While approximately 95% of all divorce cases do not require an appearance at trial, having a CPA perform your forensic review for a divorce is to your advantage. 

July 2014 AICPA Forensic & Valuation Consulting Digest describes what Attorneys are looking for in a Forensic Accountant:

Particularly now, due to the recent change to Evidence and Expert Witness of federal rules of evidence, which are generally patterned by the FL state's statutes, sections 90.702 and 90.704, which require certain qualifications from your expert witness and establish standards for the work performed including evidence and documentation of testing and issuing an expert opinion.
90.702 Testimony by experts.—If scientific, technical, or other specialized knowledge will assist the trier of fact in understanding the evidence or in determining a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify about it in the form of an opinion or otherwise, if:

(1) The testimony is based upon sufficient facts or data;

(2) The testimony is the product of reliable principles and methods; and

(3) The witness has applied the principles and methods reliably to the facts of the case


90.704 Basis of opinion testimony by experts.—The facts or data upon which an expert bases an opinion or inference may be those perceived by, or made known to, the expert at or before the trial. If the facts or data are of a type reasonably relied upon by experts in the subject to support the opinion expressed, the facts or data need not be admissible in evidence. Facts or data that are otherwise inadmissible may not be disclosed to the jury by the proponent of the opinion or inference unless the court determines that their probative value in assisting the  jury to evaluate the expert’s opinion substantially outweighs their prejudicial effect.
