Sale of Goods
From the Business Law curriculum
TL;DR
The Sale of Goods Act (SOGA) governs contracts where ownership of goods transfers for a price, implying key terms even if not explicitly stated. These implied terms protect both buyers and sellers, covering aspects like title, description, quality, and fitness for purpose. Understanding SOGA is crucial for consumer and commercial transactions to ensure legal compliance and protect your rights.
1. The Mental Model
Think of the Sale of Goods Act as a default checklist for buying and selling stuff. Even if you don't write everything down, the law assumes certain things are part of your deal, like the seller actually owns what they're selling.
2. The Core Material
The Sale of Goods Act (SOGA), primarily the Sale of Goods Act 1979 in the UK, lays down the legal framework for contracts involving the sale of goods. This means when goods are transferred from a seller to a buyer for a money consideration (the price).
Key Definitions
- Goods: Tangible personal property (items you can touch and move), excluding land, money, and intangible things like shares or intellectual property.
- Seller: The person who transfers or agrees to transfer the property in goods to the buyer.
- Buyer: The person who buys or agrees to buy goods.
- Price: The money consideration for the sale of goods.
Core Principle: Implied Terms

SOGA's most significant contribution is the inclusion of "implied terms." These are conditions and warranties that are automatically part of a sale of goods contract, unless explicitly excluded (and even then, exclusions are often limited, especially in consumer sales).
Conditions vs. Warranties
- Conditions: These are fundamental terms. If a condition is breached, the buyer can repudiate the contract (end it, get their money back, and refuse the goods) and claim damages.
- Warranties: These are less central to the contract. If a warranty is breached, the buyer can only claim damages, not end the contract.
Important Implied Terms (Sections 12-15 SOGA 1979)
-
Implied Term as to Title (Section 12):
- Condition: The seller has the right to sell the goods.
- Warranty: The goods are free from any charge or encumbrance not disclosed or known to the buyer before the contract, and the buyer will enjoy quiet possession of the goods.
- Why it matters: You don't want to buy stolen goods or goods subject to a finance agreement you didn't know about.
-
Implied Term as to Description (Section 13):
- Condition: When goods are sold by description, the goods must correspond with that description.
- Why it matters: If you order a "red leather sofa," you should get a red leather sofa, not a blue fabric one.
-
Implied Term as to Quality or Fitness (Section 14):
- This section applies when the seller sells goods in the course of a business.
- Condition (Satisfactory Quality): The goods supplied under the contract are of satisfactory quality. This considers fitness for all common purposes, appearance and finish, freedom from minor defects, safety, and durability.
- Condition (Fitness for Particular Purpose): If the buyer makes known to the seller any particular purpose for which the goods are being bought, there's an implied condition that the goods are reasonably fit for that purpose, unless it's unreasonable for the buyer to rely on the seller's skill or judgment.
- Why it matters: Goods shouldn't fall apart immediately, and if you tell the shop you need a waterproof jacket for mountaineering, it should actually be waterproof enough for that.
-
Implied Term as to Sample (Section 15):
- Condition: If goods are sold by sample, the bulk must correspond with the sample in quality, the buyer must have a reasonable opportunity to compare the bulk with the sample, and the goods must be free from any defect making their quality unsatisfactory, which would not be apparent on reasonable examination of the sample.
- Why it matters: What you see in the showroom sample should be what you get when your order arrives.
Passing of Property and Risk

- Passing of Property: This means when ownership of the goods transfers from the seller to the buyer. Generally, risk passes with property.
- Passing of Risk: This determines who bears the loss if the goods are damaged or destroyed.
- General Rule (Section 20): Unless otherwise agreed, the goods remain at the seller's risk until the property in them is transferred to the buyer. Once property is transferred, the goods are at the buyer's risk whether delivery has been made or not.
- Specific Goods (Section 18, Rule 1): Where there's an unconditional contract for the sale of specific goods in a deliverable state, property passes when the contract is made, regardless of payment or delivery.
- Unascertained Goods: Property cannot pass until the goods are ascertained (identified and separated).

Remedies for Breach

- Buyer's Remedies: Reject goods (for breach of condition), claim damages, specific performance (court orders seller to deliver goods).
- Seller's Remedies: Action for the price, claim damages for non-acceptance, lien on goods (right to retain goods until payment), right of stoppage in transit.
3. Worked Example
Imagine you visit "TechGadget Store" and tell the salesperson you need a laptop specifically for high-end video editing, mentioning the software you use. The salesperson recommends a particular model, assuring you it's "perfect for professional video work." You buy it.
A week later, the laptop constantly crashes when you try to use your video editing software. It turns out the graphics card is underpowered for the task, and the fan is making a terrible grinding noise, clearly not "satisfactory quality" for a new machine.
- Breach of Condition (Fitness for Particular Purpose): You explicitly made known your specific purpose (high-end video editing), and you relied on the seller's skill and judgment. The laptop is not reasonably fit for that purpose.
- Breach of Condition (Satisfactory Quality): The grinding fan and constant crashing indicate it's not of satisfactory quality in terms of performance and freedom from defects.
Because these are breaches of conditions, you would likely be entitled to reject the laptop, return it, and get a full refund, in addition to claiming any damages incurred (e.g., lost work time). If it were just a minor cosmetic scratch (a breach of warranty), you might only be able to claim a discount or repair, not return the whole laptop.
4. Key Takeaways
- SOGA automatically implies terms into contracts for the sale of goods, protecting both parties.
- The core implied terms relate to title, description, satisfactory quality, fitness for purpose, and sale by sample.
- Breach of a "condition" allows you to end the contract and get a refund/damages; breach of a "warranty" only allows damages.
- The concept of "passing of property" determines when ownership transfers, which usually coincides with the "passing of risk."
- SOGA applies to business-to-business and business-to-consumer sales, though consumer rights are further enhanced by other legislation (like the Consumer Rights Act 2015 in the UK).
Common Mistakes to Avoid:
- Assuming all terms are written down: SOGA adds terms even if you don't explicitly discuss them.
- Confusing "condition" with "warranty": Understanding this difference is crucial for knowing your rights if a problem arises.
- Not identifying if the seller is acting "in the course of a business": Section 14 (satisfactory quality/fitness) only applies here.
- Ignoring the concept of "passing of risk": Knowing when risk transfers can be critical if goods are lost or damaged before delivery.
5. Now Try It
Think of a recent purchase you made (e.g., a new smartphone, a used car, a piece of furniture). Spend 15 minutes considering:
1. Which implied terms from SOGA (title, description, satisfactory quality, fitness for purpose, sample) were relevant to your purchase?
2. If something went wrong with that item, which implied term would likely have been breached? Would it be a condition or a warranty, and what remedies would you expect?
Success looks like you being able to identify at least two relevant implied terms for your purchase and clearly explaining whether a hypothetical problem would breach a condition or a warranty, outlining the resulting remedy.
