Listing agreement and signature

Is the electronic signature on the listing agreement legally valid?

The signature is given through a connected signature service, and Doxario archives the associated evidence so that it remains provable later who signed and when.

Whether the signature level used is sufficient for your particular contract is a legal question, not a product one. It depends on the contract type; if in doubt, have it checked by a lawyer.

What the product side can contribute is two things:

  • Evidence. The records belonging to the signature are archived and not altered afterwards.
  • Version history. Where an agreement is revised, the new version supersedes the old one without overwriting it — the previous version is retained as superseded.

None of this applies to the notarial deed of purchase itself: that is executed before a notary, not in Doxario.
