Final answer:
In situations where a contract exists without the opportunity for negotiation of payment terms, it is known as an implied contract, upheld through an individual's contractual and property rights.
Step-by-step explanation:
When a court determines that there was a contract between two parties in a situation where there was no opportunity to negotiate payment, the contract between the parties is known as an implied contract. An implied contract is created by the actions, behavior, or circumstances of the parties involved, rather than through a written or spoken agreement. Contractual rights and property rights are the fundamental legal concepts that enable individuals to make arrangements about the use of their property, ensuring that they have recourse through the legal system in cases of noncompliance, such as non-payment for services provided.
