L grants a lease to T:
In consideration of T agreeing not to exercise the break right,
L agrees to reduce the rent to £80,000 a year.
Whether that agreement (not to exercise the break clause) is
documented as a variation to the lease to remove the break right,
or simply as a payment for T’s agreement not to exercise the
right, there is an acquisition by T.
However, T has not given any chargeable consideration for the
acquisition (as the giving up of a right is not consideration in
money or money’s worth under FA03/SCH4/PARA1). Therefore no
stamp duty land tax is due and the transaction is not
notifiable.
