Part of the law societies' regulatory regime includes an audit function within every law society, and I can use the Law Society of Upper Canada as an example. We have a department that audits law firms on a rotational basis, so every three or four years every law firm in the province is audited. We have very strict record-keeping requirements. We have an annual report that members are required to file every year, and to attest that they have complied with the no cash rule.
