A more thorough explanation:

Definition: Fresh disseisin is the act of wrongfully depriving someone of their freehold possession of property, also known as dispossession. It is a legal term used in property law.

For example, if someone forcefully takes over a piece of land that belongs to someone else, they have committed fresh disseisin. The person who has been wrongfully deprived of their land has the right to forcefully eject the disseisor from the land without resorting to law, as long as the ejection occurs soon after the disseisin.

Another example of fresh disseisin is when a landlord locks a tenant out of their apartment without following the proper legal procedures for eviction. This is considered fresh disseisin because the tenant has been wrongfully deprived of their possession of the property.

Overall, fresh disseisin is a serious offense in property law and can result in legal action being taken against the disseisor.
