Defending With Informed Consent and Client Direction
The strongest defenses to a professional liability claim are built before the claim exists. They rest on a record showing that options were identified, risks were explained, and the decision taken belonged to the client.

The rule in short
A professional defending a liability claim commonly argues that the client was informed of the options and risks and chose the course now complained of, or that the decision was a considered judgment among reasonable alternatives. Both defenses depend on a contemporaneous record. Informed consent requires that adequate information was communicated, not merely that a document was signed, and judgmental immunity protects a choice made after reasonable inquiry rather than one made in ignorance.
Most defenses to a professional liability claim are assembled long before anyone contemplates litigation. They consist of correspondence, file notes and confirming letters created in the ordinary course, and their value lies in showing what was known, what was explained and who made the decision. A defense constructed after a claim arrives, from recollection and reconstruction, is a weaker thing entirely.
What informed consent requires
Consent operates as a defense where the client, having been given adequate information, agreed to the course now complained of. The definition used in the conduct rules is instructive: informed consent denotes agreement to a proposed course of conduct after the professional has communicated adequate information and explanation about the material risks of and reasonably available alternatives to that course. Each element does work. Adequacy is measured against the decision being made. Material risks must be identified rather than gestured at. Alternatives must be described, which means the professional must have considered them.
The corresponding communication duty requires the professional to explain a matter to the extent reasonably necessary to permit the client to make informed decisions, to keep the client reasonably informed about the status of the matter and to comply promptly with reasonable requests for information. A defense built on consent therefore succeeds or fails on whether these obligations were met, and the evidence for that is documentary.
The practical consequence is a preference for letters over forms. A confirming letter written after a meeting, setting out the options discussed, the recommendation given and the decision taken, addresses adequacy directly. A pre-printed acknowledgment reciting that risks were explained invites the argument that the explanation was thin, and the client's testimony that it was thin will usually be the only other evidence.
Client direction and its limits
Decisions about the objectives of a matter belong to the client, and in litigation the decision to settle belongs to the client alone. A professional who advises correctly and is overruled has generally done what the engagement required. This is the cleanest form of the defense, because it separates the quality of the advice from the quality of the outcome and places responsibility for the choice where the rules place it.
Two boundaries constrain it. The instruction must be informed, which returns the analysis to the first defense: an instruction given without the material facts is not a defense to having failed to supply them. And the instruction must be lawful and consistent with the professional's own obligations. Where a client insists on a course the professional considers repugnant or fundamentally objectionable, the rules permit withdrawal, and a professional who instead proceeds cannot later rely wholly on the client's insistence.
Organizational clients add a further complication. The instruction must come from a person with authority to give it, and the professional must know who that person is. Where a manager directs one course and the board would have directed another, the defense can fail on authority alone. Engagement letters that name the individuals authorized to give instructions, and correspondence addressed to those individuals, resolve the problem in advance. Where a dispute later arises within the client organization, that record is often the only evidence of who decided what.
A common and expensive error is treating documentation as an administrative task deferred until the matter closes. Notes written after a claim is threatened are discounted, and in some circumstances their creation is itself the subject of allegations. The habit that protects a professional is a short contemporaneous confirmation of each significant decision, sent to the client and retained, made while there is nothing to defend.
| Defense | What it asserts | Evidence it needs | How it commonly fails |
|---|---|---|---|
| Informed consent | The client agreed after adequate explanation | Confirming correspondence identifying options and risks | The explanation is shown to have been inadequate |
| Client instruction | The client chose the course against advice | Written advice plus a recorded instruction | No contemporaneous record of either |
| Judgmental immunity | A reasonable choice among defensible alternatives | Evidence of research and deliberation | The alternatives were never identified |
| Scope of engagement | The work complained of was never undertaken | The engagement letter and the conduct of the parties | The professional performed the work anyway |
| Comparative fault | The client contributed to the loss | Withheld information or disregarded warnings | Reduces recovery rather than defeating it |
The judgment defense and its limits
Many jurisdictions recognize that a professional is not liable for an informed choice among reasonable alternatives that proves unsuccessful, or for failing to anticipate how an unsettled question would later be resolved. The doctrine goes by several names and the width varies, but the condition attached to it is consistent: the choice must follow reasonable inquiry. A decision made in ignorance of the alternatives is not judgment, and a failure to research a question that ordinary diligence would have answered is not protected by it.
The defense therefore depends on the same record as the others. A file showing the question was identified, authority was consulted and the options were weighed presents a considered choice. A file silent on all three presents an omission that happened to have consequences. This is the point at which the documentation habit converts into a legal position, and it is the reason the defense is available to some professionals and not to others on identical facts.
Where the underlying question was genuinely unsettled, the defense is stronger still. Courts recognize that a professional cannot be required to predict a change in the law, and several have held that advice consistent with the authority available at the time cannot be negligent merely because a later decision went the other way. The qualification is that the professional must have identified the uncertainty and disclosed it. Advice presented as settled when it was contested is a communication failure regardless of how the question was eventually resolved.
How these defenses fit together
None of them displaces the elements the claimant must prove. Even where consent and instruction are documented, the claimant may still argue that the advice underlying the decision was itself below the standard a professional is held to, or that the work complained of fell outside what was agreed, which returns the analysis to the duty that arises from an engagement. Consent to a course of action is not consent to negligent implementation of it.
A final structural point. Because these defenses depend on documents created during the engagement, they are strongest where the file is complete and weakest where it is not. A professional facing a claim should preserve the file immediately and report before responding to the client, since informal attempts to repair a problem can breach policy conditions and complicate the defense, as described in claims-made insurance and the reporting trap. The defenses described here are available only to a professional who has not already compromised them.
Points to carry away
- Consent is a defense only where the information communicated was adequate for the decision being made.
- Client instructions bind on objectives and on settlement, but do not excuse advice that was wrong.
- The judgmental immunity argument protects an informed choice among reasonable alternatives, not an uninformed one.
- A contemporaneous confirming letter carries far more weight than testimony about what was said.
- Comparative fault reduces recovery where the client withheld information or disregarded advice.
Questions readers ask
Does a signed acknowledgment settle the question of consent?
It helps but it rarely settles anything. Consent is measured by the adequacy of the information conveyed and the client's capacity to understand it, not by the existence of a signature. A short acknowledgment reciting that risks were explained invites the response that the explanation was inadequate. Documents that identify the specific options, the consequences of each and the recommendation given are much harder to attack, because they show what was actually communicated rather than asserting that something was.
What if the client insisted on a course the professional advised against?
That is a strong position for the professional, provided two things are documented: the advice given and the client's decision to depart from it. Conduct rules allocate decisions about objectives to the client, and a professional who advises correctly and is overruled has generally discharged the duty. The defense weakens where the professional continued without confirming the instruction in writing, or where the course chosen was one no competent professional should have implemented at all.
Can a professional defend by pointing to what the successor did?
Sometimes, on causation rather than on breach. Where a successor had a genuine opportunity to correct the problem and did not take it, the defendant may argue that the loss was caused by the later failure rather than the earlier one, or that the claimant failed to mitigate. Courts are cautious with this argument, since a successor's inaction does not retroactively make the original work competent. It is most effective where the remedial step was straightforward and clearly available.

More in Professional Liability
The Affidavit or Certificate of Merit
Merit screening statutes require a claimant suing a professional to file a supporting statement from a qualified practitioner, or a certification that expert proof is unnecessary. The statutes vary in who may sign, what the statement must assert, when it is due and whether the underlying expert must be identified. Non-compliance commonly produces dismissal, and in several states that dismissal operates with prejudice or after the limitation period has expired, ending the claim.
Damages Recoverable, and the Ones That Are Not
Damages in a professional liability claim are compensatory and are measured by the difference between the actual position and the position competent work would have produced. Recoverable items typically include the value of the lost claim or bargain, fees paid for defective work and the cost of correcting it. Emotional distress and punitive awards are generally unavailable absent conduct beyond negligence, and consequential losses must satisfy foreseeability and certainty requirements.
The Standard a Professional Is Held To
A professional must exercise the knowledge, skill, thoroughness and preparation ordinarily brought to comparable work by members of the same profession. The measure is objective and does not require a correct outcome. Because the content of the standard is not within common experience, most jurisdictions require expert testimony to establish it, subject to a narrow exception for failures obvious to a layperson. Holding out as a specialist raises the measure to that of the specialty.
