In certain cases involving the purchase of real property, an individual is charged with inquiry notice. When an individual wishes to purchase land, he ordinarily has the duty under the recording acts to check the title to the property to determine that the land is not subject to any encumbrances, which are claims, liens, mortgages, leases, easements or right of ways, or unpaid taxes that have been lodged against the real property. In some situations, however, the individual must make a reasonable investigation outside of the records, such as in cases involving recorded but defective documents. This type of notice is known as inquiry notice.
