The Law Foundation of Saskatchewan is a non-profit organization established under The Legal Profession Act, 1990. It receives and manages interest on client funds held exclusively in lawyers' mixed trust accounts, as well as unclaimed funds in these accounts. These funds are intended to benefit the people of Saskatchewan in the areas of legal education, legal research, legal aid, law libraries, and law reform. Pursuant to the legislation, the Foundation provides grants to non-profit organizations that deliver innovative initiatives, increased knowledge, amd access to justice.

Mixed trust accounts contain client funds which are held by a lawyer for a short period of time to facilitate a legal matter, ex: real estate transactions. Individually, the interest earned is generally small and, therefore, it is not feasible to distribute. However, collectively the interest is significant.

The Saskatchewan financial institutions holding the mixed trust funds pay variable rate interest directly to the Law Foundation under special agreements negotiated between the Foundation and the institutions. The Foundation manages these funds pending distribution to grantees. As a result of legislative changes in 2020, the Foundation is now able to invest funds in managed portfolios which include bond funds and equities. In late 2023, the Foundation invested in pooled funds under a revised investment policy administered by a third-party investment firm.

In 2023, the Fund marked its 50th anniversary. Its inception in 1973 makes the Law Foundation of Saskatchewan one of the first of its kind in Canada. It has since distributed over $100 million for its legistaled purposes.
