There is a document that precedes everything when you buy property off-plan — and most buyers never ask to see it.
Real Estate Registration formalizes the development project legally. Without it, the developer cannot and should not advertise the units. With it, you have access to information that no sales presentation will voluntarily show.
This guide explains what it is, what it contains, and how you check it before signing.
What is Real Estate Registration?
Real Estate Registration (Registro de Incorporação, or RI) is the act through which a developer formally registers a development project with the Property Registry Office (Cartório de Registro de Imóveis). It is regulated by Law 4.591/1964 (Real Estate Incorporations Law).
RI creates the development legally. Before RI, the project exists only as a plan — on paper, at city hall, in the financing. With RI, the development exists legally, the units have legal identification, and the developer can begin sales.
Law 4.591/1964 is explicit: it is prohibited to advertise any real estate development without the RI being registered with the competent property registry office (Article 32 and Article 66). The real estate agent and agency participating in the advertisement are also subject to this prohibition.
If the development does not have RI, the incorporation does not exist. If the incorporation does not exist, what is being sold is something else — and it matters to know what.
What is Included in Real Estate Registration?
RI is not a single document — it is a collection of documents filed and registered with the property registry office. Law 4.591/1964 (Article 32) lists the required documents:
Land documents:
– Title of ownership of the land (deed, registration)
Project documents:
– Construction plans approved by city hall
– Building permit issued
Development documents:
– Descriptive memorial of construction specifications (finishes, materials, installations)
– Schedule of unit areas (private area, common area, and total area of each unit)
– Floor plan of each unit, indicating position on the floor
– Site plan showing the development layout
Developer documents:
– Declaration of grace period (if applicable)
– Negative certificate of labor and tax debts of the developer
Financial documents:
– Total cost of construction, with financial schedule
– Declaration of constructor responsible for the work
The buyer has the right to access any of these documents by requesting a certificate from the property registry office. RI is public.
Why RI Protects the Buyer
RI transforms promises into formal obligations registered with the property registry office.
Registered descriptive memorial: what is in the RI is what will be delivered. If the developer wants to change specifications after registration — swap cladding, modify finishes, alter common areas — they must register an amendment to the RI and notify all buyers. Unregistered changes constitute breach of contract.
Binding area schedule: the private area shown in RI is the area you will receive. Variations above 5% authorize the buyer to rescind the contract (Article 43 of Law 4.591/1964).
Enforceable delivery deadline: the delivery deadline stated in the contract, tied to RI, is the deadline that can be enforced legally. Without RI, there is no formal registered deadline.
Foundation for Fiduciary Fund Protection: developments with RI can opt for Fiduciary Fund Protection (Patrimônio de Afetação) (Law 10.931/2004). Without RI, no fiduciary protection is possible.
How to Consult Real Estate Registration
Step 1: Ask for the RI Number
Ask the real estate agent, the developer, or the agency directly: “What is the Real Estate Registration number and which property registry office is it registered with?” The answer should be immediate — it is a registration number and the name of the property registry office.
If the answer is hesitant, evasive, or if they say “it is still in the registration process,” that is a red flag. Do not sign anything before you have the RI number.
Step 2: Locate the Property Registry Office
RI is registered with the Property Registry Office (Cartório de Registro de Imóveis) of the district where the land is located. In Florianópolis:
- 1st Property Registry Office of Florianópolis — covers part of the island and the mainland area
- 2nd Property Registry Office of Florianópolis — covers another part of the island
- Property Registry Office of São José or Palhoça — for developments in the metropolitan area
The real estate agent or developer knows which property registry office has the RI. If they don’t know, that is another red flag.
Step 3: Consult the Registration
With the RI number and property registry office identified:
In person: go to the property registry office and request a certificate of the land registration with all entries. Provide the RI number. The office issues the certificate upon payment of fees (amount varies, typically under R$ 100,00).
Online: many property registry offices in Santa Catarina already offer online consultation via the CRIE portal (State Property Registry Center) or the office’s own portal. Check the website of your identified office to verify if this service is available.
What to Verify in the Registration Certificate
In the registration certificate, look for:
– The entry of Real Estate Registration (number, date, book)
– Whether there is an entry for “Fiduciary Fund Protection Regime” or reference to Law 10.931/2004 (Fiduciary Fund Protection)
– Whether there are liens on the land that may affect the construction (mortgage, fiduciary sale)
– Whether the area and land data match what is shown in the sales materials
What It Means to Have No RI
If the development does not have RI, there are some possibilities:
RI is pending: some developers begin sales before registration, using a “reservation phase” as justification. This violates Law 4.591/1964 (Article 32). Buying in this phase means buying without RI protections — without a binding descriptive memorial, without a formal deadline, without foundation for fiduciary fund protection.
The product is an SPE: an SPE (Special Purpose Entity) does not have and cannot have RI, because it is not an incorporation. If there is no RI and the seller says it is “a different model” or “works like a construction condominium,” it is an SPE — with all the implications of that structure.
The development is irregular: it has no approval, no building permit, cannot be registered. This scenario is rare in formally marketed developments, but it exists.
In any of these cases, signing any document before RI is assuming risks that the law created RI specifically to eliminate.
Frequently Asked Questions
Does Real Estate Registration guarantee delivery of the property?
Not directly. RI formalizes the development and creates legal obligations for the developer. Delivery guarantee depends on the company’s financial strength and the existence of Fiduciary Fund Protection. RI is a necessary condition for protections to exist — it is not itself a guarantee of completion.
Can I sign a reservation contract before RI?
Formally, Law 4.591/1964 prohibits sales before RI. In practice, the market uses “reservation” or “proposal” as a pre-RI mechanism, with no significant payment obligation. If any amount is paid (even a deposit) before RI, that is a sale without registration — and it creates risks for the buyer.
How long does it take for RI to be registered?
It depends on documentation and the property registry office. Developments with complete documentation can have RI registered in 15 to 60 days. Longer delays typically indicate documentation gaps — building permit not yet issued, expired certificates, developer’s pending issues.
Is RI the same as the certificate of occupancy (habite-se)?
No. RI exists before construction — it is the document that authorizes sales and formalizes the project. Certificate of occupancy (habite-se) is issued by city hall after construction is completed, confirming that the building complies with the approved plans.
Verify Before Signing
Real Estate Registration is the first filter. If a development passes this filter — RI registered, detailed descriptive memorial, Fiduciary Fund Protection recorded — the remaining checks become simpler.
Regente applies this filter to every launch we evaluate. In 27 years, none of the developments we intermediated was from a developer without current RI or that failed to deliver.
If you are evaluating a launch and want to know if RI is in order, speak with a Regente real estate agent.
