Which of the following is a violation of the occupational code?

Abandonment of a contract without legal excuse is a violation of the occupational code because it undermines the legal agreements and relationships formed between parties in a real estate transaction. Contracts are binding agreements that require adherence to the terms stipulated; failing to honor these can lead to significant consequences both for the business and the individuals involved.

When a contract is abandoned without a legal justification—like mutual agreement or a clause permitting cancellation—it can be considered a breach of duty. This not only damages the trust between parties but can also result in legal repercussions, including liability for any damages caused by the abandonment. Understanding the importance of upholding contracts is essential for ensuring integrity and professionalism within the construction and real estate industries.

The other options, while they may involve some ethical or procedural concerns, do not specifically constitute a direct violation of the occupational code in the same manner as the abandonment of a contract. Offering discounts, providing insufficient documentation, and conducting business without a business card may not align with best practices but do not breach specific regulations or legal obligations like abandonment does.
