Police reports of any country are acknowledged worldwide?

Suppose in Canada, where a wife tries to commit suicide and survives (living with her husband and in-laws). Her husband takes official statements from police, psychiatrist, lawyer, doctor stating that his wife attempted to commit suicide alone, no family member or any other person was involved.

But, if her family, residing in any other country, files a case against her husband's family (e.g. from China, Australia, Pakistan, United Kingdom etc)..
Does another country's courts and laws will acknowledge the official statements and documents of Canada or its worthless?

Plz guide. Thanks.
It depends on the country. Some yes, some no, but it's never 'automatic.' A lot of it will have to do with if the judge believes the statements are true and not resulting from coercion.
They will acknowledge the documents of another Court be it in the country or out as long as the document can be establihed as a certified copy from the court.


Answers:
Rules of the sovereign. Odds are any police report could be used as evidence. But, weak evidence. It would be up to the judge if in court, or the police officer on the street.

But a report or conviction in another country typically has no standing or value in another country.
They'd still be admissable. But they would only prove what they said. Not any act of guilt. It would be like saying 'see, it says here that So and So knew she did it by herself,' and not 'The police in Canada said this so you must convict.' It would only do a little bit as far as evidence goes.
