The terms half-brother and stepbrother are often confused, but they describe different types of family relationships. The decisive factor here is biological relatedness, which also has implications for inheritance law.
The half-brother
A half-brother is related by blood because he shares a common biological parent with the deceased. This relationship can exist through either the mother or the father.
• Example : If the testator’s father has a child with another woman, this child is the testator’s half-brother.
Significance under inheritance law
A half-brother is legally entitled to inherit according to Section 1925 of the German Civil Code (BGB). ” His blood relationship to the deceased makes him a member of the second order of inheritance, ” explains lawyer István Cocron. This entitles him to the statutory inheritance, provided there are no heirs of the first order (children or grandchildren).
The Stepbrother
A stepbrother, on the other hand, is not a blood relative. He is the child of a stepparent from a previous relationship or marriage. There is no biological relationship between the deceased and the stepbrother.
• Example : If the mother of the deceased marries a new partner and this partner brings a child from a previous relationship, this child is the stepbrother of the deceased.
Significance under inheritance law
A stepbrother has no legal inheritance rights, as there is no blood relationship. If the testator nevertheless wishes to leave something to his stepbrother, he must explicitly stipulate this in a will or inheritance contract.
Summary
The key differences between half-brother and stepbrother, and their impact on inheritance law, can be summarized as follows:
• Half-brother :
• Shared parent with the deceased
• Legally entitled to inherit
• Stepbrother :
• No common parent, no blood relationship
• Not legally entitled to inherit, can only be favored through a will
Inheritance law consequences
The distinction between half-brother and stepbrother plays a central role in estate planning. While half-brothers are entitled to inherit without specific provisions from the testator, stepbrothers must be named in a will to become part of the estate. ” This makes it all the more important to carefully consider family relationships when planning an estate, ” says lawyer Cocron.
