I am looking for the same thing, I seached internet recently, seems there is a good lawyer, but I guess the lawyer fee won't be cheaper

There is another website:
http://www.divorcecanada.ca about that, hope helps.
I guess you can do that by you two as long as you already have the agreement.
Different person has different case, like to me, kind of complex, if you know anywhere can help, can you please post out?
Thanks!
