Frequently asked questions
What is Certification of Existence and how does it differ from a Notary Public?
Certification of Existence is when a Notarial Services Attorney confirms that a specific document, right, or act truly existed at a given time, serving as evidence. This differs from certified true copies (Notary Public), which primarily confirm a document is a genuine copy of an original.
How can this service be applied to Intellectual Property?
We can certify the existence date of inventions, source code, patents, models, or creative works. This establishes a priority date for intellectual property rights, preventing plagiarism and copyright infringement.
Are there any limitations to certifying the existence of documents?
A Notarial Services Attorney can only certify what can be genuinely verified or presented to them and must not be contrary to law or good morals. We cannot certify mere speculation or future events that have not yet occurred.
