ValidaAuditoria
Note 01 · 24/09/2026
See what is proven and what is assumedThe developer opens the opinion, looks for his own project and finds, beside a sentence he wrote himself, the stamp "assumed." His first reading is that of a man who has just been called a liar. He has not been. The word has a technical address: NBR 14653-1:2019, the Brazilian property appraisal standard from the Associação Brasileira de Normas Técnicas (ABNT, Brazilian Association of Technical Standards), requires in item 6.9 that whenever professionals "presume and assume situations or facts" capable of affecting the result, they declare those assumptions in the report. There, assuming is a duty of transparency, not a sign of suspicion.
As Valida reads it, "assumed" describes the state of a statement: it has arrived, it has been read and it has not yet been tested against evidence. It says nothing about the character of whoever made it. And Brazilian law has worked this way for a long time. The statute presumes, the technical standard requires the assumption to be written down, the audit gives the qualification a name, the “valid, except for this” of an opinion. All of it so that the missing piece comes to light.
In daily conversation, "assuming" comes glued to guilt. The player assumes the blame, the driver assumes the crash. Seeing the word next to one's own statement seems to suggest that someone admitted something. In technical vocabulary the meaning is different: to accept as a working hypothesis. It is the "suppose that" of a math class, only with a name, a date and a document.
The seller says the watch is gold. The careful buyer writes down "gold, according to the seller" until someone runs the piece over a touchstone, the goldsmiths' classic test. The note does not call the seller a forger; it records where the information came from and what is missing to confirm it. If the metal passes the test, the note changes. The seller stays the same.
Whoever has worked for months on a project knows it is true. But knowing is not the same as having shown. The opinion does not measure conviction; it measures the evidence that reached it.
Every item in an opinion fits into one of three drawers.
| State | What it means | What the opinion records | Who decides the next step |
|---|---|---|---|
| Verified | It was tested against evidence and passed | Source, date, who examined it | No one, until there is a new fact |
| Assumed | It arrived and was read; it has not yet been tested | The statement, who made it, what is missing to verify it, estimated cost and time | Whoever hired the work: authorizes the test, accepts the risk in writing or withdraws the statement |
| Contested | The evidence contradicts the statement | The divergent fact, the source, the effect on the decision | Whoever hired the work and, where applicable, the declarant, who may bring new evidence |
Even the "contested" state, the only one that comes close to an accusation, describes a fact, not an intent. The cause may be an old version of a document or a mistyped number, and new proof changes the state once again.
Verified, for its part, does not mean guaranteed forever. The auditing standards of the Conselho Federal de Contabilidade (CFC, Federal Accounting Council), known as the NBC TA, define, in number 200, the assurance the auditor seeks as "a high level, but not absolute." Verified means "tested and approved on this date, with this evidence." If the world changes afterward, the test ages along with it.
Anyone who imagines that law deals only in certainties is surprised by the vocabulary of the Código Civil (Civil Code). Art. 1,245 says that ownership of a property is transferred by registering the title at the registry office and, in paragraph 1, that until then "the seller continues to be held as the owner of the property." Held as: the law presumes, it does not affirm. And art. 1,247 opens the exit door: "If the content of the registration does not express the truth, the interested party may demand that it be rectified or annulled." Not even the property registry is definitive truth.
Good faith follows the same logic. Under art. 1,201, whoever holds a just title "has in their favor the presumption of good faith, unless proven otherwise." Art. 422 obliges contracting parties to keep good faith from signing to performance. As Valida reads it, that is why "assumed" cannot be read as "in bad faith": the law starts from the opposite.
The Código de Processo Civil (CPC, Code of Civil Procedure) completes the design. Art. 373 gives the burden of proof to whoever alleges the fact; art. 374, IV, exempts from proof whatever has a "legal presumption" in its favor. Stating something without proof is legitimate. It just does not decide the case on its own.
Even in cases of fraud, the courts ask for proof before the label. Fraud against enforcement is selling an asset to escape a debt already being collected, like emptying the property on the eve of the bailiff's visit. Súmula 375 (Precedent 375) of the Superior Tribunal de Justiça (STJ, Brazil's superior court for federal law), issued in 2009 under the previous CPC, makes its recognition depend on the registration of the seizure (the court order holding the asset) or on "proof of bad faith by the third-party buyer." Bad faith is not presumed. It is proved.
There are cases in which the law itself turns a declaration into an official document. These are institutionalized assumptions, and what makes them acceptable is the same detail: someone answers for what was declared.
Law 7,433/1985, on property deeds, says in art. 2, §2, that, to prove that the seller is paid up with the condominium (the rule refers to art. 4, sole paragraph, of Law 4,591/1964), "a declaration made by the seller or the seller's attorney, under penalty of law, shall be considered proof of payment." The word of the seller counts as proof, and falsehood has consequences. The notary (the official who executes the deed), in turn, under art. 1, §2, records the certificates that were presented: the notary writes down what was seen.
The rural case is even sharper. The Forest Code (Código Florestal), Law 12,651/2012, created in art. 29 the Cadastro Ambiental Rural (CAR, Rural Environmental Registry), mandatory for every rural property. It works like an income tax return for the farm: the owner fills it in, and the agency checks afterward. Decree 7,830/2012, in art. 6, says that the registration "is declaratory and permanent in nature" and subjects the declarant to sanctions if the information is "totally or partially false, misleading or omitted."
And the Forest Code draws the line: the registry "shall not be considered a title for purposes of recognizing the right of ownership or possession" (art. 29, §2). The State accepts the declaration for one purpose and refuses it for another. That is what an opinion does with the assumed: it accepts it as a starting point, not as proof of what it does not prove.
NBR 14653-1, from ABNT, sets out the general procedures for appraising assets. In the second edition, of June 27, 2019, item 6.9 deals with "assumptions, qualifications and limiting conditions" and candidly admits where the gap comes from: they "are often tied to restrictions and limitations of the professional" in investigating further or obtaining clarifications.
The examples read as if taken from a negotiating table: the reliability of sources, the adoption of one area when the information diverges, the "non-examination of title conditions" (who owns it and with what burdens), of environmental liabilities and of hidden defects, the "non-verification of measurements," the "impossibility of inspection." None of them accuses anyone. All of them say what was not seen.
Item 6.2.2 covers incomplete or inconsistent documentation. The professional judges whether an appraisal is still possible and, if so, declares the qualifications, "as well as the assumptions adopted because of those conditions." The expression is in the standard. A note on transparency: the item was read in a copy hosted on a federal government page, in the archive of the Secretaria do Patrimônio da União (SPU, Federal Property Secretariat), and not in ABNT's paid catalog.
Brazilian auditing standards were written for balance sheets, not for land. They serve here as a ruler by analogy, because they solved the problem of this text: saying "I could not confirm" without saying "you were wrong." The publication read is the CFC's from 2012; the later revised versions (R1 of NBC TA 200, 500 and 580; the 2016 new wording of 705) were checked and keep the passages cited, but because item numbering varies between editions, the standards appear without item numbers.
NBC TA 705 separates two reasons for modifying an opinion. One is concluding, from the evidence, that there is a material misstatement: I found an error. The other is being unable to obtain sufficient appropriate evidence: I have no way to confirm. Only the first resembles an accusation. The second is, literally, the assumed. If the possible effects of the lack of proof are material but not pervasive (heavy, but confined to one point), a qualified opinion applies, like a warranty that covers everything "except the battery." If they are material and pervasive (they taint the whole), a disclaimer of opinion applies: the doctor who says "without the test, I give no diagnosis."
NBC TA 580 explains why the owner's word is not enough, without offending the owner: the management's written representations, "on their own, do not provide sufficient appropriate audit evidence." Sufficient and appropriate, in NBC TA 500, means good and enough: a sharp photo of another site will not do, nor will a photo of the right site that shows only one corner. And the professional skepticism of NBC TA 200, a "questioning mind," is a posture toward the evidence, not distrust of the person. From the registry office to the audit, the assumed has a place provided for it, and it comes accompanied.
| Where it appears | What is accepted without its own proof | What comes alongside | Basis |
|---|---|---|---|
| Property registry | Whoever appears is "held as owner" | Rectification or annulment | Civil Code, arts. 1,245 and 1,247 |
| Deed | Seller's declaration as proof of payment | "Under penalty of law" | Law 7,433/1985, art. 2, §2 |
| Rural Environmental Registry | What the owner declares | Sanctions if false; not a title | Decree 7,830/2012, art. 6; Law 12,651/2012, art. 29 |
| Appraisal report | What the appraiser presumed and assumed | Express declaration in the report | NBR 14653-1:2019, item 6.9 |
| Financial audit | Management's representations | Other evidence | NBC TA 580 |
As Valida reads it, a well-written assumption carries four data points: origin (who stated it, where, when), owner (who can unlock the verification, from the declarant to the registry office), deadline in business days and cost, from fees, the registry office charges, to hours of technical work. Without the four, it becomes a forgotten footnote.
The paths for closing the gap are well known. The CPC, in art. 792, §2, says that whoever buys an asset not subject to registration proves their own caution with certificates "obtained at the seller's domicile and at the place where the asset is located": two places, not one. And art. 828 leaves it to the creditor to take the initiative of annotating the enforcement action in the property registry. If the creditor does not annotate it, the lawsuit exists and the registry does not show it.
Another source sits beside the registry. Provision 149/2023 of the Conselho Nacional de Justiça (CNJ, National Council of Justice) regulates the Central Nacional de Indisponibilidade de Bens (CNIB, National Registry of Asset Unavailability), which holds orders against specific assets or against "indistinct assets," that is, against the person. Notaries and registrars are required to consult it, and the interested party's consultation on their own name is free of charge (art. 320-L).
When the fact has no paper, there is the notarial record (ata notarial): under art. 384 of the CPC, the notary may attest "the existence and the manner of existence of a fact," including with recorded image and sound. On a construction site, the percentage completed stops being assumed when someone measures it. C&S Engenharia, a group company that does management, design and execution of medium and large construction projects, describes its construction administration as "coordination of work fronts, supplies and measurements, from the site to the accounting of results." It is from the measurement that evidence is born.
An illustrative situation, built to explain the mechanism. A hypothetical developer presents a plot for a building and states three things: the plot is free of lawsuits; the project was approved by the city; the previous owner sold in 2012, everything in order.
Law 4,591/1964, in art. 32, already lists what the developer gathers before selling off the plan: title to the land, negative certificates for taxes, protest, lawsuits and real burdens (a mortgage, for example), the history of titles for the last 20 years, approved project, calculation of areas, appraisal of the cost of the work. The opinion does not invent a requirement; it checks. The property record (matrícula) is the property's file at the registry office; an annotation (averbação), the note added to it later, like a new stamp in a work card.
| Statement | State | Evidence tested | What is missing to become verified | Who authorizes |
|---|---|---|---|---|
| "The plot is free of lawsuits" | Assumed | Updated property record, no annotation of a lawsuit | Lawsuit certificates for the seller and for the location of the asset; CNIB query | Whoever hired the work |
| "The project was approved by the city" | Verified | Permit checked at the issuing agency, independent source | Nothing, until there is a new fact | Not applicable |
| "The previous owner sold in 2012, everything in order" | Assumed, with an access qualification | Current property record | Certificate from the previous registry, to complete the 20 years | Whoever hired the work, with the registry office's support |
Law 13,097/2015, art. 54, §1, protects the good-faith buyer against what does not appear in the record, with qualifications that it enumerates itself. Its §2 adds that the law does not require court certificates for the buyer's good faith; the ones in the example serve the decision of whoever hired the work, not a legal obligation. The first line carries weight but does not close the matter: certificates separate "does not appear" from "does not exist." For the third, Law 6,015/1973 (Public Records Law) applies: under art. 176, "each property shall have its own record" and, when it comes from an old transcription (the registration that preceded the matrícula system), that is where the oldest history lives.
The tally comes to this: three statements, one verified, two assumed, none contested. The pending items carry a deadline in business days and a cost in registry fees. No one was called a liar; the developer receives a work list, and the opinion remains signable.
A good share of the friction is born in the wording. The first line of the example admits three versions.
As Valida reads it, only the third will do: it turns the discomfort into a task. Whoever decides then has three honest answers: authorize the test, accept the risk in writing or withdraw the statement. The fourth, tempting, is to swap "assumed" for "verified" without new evidence, exactly what NBR 14653-1 and NBC TA 705 ask not to be done.
The limit on the other side: the assumed is no excuse. Pending items piling up with no plan to become verified turn the opinion into a legal disclaimer. When their possible effects are material and pervasive, NBC TA 705 requires abstaining from an opinion, in writing.
No. It means the statement has not yet been tested against evidence. The law starts from good faith: the Civil Code presumes the good faith of a possessor with just title (art. 1,201) and requires it of those who contract (art. 422). If the evidence contradicted the statement, the state would be "contested," and even then the opinion would describe the divergent fact, never the intent.
It is necessary and insufficient. NBC TA 580 says that management's written representations, "on their own, do not provide sufficient appropriate audit evidence." In the rural registry, Decree 7,830/2012 treats the registration as declaratory and makes the declarant responsible for whatever is false. In both cases, the declaration opens the check; it neither closes it nor makes it suspect.
No. It means tested and approved on a date, with identified evidence. NBC TA 200 defines the assurance the auditor seeks as "a high level, but not absolute." If a new fact surfaces later, such as a seizure annotated the following week, the item is examined again. That is why every verified item carries the source and the date of the check.
It is worth a map: it says where the risk is and what it costs to close it, item by item. There is a limit, though. When the points without proof have material and pervasive possible effects, NBC TA 705 requires abstaining from an opinion. The honest opinion says so plainly, instead of hiding the gap behind a comfortable conclusion.
With new evidence, preferably from an independent source, documented and dated, as NBC TA 500 guides. When the fact can only be attested by whoever sees it, the notarial record under art. 384 of the CPC gives it a date and public faith. The change is recorded in the opinion, with date, evidence and who examined it. Nothing changes state through inertia.
On receiving the opinion, the first decision fits on one line per assumption: test, accept in writing or withdraw. The stamp describes the statement. The decision belongs to whoever read it.
