A digital signature on documents This helps to understand, by contrast, the handwritten signature: the mark made by hand by which a person expresses agreement with the content recorded on paper. The topic risks of handwritten signatures It brings together threats to the authenticity, preservation, speed, and control of the documentary process.
Recognizing these limitations allows for the definition of preventative measures, the reduction of rework, and the selection of a signature method compatible with the value, purpose, and level of exposure of each corporate business document.
Summary
- A signature on paper can be forged, altered, lost, or damaged.
- In-person collection or logistics tend to increase lead times, costs, and outstanding issues.
- Parallel versions and unregistered access hinder document governance.
- Electronic workflows can add authentication, audit trails, and centralized monitoring.
Quick facts
- According to Code of Civil ProcedureThe validity of a private document ceases when its authenticity is challenged, until its veracity is proven.
- According to Library of CongressPreserving paper requires a stable, relatively dry environment with approximately 35% humidity and minimal exposure to light.
- O FBI describes examinations of writing, watermarks and printing processes to determine the authenticity or origin of questioned documents.
What are the main risks of a handwritten signature?
The seven risks below do not make every paper document invalid or insecure. They point to weaknesses in processes that depend on physical circulation, visual verification, and manual filing. The analysis should consider the contract, the signatories, confidentiality, and the consequences of a dispute. The comparison with the Digital and handwritten signature It helps to select controls that are proportionate to the context.
1. Counterfeiting or adulteration
A company name can be imitated, and details, amounts, dates, or clauses can be replaced after signing.
In a supplier contract, for example, changing an attachment can alter prices without the approver noticing. Prevention involves initialing documents when applicable, page numbering, integrity checks, controlled copies, and secure storage.
In electronic flows, cryptographic mechanisms and event logs can make alterations detectable. NIST explains Digital signatures allow for the detection of unauthorized modifications and the authentication of the signatory's identity.
2. Loss and physical damage
Paper can disappear during transport, end up on the wrong table, or suffer from tears, moisture, fire, and deterioration.
In the case of a lost employment contract between branches, the company needs to search for, reissue, and collect signatures. Delivery protocols, copy scanning, classification, and preservation plans reduce exposure. Management of loss of documents It should also define who is responsible and what the incident response is.
On electronic platforms, centralized copies and permissions reduce dependence on a single physical original.
3. Authentication failures
The visual similarity between a signature and a known pattern does not, by itself, prove who signed it, when the signature was given, or whether informed consent was obtained.
In a high-value sale, a third party may sign without the power to represent the seller. Preventive measures include identity verification, powers of attorney, witnesses when applicable, and notarization procedures as needed. document authentication It must be adjusted to the risk.
In the electronic environment, additional factors, such as codes, biometrics, and certificates, can reinforce identification.
4. Delay in collection
Manual signing often requires printing, moving, mailing, scheduling, or returning multiple copies. A contract with multiple signatories may be delayed due to travel or delivery to the wrong address.
To prevent delays, the company should map out who is responsible, deadlines, substitutes, and follow-up channels. One document workflow A well-defined approach reduces waiting times and reveals bottlenecks.
In an electronic workflow, simultaneous or sequential sending, reminders, and real-time status updates tend to facilitate the collection of outstanding payments.
5. Printing, shipping and archiving costs
The cost of paper does not represent the entire expense. Toner, equipment, envelopes, transportation, notarization, physical space, administrative hours, and reprints also make up the cost per document.
In large-scale operations, repetitive expenses consume budget and team hours. Prevention begins with process measurement and the elimination of redundant steps. Analysis of... cost reduction You should compare the entire workflow. In electronic solutions, the cost tends to be concentrated in the platform and governance.
6. Lack of version and access control
Printed minutes, files sent by email, and signed copies can coexist without clear identification of the current version.
In a corporate negotiation, an outdated draft can require repeated approvals. It's also difficult to know who consulted or copied a document stored in a shared filing cabinet. Prevention includes standardized nomenclature, a single version for signature, access lists, and controlled disposal.
practices document management They provide consistency to the cycle. Electronic systems can record versions, permissions, views, and actions in a centralized track.
7. Legal uncertainty
Insecurity arises when a company cannot demonstrate authorship, integrity, representation, date, or chain of custody. This can amplify discussions about the validity and content actually accepted, especially when there are erasures or divergent pages. Prevention requires a risk matrix, formal requirements, legal review, and preservation of evidence.
According to Law No. 14.063 / 2020Electronic signatures are classified as simple, advanced, or qualified according to their identification, authorship, and integrity mechanisms. The appropriate type depends on the context and applicable requirements.
How to prevent risks and measure process improvement?
Prevention must combine rules, people, and technology. Before migrating documents, the company needs to inventory document types, classify impact, and define the level of authentication. According to... Provisional Measure No. 2.200-2/2001ICP-Brasil was established to guarantee the authenticity, integrity, and legal validity of electronic documents and secure transactions. The standard provides a reference for processes that require digital certificates and greater formality.
| KPI | how to calculate | What it reveals |
|---|---|---|
| Average subscription time | Total time between submission and completion divided by the number of documents completed. | Speed and bottlenecks |
| Cost per document | Direct costs and labor hours divided by the volume processed. | Financial efficiency |
| Lost item fee | Lost documents divided by documents moved. | Logistics risk |
| Rework | Recreated documents divided by the documents started. | Flow quality |
| Pendencias | Overdue documents divided by submitted documents. | Monitoring capacity |
| Fraud incidents | Confirmed or investigated occurrences by period | Exposure and effectiveness of controls |
The indicators should be compared before and after the change, using the same document sample. Reducing deadlines while incidents increase does not represent an improvement. A cheap solution can also generate indirect costs and rework.
The analysis of Digital Signature ROI It should include economics, productivity, conversion, satisfaction, and risk. The results need to be reviewed periodically by Legal, operational areas, and information security.

Reducing the risks of handwritten signatures strengthens governance.
Reducing risks doesn't require immediately abandoning all physical documents, but rather establishing clear criteria for each process. Sensitive contracts, large-scale operations, and transactions with geographically dispersed signatories often demand more traceable controls.
The company must document policies, empower teams, monitor KPIs, and review exceptions. To structure a more agile, centralized, and verifiable workflow, the ZapSign's digital signature solution allows you to treat the risks of handwritten signatures with resources suitable for routine documentation.
Frequently Asked Questions (FAQ)
Yes. A handwritten signature can have legal effect, provided the document meets the requirements applicable to the transaction and there are conditions to demonstrate authorship and integrity. Validity does not depend solely on the signature format. The type of contract, the capacity of the parties, the expression of will, the legal formalities, and the quality of the available evidence also influence any eventual analysis.
No. A scanned image visually reproduces a signature, but it does not, by itself, contain cryptographic mechanisms capable of linking the signatory to the document or detecting alterations. A digital signature is created using specific technology and can incorporate certificates, keys, and integrity checks. A scanned signature may be accepted in certain contexts, but it presents different evidence and should be evaluated according to the risk involved.
The company can verify the identity and representation of the signatory, number pages, control versions, record deliveries, store originals in a protected location, and apply notarization when necessary. It is also advisable to limit access and define procedures for erasures, replacements, and copies. No single measure eliminates all risk; the combination must reflect the value of the document and the consequences of fraud.
Many contracts and business documents can be signed electronically, but some operations have specific legal, regulatory, or notary requirements. Before defining the method, it is necessary to verify the nature of the act, the identity of the parties, the required level of trust, and the industry rules. Higher-impact documents may require a qualified signature, digital certificate, or other formalities stipulated by law.
Depending on the solution and configuration, the electronic workflow can record date and time, IP address, authentications, submission events, viewing, acceptance, signing, and completion. It can also maintain the signed version, the history of actions, and integrity mechanisms. This evidence assists in audits and disputes, but it needs to be preserved, accessible, and consistent with the purpose of the document and applicable legislation.
