Even if the husband did not appeared before the court then also the court must have passed an exparte order. Ask her to produce the said order instead of attorney statement.

if there is no order from the court then your marriage will be void since she will be considered to be married at the time of her marriage with you.

regards

See in case she got exparte annulment decree then in that case marriage is valid. She can legally remarry.

if she got divorce decree then she can remarry legally. 

Your marriage with her would be void, if your wife does not have a degree of an annulment from a court having competent jurisdiction. Attorney statement has no value in the eyes of law, in absence of a valid degree of annulment

if family court had passed order for anullment and no appeal was filed by her ex husband she was at liberty to remarry after anullment decree was passed 

1. Wife is practically saying that she filed a petition for annulment whereupon court issued summons to her husband but her husband did not contest the case, hence court granted ex parte decree in her favour.

2. She was free to remarry after the lapse of limitation period to challenge ex parte decree of annulment.

You have actually review the copy of annulment of marriage order by court without that how can you will prove later that she has nullity or nullify her previous marriage. Till the time she can't prove this than your marriage with her will be void and not valid.

You can't believe till you see the court order. Apply the copy of order from the court to confirm

She should have provided you the details. Attorney statement don't amount to much. Why is she hesitant. Maybe there was no annulment and there was a bitter divorce. Find out for your self through a detective.

1. If she had not availed the decree of annulment/divorce from her first husband before marrying you, then her marriage with you shall be considered as void at law.

2. Mere filing a petition for annulment of marriage does not pass the decree of annulment or divorce.

3. If she has not taken valid divorce from her first husband, then a charge of bigamy can be brought against both of you which is punishable u/s494 of IPC punishable with jail term for maximum period of 7 years with or without fine.

Ask her to bring dissolution order by court otherwise court will annul the marriage due to subsistence of previous marriage.

File application in court to summon dissolution order.

As rightly stated by you until the order passed in her petition is perused, it cannot be clarified. 

If she have obtained Ex-parte order for annulement of marriage through divorce and it was not opposed by ex-husband.

Then your marriage will not be considered void. And she was free to marry again. 

Without dissolving the previous, contracting a marriage again with another person will not make this new marriage valid as per law.

Until you have not confirmed about her divorce of the previous marriage, you may not form any opinion about it.

Dear Sir,

No, she cannot marry without divorce or annulment of marriage.
