Berlin will for married couples: When it makes sense and what difficulties there are. If a partner dies, potential children are initially left empty-handed.
The legal succession does not apply if the partners have decided on a Berlin will. Unmarried couples cannot make use of the Berlin Will. If the inheritance consists mainly of a property, the person who lives longer can continue to live there unmolested. There are no heirs to pay out, so there are no disputes at the moment. If you want to regulate what happens to real estate and assets after your death, you should create a will.
