What is forfeiture?
If the tenant breaches the terms of the lease then the landlord has the right to forfeit the lease which means bring it to an end. If the breach is non payment of rent and the premises are used for business purposes then forfeiture can be effected by the landlord re-entering and simply changing the locks generally speaking bailiffs would be employed for this purpose. Alternatively the landlord can obtain a court order first.
Though criminal forfeiture laws vary from state to state, generally, the government may seek criminal forfeiture when the property is used in the commission of a criminal offense, or was obtained through criminal activity. For example, the government may ask the court to allow it to seize an automobile purchased by a defendant with the proceeds of an inside trading scheme. The government also may seek forfeiture of money or bank accounts if it proves that the money was used in the commission of a crime or is the proceeds of a crime.
