Definition:
Constructive notice is a legal term meaning that persons are assumed to have knowledge of something by virtue of the fact that it is in the public record. This principle means that someone cannot deny knowledge of a fact because they have a duty to inquire.
For example, if you purchase property, you are presumed to know the legal status of that property because it is available through public records.
In another example, the symbol ® provides constructive notice that a trademark or service mark has been registered and that it is not in the public domain and thus available for anyone to use.
