A more thorough explanation:

Solutio Obligationis

Solutio obligationis is a term used in Roman law to refer to the release of a legal obligation. This means that a party who was previously bound by a legal agreement is no longer required to fulfill their obligations under that agreement. It is the opposite of vinculum juris, which refers to the creation of a legal bond.

An example of solutio obligationis would be if two parties entered into a contract for the sale of a car, but later agreed to cancel the contract. The solutio obligationis would release both parties from their obligations under the contract, meaning that the buyer would not have to purchase the car and the seller would not have to deliver it.

Another example would be if a debtor paid off their debt in full. The solutio obligationis would release the debtor from their obligation to repay the debt, and the creditor would no longer have any legal claim to the money.

Solutio obligationis is a legal concept that allows parties to be released from their obligations under a contract or other legal agreement. This can happen for a variety of reasons, such as mutual agreement between the parties or the fulfillment of the obligation. The examples illustrate how solutio obligationis works in practice, showing how parties can be released from their obligations under a contract or debt once the legal bond has been unfastened.
