The disclosures are not filed with the court. If she has a copy of the disclosures then it should show it. If she waived the final disclosures then you can argue that she assumed the risk.
This is just my opinion and not a comprehensive answer. You assume the risk because this answer may not apply to your situation depending on the facts.
As the party alleging the failure to disclose the asset, the burden of proof should be on her to show it. In addition, she has to show a willful intent to conceal it. You would want to think of instances where you discussed this particular asset, that she had full knowledge of it. i.e., statements re this asset coming to your former home, inclusion of information of the asset on tax returns she signed....in short any documentation or witness you can find that has any relation to this asset that she would have had knowledge of or involvement with. The request for 100% of those assets is intended to be punitive for your alleged active concealment of the asset involved. That aspect of the law is intended to discourage people from hiding assets. While I haven't checked, I believe that the standard of proof on this type of issue is one of "clear and convincing" proof of your intent to conceal it, not simply proof of that by a preponderance of the evidence. These are technical aspects of the evidentiary laws and not something a layperson would likely be able to handle. If the asset is of significant value or importance, you should hire an experienced family law attorney.
