assinando

Assinando is the gerund form of the Portuguese verb assinar, meaning to sign. It designates the ongoing action of placing a signature on a document, whether by hand or by electronic means.

Etymology and form: Assinar derives from the Latin signare, related to signum or sign. The gerund assinando is used to express continuous action, as in ele está assinando o contrato (he is signing the contract). The related noun assinatura refers to the signature itself.

Usage and contexts: In everyday language, assinando refers to endorsing or confirming consent on various papers, such as agreements, invoices, or forms. A signature authenticates authorship or approval and can bind the signer to terms. The term is commonly seen in legal, administrative, and business contexts.

Electronic and digital signatures: Modern use distinguishes between assinatura eletrônica and assinatura digital. Assinatura eletrônica covers any electronic method of signifying assent, while assinatura digital uses cryptographic certificates to assure integrity, authenticity, and non-repudiation. In many jurisdictions, digital signatures are legally recognized when implemented with appropriate trusted authorities.

Legal frameworks: Brazil relies on the infrastructure of ICP-Brasil for certified digital signatures, established to regulate electronic documents and transactions. Internationally, regions such as the European Union recognize digital signatures under eIDAS, enabling cross-border validation of signed documents.

Impact and limitations: Signatures, including assinando, are central to validating contracts and records. The effectiveness depends on the applicable legal regime, the method used, and adherence to procedures that ensure authenticity and integrity.
