(1) The usufructuary lessee may only change the agricultural purpose of the leased property with the prior permission of the usufructuary lessor.
(2) For a change of the use to which the leased property had been put thus far, the prior permission of the usufructuary lessor is required only if the nature of the use will be influenced by the change also after the lease period has ended. The usufructuary lessee may only construct buildings with the prior permission of the usufructuary lessor. If the usufructuary lessor refuses permission, then substitute permission may be given by the Agricultural Court (Landwirtschaftsgericht) upon application by the usufructuary lessee to the extent that the change appears to be appropriate for the maintenance or permanent improvement of the business’s profitability and the usufructuary lessor reasonably can be required to accept it, taking account of their legitimate interests. This does not apply if the lease has been terminated or the lease ends in less than three years. The Agricultural Court may make its substitute permission subject to requirements and conditions, in particular by ordering that security be provided, and may specify the nature and extent of the security. If the reason for providing security has ceased to exist, then the Agricultural Court, upon application, decides with regard to the return of the security; section 109 of the Code of Civil Procedure (Zivilprozessordnung) applies accordingly.
(3) If, in connection with a change of use of the leased property, the usufructuary lessee has substantially reduced the inventory assumed under section 582a at its estimated value, then the usufructuary lessor may demand compensation in money, applying section 582a (3) accordingly, even during the lease period, unless the proceeds of the inventory items alienated have been used for an improvement of the leased property under section 591 that is in a reasonable ratio to the amount of the proceeds.
