Go to the government sit like (county you live in).gov
Then go to Recorded Docs.
Then put in the address and look up the property and it will tell you if they have been sent the notice of default.
Here in Phoenix Arizona I go to
Then I put in the address or name of the owner and it brings up all the information on the property or person.
You just have to filter trough the files until you find the right one.
Hope this helps you Stan
