In the legal profession, the term ‘costs’ generally refers to the fees and other expenses a solicitor charges a client for their expertise and other payments that arise out of the provision of legal services, such as court fees.

Costs are one of the most heavily regulated aspects of practising law. Solicitors owe many duties to their clients, such as the duty to disclose and to ensure that legal costs are fair and reasonable. The laws are not only complex but have been frequently amended.

The Law Society of NSW has an educational and regulatory responsibility to ensure solicitors comply with the laws relating to costs. It assists in the settlement of costs disputes and in the investigation of complaints. The Law Society also helps solicitors by providing information and resources.
