need to know my husband filed and i answered now i want to contest it. I also need to find out how much he makes hrly, and how much he has u=in his ira. We were married 28 years i think i should be entiled to half right?

Not necessarily. Not all states have community property laws. Any question on law needs to include your general locale as laws vary by area.

As far as finding out how much he makes. Subpoena his pay stubs and IRA statements. You may have to have the subpoenas served on his employer and financial institution(s).

This needs a LOT more clarification.

Are you living separately?
You have to be married, or if divorced, divorced part way through the year.
But you say you WERE married.
What did you 'answer?' Do you mean he pays alimony? If you are divorced and he doesn't give you any money, then he can't claim anything about you, and you aren't entitled to know anything about his income.
If you are divorced and he gives you money, I'm still not so sure you are going to be able to get his income information.

I took it to mean the husband filed for divorce. I'm guessing the divorce wasn't finalized. However, if it was, then the OP will have to prove that income and assets were hidden during the proceedings.

You really can't stop a divorce if he really wants it. Nor could he stop it if you wanted it.

Now for the rest... thats where the devil is in the details.

Assuming you are in America, you will not stop the divorce, but can slow it down.. but though the court, you require him to provide all of his details,

But as noted, if you think, he is hiding money or income, it will be up to you, to find it and prove it

I don't think that she's trying to stop it. Contesting the divorce in this case isn't trying to prevent it but is saying that she doesn't agree to the terms of the divorce. Make sure you're prepared and have all the information you need to support any claims in the divorce.
