In which case would a living will be applicable?

A living will is a legal document that outlines a person's wishes regarding medical treatment and interventions in situations where they are unable to communicate or make decisions about their healthcare. This typically applies in cases where an individual is incapacitated, such as in a severe medical condition or coma.

When someone can no longer make medical decisions for themselves, such as in instances of terminal illness or during surgeries requiring anesthesia, a living will becomes crucial. It guides healthcare providers and family members in making decisions that align with the individual's personal values and preferences regarding life-sustaining treatments or procedures.

The other scenarios listed do not pertain to healthcare decisions or medical treatment directives. Real estate transactions, divorce settlements, and business partnerships involve legal agreements related to finance and property, rather than personal medical care and decision-making.
