Initially, enclosure was not itself an offence, but where it was accompanied by the destruction of houses, half the (land's annual) profits would go to the Crown until the lost houses were rebuilt (the 1489 Act gave half these net revenues to the superior landlord, who might not be the Crown, but an Act of 1536 allowed the Crown to receive this half share if the superior landlord had not taken action to claim it). In 1515, conversion from arable to pasture became an offence. Once again, half the profits from conversion would go to the Crown until the arable land was restored.
