Buying or selling an apartment rarely happens in one step. It usually starts with interest in the property, continues with an agreement on price and key terms, and only then moves to the formal transaction documents. At this stage, many buyers and sellers ask what the difference is between an earnest money agreement and an apartment sale agreement, and which document should be used first.
Both documents relate to the same apartment sale, but they serve different purposes and are used at different moments. If that distinction is unclear, misunderstandings can quickly arise around payments, deadlines, property handover, or each party's obligations.
In this article, we explain:
- what an earnest money agreement is and when it is used,
- what an apartment sale agreement is and why it matters,
- how these documents differ in practice,
- when you need one document and when you need the other,
- and how Doqubit helps prepare apartment sale documents in a clear, structured way for both parties.

What is an apartment earnest money agreement?
An apartment earnest money agreement is an agreement where one party gives the other a certain amount of money as confirmation that both parties seriously intend to complete the apartment sale transaction.
Earnest money is not just a simple advance payment. It also works as security for the parties' obligations. If one party withdraws from the transaction, the earnest money may be forfeited or returned in double the amount, depending on the situation and the terms written into the agreement.
In practice, an earnest money agreement is used when the buyer and seller have agreed on the main terms, but the apartment sale agreement is not yet ready to be signed. This often happens when more time is needed for bank financing, document preparation, property checks, or clarifying other transaction details.
An earnest money agreement helps record:
- the transaction price,
- the amount of earnest money,
- the deadline for signing the sale agreement,
- the property details,
- and the parties' responsibilities until the final transaction is completed.
Signing an earnest money agreement does not transfer ownership of the apartment. It confirms the parties' intention to complete the transaction later. Ownership changes only after the sale agreement is signed and the change is registered in the Land Register.
What is an apartment sale agreement?
An apartment sale agreement is the document that formally records the apartment sale transaction between the seller and the buyer.
It sets out in detail:
- what is being sold,
- the agreed purchase price,
- how payment will be made,
- when and how the apartment will be handed over,
- and each party's duties and responsibilities.
Unlike an earnest money agreement, this document is about completing the transaction, not only preparing for it.
The apartment sale agreement available in Doqubit is intended for standard situations where the transaction is made directly between buyer and seller without mortgage financing involvement. In such cases, the agreement helps set out the deal clearly and transparently. The document is prepared through a guided process, so the user does not need to guess what clauses to include. Doqubit asks the relevant questions step by step and turns the answers into a structured document.

When do you need an apartment earnest money agreement?
An earnest money agreement for buying an apartment is useful when the transaction is not yet ready to close, but both parties want to secure what has already been agreed. At this stage, the document helps confirm the parties' intention and define clear obligations before the final sale agreement is signed.
The agreement usually states the earnest money amount, payment terms, and the deadline by which the parties plan to sign the apartment sale agreement. The key point is that earnest money acts as security: if one party withdraws, the financial consequences can be agreed in advance and written into the document.
Still, an earnest money agreement should not be treated as a formality. In real estate transactions, not every preliminary agreement leads to a completed sale. Circumstances can change, financing can take longer than expected, or other obstacles can prevent the transaction from moving forward.
When do you need an apartment sale agreement?
An apartment sale agreement is needed when the parties are ready to formally complete the transaction. This means the price has been agreed, payment terms are clear, and both sides understand and accept the property handover conditions.
At this stage, the sale agreement becomes the central document for the transaction. It records the parties' details, apartment and cadastral data, purchase price, payment procedure, and the conditions for delivery and acceptance of the property. Even if earnest money has already been paid or the parties have agreed orally, the sale agreement defines how the transaction works in practice.
A sale agreement needs clear structure, not only correct information. Doqubit helps turn the parties' agreement into a readable document where the terms are arranged in a logical order and can be reviewed easily by both sides.

Common mistakes in apartment sale documents
In practice, problems in apartment transactions often arise not because of the transaction itself, but because the wrong document is used at the wrong time or the parties do not fully understand what each document does.
One common mistake is assuming that an earnest money agreement is already a full sale agreement. It can secure a preliminary arrangement, but it does not replace the sale agreement as the main transaction document.
Another frequent issue is failing to describe what happens if the agreement is not performed or if a dispute appears. If those situations are not clearly addressed in writing, each party may later interpret the same events differently.
A third problem is relying on random templates found online. A generic template may not match the specific apartment transaction or may leave out important details. To understand this better, read Doqubit's article about the risks of using contract templates.
