The Hidden Risk of Informal Contracts in Nigeria’s Business Ecosystem
Trust is the currency of Nigerian business.
Handshakes seal deals. Verbal agreements drive commerce. Relationships matter more than paperwork. This is our business culture.
But here is the problem. When things go wrong, that handshake will not help you in court. Those verbal promises become your word against theirs.
Informal contracts are convenient. They are fast. They are culturally comfortable. But they carry hidden risks that can destroy your business.
Let me explain why informal contracts are dangerous and how to protect yourself.
Understanding informal contracts in the Nigerian context
According to USLegal, an informal contract is defined as “a contract other than one under seal, a recognizance, or a negotiable instrument. An informal contract derives its force not from the observance of formalities but from the mutual agreement between parties.”
USLegal, Inc. Informal Contract Law and Legal Definition. https://definitions.uslegal.com/i/informal-contract/
In Nigeria, oral contracts are legally recognized and can create binding obligations. However, proving their existence and terms presents significant challenges.
These contracts can take various forms. Verbal agreements during business meetings or phone conversations. Handshake deals common in traditional Nigerian business culture. Email exchanges outlining terms without formal documentation. Text message confirmations of business arrangements. Implied agreements arising from the conduct of parties.
The legal validity of informal contracts under Nigerian law
Are informal contracts legally binding in Nigeria?
Under Nigerian law, an unwritten contract is enforceable provided it complies with all the requirements of a valid contract. These include offer, acceptance, consideration, intention to create legal relations, and legal capacity of the parties.

The essential elements for enforceability are clear. Offer and acceptance requires a clear offer by one party and unequivocal acceptance by the other. Consideration requires something of value exchanged between the parties. There must be intention to create legal relations. All parties must have legal capacity to contract, typically age 18 and above. The contract must not be for an illegal purpose.
As the court held in *NURTW & Ors v. First Continental Insurance Co. Ltd (2019) LPELR-48005(CA)*, a contract requires all these basic elements to be present for a binding and enforceable agreement to arise.
Important exceptions: contracts that must be in writing.
Despite the general validity of oral contracts, Nigerian law mandates that certain contracts must be made in writing. These include contracts for the sale of land, any disposition of land, mortgage agreements or charges on land, and contracts requiring one person to answer for the debt of a third person.

The hidden risks of informal contracts
Evidentiary challenges: the burden of proof.
When parties enter into a verbal or poorly documented agreement, they face substantial challenges if disagreements arise. Without written records, proving what was agreed becomes a matter of he said, she said. Over time, parties may genuinely remember terms differently. Proving oral contracts often relies on witness testimony, which may be unavailable or unreliable. The party asserting the existence of an informal contract bears the burden of proof.
To prove an oral contract, the party asserting its existence must adduce credible evidence through various means. Written communications, including letters, email correspondence, text messages, receipts, photographs, notes, quotes, faxes, bills of quantities, and evaluations. The conduct of the parties shows that their actions or performance objectively demonstrate an intention to be bound. Reliable verbal testimony of any of the parties. Testimony of third parties who were present when the oral contract was made. Proof of execution of obligations under the contract. Collection attempts, including demand notices for payment of outstanding debt. Bounced cheques and unpaid invoices. Evidence of part payment effected.
Ambiguity and misunderstanding.
Informal contracts are particularly susceptible to ambiguity and misinterpretation. Without clear, written terms, parties may genuinely understand terms differently. Important details may be overlooked or assumed. Cultural or linguistic differences can lead to miscommunication. Without defined boundaries, expectations may expand beyond original intent.
Lack of protective clauses.
Formal written contracts typically include protective provisions that safeguard parties’ interests. Informal contracts generally lack dispute resolution mechanisms with no predetermined process for resolving disagreements. They lack termination clauses with unclear procedures for ending the relationship. They have no liability limitations or caps on potential damages. They lack confidentiality provisions for sensitive business information. They have unclear intellectual property rights ownership. They lack force majeure clauses for unforeseen circumstances.
Enforcement difficulties.
Even when informal contracts are legally valid, enforcing them through Nigeria’s court system presents substantial challenges. Nigerian courts face significant backlogs, meaning contract disputes can take years to resolve. Proving informal contracts often requires extensive witness testimony and evidence gathering. The lack of clear documentation makes judicial outcomes less predictable. Even successful judgments may be difficult to enforce.

Recent developments in 2024-2025
Informal Sector Employment (Regulation) Bill 2025.
In November 2025, the Nigerian Senate passed the Informal Sector Employment (Regulation) Bill, 2025, which seeks to formalize and regulate the employment of domestic workers, apprentices, and interns. This legislation addresses the absence of structured legal protection for informal workers.
The key objectives of the bill are to formalize the employment of domestic workers, apprentices, and interns. To protect them from sexual harassment, physical abuse, and exploitation. To ensure fair remuneration and decent working conditions. To establish a biometric database of domestic workers and employers. To prevent child labour in domestic work. To guarantee decent feeding, social security, and healthcare access for domestic staff.
Informal Sector Private Employment Agencies (Regulation) Bill 2025.
The Senate has also passed for second reading a bill that seeks to regulate informal employment and authorize the licensing of private job agencies to protect the rights of informal workers. The bill is sponsored by Senator Mohammed Sani Musa.
According to Senator Musa, the bill was designed to address “widespread labour rights violations, abuse, and the lack of regulation in the informal sector.” The bill would empower the National Directorate of Employment to issue licences to private employment agencies and ensure they operate under standardised, transparent, and fair practices.
Minimum wage amendment.
On July 29, 2024, Nigeria’s president signed into law the National Minimum Wage (Amendment) Act 2024, raising the national monthly minimum wage from ₦30,000 to ₦70,000, a 133% increase. The legislation also shortened the statutory review cycle from five years to three years. This development has particular implications for informal employment contracts, as it establishes clearer baseline expectations for compensation.
Judicial emphasis on procedural fairness.
Recent court decisions have emphasized procedural fairness in dismissals and stronger protection of employee rights even where contracts are informal. In Adefisoye Stephen Abiodun v Safari Support West Limited, the National Industrial Court held that even where an employee is still on probation, an employer must offer plausible justification for the termination. This trend suggests increasing judicial willingness to look beyond formal documentation to protect parties who have entered into informal arrangements.
Technology sourcing and procurement regulations.
The National Information Technology Development Agency has issued Guidelines for Nigerian Content Development in Information and Communication Technology that require government and public sector bodies to source locally 40% of computer hardware from NITDA-approved manufacturers. International software vendors must register their products, capabilities, and organisation on the NITDA portal. Government and public sector bodies are obligated to source locally all software and software-enabled products for which there is indigenous capacity.
Sector-specific vulnerabilities
Small and Medium Enterprises.
Nigerian SMEs are particularly vulnerable to the risks of informal contracts due to limited legal resources and expertise, a relationship-driven business culture, cash flow constraints making litigation impractical, and limited awareness of legal risks.
Supply chain and vendor relationships.
The Nigerian Labour Act requires employers to provide written particulars of employment within three months, including wages, payment manner, and notice periods. Despite this, many employment relationships in Nigeria remain largely informal. The National Industrial Court has the authority to imply terms into employment contracts where none are expressly stated.
Supply chain and vendor relationships.
Nigeria’s supply chains often operate on informal arrangements, creating vulnerabilities including quality disputes without defined standards, delivery disagreements without clear timelines, payment disputes without documented terms, and liability confusion when problems arise.
Real estate and property transactions.
While land transactions must be in writing under Nigerian law, many preliminary agreements and agency relationships in real estate remain informal, leading to disputes over commissions, terms, and obligations.
The cost of informality: real business impacts
Financial losses. The financial impact of informal contracts can be severe. Difficulty proving amounts owed for uncollected debts. Resources tied up in unresolved disputes. High costs of attempting to enforce informal agreements. Damaged reputation from disputes.
Relationship damage. Disputes arising from informal contracts often permanently damage business relationships. Trust erosion within business networks. Reputational harm in industry circles. Loss of future business opportunities. Stress and emotional toll on business owners.
Operational disruption. Informal contract disputes can severely disrupt business operations. Management time diverted to dispute resolution. Uncertainty affecting business planning. Disrupted supply chains or service delivery. Employee morale and productivity impacts.
Best practices: mitigating risks in Nigeria’s business environment
Formalize critical agreements.
While not all agreements require extensive documentation, critical business relationships should always be formalized. Partnership agreements should always be in writing with clear terms. Employment contracts need formal documentation meeting Labour Act requirements. Supplier agreements need written terms covering quality, delivery, and payment. Service contracts need clear scope, deliverables, and compensation terms.
Document all communications.
Even when formal contracts are not immediately executed, follow up verbal discussions with email confirmations. Maintain records of text messages and WhatsApp exchanges. Keep notes of meetings and phone conversations. Store copies of all correspondence systematically.
Use simple written agreements for smaller transactions.
For routine or lower-value transactions, develop template agreements that can be quickly customized. Use email confirmations outlining key terms. Implement digital signature solutions for speed. Maintain a library of standard terms and conditions.
Include essential protective clauses.
All written agreements should include clear payment terms including amounts, schedules, and methods. Dispute resolution provisions specifying arbitration or mediation clauses. Termination provisions with notice requirements and processes. Liability limits with reasonable caps on potential damages. Governing law specifying Nigerian law and jurisdiction.
Seek professional legal review.
For significant transactions, engage qualified legal counsel early in negotiations. Have agreements reviewed before execution. Ensure compliance with sector-specific regulations. Update standard agreements regularly to reflect legal changes.
Implement internal contract management systems.
Businesses should establish robust contract management practices. Centralized storage of all agreements. Regular review and renewal processes. Training for staff on contract requirements. Clear approval hierarchies for different contract values.
When informal contracts make sense
Despite the risks, informal contracts still have a place in certain circumstances.
For small, one-time transactions where the cost of formalization exceeds the transaction value, informal arrangements may be practical. Even simple written confirmations are advisable.
In established relationships with proven track records, some flexibility may be appropriate. Periodic formalization and documentation remain important.
Initial exploratory discussions may appropriately remain informal but should quickly transition to written documentation once terms solidify.
The path forward: building a culture of formalization
Individual responsibility.
Business owners and professionals must recognize the value of formal documentation. Invest time and resources in proper contract formation. Resist cultural pressure to rely solely on trust and relationships. Educate partners and counterparties on the importance of formalization.
Industry-level changes.
Trade associations and industry groups can develop standard form contracts for common transactions. Provide education and resources on contract management. Establish best practice guidelines. Create accessible dispute resolution mechanisms.
Regulatory support.
Government and regulatory bodies should continue strengthening legal protections for parties in informal arrangements. Provide accessible legal resources for SMEs. Streamline court procedures for contract disputes. Enhance enforcement mechanisms for contractual obligations.
Where to start tomorrow
Do not try to formalize every agreement at once.
Start with your highest value relationships. Key suppliers, major customers, critical employees.
Use simple templates. Do not wait for perfect legal documents. A simple written confirmation is better than nothing.
Confirm verbal agreements in writing. Send an email after every important conversation. Summarize what was agreed.
Keep records. Save emails. Store messages. Document everything.
Get help for large transactions. Pay for legal review. It is cheaper than litigation.
Final word
Informal contracts represent a significant hidden risk in Nigeria’s business ecosystem.
They offer apparent advantages in terms of speed, flexibility, and cultural compatibility. But these benefits are vastly outweighed by the potential for disputes, losses, and business disruption.
Nigeria’s regulatory landscape is evolving. New legislation is strengthening protections but also increasing compliance requirements. The National Minimum Wage Act 2024, the Informal Sector Employment Bill 2025, and the Informal Sector Private Employment Agencies Bill 2025 all point toward greater formalization.
The path forward requires a balanced approach. Recognize the cultural context that makes informal arrangements appealing. Implement practical measures to protect your business interests. Embrace documentation. Seek professional guidance. Build robust contract management practices.
In an increasingly complex and competitive business environment, the question is not whether you can afford to formalize your contracts. It is whether you can afford not to.
