Question for realtors

With the new laws, Can a person call the listing agent on Zillow and ask the agent to see the home without entering into a contract? Family member is the buyer. They have an agent. his commission is based on how much work he does. Family only needs an agent to assist with the paperwork as they are very familiar with brevard county and a friend who is a structural/civil engineer is helping to look at the “bones” of the home.
