Section 16(1) KlGG concerns reimbursement for expenses necessary or useful for garden use. It refers, among other things, to fruit trees, shrubs and other crops. For buildings, reimbursement under this provision requires construction in compliance with building regulations.
The relevant value is the current value of the expenses. That value may not exceed the expenditure actually made. A transfer payment therefore cannot be justified only by the former subtenant's desired price. The specific item, its legal basis, condition and supporting evidence must be identifiable.
Section 16(2) KlGG provides special consequences where the sublease ends by expiry and the land is to be used for another purpose. That situation must be distinguished from an ordinary takeover of a garden house and reviewed against the term of the contract and any statement by the general lessee.
