To determine if an Affidavit of Disclosure is required there are two questions that need to be answered.

  1. Has the property been subdivided?
  2. Is the property in an incorporated area?

If the answer to both questions is no then an Affidavit of Disclosure is required.  If the answer to either question is yes, then an Affidavit of Disclosure is not required.

To answer the first question, a quick cheat is to review the legal description. If the legal description contains the word “Lot” in it (Lot 20, for example) then the property has been subdivided and an AOD is likely not required.  If you have a metes and bounds legal description (a long legal description like; “The W1/4 Cor Of Sec 17-10S-11E Th S-175.00″…, etc.) then the property has not been subdivided.

To answer the second question, You will need to determine if the property is in an incorporated or unincorporated area. You can usually find this information by doing a parcel search on the Assessors website to determine whether or not the property is within city limits of an incorporated town. Below are links for the Assessors website in each county.
