Family you didn't choose, sworn in by someone else's heart.

means A relative acquired through marriage rather than blood, such as a spouse's parent, sibling, or child's spouse.

from A transparent English compound of "in" plus "law" — these are the kin who count as family "in law" (by legal bond) but not by birth. The construction dates back centuries; an older form, "mother-in-law," once stretched even to step-relations before the meaning narrowed to those joined by marriage.
