Anyone who inherits a house, or a company, or even a savings account, does not only get rights. There are also obligations associated with it. For example, if a debt is connected with the house of the grandmother, the son or daughter inherits this debt even with the death of the testator. If you inherit a company, you do not have to take the customers with you. If one remains first at the death of the testator, then the bereaved must pay the funeral. The obligatory parts must pay out the main inheritance to the other survivors, close relatives. Of course, one must not forget the inheritance tax, which calls the state. But the rights of an heir is important, of course.
Will or law decide 
There are two ways in which a survivor can benefit. If the deceased has created a will, this names the heir or heirs. Wills of this kind are created by notaries, such as the notary Neil ( http://notar-neie.de/). If there is no written will of the testator, it is decided by law which close relatives should inherit the property. There are, on the one hand, tangible assets and, on the other hand, monetary assets. If there is a personally determined heir, then the other survivors inherit their so-called compulsory portion. If it is tied up intangible assets, such as in a property, the main estate may be forced to sell the house to pay off the other heir (s). But you can also agree on installment payments to keep the house from the family property.
The rights of the heir in detail
In particular, the heir has the following rights: the property rights, the ownership rights, the
continuation of the tenancy after the death of the tenant and the rights of the heirs. How exactly these rights are defined is a bit complicated. It is possible to get advice from a notary in the individual situation in order to obtain the corresponding rights and, of course, the duties connected with the process of inheritance.
