in-law relations

Spouse's family members

In-law relations are family members connected through marriage rather than blood—your spouse's relatives and the spouses of your blood relatives.

The term covers parents-in-law, siblings-in-law, and their extended families.

These relationships carry social expectations but lack the biological ties that typically define kinship: Her in-law relations were cordial but distant.

The phrase often implies obligatory rather than chosen connections.
