How Attorney-Client Privilege Protects Your Case Strategy

When you engage a forensic psychology consultant as part of your legal team, attorney-client privilege becomes one of your most powerful strategic advantages.

The Privilege Distinction

Not all expert engagements are created equal. Understanding the critical distinction between consulting experts and testifying experts determines what remains confidential and what must be disclosed.

Consulting Expert (Attorney-Client Privilege)

When you hire a forensic psychologist as a litigation consultant:

• All communications protected: Emails, phone calls, strategy memos are privileged
• Analysis remains confidential: Evaluation critiques, psychological insights, strategic recommendations are work product
• Non-discoverable: Opposing counsel cannot compel disclosure of consultant analysis
• Candid discussions: You can freely discuss weaknesses, alternative theories, and strategic pivots

Expert Witness (Discoverable)

Once an expert transitions to a testifying role:

• Reports discoverable: All formal opinions must be disclosed
• Communications may be discoverable: Attorney-expert communications about the case may be subject to disclosure
• Deposition required: Opposing counsel can depose your expert before trial
• Impeachment risk: Inconsistencies or weaknesses can be exploited on cross-examination

Strategic Advantages of Privilege Protection

1. Risk-Free Evaluation Critique

You can have a consultant analyze the custody evaluation without fear that their critique will be discovered if it reveals problems with your case theory. If the analysis supports your position, you can use it. If it reveals weaknesses, you can adjust strategy confidentially.

2. Exploration of Alternative Theories

Privilege allows you to explore multiple psychological explanations for behaviors without locking into a single narrative. You can test theories, gather consultant feedback, and refine your approach—all confidentially.

3. Cross-Examination Development Without Discovery

Consultant-developed cross-examination questions remain protected work product. Opposing counsel never sees your strategic roadmap for exposing their expert's weaknesses.

4. Flexibility to Pivot

If new evidence emerges or the case direction changes, you can pivot strategy without explaining prior approaches to opposing counsel.

Maintaining Privilege: Best Practices

1. Clear Engagement Letters

Your engagement letter should explicitly state:

• The consultant is retained as part of the legal team
• Work product is protected under attorney-client privilege
• The consultant will NOT provide expert witness testimony
• All communications are confidential and non-discoverable

2. Choose One Role - Consulting OR Testifying

Critical: Dr. Tolbert engages as EITHER a consulting expert OR an expert witness, never both. Transitioning between roles creates objectivity problems and risks making all prior communications discoverable. You must decide upfront which role you need.

3. Label Communications Appropriately

Mark emails and memos: "Attorney-Client Privilege / Attorney Work Product / Confidential"

4. Maintain Clear Role Boundaries

Consulting experts provide strategic guidance under privilege and never testify. Expert witnesses provide formal opinions and testimony with all work product discoverable. These are distinct roles that must not be mixed.

When Privilege Can Be Lost

Waiver Through Disclosure

If you voluntarily disclose protected communications or work product to third parties, you may waive privilege. Be careful about sharing consultant analysis with:

• Clients (generally okay, privilege extends to client)
• Opposing counsel (waives privilege)
• Evaluators or other professionals not part of legal team (may waive privilege)

Crime-Fraud Exception

Privilege doesn't protect communications made in furtherance of fraud or crime. This is rarely an issue in custody cases but be aware of the limitation.

Two Distinct Engagement Options

You must choose ONE of these engagement types upfront. They cannot be combined or transitioned between:

Option 1: Consulting Expert (Privileged, Non-Testifying)

Complete privilege protection. Consultant never testifies. All work remains confidential and non-discoverable.

Use when: You need strategic guidance, evaluation critique, cross-examination development, or case analysis—all protected under attorney-client privilege

Advantages: Complete confidentiality, flexibility to pivot strategy, no discovery obligations, lower cost

Option 2: Expert Witness (Discoverable, Testifying)

No privilege protection. All work product discoverable. Expert provides formal opinions and courtroom testimony.

Use when: You need formal expert opinion and testimony to rebut opposing experts or establish psychological facts for the court

Important: All communications, reports, and analysis are discoverable by opposing counsel

Why No Transitions? Converting a consulting expert to a testifying expert compromises objectivity and may make ALL prior privileged communications discoverable, destroying the strategic advantage. Dr. Tolbert maintains strict role separation to protect your case strategy.

Common Scenarios

Scenario 1: Challenging an Evaluation

You engage a consultant to critique the custody evaluation. The consultant identifies serious flaws. Under privilege:

• The critique remains confidential
• You can use the analysis to develop cross-examination
• You can decide whether to hire a testifying expert based on the critique
• Opposing counsel never sees the consultant's analysis

Scenario 2: Real-Time Trial Support

Your consultant attends trial (not as a witness) and provides real-time guidance via text/phone during breaks. Under privilege:

• All communications protected
• Consultant can suggest follow-up questions based on testimony
• Strategic discussions remain confidential

Scenario 3: Expert Vetting

You're considering hiring an expert witness. Your consultant reviews the potential expert's CV, publications, and prior testimony. Under privilege:

• The vetting analysis is protected work product
• You can reject experts without revealing why
• You can confidentially compare multiple experts

Financial Considerations

Privilege protection makes consulting engagement more cost-effective:

• No deposition fees: Consulting experts don't get deposed
• No trial prep time: No need to prepare consultant for cross-examination
• Flexible scope: Pay for exactly the analysis you need
• Settlement leverage: Strong consulting often leads to settlements, avoiding trial costs

Conclusion

Attorney-client privilege transforms forensic psychology consulting from simple expert services into strategic partnership. It allows attorneys to explore psychological complexities, test theories, develop powerful cross-examination, and adjust strategies—all confidentially.

In high-conflict custody cases where psychological dynamics determine outcomes, privilege protection isn't just a legal technicality—it's a competitive advantage that can mean the difference between winning and losing.

Best practice: Choose consulting engagement when you need strategic guidance protected under privilege. If you determine expert testimony is needed, hire a separate testifying expert. This maintains objectivity and protects your strategic development from discovery.
