I'm not sure I fully understand the situation, but it will be -- at best -- difficult to undo a 25-year old quit claim. There is a statute relating to "omitted assets" that permits a person who left something out of a divorce decree to "partition" it within 3 years of discovering the error -- but it is hard to see how that might apply to your facts, although you indicate your just found out "recently." Consider looking at the 2015 article relating to the Nevada law of partition of omittted assets, which is posted here. Then consider having a consultation with a family law specialist well versed in the subject of omitted assets.
