Which characteristic is NOT true of implied agreements?

Implied agreements are formed not through explicit language but through the actions or conduct of the parties involved. This means that the parties may create an understanding or obligation based on their behavior rather than through formal written documents.

The point that is true about implied agreements is that they do not require written confirmation; they can be inferred from the actions taken by the involved parties. This makes them inherently different from explicit agreements, which typically necessitate formal documentation to be enforceable.

All other characteristics correctly align with the nature of implied agreements. They can indeed be legally enforceable, provided there is enough evidence that demonstrates the existence of the agreement. Additionally, because these agreements are based on actions rather than clear written terms, they may be more challenging to prove in a legal context, as demonstrating the intent and understanding of the parties can require substantial evidence.
