Answer:
Add to
Step-by-step explanation:
The text points out that as family members separate and then join new families formed by remarriage, the new kin do not so much replace as ADD TO kin from the first marriage.
This is because Family law assumes that marriages are first marriages. So a new kin from a remarriage tends to be difficult to replace add to kin from the first marriage. A Next of kin refers to someone's closest blood relative and they tend to inherit most of properties of an individual when he eventually dies.
