Get variable Title for a line

Hey,

Here is the beta version of the new website of my collective
http://collectifsaga.com/X/wordpress/fr/home/

My website is multi language, but un the footer, I have some links, that I had by myself

here is the code in footer.php

<div class="footer-area clear">

		<a href="http://collectifsaga.com/X/wordpress/mentions-legales/">legal notice</a>
		-
		<a href="http://collectifsaga.com/X/wordpress/saga-ca-gaze/">about saga</a>
		-
		<a href="mailto:[email protected]">contact us</a>

		</div><!-- .footer-area -->

That’s quite basic. The thing is that I’d like to have the name of the link “about saga” or “legal notice” in french when it’s french version, english when it’s english version …

I guess that that the solution if to get the variable Title of the article “legal notice” (EN) or “mentions légales” ‘(FR)

Do you have an idea how to solve this problem ?

Thank a lot of this wonderful community
