I can pull title reports online for you, as all reatlors in the Sacramento area have access to the realist information. You can also go to the county recorder's office, located at either Madison and Hazel, (in Fair Oaks) or at 600 8th street (downtown Sacramento).
Obtaining all of the records would sound to me like a first step in investigating what has been happening on any property that you have in question. If there appears to be any fraud or misrepresentation, then you would need to contact an attorney, (for civil actions). or the police (for any criminal actions). The County recorder's office can also advise you on a direction to pursue, should your former spouse had presented a false document in order to file a transfer of ownership.
