I'm from california and I'm trying to get my marriage annulled based on fraud, where he withheld information from me prior to, and during the marriage. Did not know that he had a son, nor did I know of the fact that he had other assets such as apartment lease on his name and purchased of a car. My questions are:

1) do those three reasons consitute as fraud for annullment?
2) and if it does, what are the process that goes through an annulment?
3) lastly how long does the whole entire process take till the annulment is official if its uncontested from the other party?
