in accordance with § 1199 BGB Ren­ten­schuld­brief

(1) A land char­ge can be crea­ted in such a way that a cer­tain sum of money is to be paid from the pro­per­ty at regu­lar­ly recur­ring inter­vals (annui­ty debt).

(2) When the annui­ty debt is crea­ted, the amount must be deter­mi­ned by the pay­ment of which the annui­ty debt can be rede­e­med. The redemp­ti­on amount must be spe­ci­fied in the land regis­ter.

In prac­ti­ce, this land char­ge is used as a life annui­ty for the pur­po­se of reti­re­ment pro­vi­si­on. A fixed sum of money is to be paid at regu­lar inter­vals from an encum­be­red pro­per­ty.
This con­s­truct is also used in agri­cul­tu­re. Far­mers are thus able to satis­fy their cre­di­tors from cur­rent inco­me.
