I have seen many parties botched up their sure winning cases just by reading online. I hope your case will not be same. If you want to produce any documents signed or sent by your wife or her parents, the proper stage was when they appeared as prosecution witnesses and you should have shown those documents and confronted them with the veracity of the contents of the documents. Anyhow, water has flown under the bridge. Now, file all those documents and bring defence witnesses. There is also one other way to prove the documents filed by the wife in different case. To summon those documents from the concerned court. But whether you should produce documents or bring defence witness in criminal cases will also be depending upon that how much the prosecution succeeded to prove the case. But once you appear in witness box, opposite counsel has got the right to cross examine you on the facts which you say and also on the facts contained in the documents you produce. Hope you and your advocate understand this procedure.
