For get married my documents must be translated??

Helloo everyone!!

I am From Mexico, and my boyfriend is HK native, we gonna get married, he already make research and told me what documents we need for do it and for apply for dependent visa.

My questions is:

1.- All my papers are in spanish, they do not translate, they just make it, every document have official chop and signature from every department in my country. But just like in my "non married certificate"... ppl how would they know my paper say i am not married ??? if is in spanish...

2.- And just want to confirm, i should bring:
- Borning certificate
- Family booklet
- Passport
- Non married certificate

Only that??

And do someone can help me to know, if i can find one copy of the married document?? ( i mean we gonna have only civil marriage, and i supposed lawyer will not give plenty of time for read it, so i want to know the law about this)

If someone can help me with this questions i really will appreciate.
Thanx so much to everyone!!
