Final answer:
Express contracts and implied in fact contracts have different rules and requirements. Express contracts are formed through explicit communication, while implied in fact contracts are based on conduct and behavior. Both types of contracts are legally binding.
Step-by-step explanation:
Yes, different rules apply to express and implied in fact contracts. Express contracts are formed when the parties explicitly communicate their intentions and agreement, whether orally or in writing.
Implied in fact contracts, on the other hand, are based on the conduct and behavior of the parties involved rather than explicit words or written agreements. Although both types of contracts are legally binding, there are some differences in the rules and requirements that apply to each.
