Preliminary and reservation agreements yes, the notarial deed at the notary
We say it plainly. Developer agreements and other contracts transferring ownership of real property require a notarial deed, and we do not compete with the notarial deed: it is done at a notary. We use SignSafe for preliminary and reservation agreements and accompanying documents, where a quick signature from a buyer who cannot always come to the office is what counts.
For a reservation agreement under the Developer Act, a handwritten signature is enough, and a SignSafe signature is a handwritten signature. Documentary form alone would not be enough. According to a legal opinion from Gałecki and Associates dated 21 August 2023, it meets written form (Art. 78 of the Civil Code). This summarises an opinion and is not legal advice; when in doubt, consult a lawyer. Where a qualified electronic signature is required, we can connect one in SignSafe.
We describe the documents below, and the general rules on the legal security page.
