Reservations, handover protocols and annexes signed remotely, the notarial deed at the notary

SignSafe collects buyers’ signatures on preliminary agreements, reservation agreements and protocols: a phone, internet and a finger are enough, and signing takes a minute, even from abroad. We do not compete with the notarial deed; the developer agreement is still concluded at a notary.

SignSafe is a tool for electronic document workflow and for collecting signatures from buyers, including those without a qualified signature: the buyer receives a PDF and signs it with a finger on a phone, without an account, in a minute. Developers use it for preliminary and reservation agreements, protocols and consents. We do not compete with the notarial deed.

SignSafe speeds up signing the documents that surround selling flats and houses online: preliminary and reservation agreements, protocols, annexes and consents. You automate document workflow, cut paper formalities and shorten the time it takes to settle matters with a buyer. Customer data is stored on servers in the European Union, and less paper means lower handling costs and a more efficient sales team. We do not compete with the notarial deed.

What you gain

Faster signing of the documents around the agreement, less paper and a more efficient property development business.

Easier management

Simpler document management in complex building projects: signed documents sit in one account and the status of every signature is visible live.

Lower risk

A faster document flow reduces the risk of delays with reservations, handovers and annexes.

Transparency

More transparency and control over signing contracts with subcontractors: you see who has signed and who has not yet.

What usually gets in the way

An interested buyer cannot come to sign the reservation

A reservation needs a quick reaction. Waiting for a visit or a courier leaves the unit held without formal confirmation, or the buyer backs out.

Many buyers, many protocols and annexes

With handovers and technical changes the office juggles emails, printouts and folders to know who has signed which documents.

The buyer lives abroad

Paper circulation of accompanying documents stretches by the postage time, and the developer cannot see where a document stands.

What you get

From a phone

the buyer signs the reservation, protocol and annex, also from abroad

One place

signed accompanying documents are on the account, not in folders

Clear limit

the notarial deed stays with the notary

How it works

You save document templates

You save the reservation agreement, handover protocol and technical annex as a template with fields for buyer and unit details.

You send the document to the buyer

You pick the buyer from your contact list and send a link. You can also send to several people at once, for example spouses.

The buyer fills in and signs

They open the link in the phone browser, complete the fields and sign with a finger. No account.

The office receives the PDF

An email notification announces the signature, and the document is on the account at once. You see the status in real time.

What you can do

  • Preliminary and reservation agreements for units
  • Unit handover protocols and key handover confirmations
  • Technical annexes, for example on fittings or dates, where they do not require a notarial deed
  • Buyer consents and declarations, including GDPR
  • Formal correspondence with buyers that needs confirmation
  • Documents for buyers abroad signed remotely
  • Reservation agreements signed on a device in the sales office or from an e-mail
  • Contracts with subcontractors in complex building projects

Who it is for

  • Residential and commercial developers and their sales offices
  • Customer service teams handling reservations, handovers and correspondence with buyers
  • Sales offices working with buyers from other cities or from abroad
  • Projects where many formal documents remain in circulation after the agreement is signed at the notary
  • Project delivery teams that conclude contracts with subcontractors

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.

Where e-signature helps a developer: the documents around the agreement

Examples of use in the sales and buyer-service process:

  • Preliminary and reservation agreements. The buyer reserves a unit with a handwritten signature on a phone before you arrange the visit to the notary. The template is set by the developer’s lawyer.
  • Handover protocols. Condition of the unit, defects and meter readings in one PDF. The buyer and the developer’s representative sign it on the spot on a phone or tablet.
  • Technical annexes. Changes to fittings or dates of an administrative nature, if they do not touch elements requiring a notarial deed.
  • Consents. Consent to contact, to data processing or to receiving correspondence electronically.
  • Formal correspondence. Confirmations of receipt of letters, schedules and information from the developer.

We describe similar uses for agents in e-signature in real estate.

A sales office day with e-signature

A buyer living abroad chooses a unit during an online call. Instead of waiting for a visit, they get a link to the reservation agreement and sign it on a phone in a minute. The sales office sees in the panel that the document is signed and blocks the unit in its own system.

You then set a date at the notary, where the developer agreement is concluded as a notarial deed. SignSafe takes no part in that, because we do not compete with the notarial deed.

At handover, the buyer walks through the unit with the developer’s representative, and the protocol with comments is completed and signed on a tablet. The finished PDF goes to the account, and the buyer gets their copy.

After handover an annex appears on a small change to the deadline for fixing defects. The buyer signs it on a phone, and the office has the full set in one place. Developers with their own sales system can automate sending through the API.

Four ways to sign at a developer

A buyer may sign a preliminary or reservation agreement in the sales office or remotely. SignSafe offers four ways to sign: e-mail with a one-time code, no password; e-mail with an account password; signing on a device at a point with no login; and signing on a courier's or supplier's tablet. You can also prepare a document as a template with fields for the other party to fill in. These are examples of use.

Subcontractors and the contract flow in a complex project

A large development generates many documents: besides buyers’ paperwork there are contracts with subcontractors and specialist trades. You send them in SignSafe to one or several people at once and see in your account who has signed and who has not. This shortens the time work waits for formalities and reduces the risk of delays.

Subcontractor contracts are a separate thread from buyers’ documents, so you can run them on separate templates and in separate contact groups. We describe similar uses for design and engineering firms. The scope of use depends on the type of document; if in doubt, consult a lawyer.

Security and legal basis

Documents and signers’ data are stored on servers in the European Union (OVH hosting).

For business customers we sign a data processing agreement.

A SignSafe signature is a handwritten signature and, according to a legal opinion from Gałecki and Associates dated 21 August 2023, meets the written form requirement (Art. 78 of the Civil Code); at the least, the declaration is valid in documentary form (Art. 77² of the Civil Code). Where a qualified electronic signature is required (the electronic form under Art. 78¹ of the Civil Code), we can connect one in SignSafe. We do not compete with the notarial deed.

Gałecki and Associates, legal adviser Tomasz Gałecki · 21 August 2023

Legal nature of a signature placed by hand on the touch screen of an electronic device

A signature placed in SignSafe is a handwritten signature, and a declaration of intent signed in the app meets the requirements of written form. If the signature did not qualify as handwritten, the declaration is still valid in documentary form. In legal effect it is equivalent to a qualified electronic signature: both preserve written form.

Frequently asked questions

Can a developer agreement be signed in SignSafe?

No. Developer agreements require a notarial deed, which we do not compete with; they are concluded at a notary. We use SignSafe for preliminary and reservation agreements and accompanying documents.

What can a developer use SignSafe for?

For preliminary and reservation agreements, handover protocols, technical annexes not requiring a notarial deed, consents and formal correspondence. The buyer signs with a finger on a phone and the PDF goes to the account.

Can a buyer abroad sign a reservation agreement remotely?

Yes. The buyer opens a link in a browser anywhere and signs with a finger on the screen. No account and no app. A handwritten signature in SignSafe is enough for a reservation agreement under the Developer Act (documentary form alone would not be). This is a summary, not legal advice.

Can a unit handover protocol be signed on a phone?

Yes. A protocol is a PDF with fields that the buyer and the developer’s representative complete and sign on a phone or tablet. The finished file is on the account at once.

Is a SignSafe signature a qualified signature?

No. A SignSafe signature is a handwritten signature that, according to a legal opinion, meets the written form requirement (Art. 78 of the Civil Code) and is equivalent in effect to a qualified electronic signature, but it is not one, and we do not compete with that form. Where a qualified electronic signature is required (for example the electronic form under Art. 78¹ of the Civil Code), we can connect one in SignSafe. We do not compete with the notarial deed; a developer agreement is concluded at a notary. This summarises an opinion and is not legal advice.

Can a developer integrate SignSafe with its sales system?

Yes. The API lets you send documents from the developer’s system and return signed PDFs to the buyer or unit record. Pricing is individual, and we set the scope after a conversation.

How much does e-signature for a developer cost?

The standard plan costs PLN 69 net per month and includes full access and 1 GB for documents. There is a free trial at the start. The API is priced individually.

Does a SignSafe signature meet written form for developer documents?

According to the legal opinion from Gałecki and Associates dated 21 August 2023, a declaration of intent signed in SignSafe meets the written form requirement (Art. 78 of the Civil Code). This does not apply to acts requiring a notarial deed, such as a developer agreement. This is a summary, not legal advice.

What ways of signing does SignSafe offer?

Four: e-mail with a one-time code and no password, e-mail with an account password, signing on a device at a point with no login, and signing on a courier's or supplier's tablet. The scope depends on the type of document; if in doubt, consult a lawyer.
