After the expiry of ten years, a person may not bring proceedings on a local judgment for the payment of money or return of personal property. In effect, this means that the judgment is good for ten years. See the Limitation Act, S.B.C. 2012, chapter 13, section 7(a).
For information on extensions, renewals and the expiry of foreign judgments, see British Columbia Creditors Remedies: an Annotated Guide, s. 2.27: Action on a Judgment (available in most BC Courthouse libraries and through CLE Online).
