Documents are not interchangeable. Before requesting a certificate, identify the event you need to prove and the format required by the authority or organization that will receive it.
A full certificate reproduces the contents of an entry in the Civil Registry. The request must specify the event and provide the details needed to locate the entry. The purpose of the request may affect the type of certificate, who is entitled to request it, and the information that may be disclosed.
This is a church document confirming what is recorded in the relevant register. It may be useful in historical or family research. Whether it will be accepted for a particular procedure must be checked with the receiving organization; it does not automatically replace a civil registry certificate.
Within the scope stated in the certificate issued, it confirms that the event is not registered in that registry. It must not be presented as proof that a person never existed or that an entry cannot be found elsewhere. It is also different from finding no result in an online search.
Ask the receiving organization which document and format it accepts.
Identify the registry, archive, or parish that may hold it.
Check the required details, eligibility, and authorizations.
Clarify whether an apostille, legalization, or translation is needed.
Keep the organization’s response, including a negative one.
If the person, date, and registry have been identified, a specific request may be possible. When those details are missing, it is advisable to obtain a quote for a search first. The organization’s processing times and the possibility that the record cannot be located should be explained in the terms of the engagement.
