Risks of Buying an Unregistered Property in Florianópolis

The risks of buying an unregistered property in Florianópolis affect thousands of buyers every year. With 40% of the city’s properties in irregular status, the supply of land and homes traded only by possession remains high. The price attracts. The documentation concerns are less frightening than they should be.

The problem emerges later: when financing, selling, inventorying, or simply sleeping soundly. An unregistered property carries legal vulnerabilities that the uninformed buyer discovers only after investing time and money.

• Neighborhoods like Rio Vermelho (81.84% irregular) and Campeche (71.80%) lead this scenario
• Devaluation reaches 40% compared to registered properties

Below, the seven most serious risks and a due diligence checklist to protect your assets.

What are the risks of buying an unregistered property in Florianópolis?

The risks of an unregistered property in Florianópolis stem from a simple fact: possession does not equal ownership. Understanding the difference between property registration record, deed, and possession is the first step. The Brazilian Civil Code reserves ownership only to those who register the title in the property registration record.

Whoever buys by possession acquires personal rights against the seller, but not real rights enforceable against third parties. This means that anyone with a registered title can claim the property, even if you have occupied the site for years.

Florianópolis aggravates this equation by concentrating more than 70,000 irregular lots (source: redeplanejamento.pmf.sc.gov.br). The volume of informal transactions feeds a market where informality becomes normalized, and risks remain invisible until the moment of crisis.

• Buyers lose properties in judicial disputes
• Investors discover liens on assets they believed were free
• Families face blocks in inventory due to lack of registration record

The 7 Risks Every Buyer of an Unregistered Property Must Know

1. Loss of Property to the True Owner

The most serious risk. If the property has a registration record in someone else’s name, the registered owner can claim possession at any time. Neither years of occupation nor property tax payment guarantee automatic protection.

The buyer will need to prove quiet and undisturbed possession for at least 5, 10, or 15 years (depending on the type of adverse possession (usucapião)) to attempt to obtain ownership. Meanwhile, they live under constant legal insecurity.

2. Duplicate Sale of the Same Property

Without an individualized registration record, nothing prevents the possessor from ceding possession rights to more than one person. The risks of informal deed contracts accumulate in this scenario. The notary office registers the possession deed according to the transferor’s statement. There is no automatic mechanism that cross-references prior assignments.

• Two or more buyers can dispute the same lot
• The solution requires a lengthy and costly court process

3. Inability to Obtain Bank Financing

Banks require updated registration record and free of liens to grant real estate financing. An unregistered property does not meet this requirement.

The practical impact:

• You cannot finance the purchase
• The future buyer of your property also cannot
• The property loses liquidity in the market

In practice, the property loses liquidity. Buyers seeking security may prefer to purchase off-plan properties in Florianópolis or require complete real estate financing documentation.

4. Appearance of Heirs with Rights to the Property

When the original possessor dies, their heirs can claim the property. Even if you bought in good faith and paid the full amount, the heirs possess succession rights over the deceased’s assets.

• Surviving spouse can question the assignment
• Minor children possess strengthened legal protection
• Assignment made without consent of all heirs is voidable

5. Devaluation of Up to 40% of Assets

Properties without regular documentation are worth significantly less than registered properties in the same region. Devaluation reaches 40%, according to Florianópolis real estate market surveys.

On the other side, properties that undergo regularization register appreciation of up to 50%. This differential is the “premium of legal security” that the market charges.

• A lot worth R$ 500,000 with a registration record may be worth only R$ 300,000 on the same street without documentation

6. Blocking in Inventory and Division

If you die with an unregistered property, your heirs face severe difficulties in inventory. The property registration office does not recognize the asset as part of your formal estate.

The inventory process will require:

• Judicial or extrajudicial recognition of possession
• Possible adverse possession (usucapião) action before division
• Additional costs with lawyers and appraisers

The inventory timeline can double or triple due to the documentary irregularity.

7. Document Fraud in Informal Transactions

Informality creates space for sophisticated fraud. Possession documents can be forged easily. Without consulting the registration record, the buyer does not verify the chain of title.

Common scams in Florianópolis include:

• Assignment of rights over public area not subject to regularization
• Presentation of false powers of attorney in the possessor’s name
• Sale of areas in APP (Permanent Preservation Area) where construction is prohibited
• Documentation that omits existing liens or legal disputes

How to Protect Your Investment with Real Estate Due Diligence

Real estate due diligence verifies the legal, tax, and environmental status of the property before purchase. The objective is to identify hidden risks and avoid damages that cost much more than the analysis itself.

Prior real estate due diligence consulting rarely exceeds 1 to 2% of the property’s value. Skipping this step can mean losing the entire property.

Documents to Verify Before Purchase

• Updated property registration certificate (maximum 30 days) from the Property Registry Office
• Negative lien certificate on the property
• Certificate of real and personal actions
• Property tax (IPTUIPTUVer tudo →) current and compatible with the built area
• Occupancy permit or construction license (if there is a building)
• Negative certificates of seller’s debts (federal, state, municipal, labor)

Mandatory Queries at Public Agencies

• Municipal Government: verify zoning, urban restrictions, and regularization feasibility
• IPUF/SMDU: confirm whether the property is in a preservation area or coastal strip
• Property Registry Office: check for existence of registration record and chain of title
• Federal Court: properties on coastal lands require consultation with SPU (federal patrimony service)

Due Diligence Checklist Before Buying an Unregistered Property

Before signing any document, work through this list:

• Request the property registration certificate — if it does not exist, understand why and assess the risk
• Verify the chain of possessions — ask for all prior contracts and assignments
• Confirm the seller’s identity — compare with official documents
• Consult the municipal zoning — the property may be in a non-regularizable area
• Research legal actions against the seller and against the property
• Verify if the property respects the limits of APP and coastal strip
• Require ART or RRT from a qualified professional if there is construction
• Consult a lawyer specialized in land title regularization before closing the deal

No discount in price compensates for the risks of acquiring a property without prior verification.

Frequently Asked Questions About Unregistered Property Risks

I’ve paid property tax for 20 years — does that prove I’m the owner?

Paying property tax proves that the Municipal Government recognizes you as a taxpayer, not as owner. Property tax serves as a sign of possession, useful in adverse possession processes, but insufficient to prove ownership.

Does an informal deed registered at a notary office guarantee security?

Registration at a notary office confers public faith on the document, but does not transfer ownership. Only registration at the Property Registry Office produces this effect.

Is it possible to regularize an unregistered property after purchase?

Yes. See the complete guide on how to regularize property in Florianópolis. The main routes include extrajudicial adverse possession (R$ 5,000 to R$ 12,000, timeframe 6 months to 1 year), REURB (free in social modality), and compulsory adjudication (R$ 3,000 to R$ 10,000). Feasibility depends on the property’s documentary and land status.

Can an unregistered property in Florianópolis participate in Floripa Regular?

It depends on location and modality. The Floripa Regular program has already regularized more than 800 properties since 2023 and serves informal urban nuclei that meet the requirements of Law 13.465/2017 (source: redeplanejamento.pmf.sc.gov.br).
