I want to use the fonts available in http://font.ubuntu.com/ in my personal website, but I dont know what text I have to include in "Legal Information & Notices" section of my website. I have found This but I have doubt if are this text, part of this, or another. Thank You :)
I've read the licence you link to and I think you're quite okay to use the font freely on your website. The following parts of the licence are relevant:
I would say that for the purposes of this clause, your website is a 'document'.
Next relevant part:
This is pretty much self-explanatory - note the explicit reference to using the font as you would any other.
Last up is this:
Again, I would class web pages as 'documents'. Support is lent to this interpretation by the fact that there's no exclusion of web pages from the lists given in the extracts above.
In conclusion, I think you're free to use the font on your website.
PS: I am a lawyer.
EDIT: you don't have to put a reference to the licence on your website. You might want to attribute the font to Ubuntu, but you're not obliged to.
