## SA 299 – Responsibility of Joint Auditors

### What is a Joint Audit?

A joint audit is when two or more audit firms are appointed together to audit the same entity.

---

### Advantages vs. Disadvantages

Advantages	Disadvantages
Pooling and sharing of expertise	Fee sharing between firms
Benefit of mutual consultation on complex issues	Psychological tension when firms of different standing are paired
Lower workload per firm	Coordination challenges
Healthy competition improves performance	Lack of clear division of responsibility

---

### Division of Work

1. Decided by mutual discussion between all joint auditors

Usually by identifiable units or specified areas
Sometimes by assets/liabilities/income/expenditure
Critical areas are covered by all auditors jointly — not split

2. Division must be documented and communicated to the client

---

### Coordination Between Joint Auditors

Each joint auditor must share significant information with the others when it:

Deserves their attention
Requires disclosure in the financial statements
Requires mutual discussion
Requires the application of judgment by other auditors

Coordination must occur before finalization of the audit.

---

### Responsibilities — The Critical Distinctions

Scope of Work	Nature of Responsibility
Work allocated to each auditor	Each auditor is responsible only for their own allocated work
Evaluation of internal controls	Each auditor is separately responsible for IC over their own allocated area
Work not divided (undivided work)	All joint auditors are jointly and severally responsible
Collective decisions on nature/timing/extent of procedures	All joint auditors are jointly and severally responsible
Matters brought to the notice of the joint auditors by any one of them	All joint auditors are jointly and severally responsible

> Joint and several liability means any one auditor can be held liable for the entire obligation — not just their portion. This is why coordination and communication are critical.

Worked example

### Example 1

Scenario: Firm A is assigned inventory and Firm B is assigned trade payables in a joint audit. During Firm A's work, they uncover a major related-party transaction that affects both areas. What must Firm A do?

Answer: Firm A must communicate this to Firm B under the coordination requirement — it 'deserves their attention' and 'requires mutual discussion.' Both firms must address this jointly before the audit is finalized. Failure to share this information could expose both firms to joint and several liability for any resulting audit failure.

### Example 2

Scenario: In a joint audit, Firm A detects misstatements in the area allocated to Firm B but does not communicate the finding. Firm B signs off without detecting the error. Who bears responsibility?

Answer: Firm A had a coordination duty to share information that deserves other auditors' attention. By not communicating, Firm A breached this duty. Since all joint auditors are jointly and severally responsible for matters brought to their notice, and Firm A was aware, both firms may be held liable — not just Firm B.

⚠️ Common exam mistakes

Assuming each joint auditor is equally responsible for all work — each is responsible only for their allocated work, but jointly and severally liable for undivided work and collective decisions
Forgetting that critical areas must be covered by ALL auditors — they cannot be assigned exclusively to one firm
Overlooking the requirement to document the division of work AND communicate it to the client — both steps are mandatory
Assuming coordination can happen after the audit is finalized — coordination must occur before finalization
Confusing 'joint and several' with 'shared equally' — joint and several means each party is independently liable for the full amount, not just a proportional share
