A more thorough explanation:

Derogation from grant is a term used in legal documents, such as deeds, to refer to a provision that goes against the original grant. This means that the provision diminishes or avoids the rights that were granted in the first place.

For example, if a landlord grants a tenant the right to use a parking space, but then later erects a fence that blocks access to the parking space, this would be a derogation from grant. The landlord is going against the original grant of the right to use the parking space.

Another example could be if a company grants an employee the right to use certain equipment, but then later removes that equipment without providing a suitable replacement. This would also be a derogation from grant.

Overall, derogation from grant is a legal term that refers to provisions that go against the original grant of rights or privileges. It is important to understand this term when dealing with legal documents and contracts.
