Electronic signature at a real estate agency: How to sign a purchase contract online
2026-06-18 | 11 min News
A real estate purchase contract, reservation contract, rental contract or handover protocol doesn't have to wait for a personal meeting, printing and scanning. See how electronic signature via OKdokument can help real estate agencies speed up document signing, get a better overview of the signature status and reduce administration when selling and renting real estate.
The reality of signing contracts in real estate
In a real estate transaction, the signature is often the final step, but also one of the slowest. A reservation agreement, brokerage agreement, real estate purchase contract, lease agreement, addendum or handover protocol can be prepared quickly. The client agrees to the terms, the real estate agent has the document ready and the transaction can move forward. Then, however, the signature comes — and the process suddenly comes to a halt because of printing, scanning, an in-person meeting or waiting for the other party.
The deal is agreed, but the signature slows it down. In real estate, time is a sensitive factor. A prospective buyer may be considering several properties, the seller expects quick progress and the landlord does not want to wait until the tenant gets to a printer. Each extra day can increase the risk that the client decides differently, a competing offer appears or the agreed process starts to become complicated.
The most common delays arise in simple steps:
- the client does not have time to come to the real estate office,
- one of the parties is out of town or abroad,
- the document has to be printed, signed and scanned,
- the wrong version of the document is signed,
- the real estate agent has to repeatedly chase the signature or search for the final version.
Electronic signing through OKdokument helps shorten the time between agreement and the signed document. The real estate agency can send the document to the client online, request a remote signature and work with the final signed version without printing, scanning and manually chasing signatures. This way, the signature does not become an obstacle to the deal, but a natural continuation of digital communication with the client.
Where real estate agencies lose time when signing documents
The document is ready. The client agrees. The real estate agent only needs the signature.
And this is exactly where a real estate transaction often slows down unnecessarily. Not because the document is complicated, but because a small logistics operation begins to form around the signature: who will come to the office, who has a printer, who will scan the document, who will send it back and whether the correct version has been signed.
In real estate practice, the signature is most often delayed in these situations:
- the client is out of town or abroad,
- the seller and buyer do not have a shared available time slot,
- the tenant deals with the document only after work,
- the document is sent back and forth by e-mail,
- the real estate agent has to check versions and chase the signature,
- the signed document arrives as a low-quality scan or photo.
With one document, it may seem like a small thing. With several properties, clients and deals in progress, it becomes repeated administration that takes time from both the real estate agent and the client.
The signature is not the problem. The problem is the process around the signature. If signing is moved online, the document does not have to leave the digital environment and the real estate agency has greater control over where the deal currently stands.
How electronic signatures work for real estate contracts
Electronic signatures in real estate processes do not have to mean any complex IT solution. In the simplest scenario, the real estate agent prepares the document as before — for example, a reservation agreement, brokerage agreement, draft real estate purchase contract, rental agreement or handover protocol — and instead of printing it, sends it for signature online.
The process is simple:
- Upload the document
In OKdokument, you insert the prepared contract, protocol or other document that the client is to sign. - Enter the signer’s e-mail address
You add the contact details of the client, buyer, seller, tenant or landlord. - Send the document for signature
The signer receives an e-mail with a link to the document.
On the client’s side, the process is even simpler. They open the link, check the document and sign it online. They do not have to create an account, install anything or deal with technical settings. They can also sign the document from a mobile phone, for example between meetings, from home or from abroad.
No installation, no complications. For the real estate agency, this means obtaining the signature faster, less administration and a better overview of the document’s status.
Which real estate documents can you sign online?
Electronic signatures make sense for documents that a real estate agency repeatedly sends to clients, owners, prospective buyers or tenants for signature. Typically, these are documents where the signature should not unnecessarily slow down the sale, purchase or rental of a property.
Online signing can be used, for example, for these documents:
- reservation agreement,
- brokerage agreement,
- real estate purchase contract or its draft,
- property rental agreement,
- lease agreement,
- addenda to contracts,
- acceptance and handover protocol,
- consent to the processing of personal data,
- confirmation of cooperation terms,
- protocol on the status of utilities, equipment or handover of the property.
The greatest benefit arises for documents that are signed remotely, between multiple parties or under time pressure. For legally sensitive documents, official acts or documents requiring a specific form of signature, it is always advisable to verify what type of electronic signature is required for the given purpose.
Signing a real estate purchase contract or rental agreement from anywhere
Real estate transactions today are often handled remotely. The client lives in another city, the seller works abroad, the buyer is on holiday or the landlord manages an apartment outside the place where the property is located. With a paper signature, this immediately creates a complication: the document must be printed, signed, scanned, sent back and checked.
With an electronic signature through OKdokument, the signature is not tied to the office, a printer or an in-person meeting. The real estate agent sends the contract or protocol online and the client can sign it wherever they are — from a computer, tablet or mobile phone. This is especially important for documents that need to be concluded quickly, for example a reservation agreement, rental agreement, addendum or confirmation of cooperation terms.
In practice, this helps especially in situations where:
- a prospective buyer is out of town but does not want to lose the property,
- the seller lives or works abroad,
- the tenant needs to sign a rental agreement before moving in,
- the landlord manages multiple properties remotely,
- multiple parties sign the document from different places,
- the real estate agent needs to move the deal forward without waiting for an in-person meeting.
The advantage is not only client comfort. For the real estate agency, this means a smoother business process, fewer rescheduled appointments and less risk that an unnecessary delay appears between agreement and signature. The signature is no longer tied to a place — it can take place when the client is ready to sign, not only when they get to a printer or office.
Faster closing of real estate deals
In real estate, there is a brief moment when the client has decided. They like the apartment, agree to the terms, want to reserve the property, proceed to purchase or confirm the rental. That is precisely when it is important not to slow the process down with administration.
If the client is supposed to sign the document later, room for doubt arises. They hesitate. They consult someone else. They look at another offer. They start discussing the price, date or terms again. Not always because they do not want to sign — often only because an unnecessary pause has appeared between the decision and the signature.
Electronic signatures help use the moment when the client is ready to act
With a reservation agreement, agreement on rental terms or brokerage agreement, the real estate agent can send the document for signature immediately. The client opens it online, checks it and signs it without having to wait for a meeting, a printer or another day at the office.
The difference is simple:
| Paper process | Online signature through OKdokument |
| “I will send you the document; print it and send it back.” | “I am sending you a link; you can sign right away.” |
| the signature is postponed until later | the signature takes place at the moment of decision |
| more room for hesitation | faster transition to commitment |
| the real estate agent has to chase | the real estate agent tracks the signature status online |
The speed of the signature is the speed of the deal. The more easily the client moves from agreement to signature, the lower the risk that the deal gets stuck on administration instead of moving on to the next step.
More real estate documents in one signing process
A real estate transaction usually does not depend on just one document. For one property, there may be a reservation agreement, an addendum to an agreement, a consent, a handover protocol or other attachments. For a rental, it may include a rental agreement, handover protocol and confirmation of the condition of the equipment. If each document is sent separately, an unclear chain of e-mails, attachments and versions quickly emerges.
Electronic signing helps combine multiple documents into one clear process. The real estate agent does not have to send each document separately and track what has already been signed and what is still missing. Documents can go for signature together — in one signing envelope, with a clear order and one smooth process for the client.
Typically, this makes sense for a package of documents such as:
- reservation agreement + related attachments,
- rental agreement + handover protocol,
- addendum + confirmation of new terms,
- brokerage agreement + consent to data processing,
- handover of the property + protocol on the status of utilities or equipment.
For the client, it is simpler: they open one link, go through the documents and sign them in one process. For the real estate agency, it is clearer, because it has a clearly visible overview of which documents have been signed, which are still pending and where the process currently stands.
The result is less chaos in e-mails, fewer lost attachments and greater certainty that the entire document package has been closed correctly.
Overview of signature status with multiple parties
With paper or e-mail signing, the real estate agent often does not know what is currently happening with the document. The client may have opened it. Maybe they have not even seen it yet. Maybe they have already signed it but forgot to send it back. Or maybe it is waiting for the other party, who does not know about it.
It is precisely this lack of visibility that creates unnecessary work. The real estate agent has to call, write reminders and ask questions that the system could show automatically.
“Have you already signed the contract?”
“Did you receive the document?”
“Are you having trouble opening the attachment?”
“Are we still waiting for the landlord’s or tenant’s signature?”
With electronic signing through OKdokument, the real estate agency has a better overview of the document’s status. It can see whether the document has been sent, who has to sign it, who has already added their signature and where the process has stopped. This is useful especially for multi-party documents, for example when both the buyer and seller sign, the landlord and tenant sign, or multiple co-owners sign.
Instead of searching through e-mails, the real estate agent has a clearer status of the signing process:
| What the real estate agent needs to know | Why it matters |
| Who has already signed | the deal can move to the next step |
| Who has not signed | the urgency is directed to the right person |
| Where the process has stopped | the real estate agent is not handling the entire document blindly |
| Which version is final | no chaos arises in attachments and scans |
You no longer have to call the client just to ask: “Have you signed?” Instead, you see the signature status online and know how to respond exactly where it is needed.
Legal validity and security of electronic signatures
With real estate documents, it is not enough for the signature to be fast. It is also important for the real estate agency to be confident that the signed document is usable, traceable and protected against subsequent changes.
Electronic signatures in the EU are governed by the eIDAS Regulation. It distinguishes between different types of electronic signatures and at the same time states that an electronic signature cannot be denied legal effect or admissibility as evidence solely because it is in electronic form.
In practice, this means that for documents such as reservation agreements, brokerage agreements, rental agreements, consents or protocols, not only the signature itself is important, but also evidence of the process. OKdokument helps create an audit trail: who signed the document, when they signed it and what stage the signing process was in. At the same time, it protects the final signed version of the document so that its content cannot be changed unnoticed after signing.
For the real estate agency, this is a practical combination of speed and certainty. Instead of a paper contract, scan and e-mail attachment, you work with a digital document where you have a better overview of the signing process and the final version.
Electronic signatures therefore help achieve similar evidentiary value to paper in ordinary real estate processes — without printing, scanning and unnecessary administration.
For legally sensitive documents, official acts or documents for which the law, land registry, bank, lawyer, notary or the other party requires a specific type of signature, it is advisable to verify the requirements in advance. Especially with the final real estate purchase contract, additional requirements regarding form, signature verification or document delivery may also enter the process.
Less paperwork, more closed deals
A real estate agency does not earn money by coordinating printing, scans and the signing of attachments. It earns money by being able to move the deal quickly and reliably from interest to agreement, from agreement to signature and from signature to the next step.
Electronic signing through OKdokument helps remove unnecessary downtime from real estate processes. The client does not have to come to the office in person, the document does not have to wait for a printer and the real estate agent does not have to search for which version has been signed. Instead, they can send the document online, track the signature status and work with the final signed version.
The result is simple: less waiting, less administration and more space for closing deals. For documents such as a real estate purchase contract, rental agreement, reservation agreement, brokerage agreement or handover protocol, a faster signature can significantly shorten the time between agreement and the next step in the deal.
