Document Verification 101: LOIs, NDAs, and POFs

October 22, 2025
10 min read

In high-value transactions, documents form the foundation of trust and legal protection. Letters of Intent, Non-Disclosure Agreements, and Proof of Funds are frequently forged or manipulated by fraudsters. Understanding how to properly verify these documents can prevent catastrophic losses.

The Document Fraud Landscape

Document forgery has become increasingly sophisticated with modern technology. High-quality scanners, digital editing software, and readily available corporate templates make it possible to create convincing forgeries that can fool cursory inspection.

Common Document Fraud Statistics

  • Over 40% of fraudulent transactions involve forged documentation
  • Average loss from document fraud in luxury transactions exceeds $2.3 million
  • Most document fraud is discovered only after funds have been transferred
  • Less than 15% of fraudulent documents are detected before closing
  • Digital forgeries now outnumber physical forgeries 3:1

Letter of Intent (LOI) Verification

A Letter of Intent outlines the preliminary terms of a transaction. In luxury deals, LOIs often precede deposits or exclusivity agreements. Fraudulent LOIs create false confidence that a buyer or seller is legitimate and financially capable.

What Makes a Legitimate LOI

Essential LOI Components

  • Complete party identification: Full legal names, addresses, and entity details for all parties. Corporate entities should include state of incorporation and registration numbers.
  • Specific asset description: Detailed description of what's being bought or sold, including unique identifiers, serial numbers, or legal descriptions.
  • Clear price and terms: Exact purchase price, payment structure, deposit amount, and timeline. Vague terms like "market price" or "to be determined" are red flags.
  • Contingencies and conditions: Due diligence periods, inspection rights, financing contingencies, and conditions for closing.
  • Expiration date: LOIs should have clear expiration dates. Open-ended LOIs are unusual in legitimate transactions.
  • Proper signatures: Original signatures with dates. Digital signatures should include verification certificates.

Common LOI Forgery Techniques

Red Flags to Watch For

  • Template inconsistencies: LOIs that look computer-generated but claim to be from law firms often have formatting inconsistencies with legitimate firm documents.
  • Generic language: Overly generic terms without specific transaction details suggest the LOI is being used for multiple scams.
  • Signature irregularities: Digital signatures without proper certificates, signatures that don't match known samples, or photocopied signature pages attached to different documents.
  • Contact information mismatches: Email addresses, phone numbers, or addresses that don't match corporate records or professional directories.
  • Legal entity discrepancies: Company names that don't appear in state registries or international corporate databases.

LOI Verification Process

Step-by-Step Verification

  1. 1. Verify all parties exist: Search corporate registries for businesses. For individuals, verify identity through background checks and government databases.
  2. 2. Confirm signatory authority: Verify that the person signing has authority to bind the entity. Request corporate resolutions or power of attorney if signing on behalf of a company.
  3. 3. Validate contact information: Independently look up company contact details. Call the company's main number to confirm the person exists and has the stated role.
  4. 4. Check law firm credentials: If an attorney prepared the LOI, verify their bar membership and firm association through state bar websites.
  5. 5. Examine document metadata: PDF metadata can reveal when the document was created, who created it, and what software was used. Inconsistencies are warning signs.
  6. 6. Cross-reference with public information: If the LOI references specific assets, verify ownership through registries, title searches, or public records.

NDA and NCNDA Verification

Non-Disclosure Agreements (NDAs) and Non-Circumvention/Non-Disclosure Agreements (NCNDAs) are frequently used in luxury transactions. Fraudsters use fake NDAs to appear professional and to extract information they can exploit.

Standard NDA Components

What Legitimate NDAs Include

  • Definition of confidential information: Clear scope of what information is protected. Overly broad definitions or vague language suggests inexperience or fraud.
  • Permitted disclosures: Specific exceptions for legally required disclosures, disclosures to advisors, or information already public.
  • Duration of confidentiality: Specific time period for confidentiality obligations. Indefinite confidentiality is unusual except for trade secrets.
  • Return of materials: Requirements for returning or destroying confidential materials at transaction end or request.
  • Governing law and jurisdiction: Specific state or country law that governs the agreement and where disputes will be resolved.
  • Remedies for breach: Injunctive relief provisions and damage calculations for confidentiality breaches.

NCNDA Red Flags

NCNDAs are particularly common in international commodity trading and can be indicators of fraud when used inappropriately. Legitimate businesses in most industries don't require NCNDAs for standard transactions.

Warning Signs in NCNDAs

  • Requested too early: Demanding NCNDA before basic information exchange or preliminary discussions is unusual.
  • Overly punitive terms: Extreme penalties for circumvention or disclosure that seem designed to intimidate rather than protect.
  • Vague circumvention clause: If you can't clearly understand what constitutes circumvention, the agreement may be unenforceable or designed to confuse.
  • Strange parties listed: Long lists of intermediaries or parties with unclear roles suggests a chain of brokers with no actual principals.
  • Multiple conflicting versions: If you receive several versions with material changes, especially after signing, this indicates disorganization or fraud.

NDA/NCNDA Verification Steps

Verify all signing parties: Every party listed should be verified through corporate registries. Check that individuals have authority to sign on behalf of their organizations.

Review with legal counsel: Have an attorney review before signing. Cost is minimal compared to risk exposure from signing fraudulent documents.

Check for notarization requirements: Some jurisdictions require notarization for certain agreements. Verify notary credentials if document is notarized.

Validate corporate seals: If a corporate seal is affixed, verify it matches the company's registered seal through corporate registry documents.

Research the drafter: If an attorney or firm drafted the NDA, verify their credentials and that they represent the party they claim to represent.

Proof of Funds (POF) Verification

Proof of Funds documents are among the most frequently forged documents in luxury transactions. Fake POFs allow fraudsters to appear as legitimate buyers, gain access to confidential information, and maintain scams until they're ready to disappear.

Legitimate POF Requirements

What a Real POF Contains

  • Bank letterhead: Original bank letterhead with complete bank contact information, logos, and security features.
  • Authorized signatory: Letter signed by a bank officer with their title, direct contact information, and typically their banking license information.
  • Account holder identification: Full legal name of account holder matching the party in the transaction.
  • Specific funds statement: Clear statement that funds are available, often with a reference number or date. Generic statements about "sufficient funds" are suspicious.
  • Date restrictions: POF letters are typically valid for 30-90 days. Verify the date is current.
  • Purpose statement: Many banks include a statement about the intended use of funds, particularly for international transactions.

Common POF Forgery Indicators

Red Flags in POF Documents

  • Generic bank templates: POFs that look like they were created from online templates rather than bank systems.
  • No direct contact information: Missing phone numbers or email addresses for the signing bank officer.
  • Offshore banks exclusively: While legitimate international transactions occur, exclusive use of obscure offshore banks raises questions.
  • Photocopies only: Reluctance to provide original POF letters is suspicious. Banks can issue original letters on demand.
  • Excessive funds claims: POF showing funds far exceeding transaction requirements may indicate the same fake POF is being used for multiple scams.
  • No transaction reference: Legitimate POFs often reference the specific transaction. Generic letters raise concerns.
  • Spelling or grammatical errors: Major banks have quality controls that prevent obvious errors in official correspondence.

Direct Bank Verification Process

The only reliable way to verify a POF is direct contact with the issuing bank. This requires careful procedure to avoid contacting accomplices.

Bank Verification Procedure

  1. 1. Independent contact information: Look up the bank's contact information independently through their official website or financial directories. Never use phone numbers or emails from the POF itself.
  2. 2. Call the main bank number: Ask to be transferred to the department that issues POF letters or the specific officer who signed the letter.
  3. 3. Verify with reference number: Provide the reference number or date from the POF and ask the bank to confirm its authenticity.
  4. 4. Confirm account holder: Ask the bank to confirm that the named individual or entity holds an account. Banks may not disclose balance details but can typically confirm letter authenticity.
  5. 5. Document the call: Note the date, time, person spoken to, and their confirmation. Request written confirmation if possible.
  6. 6. Alternative verification: For international banks, consider hiring local attorneys or banking verification services to conduct in-person verification.

Counterparty Verification

Beyond document verification, the parties themselves must be verified. A sophisticated forger might create perfect documents while concealing that they have no authority to act or don't represent legitimate entities.

Corporate Registry Searches

Essential Corporate Verifications

United States:

  • Search Secretary of State databases in the state of incorporation
  • Verify active status, good standing, and registered agent
  • Confirm officers and directors match who you're dealing with
  • Check formation date against claimed company history

United Kingdom:

  • Companies House searches for company number and status
  • Verify directors and persons with significant control
  • Review filed accounts and confirmation statements
  • Check for insolvency proceedings or strike-off notices

International:

  • Each country has different corporate registry systems
  • Some require local legal assistance for searches
  • Offshore jurisdictions often have limited public information
  • Consider using international corporate search services

Beneficial Ownership Identification

Corporate structures can obscure true ownership. Shell companies, trusts, and nominee directors can hide the actual parties to a transaction. Understanding beneficial ownership is critical for assessing risk.

What is beneficial ownership: The natural persons who ultimately own or control a legal entity, typically defined as owning 25% or more or having control through other means.

Why it matters: Fraudsters use complex structures to hide their involvement. Understanding who ultimately benefits from the transaction reveals hidden risks.

How to identify: Corporate registries in many jurisdictions now require beneficial ownership disclosure. For jurisdictions without transparency, professional due diligence services can trace ownership through corporate documents and filings.

Red flags: Offshore structures with nominee directors, frequently changing ownership, or resistance to disclosing beneficial owners all warrant additional scrutiny.

Document Verification Workflow

Complete Verification Process

Phase 1: Initial Document Review (Day 1)
  • Review all documents for completeness and internal consistency
  • Check for obvious red flags (formatting, signatures, dates)
  • Extract all party names, entities, and contact information
  • Note any unusual terms or suspicious elements
Phase 2: Party Verification (Days 1-3)
  • Search corporate registries for all business entities
  • Verify individuals through background checks and public records
  • Confirm signatory authority through corporate documents
  • Check for litigation history and regulatory issues
Phase 3: Document Authentication (Days 2-5)
  • Verify POF through direct bank contact
  • Validate attorney credentials and firm associations
  • Authenticate notarizations with notary public databases
  • Examine digital signatures and certificates
Phase 4: Professional Review (Days 3-7)
  • Attorney review of all legal documents
  • Accountant review of financial documents
  • Industry specialist review of transaction terms
  • Compilation of findings and risk assessment

Cost vs. Risk Analysis

Investment in Verification

Basic document review (in-house):$0 - $500
Corporate registry searches:$200 - $1,000
Background checks:$500 - $2,500
Bank verification services:$500 - $1,500
Attorney document review:$2,000 - $5,000
Comprehensive due diligence:$5,000 - $15,000
Total comprehensive verification:$8,200 - $25,500

Compare these costs to typical transaction values and fraud losses. For a $5 million transaction, comprehensive verification represents 0.16% to 0.51% of the deal value. The average document fraud loss exceeds $2.3 million—making verification an exceptional return on investment.

Key Takeaways

  • Never rely solely on provided documents. Independent verification is mandatory for all critical documents. Even professional-looking documents can be sophisticated forgeries.
  • Verify parties before documents. A perfect LOI from a non-existent company is worthless. Always verify entity existence and signatory authority first.
  • Direct contact is essential. For POFs, bank contact is the only reliable verification. For other documents, directly contacting the issuing party through independently verified contact information is critical.
  • Engage professionals. Attorneys, accountants, and verification specialists bring expertise you likely don't have. Their fees are minimal insurance against fraud.
  • Document everything. Keep records of all verification steps, phone calls, searches, and findings. This creates an audit trail and demonstrates due diligence if disputes arise.

Document verification is not optional in high-value transactions. The sophistication of modern forgery means that visual inspection is insufficient. Every document must be independently authenticated, every party must be verified, and every claim must be substantiated. The cost of verification is trivial compared to the protection it provides.
