Key functions of the lawyer in the purchase of a property
Having a lawyer when buying real estate protects the buyer at every stage of the transaction, from verifying the legal status of the property to the final entry in the registry.
- Review of the property's legal status: Verifies that the property is free of mortgages, attachments or legal disputes.
- Title search (estudio de títulos): Examines the property's history in order to detect possible irregularities. If the registry history needs to be extended beyond twenty years, the Oficina de Registro (public deeds registry office) issues a special certificate for that purpose (Ley 1579 de 2012, art. 69).
- Contract advice: Drafts and reviews the purchase and sale agreements in order to protect the buyer's interests.
- Handling of notarial and registry formalities: Coordinates the signing of the escritura pública (public deed) and its entry in the Oficina de Registro de Instrumentos Públicos.
- Tax advice: Explains the taxes and costs associated with the transaction.
Mortgage loans and tax aspects
If the purchase is made through a mortgage loan, the lawyer reviews the terms and conditions of the loan closely in order to detect and avoid abusive clauses. The lawyer also advises on the taxes associated with acquiring the property:
- Registration tax.
- Property tax.
- Withholding tax (retención en la fuente) in specific cases.
Stages of the purchase process with legal advice
Before formalizing any purchase commitment, the lawyer carries out legal due diligence in order to make sure the property has no legal problems. This includes requesting the Certificado de Tradición y Libertad (the property's title and encumbrance certificate), which shows the property's history and confirms who the legitimate owner is.

The Certificado de Tradición y Libertad reproduces the legal situation of the property and, in computerized offices, is issued immediately (Ley 1579 de 2012, arts. 67 and 68). Its validity is limited to the date and time of the request (art. 72), so it is best to obtain it shortly before signing.
- To confirm that the property does not have mortgages, liens or pending litigation.
- Check that the property taxes and other contributions are up to date.
- Verify that the property complies with the regulations of urban planning.
Before the deed, a promesa de compraventa (binding pre-sale agreement) is usually signed. The purchase and sale agreement must include the identification of the parties, a description of the property, the price and the method of payment, and penalty clauses for breach. The lawyer reviews every clause in order to make sure it is fair and protects the buyer.
For the promesa to bind the parties, article 89 of Ley 153 de 1887 requires that it be in writing, that it set a time limit or a condition for the date of the final contract, and that the property be identified in such a way that only the transfer of title or the legal formalities remain in order to complete it.
In this case, several people signed a private agreement to formalize by escritura pública a community of ownership and possession over a property, but the document never specified on what legal basis that transfer would be made. The lower courts declared the absolute nullity of the promesa contract because the promised contract was left undetermined, and the Corte Suprema upheld that decision. The Court was emphatic that the underlying error was confusing the escritura pública (the instrument) with the legal act that had to be solemnized through it: it is not enough to promise to "record a deed"; the promesa must make clear which specific legal transaction that deed will document. CSJ SC490-2024 — the promised contract left undetermined.
Once the sale has been agreed, it must be formalized before a notary's office by escritura pública. The lawyer coordinates the signing of the deed before the notary, verifies payment of taxes and notarial fees, and handles registration of the property with the Oficina de Registro de Instrumentos Públicos, which formalizes the transfer of ownership.
The escritura pública is a requirement without which the sale of real estate is not perfected (Código Civil, art. 1857). The subsequent entry in the Oficina de Registro de Instrumentos Públicos effects the transfer of ownership (Código Civil, art. 756) and, as a general rule, the registration process must be completed within a maximum of five business days from filing (Ley 1579 de 2012, art. 27).
The buyer must pay certain taxes and costs associated with the transaction. The lawyer advises on these payments and makes sure everything is in order before completing the purchase.
- Registration tax (impuesto de registro): Required in order to register the property in the new owner's name.
- Property tax (impuesto predial): Must be up to date before the purchase.
