(a) Unless otherwise directed by a court or prescribed by a provision of this title, a child custody evaluator's actions in conducting a child custody evaluation must be in conformance with the professional standard of care applicable to the evaluator's licensure and any administrative rules, ethical standards, or guidelines adopted by the licensing authority that licenses the evaluator.

(b) A court may impose requirements or adopt local rules applicable to a child custody evaluation or a child custody evaluator that do not conflict with this subchapter.

(c) A child custody evaluator shall follow evidence-based practice methods and make use of current best evidence in making assessments and recommendations.

(d) A child custody evaluator shall disclose to each attorney of record any communication regarding a substantive issue between the evaluator and an attorney of record representing a party in a contested suit. This subsection does not apply to a communication between a child custody evaluator and an attorney ad litem or amicus attorney.
