Step Brother vs. Half Brother
Definition of Step Brother
In simple words, a step brother does not have any blood relationship with you but is only related to you because both or one of your parent got married to another person who does not have any relation to you. The reason of this marriage can be anything such as divorce, death, and other reasons but if in such a case these people are living together as a family then that step brother may or may not be considered as your real brother according to the norms of society but that is not the case according to law. There are other cases that your step brother is living away from you and you get to see them occasionally, but one thing is for sure that both do not have any right to each other’s property. There are fewer chances that they have good relations in this case especially if they got to know each other at a later stage in life. The simplest way of telling what it means is that two brothers who are related to each other because of marriage are known as step brothers.
Definition of Half Brother
This case is different from the step brother because of one particular reason. A half-brother is your sibling because they are related to you because one of your parents married another person, in this way the brother will become related to you by blood because you are sharing the blood of one person from your mother or father at least. There is very less biological difference between the two and the DNA are almost similar. Therefore, they are considered the same in law so that monetary matters can be solved easily but there is no reason to suggest that they are real brothers. In most societies, they are told to be real brothers so that they can bond with each other and less discontentment between them exists. This happens when one of your father or mother dies and the other marries another person. You may or may not live with your half-brother but you know about that person most of the times. In simple words, a half-brother is the one which is related 50% to you by blood.
