Which type of family is typically formed by choice and not legality?

The type of family that is typically formed by choice and not legality is a partnership. Partnerships come together based on mutual agreement and emotional connections between individuals, rather than through legal formalities or regulations. This can include romantic relationships where couples decide to live together and share their lives without necessarily formalizing this through marriage or civil partnerships. It emphasizes personal choice and the significance of the relational bond rather than legal obligations.

In contrast, other options like common law families or civil partnerships are recognized legally to varying extents; they often come with specific legal rights and responsibilities, indicating that a formal legal structure is involved in their formation. A single-parent family is primarily defined by the presence of one parent raising children and doesn't inherently signify that the formation was built on choice outside of legality. In summary, a partnership exemplifies family formation based solely on personal choice and emotional commitment rather than legal recognition.
