What will I do when I was denied the petition for naturalization because I was not able to produce the document? This was back in 1988.

The question would appear to be the relevance of the divorce document. If it was not relevant to the question of your qualification for naturalization, you can submit a new application. If it is germane to the qualification, you should obtain it either by the time that you file for naturalization or by the date of your interview.
