How to I contest an annulment, what paperwork do I file with courts to contest it

Your question cannot be answered in this forum.  Lawyers.com offers general information and not legal advice.  The specific facts in the case will dictate the type of legal advice offered by an attorney during an office consult.  The grant or denial of an annulment is purely statutory.  It has been my experience that is may be more expensive to pursue an annulment than a traditional divorce. If the Wife is alleging "fraud" as a basis for the relief sought, she must be able to prove this allegation with specificity.  It is often very difficult to prove "fraud" because it will be his word against hers unless there are credible witnesses, evidence, etc., Further, if she is unable to prove facts supporting the claim in the complaint, the court may dismiss the petition.  If the court dismisses the claim, the couple will still have to secure a divorce.  I suggest that your friend confers with an experienced family lawyer in his area to discuss this matter in greater details.  Lawyers charge by the hour; therefore, he needs to discuss the cost of consultation before setting up an appointment. Best of luck~
