them to you!
