Documentation and record keeping are not known as the most enjoyable aspects of being a mental health clinician. Yet, as this chapter explains, they play a vital and important role in meeting one’s ethical and legal obligations. Further, it is explained how timely, thorough, effective documentation can help mental health practitioners to fulfill their obligation to provide the highest possible quality of care. Information is also provided on how clinical records may be needed in the future, and the risks associated with minimal or absent documentation. The role of documentation as a risk management strategy, to meet legal requirements, and to assist in providing high-quality care are each addressed. Specific guidance is provided on the needed components of effective documentation.
