Final answer:
The purchaser's right to acquire legal title to real property under the terms of a valid agreement is based on property rights and contractual rights. Property rights allow individuals and firms to own property and use it as they see fit, while contractual rights enable them to enter into agreements with others regarding the use of their property.
Step-by-step explanation:
The purchaser's right to acquire legal title to real property under the terms of a valid agreement is based on property rights and contractual rights. Property rights refer to the rights of individuals and firms to own property and use it as they see fit. Contractual rights allow individuals to enter into agreements with others regarding the use of their property and provide recourse through the legal system in case of noncompliance.
For example, if a person wants to purchase a piece of real property, they would enter into a valid agreement with the seller. This agreement would outline the terms of the purchase, including the transfer of legal title to the buyer. Once the agreement is executed and all conditions are met, the purchaser acquires the right to legal title to the property.
It is important for both parties to have a clear understanding of their rights and responsibilities under the agreement. Any disputes or disagreements can be resolved through the legal system, which enforces contracts and protects the rights of both parties.
