What is Constructive Notice?
Constructive notice is a legal fiction that presumes a person has knowledge of certain facts, even if they don't have actual knowledge. In property law, this typically refers to information that is available in public records or is so obvious that any reasonable person should be aware of it.
Key characteristics:
- Applies when information is recorded in public registries (like land titles)
- Deemed to exist regardless of whether the party actually reviewed the records
- Protects third parties who rely on public records in good faith
- Common in real estate transactions and property disputes
Proprietary Estoppel Explained
Proprietary estoppel is an equitable doctrine that prevents a property owner from going back on their word when someone else has relied on that promise to their detriment. Unlike constructive notice, it deals with informal assurances rather than formal records.
Key characteristics:
- Requires a clear promise or assurance regarding property rights
- The claimant must have relied on this promise to their detriment
- It would be unconscionable for the promisor to go back on their word
- Often arises in family property disputes or informal agreements
