Whether you're using the right start point and picking the right optional pieces are definitely important. But for most kinds of agreements I see and advise on, there's nothing lawyers know that nobody else could know. What you need doesn't have to come from a lawyer, though it often does.

Meanwhile, specifics of the deal and the broader context can also matter, sometime more than the abstractions legal forms tend to deal in. A lawyer may or may not notice those and reason through them.

Paving an AI path over ill-fitting or over-standardized legal terms isn't great for the industry. Neither is reinforcing lawyer monopoly over business knowledge.
