What are the different types of expert witnesses?

There is a wide range of expert witnesses that can be narrowed down by: 

1. Area of expertise: This is the broadest category and encompasses experts in any field that can offer knowledge beyond the judge or jury’s experience. Examples include medical doctors (medical malpractice), engineers (construction accidents), or financial analysts (securities fraud).
2. Testifying vs. Non-Testifying: Testifying experts take the stand and deliver their opinions in court. Non-testifying experts (non-participant expert) assist lawyers with case preparation by analyzing evidence and formulating strategy, but they don’t appear in court themselves. Essentially non-testifying experts are participant experts. 
3. Joint Litigation Experts: These experts are hired by both parties in a case to provide a neutral assessment. This can be useful for complex issues where both sides can benefit from an objective analysis. This can stop expert battles between parties. It can save time and money.
4. Litigation Experts: This is a more general term for any expert who is involved in a lawsuit, regardless of whether they are hired by one side or jointly.

It’s important to note that these categories aren’t strictly defined, and there can be some overlap.

The key thing is that expert witnesses provide specialized knowledge to assist the court in understanding complex issues

What are the six requirements for expert reports?

1. Expert Qualifications: Similar to other jurisdictions, the report should detail the expert’s qualifications relevant to the case (education, experience, certifications). 
2. Instructions Received: The report should outline the specific questions or instructions the expert was given by the party who retained them. This aligns with Rule 53.03 of the Ontario Rules of Civil Procedure.
3. Scope of the Report: This section should clearly define the issues the expert will address in their report, ensuring their opinion stays relevant to the case.
4. Expert’s Opinion: The core of the report, it presents the expert’s well-reasoned professional opinion on the identified issues.
5. Expert’s Basis for the Opinion: This section justifies the expert’s opinion by detailing the reasoning behind it. It should include:
   • Factual assumptions made by the expert
   • Research conducted (if any)
   • References and data relied upon

        6. Disclosure of Conflicts: Transparency is key. The report should disclose any potential biases or conflicts of interest the expert might have.

Additional Considerations:

• It is important to provide the court with a fair, objective, and non-bias opinion.
• While not an explicit requirement, ensuring the report is written in clear and understandable language is crucial for the court to grasp the expert’s opinion effectively
  

What rule governs the use of an expert for decison-making or parenting time claims?

Rule 20.2(8) provides that, unless the court orders otherwise, only a joint litigation expert may present litigation expert opinion evidence concerning decision-making and parenting claims under both the Divorce Act and the CLRA. 

What happens if a joint expert is not feasible?

The court may appoint its own expert or permit each party to hire separate experts under Rule 20.3.

Under what situations might a judge do this?

• the parties cannot agree on a joint expert
• the court determines that a joint expert is inappropriate or impractical in the circumstances

How do the rules affect hiring their own expert after hiring a joint one?

Rule 20.2(13) provides that where a joint litigation expert provides opinion evidence on an issue for a party, no other litigation expert may present evidence on that issue for that party, unless the court orders otherwise.
