Is a document void if there are missing pages and information not related to case is enclosed instead?

You should have your own attorney review the documents. If you insist on representing yourself, then send a letter or email to the lawyer pointing out the errors and raising the points you want to discuss. You really should hire an attorney.

Contact the district clerk in the county where the divorce was granted. Give the clerk the cause no. at the top of the first page of the document. Buy a copy of the entire document from the clerk. Take it immediately to a lawyer for a consultation. Don 't wait. Thirty days after the judgment is signed, it's too late to do anything.

You should definitely have your own attorney to help you with this. You can call your wife's attorney and tell him/her that there was a mistake in the mailing and get him/her to mail it again or contact the court to get a full and correct copy (if the court has one). If the decree is just a proposed version, you still have plenty of time to have it changed through negotiations or a trial if necessary. If it is a final copy that the judge has already signed, you are on the 30 day deadline mentioned in a previous answer. Again, you definitely need an attorney to help you with this and should hire one ASAP. Best of luck!

I think you are saying the other side sent you a propsosed decree (not signed by the Judge) for your review. Yes, go ahead and do as Attorney Lowry said and send the attorney a letter or email outlining the problems with their proposed Decree, and cite to the appropriate page numbers. The attorney will probably be embarassed that you were sent an incomplete document. If you are supposed to file your objections with the court--make sure you do that too. In some courts the decree is automatically signed if no objections are received within the time frame provided by local rules.
