This is true on both sides of every transaction, buying and selling, and the Law Society of Saskatchewan regulates who is qualified to handle it. There is no cash, no-lawyer path available the way some US states allow for a simple transaction.
Expect to budget $800 to $1,500 in legal fees for a standard purchase or sale, more if the transaction involves an estate, a mortgage discharge, or multiple owners on title.
Skipping this step is not a shortcut available in Saskatchewan, so the real question is which lawyer, not whether you need one. Get your hand-reviewed valuation from Joel Dyck.
