What is a digital signature and why is it important?
A digital signature is a tool that allows the authentication of electronic documents in a secure and fast way. Unlike a conventional signature made on paper, a digital signature uses an encryption system to guarantee the authenticity of the signatory and the integrity of the document. In other words, it ensures that the document was signed by the indicated person and that its content was not altered after signing.
In Brazil, the validity of the digital signature is supported by Provisional Measure No. 2.200-2/2001, which established the Brazilian Public Key Infrastructure (ICP-Brazil). This legislation guarantees that digital signatures made with certificates issued by accredited Certification Authorities have the same validity as a handwritten signature.
This is particularly relevant for real estate purchase and sale contracts, as it eliminates the need for notarization, saving time and money.
The use of digital signatures is also a growing trend in real estate industry. In addition to simplifying the negotiation process, this technology reduces the risk of fraud and provides greater transparency to transactions. This means that both buyers and sellers can complete their transactions with greater peace of mind.
