I applied for a divorce based on mental violence.

The decision by the court to allow an expertise or counter-expertise to be prepared depend on many factors including the reasons for the expertise, age of the child, behaviour of the parents and child, if an expertise was already prepared and how intrusive that expertise was. Other factors can also play into this decision.

Fundamentally, the decision to grant a counter-expertise will depend on the judge's appreciation of how the first expertise was conducted. In other words, are there issues, omissions, facts in the expertise that require that more information be gathered. Cross-expertises are usually permitted insofar as the judge is convinced that the request is not made to waste time, would help the court in its decision making process, and would ultimately serve the best interests of the child.
