Is it legal to translate an article without author&#39;s&#39; permission
<p>There many articles in the web</p>

<p>if I translate an article to another language and put it in another website (with mentioning the source)</p>

<p>will it be illegal to do that?</p>

<p>Do I need author's permission before doing that?</p>

<p>This is illegal unless it is out of copyright under the laws of the U.S. and most other countries, unless you have the permission of the copyright owner.</p>

<p>A few countries allow a translation to be made into one of their national languages if one is not made within a certain number of years and a request to do so does not cause one to be made, without violating their country's copyright laws.</p>
