In Maryland, it is assumed that both the mother and the father have equal rights over the minor child. The law has not been framed in a manner that favors custody to be granted to one guardian and not the other. Though both are considered natural custodians of the minor child, it is the best interest factor that determines which guardian will be given custody of the child. The best interest of the child is an analysis made by the court to find out what is best for the child. Even in cases involving third parties like grandparents, the best interests of the child is the important factor that determines minor guardianship. A custody order can never be considered permanent as it keeps changing as per the change in circumstances.
