THE MAIN POINT

The name given to a payment does not settle its effect: record the offered right, obligation, event and applicable consequence in writing.

01

Understand the obligation created by a promise

A preliminary agreement organises the commitment to conclude the intended contract under legally defined conditions. It should not be treated as an inconsequential reservation or as transfer of ownership of the lot. Article 1611 of the Civil Code establishes requirements for an enforceable promise, including writing, determination of the intended contract and fixing the relevant time by a period or condition as provided by the rule. Obtain review of the complete text before signing or paying, including attachments and documents labelled reservation, holding agreement or intention where they contain commitments. The heading on the first page does not itself establish legal effect. Ask what each party can require, what must happen before the definitive contract and what follows if an essential result is absent. Advanced negotiations may justify commitments, but these need to reflect the documents actually available. If the right offered by the seller is still unclear, establish it first instead of merely inserting the price into a template. Understanding the proposed obligation is itself part of the purchase decision.

02

Describe the property and the person becoming bound

Connect the folio, location, cadastral identity and legal description with the reviewed instruments. If the transaction concerns a share, inheritance rights or a unit dependent on earlier procedures, the agreement should state that reality and its scope. Do not write independent lot merely because a brochure assigns it a number. Identify each seller and buyer and verify representation where someone signs for another person. An intermediary who received documents or published advertising does not necessarily have authority to bind the holder. Ensure plans and other attachments are identified by date, version and relationship to the negotiated property. Where area materially determines the price, commission review of the pricing basis and consequences of discrepancies rather than assuming a standard clause resolves every measurement problem. Law 1579 connects registration with rights and instruments affecting immovable property; this helps maintain consistency between the promised transaction, the deed and the result ultimately expected in the registry. Each description should refer to the same right and the same property throughout the file.

03

Set dates and conditions that can be verified

A useful timetable distinguishes delivery of documents, outstanding decisions, payment, execution of the deed, physical possession and registration. Avoid grouping everything under completion when each stage depends on different evidence. The lawyer should verify that the period or condition meets the promise requirements and adequately determines when the intended contract must be concluded. Wording such as when the bank responds or when the seller can may leave substantial uncertainty unless drafted precisely. If lifting an attachment, succession allocation or a licensing result is awaited, identify the required instrument and scope, together with consequences if it is not obtained. Distinguish an obligation to pursue steps from a contractual undertaking to achieve a result, according to the reviewed wording. Define notification of progress, objections and changes, and the evidence each party retains. Extensions need coherent documentation; an informal conversation may leave participants following different dates. Allow for the possibility of an institution requesting further information without promising a universal processing time. The timetable should explain dependencies rather than conceal them behind one optimistic date.

04

Distinguish an advance, arras and a penalty clause

Before transferring money, ask the legal nature of each amount and where its treatment appears in the document. An advance credited against the price, arras and a penalty clause may serve different functions and should not be used interchangeably. Articles 1859 to 1861 of the Civil Code address arras, withdrawal and written expressions affecting their treatment, subject to real-estate formalities. Their application to the particular negotiations and preliminary agreement needs professional assessment. There is no universal rule that every buyer forfeits the money or receives twice the amount whenever the transaction does not proceed. The wording, nature of the payment, actual event and applicable rules matter. Require an explanation of any right to withdraw, its duration, method of exercise and relationship to other contractual consequences. If the document uses terms such as confirmatory arras or withdrawal arras, ask for a plain-language explanation consistent with every clause rather than relying on a label. The parties should understand the consequences before the money changes hands, while changes can still be negotiated.

05

Connect the purchase with your essential conditions

Write down the results you need before being obliged to proceed: acceptable title under agreed criteria, documented access, cancellation of burdens, financing or relevant planning information. Each condition needs legal review and a verifiable test rather than wording depending solely on an unexplained opinion. Bank approval does not establish that a proposed land use is permitted; a municipal enquiry does not replace title investigation. If the project requires something specific, identify the authority or document enabling assessment and the result sufficient to proceed. Do not turn the preliminary agreement into an invented certification of future construction. Ask what happens if information is unfavourable, incomplete or delivered after the expected date. If the purchaser accepts the risk of unsuccessful financing, that needs to be expressly understood; if a financing condition is negotiated, draft it consistently with payments and consequences. An attached wish list does not necessarily create contractual conditions. The adviser should connect each material dependency with an obligation, timing requirement and appropriate response, allowing both sides to understand what evidence enables the next stage.

06

Example: financing is refused after an ambiguously described payment

A purchaser pays a sum when signing a document that calls it a reservation payment on one page and arras on another. The text also includes a penalty for breach and says the balance will come from a loan, without explaining what happens if the bank refuses. Following refusal, the buyer expects a full refund while the seller believes the money may be retained. The complete document and circumstances require assessment rather than selecting whichever word favours each side. Before signing, the lawyer could have clarified the payment's nature, the financing condition, dates and relationship between withdrawal and breach. This hypothetical example does not predict who would prevail in litigation. It illustrates that identifying the intended source of funds may differ from agreeing a condition governing loan refusal. Understanding that difference makes negotiation possible before a financial dispute arises. The parties can then decide how to allocate the risk, what evidence is required and whether the proposed agreement still suits their circumstances.

07

Keep evidence of performance and amendments

A preliminary agreement needs active administration while it remains in force. Keep delivered documents, payment records, notices of objections and responses, identifying dates and recipients. If you pay a third party on the seller's instructions, obtain review and evidence connecting the transfer with the relevant obligation; not every receipt proves payment of the purchase price. When the folio, area, seller or date changes, arrange an amendment consistent with the agreement and attachments. Avoid incompatible side arrangements that make the current version uncertain. If a party fails to perform, document the facts and obtain advice before declaring consequences, offsetting amounts or abandoning a required step. Rules on default, reciprocal obligations and contractual remedies also require assessment of your own performance. A certificate showing attendance at a notary may matter within the evidence file without resolving every issue in a dispute. The objective is to demonstrate what was agreed, what occurred and what remains outstanding through complete, organised information that can be understood beyond the immediate participants.

08

Distinguish promise, deed, possession and registration

Real-estate sales require the applicable formalities, and transfer of ownership follows registration rules; signing the preliminary agreement does not replace those results. Article 1857 of the Civil Code and articles 12 to 17 of Decree 960 explain the role of the public deed, while Law 1579 addresses registration and qualification. Arrange final review of the instrument, burdens, parties' identity and required supporting evidence before execution. Afterwards verify filing and the registered result, and document physical possession according to the agreed conditions. Holding keys does not establish registration of the intended acquisition. Keep payments connected to the reviewed sequence and preserve the complete file for future sales or claims. This guide received editorial review on 14 October 2026 and provides orientation on civil preliminary agreements in Colombia. Validity, interpretation and consequences of a specific document require professional examination of its text, background and applicable framework, including additional rules where the transaction involves them. The final wording should reflect the actual deal rather than assumptions carried over from another property's contract.

Commitment and payment review sheet

This table compares functions and review questions rather than supplying clauses ready for signature. Record the draft’s exact wording and have its effects checked against the offered interest and timetable.

Review questionEvidence to recordNext action
Which contract and interest are promised?Parties, authority, property or share, price and documents identifying the promised object.Compare the draft with title records and attachments; settle the object before discussing only the signing date.
Does the text establish an ascertainable time?Written period or condition, relevant event, outcome evidence and each party’s preceding commitments.Have determinacy and consequences of a failed event reviewed; avoid assumed dates.
Is the payment an advance, arras or a penalty?Term used, written function, credit against price and relationship with the document’s other clauses.Ask for its actual effect to be explained; the word reservation alone does not establish forfeiture or double repayment.
Is withdrawal allowed, and how does it relate to breach?Wording of the right, exercise, agreed limit and separate consequences provided for breach.Review consistency and application examples; do not confuse valid withdrawal with every form of breach.
What happens if an essential condition is absent?Required document, responsible party, payment condition, refund rule and method for evidencing the outcome.Check continuation and exit scenarios with the adviser before transferring funds.
