When you sign to buy an off-plan property, there is a question that rarely anyone asks at the right moment: are you buying a real estate unit or a company share?
The answer is not bureaucracy. It determines whether the price you signed is what you will pay, whether you can use the FGTS, what happens to your money if the builder has problems — and how you exit the deal if you need to before delivery.
This guide places both models side by side. But first, it is necessary to clear up a confusion that the market rarely clarifies: there are two completely distinct uses for the acronym SPE in the real estate market.
What is conventional incorporation
Conventional incorporation is the dominant model in the Brazilian real estate market and what most buyers assume they are acquiring when talking about “buying off-plan”.
In this model, an incorporator — a company registered and responsible for the enterprise — performs the Incorporation Registration (RI) at the Real Estate Registry Office before starting sales. This registration formalizes the enterprise with:
- The complete descriptive memorial (technical specifications, finishes, common areas)
- The area chart individualized by unit
- The draft of the future purchase and sale contract
What this means for the buyer:
You enter into a purchase and sale contract with the incorporator. The price is fixed. The registered memorial legally binds what will be delivered. You are a creditor of the incorporator — it has the obligation to deliver the property as promised, within the agreed timeframe, at the contracted price.
If the incorporator fails to comply, you have a clear contractual basis to sue.
Law 4.591/1964 (Condominiums and Incorporations Law) regulates this entire process and establishes buyer protections. In enterprises with Fiduciary Fund Protection (Law 10.931/2004), the property under construction is legally separated from the incorporator’s estate: if it fails, the project continues — buyers are privileged creditors, with preference over banks and other creditors.
The two uses of SPE in the real estate market — and why the distinction matters
Before comparing SPE and conventional incorporation, it is necessary to clear up a frequent confusion.
SPE is the acronym for Sociedade de Propósito Específico — a legal entity created for a single objective. In the real estate market, SPE appears in two radically distinct forms, and treating both as if they were the same leads to serious evaluation errors.
SPE as an incorporation vehicle (legitimate)
The incorporator creates an SPE to be the legal vehicle of the enterprise. This SPE conducts a conventional incorporation: registers the Incorporation Registration (RI) at the Real Estate Registry Office, notes the Fiduciary Fund Protection, and sells units with purchase and sale contracts. The buyer signs a purchase and sale contract for a specific unit — with a fixed price, defined timeframe, binding descriptive memorial.
For the buyer, this model is equivalent to buying from any conventional incorporator. It can even be safer: since the SPE exists exclusively for that enterprise, the estate is naturally segregated from the parent company from the outset.
This use of SPE is common, healthy, and legal. Many of the most solid enterprises in the market are structured this way.
SPE of shares — “cost price” (the problematic model)
Here the buyer does not buy a real estate unit. The buyer purchases shares of the company that will build the enterprise. The promise is that these shares will be converted into units at the end of the work. There is no RI because there is no incorporation — there is a company building, and you are a partner in it.
The most common commercial name is “cost price”, “construction condominium” or “cost regime”. The marketing logic is that the buyer pays only the cost of the work, without the incorporator’s profit margin. What the name does not say is what changes structurally: you are not a buyer, you are a partner.
The criterion that separates the two models:
| SPE of incorporation | SPE of shares (“cost price”) | |
|---|---|---|
| Is there an Incorporation Registration? | Yes | No |
| What the buyer acquires | Real estate unit | Company share |
| Document signed | Purchase and sale contract | Contract for acquisition of shares |
| The buyer is | Creditor | Partner |
| Fiduciary Fund Protection | Applicable | Not applicable |
| Price | Fixed | Variable |
The question that resolves it in practice: “What am I signing — a purchase and sale contract for a unit or a share acquisition contract?” If it is a share, everything that follows in the next sections applies to your case.
This guide compares conventional incorporation (including incorporations carried out by SPEs with RI) with the SPE share purchase model.
Complete comparison: conventional incorporation vs. SPE share purchase
1. What you are legally
| Incorporation | SPE | |
|---|---|---|
| Position | Buyer / creditor | Partner / shareholder |
| Relationship with the builder | Contractor (you sue) | Shareholder of the same company |
| Main document | Purchase and sale contract | Contract for acquisition of shares |
In incorporation, there is a clear legal relationship: you sue and the incorporator delivers. In SPE, you and the builder are on the same side of the table — both are the company.
2. Final price
| Incorporation | SPE | |
|---|---|---|
| Price | Fixed in contract | Variable according to actual cost of work |
| If cost goes up | Incorporator’s problem | Divided among shareholders |
| Mechanism | Purchase and sale contract | Capital calls |
The fixed price of incorporation is real protection. In SPE, the initial budget is an estimate. If the cost of work exceeds the forecast — due to material increases, labor costs, unforeseen events or planning errors — shareholders are called to contribute additional capital. This call is the capital call and can occur more than once.
3. Use of FGTS
| Incorporation | SPE | |
|---|---|---|
| FGTS during construction | Applicable (under conditions) | Not applicable |
FGTS can only be used to purchase real estate. In SPE, what you acquire is a company share — not a property. FGTS is not applicable during the construction phase. For those counting on FGTS as part of the purchase capital, this eliminates a relevant source of resources.
4. Bank financing
| Incorporation | SPE | |
|---|---|---|
| Financing during construction | Not available (market standard) | Not available |
| Financing after delivery | Yes, via individualized registration | Yes, after endorsement |
| Timeframe for post-delivery endorsement | Relatively straightforward | Longer and more costly process |
Both models do not allow conventional bank financing during the construction phase — banks finance properties with registrations, not ongoing construction. The difference lies in what happens after delivery.
In incorporation, individualization of registrations is a relatively straightforward process. In SPE, it is necessary to:
1. Register the property in the SPE’s name (the company as owner)
2. Transfer ownership of each unit to each shareholder
3. Pay ITBIITBIVer tudo → on that transfer
4. Individualize the registrations
This process can take months. Until then, there is no registration to finance or advertise.
5. Descriptive memorial
| Incorporation | SPE | |
|---|---|---|
| Registration | Registered at notary, binding | Can be altered by shareholder vote |
| What you receive | What was promised and registered | What shareholders approve during construction |
In incorporation, the descriptive memorial registered in the RI binds the delivery. If the incorporator alters what was promised, there is breach of contract.
In SPE, the memorial can be altered by shareholders’ deliberation. If the majority decides to replace the planned finish or reduce common area specifications, this can be done without constituting breach — you voted on what you received, even if the vote was by the minority.
6. Responsibility for construction liabilities
| Incorporation | SPE | |
|---|---|---|
| Work accidents | Incorporator’s | Potentially shareholders’ |
| Labor liabilities | Incorporator’s | Potentially shareholders’ |
| Supplier debts | Incorporator’s | Potentially shareholders’ |
Construction generates liabilities: accidents, employees, taxes, suppliers. In incorporation, these liabilities belong to the incorporator — the buyer has no link to them. In SPE, you are a partner of the company that generated them. Depending on the SPE’s legal structure and what occurs, shareholders can be liable for construction management liabilities.
7. Liquidity — how you exit before delivery
| Incorporation | SPE | |
|---|---|---|
| Exit instrument | Assignment of rights (simpler) | Assignment of shares (more complex) |
| Process | Assignment contract between parties | Alteration of corporate bylaws + shareholder consent |
| Buyer market | Broader | More restricted |
| Price trend | Greater negotiating power | Frequently at a discount |
In incorporation, assignment of rights is a relatively common operation and the buyer market is broader — any individual or legal entity can acquire purchase rights for a property.
In SPE, selling your position means assigning shares of a company. The potential buyer assumes all the risks described above, including future capital calls. The pool of interested parties is smaller, negotiating power lies with the buyer, and the process is more bureaucratic.
8. Protection in case of bankruptcy
| Incorporation | SPE | |
|---|---|---|
| With Fiduciary Fund Protection | Buyers are privileged creditors, above banks | Shareholders respond as partners |
| Without Fiduciary Fund Protection | Buyers join the creditor queue | Shareholders respond as partners |
Fiduciary Fund Protection (Law 10.931/2004) is the most robust protection mechanism available in the Brazilian real estate market. It separates the enterprise’s estate from the incorporator’s general estate: if the company fails, buyers’ money cannot be used to pay other company debts. The project continues or buyers have preference in the bankruptcy proceedings.
This mechanism exists in conventional incorporation — not in SPE. As a shareholder, you are not a creditor of the company: you are the company.
9. Capital calls
Exclusive to SPE. In incorporation, the price is fixed and construction unforeseen events are absorbed by the incorporator. In SPE, every cost increase is divided among shareholders.
The shareholder who lacks liquidity to meet a capital call faces three paths:
– Contribute capital even without prior planning
– Have their participation diluted (other shareholders who contribute get a larger share)
– Sell the share urgently, frequently below the invested value
10. Legality of the advertisement
| Incorporation | SPE | |
|---|---|---|
| Can be advertised as “property” | Yes | No — it is a company share |
| Requires Incorporation Registration to advertise | Yes (Law 4.591/1964, Article 66) | Not applicable (does not have RI) |
| Advertisement as “apartment for sale” without RI | Illegal | Illegal (and deceptive) |
This is the most ignored dimension in the comparison between the two models.
When an SPE is advertised as “off-plan apartment” or “property for sale”, what is being offered is not a property — it is a company share. The two have completely distinct legal natures.
Advertising a share as property can simultaneously constitute:
- False advertising (CDC, Article 37): any publicity capable of misleading the consumer regarding the nature of the product is prohibited. A share is not property.
- Crime against the popular economy (Law 1.521/1951): commercial practices involving fraud or false information in economic relations are typified as crime. Penalty: detention of 2 to 10 years.
- Violation of the Incorporations Law (Law 4.591/1964, Articles 65-66): it is prohibited to advertise incorporation without Incorporation Registration. SPE has no RI — therefore, any advertisement presenting it as a “real estate launch” is illegal.
Responsibility can reach the SPE structurer, the administrator, the broker and the real estate agency that intermediated the advertisement.

What the law says about each model
Conventional incorporation: regulated mainly by Law 4.591/1964 (Condominiums and Incorporations Law). This law defines the obligations of the incorporator, the Incorporation Registration, buyer protections and what happens in case of breach. Law 10.931/2004 added Fiduciary Fund Protection. Law 13.786/2018 (Distrato Law) established the conditions for contract rescission.
SPE: there is no specific law for real estate SPE. The structure is governed by the Civil Code (corporate bylaws of a limited liability company) and the bylaws of the SPE itself. This means that buyer protections depend on what was negotiated and is written in the share acquisition contract — not on a law that guarantees them systematically.
This difference IS essential: in incorporation, the law protects the buyer regardless of what the contract says. In SPE, protection is what the contract says — and the contract was drafted by whoever structured the SPE.
How to identify the model before signing
Three direct questions:
1. Is there an Incorporation Registration?
Ask for the RI number at the notary. If there is no RI — only an SPE corporate bylaws — it is SPE. An RI registered with descriptive memorial confirms conventional incorporation.
2. What are you signing?
“Purchase and sale contract” → incorporation. “Contract for acquisition of shares” or “participation instrument” → SPE.
3. Is the price fixed?
Ask directly: “Can the price be altered after signing?” If the answer is anything other than “no” — if there is mention of “cost adjustments”, “allocations” or “calls” — it is SPE.
If the answer to any of these questions is ambiguous, request written confirmation before signing.
Frequently Asked Questions
Is SPE with Fiduciary Fund Protection safer?
SPE and Fiduciary Fund Protection are distinct concepts. A conventional incorporation can and should have Fiduciary Fund Protection. An SPE can mention Fiduciary Fund Protection, but the fundamental structure does not change: the shareholder is still a partner, not a creditor. Separately verify whether there is an RI registered and whether there is an affectation note recorded in the registration.
Does cost price really come out cheaper?
In the initial budget, yes — there is no incorporator profit margin. In the final cost, it depends: SPE management fees, additional endorsement costs and ITBI on the transfer, risk of unforeseen capital calls. The total cost can be equal to or higher than that of a well-structured incorporation.
Can I buy SPE without risk if the administrator is trustworthy?
The administrator’s trustworthiness reduces operational risk but does not eliminate structural risks: capital calls due to market unforeseen events (material cost, legislation), illiquidity of shares, joint liability for construction liabilities. These risks exist regardless of who administers.
How do I know if I am buying SPE without asking directly?
Ask for the Incorporation Registration. If the seller cannot present the RI number at a real estate registry office, it is SPE — or worse, an irregular enterprise. Transparency about the RI is the first evaluation criterion.
Regente’s position on both models
In 27 years of real estate intermediation in Florianópolis, Regente has never marketed the SPE share purchase model or any product sold as “cost price”. Several of the enterprises we have intermediated were structured with the incorporator being an SPE — which is common and appropriate, as long as the sale is of units with registered RI and Fiduciary Fund Protection.
The reason is practical: the set of SPE risks — unpredictable capital calls, illiquidity of shares, liability for construction liabilities, alterable memorial, more costly endorsement process — creates situations where the client can be harmed by factors outside the real estate agency’s control and that often are not understood at the time of purchase.
In that same period, all launches we intermediated were conventional incorporations with verifiable delivery history. None of the builders we work with failed.
This history is not coincidence. It is the result of a selection criterion that begins with the question: is it conventional incorporation with registered RI and verifiable history?
