In Personal documents, Humand uses an electronic signature: a set of electronic data attached to the document that identifies who signed it and confirms that the document was not modified after signing. In addition, each signed document shows the collaborator's name and the date and time of the signature right next to it.

• The collaborator opens the document from My documents, clicks Sign document, draws their signature in the box, and confirms with Sign. They can do this from the app or from the web.

  

  To see the step-by-step process from the collaborator's side, check How do I sign a personal document?

• Below the signature stroke, inside the same box, the document shows:

  Detail	What it indicates
  Signer	First and last name of the collaborator who signed.
  Date and time	Exact moment of the signature, with its time zone. For example: 10/13/2026 10:47 GMT-03:00.

  

  This detail is printed on the PDF, so it is visible both in Humand and when you download the document and share it outside the platform. It applies to any type of document (payslips, contracts, policies, etc.) and does not require any configuration.

  The text below the signature is shown in your community's language, regardless of the language each collaborator uses on the platform.

  Documents signed before this detail was added keep their signature as it was. The signing date is still recorded in the electronic signature data of the PDF.

• Keep the following in mind about Humand's electronic signature:

  • It is the same mechanism used by well-known document signing platforms.

  • It is legally valid in several countries, such as Mexico, Argentina, the United States, Uruguay, Ecuador, Colombia, and Spain.

  • Unlike a digital signature, it does not require the collaborator to complete any procedure with an authorized entity.

• The signed PDF includes the signature data and integrity validations. You can view them by opening the file with a PDF reader that displays signatures, such as Adobe Acrobat Reader.

  If the document is edited outside Humand after it was signed, the signature is no longer intact. You can confirm this with an official signature validator, such as validadordefirmas.gob.ar.
