Your first step is to  identify the jurisdiction (e.g., Canada, Nigeria) and the type of source (e.g., case, legislation, etc.).

Refer to Bluebook TW (Foreign Jurisdictions).

After you have identified the jurisdiction and type of source, consult a research guide on how to find the source.

For more information, see the library's Foreign Law Research Guide.

A note on translations

Official translations are difficult to find and often out of date - if they even exist. Do not rely on Google translate.
