Reconstituted family


A stepfamily, blended family or bonus family is a family where at least one parent has children that are not genetically related to the other spouse or partner. Either one parent may have children from a previous relationship. Children in a stepfamily may live with one biological parent, or they may live with each biological parent for a period of time. In addition, visitation rights mean that children in stepfamilies often have contact with both biological parents, even if they permanently live with only one.

A child is referred to as the stepchild, stepdaughter or stepson of their biological parent's new spouse, and that person as the stepparent, stepfather or stepmother of the child.

A stepfather is the husband of one's mother, and not one's biological father. A stepmother is the wife of one's father, and not one's biological mother. A step-grandmother is the wife of one's grandfather, and not one's biological grandmother. A step-grandfather is the husband of one's grandmother, and not one's biological grandfather. A step-uncle is the husband of one's parent's sister (aunt), and not one's uncle. A step-aunt is the wife of one's parent's brother (uncle), and not one's aunt. Similarly, a stepbrother is the son of a stepparent whom one is not biologically related to. A stepsister is the daughter of a stepparent to whom one is not biologically related. A step-grandson is the grandson of one's spouse who one is not biologically related to. A step-granddaughter is the granddaughter of one's spouse to whom one is not biologically related. A step-cousin is the son or daughter of one's aunt's husband (step-uncle) or uncle's wife (step-aunt) who one is not biologically related. A parent's spouse of the same sex may also count as a stepparent.

Alternatively, in Australia Under the Family Law Act 1975 (Cth) a "stepparent" in relation to a child, is interpreted as a person who is not a parent of the child; and is, or has been, married to or a de facto partner of, a parent of the child; and treats, or at any time while married to, or a de facto partner of, the parent treated, the child as a member of the family formed with the parent.

A "simple" stepfamily is one in which only one member of the couple has a prior child or children and the couple has not yet had additional children. When both members of the couple have at least one pre-existing child, the new family is "complex" or "blended" from the start; if only one member has one or more prior children but the couple has another child together, the "complex"/"blended" designation replaces the "simple" designation upon the birth of the new child. If both members of the couple have prior children, those children are stepbrothers and stepsisters to one another. Any subsequent child born to the couple is a half-sibling of the respective members' prior children.
