FAQ
What is a notarial act for digital evidence and what is its legal utility?
A notarial act for digital evidence is a public instrument through which a notary public certifies the existence, accuracy, and context of facts verified in electronic media. It secures pre-constituted evidence backed by notarial public faith for use in judicial or administrative proceedings (Lei nº 8.935/1994, art. 1º).
How should WhatsApp conversation screenshots be presented to draw up a notarial act?
You should not bring only printed or isolated screenshots. The ideal approach is to present the original smartphone directly at the notary office or via videoconference so that the notary can verify the telephone number, message history, audio files, and account integrity (Lei nº 8.935/1994, art. 6º).
Does a notarial act of a website lose validity if the page is later taken offline?
No. A notarial act for digital evidence perpetuates the facts witnessed by the notary at the time of access. Even if the website page or social media post is subsequently removed, the notary certificate retains full evidentiary value (Lei nº 10.406/2002, art. 215).
