You feel confident about Agency. You’ve memorized actual vs. apparent authority. Then a REG question hits you with a scenario where a principal's past actions contradict their agent's written contract. The #1 reason candidates stumble here isn’t forgetting a rule; it’s failing to see that the exam tests the principal's communication to the third party, not just their instructions to the agent. This is where points are lost.
For the CPA REG exam, a principal is liable for an agent's authorized acts (actual or apparent) and torts within the scope of employment. A surety is primarily liable for a debtor's default. Passing requires you to diagnose the type of authority or promise, identify each party's liability, and apply the correct defenses.
Key facts
- Principal's Liability: Bound by agent's acts with actual authority, apparent authority, or through ratification. Also liable for agent's torts under respondeat superior.
- Agent's Authority: Actual (express/implied) is given to the agent; Apparent is what a third party reasonably believes based on the principal's actions.
- Surety vs. Guarantor: A surety is primarily liable upon default. A guarantor of collection is secondarily liable, only after the creditor exhausts remedies against the debtor.
- Statute of Frauds: A suretyship promise must be in writing to be enforceable, unless the "main purpose" of the promise is to benefit the surety.
- Key Surety Defenses: Material alteration of the contract, release of the debtor, or creditor's impairment of collateral.
- Exam Focus: Scenario-based questions testing judgment in applying liability rules, not just rote memorization of definitions.
Why Agency & Suretyship Questions Trip Up Smart Candidates
You’ve put in the hours. You can define "surety" and "agent." So why do these questions feel so slippery on exam day?
It’s because the AICPA examiners don't test definitions; they test judgment. They create fact patterns designed to see if you can navigate a web of relationships and liabilities. The most common mistake isn't a lack of knowledge—it's a failure to correctly identify who is liable to whom, and under what specific legal theory.

An exam question won't ask, "What is implied authority?" It will say: "Paula, the president of a corporation, hires Arthur as a general manager. The board did not explicitly authorize Arthur to purchase inventory, but he does so from a regular supplier. Is the corporation liable for the purchase?"
The tempting wrong answer is "No, because the board never gave explicit permission." But the high-scorer knows that a general manager has implied authority to perform acts necessary to run the business, including buying inventory. The liability map is clear: Corporation -> Supplier.

Your Mental Models: The Agency Map vs. The Suretyship Map
Stop thinking of these as two long lists of rules. Instead, view them as two distinct "relationship maps." Your first step in any question is to identify which map you're on.
The Agency Map: A Restaurant Analogy
- Principal: The restaurant owner. They hold the ultimate power and reap the profits or losses.
- Agent: The server. They take orders and interact with customers on behalf of the owner.
- Third Party: The diner. They are contracting with the restaurant.
The core question is always: When is the owner bound by the server's actions?
- If the server takes an order from the menu, the owner is bound. This is actual authority.
- If the owner fires the server but lets them keep their uniform for a week, and the ex-server takes an order from a regular who doesn't know they were fired, the owner is likely bound. This is apparent authority.
- If the server tries to sell the restaurant's walk-in freezer to a customer, the owner is not bound—unless the owner, upon hearing of the great price, later agrees to the sale (ratification).
The Suretyship Map: The Co-Signer Analogy
- Creditor: The bank that issued a car loan.
- Principal Debtor: Your cousin who bought the car and is supposed to make payments.
- Surety: You, the person who co-signed the loan, promising to pay if your cousin defaults.
The core question here is: When can the bank force you to pay?
- As soon as your cousin misses a payment (defaults), the bank can demand the full payment from you. The surety's liability is primary.
- You have rights, too. If you pay, you can go after your cousin for reimbursement (right of reimbursement).
- If the bank and your cousin secretly change the loan from 5% to 10% interest without telling you, your obligation may be discharged due to a material alteration.

The Agency Liability Decision Tree: A Step-by-Step Playbook
When a question asks if a principal is liable to a third party for an agent's contract, run through this mental checklist in order. This is your decision tree under pressure.
Step 1: Was There Actual Authority (Express or Implied)?
Actual authority is the authority the principal intentionally gives the agent. It's the "real" authority.- Express Authority: The principal explicitly tells the agent they can perform the act. Think of it as the agent's "marching orders."
- Implied Authority: The authority an agent has to do what is reasonably necessary to carry out their express authority. A store manager has implied authority to hire cashiers and order routine inventory.
If the answer is YES to either, the principal is bound. Stop here. If NO, move on.
Step 2: Was There Apparent Authority?
This is the most heavily tested and misunderstood concept. Apparent authority has nothing to do with what the principal told the agent. It's all about the principal's communication to the third party. Did the principal's words or actions lead the third party to reasonably believe the agent was authorized?This can be created by giving an agent a title ("VP of Purchasing") or, most importantly for the exam, by a history of allowing the agent to act in a certain way. If the principal consistently pays for an agent's unauthorized acts, they create a reasonable belief in the third party that future acts are authorized.
If YES, the principal is bound. If NO, move to the final step.
Step 3: Did the Principal Ratify the Unauthorized Act?
Ratification is when a principal retroactively approves an agent's unauthorized act. For ratification to be valid:- The agent must have indicated they were acting for a principal.
- The principal must know all material facts.
- The principal must affirm the entire contract.
- The principal must have had legal capacity to authorize the act when it was done and when they ratify.
If YES, the principal is bound. If NO, the principal is not bound, and the agent is liable to the third party.
The Critical Distinction: Implied vs. Apparent Authority
Confusing these two is the easiest way to lose points. They are not interchangeable. Use this table to keep them straight.

| Feature | Implied Authority | Apparent Authority |
|---|---|---|
| Source | The principal's instructions and the agent's position. | The principal's manifestations (words or actions) to the third party. |
| Communication Flow | Principal → Agent | Principal → Third Party |
| Core Question | Was this act reasonably necessary for the agent to perform their job? | Did the principal lead the third party to reasonably believe the agent was authorized? |
| Example | A hired CEO has implied authority to hire key employees. | A fired purchasing agent retains apparent authority until suppliers are notified. |
CPA REG Agency Problem Walkthrough
Let's apply this thinking to a typical REG scenario.
The Scenario: Apex Corp. hires Brenda as a purchasing agent. Her written employment contract explicitly states she is authorized to make purchases up to $50,000. For the past year, Brenda has regularly purchased components from a key supplier, TechParts Inc., with individual orders often reaching $60,000. Apex's accounting department has always paid these invoices without question. One day, Brenda places a $75,000 order with TechParts. The CEO sees the invoice and refuses to pay. Is Apex Corp. liable to TechParts for the $75,000?Let's break it down using the decision tree.
- Was there Actual Authority?
- Express: No. The contract explicitly limited her to $50,000.
- Implied: No. Her implied authority is to act within her express limits.
- Conclusion: Apex is not liable based on actual authority.
- Was there Apparent Authority?
- The Trap: Many candidates stop at step 1 and incorrectly conclude Apex isn't liable. This is the classic "almost right" answer that separates a 74 from a 75.
- The High-Scorer Analysis: Apparent authority isn't about what Apex told Brenda; it's about what Apex's actions communicated to TechParts.
- What did Apex do? For a full year, Apex consistently paid invoices for $60,000—an amount that exceeded Brenda's express authority. This pattern of conduct from the principal sent a powerful message.
- The "Reasonable Belief": This pattern of payment created a reasonable belief in TechParts' mind that Brenda had the authority to make purchases at that level. Apex's actions created the authority.
- Conclusion: Yes, there is a strong case for apparent authority.
A Major Exam Trap: The Principal's Liability for an Agent's Torts
The exam doesn't just test contracts. A principal can also be liable for an agent's torts (wrongful acts like negligence) under the doctrine of respondeat superior ("let the master answer").
A principal is liable for torts committed by an employee (a specific type of agent) if the tort occurred within the scope of employment.
- Key Factors for "Scope of Employment": Was the employee acting to serve the employer's business? Did the act occur during work hours at a work location? Was the act the kind of thing the employee was hired to do?
- "Frolic vs. Detour": A minor deviation from duties (a "detour") is still within the scope of employment. A major deviation for personal reasons (a "frolic") is not.
- Intentional Torts: Generally, principals are not liable for an employee's intentional torts (like assault), unless the use of force is part of the job (e.g., a bouncer) or the employee was acting to serve the employer's purpose.
The agent who committed the tort is always liable for their own actions. If the tort was within the scope of employment, the principal is also liable, giving the injured party two potential people to sue.
A Surety's Rights and Most Testable Defenses
A surety’s promise is strong, but not absolute. The CPA exam loves to test the scenarios where a surety can be released from their obligation.
The Surety's Defenses (The "Get Out of Jail Free" Cards)
These are the defenses you must know cold.| Defense | Description | Impact on Surety's Obligation |
|---|---|---|
| Material Alteration of Contract | The creditor and debtor change the original agreement's terms (e.g., increase interest rate) without the surety's consent. | Gratuitous Surety: Discharged by any material change. Compensated Surety: Discharged only if the change is material and increases the surety's risk. |
| Release of Principal Debtor | The creditor formally releases the primary debtor from the obligation. | Complete Discharge, unless the surety consents or the creditor explicitly reserves their rights against the surety. This is a classic trap. |
| Release or Impairment of Collateral | The creditor has collateral securing the debt and releases it or allows its value to decline through negligence. | Partial Discharge to the extent of the value of the collateral that was released or impaired. |
| Fraud or Duress by the Creditor | The creditor fraudulently or under duress induced the surety to enter the agreement. | Complete Discharge. The surety's promise is voidable. |
| Tender of Performance | The principal debtor offers to pay the creditor in full, but the creditor refuses to accept the payment. | Complete Discharge of the surety. |
A Key Distinction: Real vs. Personal Defenses
The table above lists "real defenses"—defenses related to the contract itself that the surety can use. The exam will try to confuse you with the debtor's "personal defenses," which the surety generally cannot use.- Surety CANNOT Use: The debtor's discharge in bankruptcy, minority, or insanity. The very purpose of a surety is to protect the creditor from these risks.
- Crucial Nuance: A surety can use the debtor's defense of minority or insanity if the creditor was aware of the debtor's incapacity when the contract was made.
- Surety CAN Use: The debtor's own defenses on the contract, such as fraud committed by the creditor against the debtor or breach of contract by the creditor.
CPA REG Suretyship Problem Walkthrough
Let's apply structured thinking to a suretyship problem.
The Scenario: First National Bank loans $100,000 to Swift Logistics LLC. Carol, the owner of Swift, acts as a compensated surety. The loan is secured by a new delivery truck owned by Swift with a fair market value of $80,000. Six months later, the bank, without informing Carol, allows Swift to sell the new truck and substitute an older truck worth only $50,000 as collateral. Swift later defaults. The bank repossesses and sells the older truck for $50,000 and demands the remaining $50,000 from Carol. How much is Carol legally obligated to pay? The Analysis:- Identify Parties & Obligation:
- Creditor: First National Bank
- Principal Debtor: Swift Logistics LLC
- Surety: Carol
- Initial Deficiency: $100,000 loan - $50,000 recovered = $50,000.
- Scan for Defenses: The facts scream "collateral." The bank altered the collateral without the surety's consent. This points to the Impairment of Collateral defense.
- Apply the Specific Rule:
- The Rule: A surety is discharged to the extent of the value of the collateral that was impaired by the creditor.
- The Trap Answer: Many candidates say Carol owes the full $50,000, forgetting the creditor's duties. Another wrong answer is a complete discharge.
- The High-Scorer Calculation:
- Value of original collateral: $80,000
- Value of substituted collateral: $50,000
- Value of impairment: $80,000 - $50,000 = $30,000
- Calculate Final Liability:
- Original remaining debt after collateral sale: $50,000
- Subtract the discharge amount (the impairment): -$30,000
- Carol's remaining liability: $20,000
