Which of the following is NOT considered unauthorized practice of law?

Preparing a real estate sale agreement is generally considered part of a real estate professional's duties and does not fall under the unauthorized practice of law, provided the individual is licensed and operating within their professional scope. Real estate agents and brokers are routinely authorized to prepare certain transactional documents, like sale agreements, as part of facilitating the buying and selling of properties.

In contrast, giving tax advice, explaining contract legal ramifications, and interpreting clauses in agreements may require specific legal expertise or qualifications that a non-lawyer may not have. This is why those activities are typically deemed unauthorized practice of law; they involve legal interpretations and advisory that is generally reserved for licensed attorneys. However, preparing a sale agreement as part of a real estate transaction is a standard practice for those within the profession and does not typically require legal licensure.
