In family law matters, the attorney establishes the strategy and executes the plan, but experts often play a critical role in the success of the case. Retaining the right expert is extremely important. As with lawyers, all experts are not created equal. An incompetent or unqualified expert can destroy a case.

Family law is far more complex than is generally understood. It is litigation not unlike business litigation. The Evidence Code and the Code of Civil Procedure apply in family law matters as they do in other types of litigation. A divorce is, to a large degree, the division of the assets of a partnership. The same fiduciary duties exist between parties both before and after separation, as exist in corporate transactions. If civil cases don’t settle, they proceed to trial. The same is true of family law matters.

Divorcing parties can agree to divide assets, resolve issues and settle their differences on almost any basis they choose. However, if they do not settle their conflicts, they may end up in a courtroom. Litigation may involve the testimony of experts. In family law, an expert is an individual who has special knowledge, skill, expertise, training or education that make the expert’s opinions helpful to a family law court on a contested issue.  Experts are almost mandatory in certain situations. The qualifications and credibility of an expert can be critical to the weight given to the expert’s opinions by the divorce court. The early retention of an expert can significantly enhance the chances of a favorable settlement. The experts listed here may be utilized in family law matters.

Courts may not allow experts to testify using case specific hearsay as the foundation for their opinions. This rule may prevent experts from testifying to matters that previously were common place. One example of this issue exists when the expert is to render an opinion and testify in a divorce case as to financial records when the issuing institution has not retained the specific records being relied upon. This problem is not solved simply because the party has the original bank statement, cancelled check or other document, in that those documents are hearsay. To be the foundation for an experts opinion, the documents must be subpoenaed from the institution directly into court.

Art, Antiques and Collectibles  Appraiser

Child Specialists

A forensic psychologist/psychiatrist, known as a “Family Code section 3111 / Evidence Code section 730” expert, may be retained as an expert. This expert will meet with the parties, the children, and collateral witnesses in order to make a recommendation regarding custodial issues and a parenting plan. A forensic psychologist/psychiatrist may be retained by a party as an Evidence Code section 733 expert to attack the report of the “Family Code section 3111 / Evidence Code section 730” expert based on the methodology, logic, and/or protocols used in the preparation of the “3111 / 730” report.

An attorney may be appointed by the court for a child in limited situations. This attorney is not a replacement for an evaluation expert. He/she serves different roles and purposes.

Family Court Services may be appointed to complete a Child Custody Investigation (CCI). A CCI is often used in emergency situations. These investigations address many of the same issues that are addressed in a child custody evaluation, but in a far less extensive and far less expensive manner. These investigations generally involve home visits, interviews with the parties, children, and collateral witnesses. These investigations are more expedited than a “Family Code § 3111 / Evidence Code § 730 evaluation,” do not involve psychological testing, and are generally most appropriate when there is a need to address issues on an urgent basis. However, a CCI is not a replacement for a 3111 / 730 evaluation.

Compensation Expert

The valuation of a business often involves the determination of the reasonable compensation of the operating-spouse.  The allocation of the increase in the value of a separate property business may involve the determination of reasonable or adequate compensation of the operating-spouse. Reasonable compensation can be established by an individual with specialized training in this area. The analysis must be statistically adjusted to reflect the economics of the appropriate geographic area. The analysis will be different depending on which of the two different standards is used.
