A single contract may be commercial in relation to one party and civil or consumer-related in relation to the other. This idea may initially appear unusual, yet it is one of the most common situations in the marketplace. When a company sells a product to an individual customer, the transaction, from the company’s perspective, generally falls within its commercial activity. From the customer’s perspective, however, it may constitute a civil or consumer transaction. This is what commercial legal doctrine refers to as mixed acts.

Mixed acts are transactions that carry two legal characterizations at the same time: they are commercial for one party and civil or non-commercial for the other. This is because the characterization of an act is not necessarily determined uniformly for all parties. Rather, it may vary according to each party’s legal status, the purpose of the transaction, and its relationship to commercial activity. A company that sells goods in the ordinary course of its business performs a commercial act, whereas a customer who purchases the goods for personal use does not perform the same commercial act from their side.

The simplest example is a consumer purchasing a product from a retail store. The store sells the product as part of its organized business activity and may have suppliers, inventory, invoices, a pricing policy, a commercial registration, and possibly an online store. The consumer, by contrast, purchases the product for personal use, not for resale or incorporation into a commercial activity. The same contract therefore has two aspects: a commercial aspect for the store and a civil or consumer aspect for the customer.

Mixed acts also arise when companies deal with individuals who do not engage in commerce. For example, if a food company purchases crops from a farmer who does not conduct trade professionally, the purchase may be commercial for the company if it is intended for resale or manufacturing, while the transaction may remain closer to a civil act for the farmer, depending on the farmer’s status and the nature of the activity. Similarly, a company may purchase a vehicle from an individual or lease real property from an individual owner who does not conduct a commercial leasing business. The relationship may have a commercial character for the company if it is connected to its business activity, while remaining civil for the other party.

The significance of mixed acts is not confined to their definition. It also lies in their practical effects on contracts and disputes. Where a contract is commercial for one party and civil for the other, each party may rely on a different understanding of the relationship. The company may view the contract as part of its commercial operations and approach it according to the logic of speed, credit, and operational efficiency. The other party may view it as an individual transaction or a consumer or civil relationship. This difference may affect contract drafting, the determination of obligations, the management of expectations, and the handling of disputes following a breach.

One of the most sensitive practical issues arising from mixed acts is judicial jurisdiction. Not every dispute involving a company automatically becomes a commercial dispute. Jurisdiction depends on the nature of the dispute, the status of the parties, the basis of the obligation, and the specific statutory provision governing jurisdiction. The Saudi Commercial Courts Law grants commercial courts jurisdiction over disputes arising between traders because of their original or ancillary commercial acts, as well as certain claims brought against traders in disputes involving commercial contracts, subject to the applicable statutory requirements. A company should therefore not assume commercial court jurisdiction merely because it is a company. Instead, it must examine the entire nature of the legal relationship.

Mixed acts are also important in matters of evidence. Commercial dealings between traders may permit forms of evidence suited to the speed and repetitive nature of commerce, including invoices, correspondence, purchase orders, account statements, and the parties’ course of conduct. A civil party or consumer, however, may not possess the same degree of organization or documentation. Companies involved in mixed transactions therefore need clearer documentation, terms written in understandable language, and publicly available policies governing sales, returns, and warranties, because the relationship does not always involve two parties with an equal level of professional experience.

This concept is particularly important in electronic commerce. An online store conducts an organized commercial activity, whereas many of its customers purchase products for personal purposes. Commercial rules therefore intersect with consumer protection, disclosure, data protection, and electronic transaction policies. It is not sufficient for an online store to publish lengthy and complicated general terms. It must clearly disclose essential information, the product price, payment methods, exchange and return policies, and communication channels, because the relationship is commercial for the store but may be consumer-related for the customer.

A common mistake among companies is to draft their contracts and terms as though the other party were always a professional trader. This may be appropriate for business-to-business supply agreements, but it is not necessarily suitable for sales to individuals or dealings with consumers, individual property owners, or independent contractors. Mixed acts require clearer language, greater disclosure, and a better balance in defining obligations, because one party may not be a trader and may not possess the same commercial expertise.

Conversely, the mixed nature of a relationship does not mean that the non-trader has no obligations. If that party accepts a clear contract, receives goods, benefits from a service, or breaches a specific obligation, legal consequences may arise under the applicable rules. The essential point, however, is that the company must structure the relationship on a legally sound basis rather than relying on assumptions derived from transactions conducted solely between traders.

Understanding mixed acts also assists companies in designing different policies for different types of customers. Selling to a wholesaler requires credit, delivery, and warranty terms that differ from those applicable to a final consumer. Dealing with a distributor differs from dealing with an individual customer. Contracting with a shipping company differs from contracting with an independent service provider performing a limited task. The more accurately a company distinguishes between the nature and status of the parties, the better it can design precise contracts and policies that are less susceptible to disputes.

The value of mixed acts is also evident in risk management. In a commercial relationship between two companies, it may be reasonable to assume a higher degree of experience, negotiation, and documentation. In a mixed relationship, however, the company may be required to provide clearer terms and reduce ambiguity, particularly where the other party is a consumer or an individual who does not engage in commerce. Ambiguity does not harm the customer alone; it also harms the company by creating opportunities for complaints, disputes, and misunderstandings.

In conclusion, mixed acts are transactions that are commercial for one party and civil or consumer-related for the other. They are common in companies’ daily dealings, particularly in sales to individuals, electronic commerce, and certain purchases from non-traders. Understanding this concept enables a company to select appropriate contractual terms, determine the competent judicial authority, establish a clear evidentiary policy, and deal with each party according to their actual legal position rather than merely according to the form of the contract.
