It means that the borrower and the lender sign a loan contract again under the condition that the old loan has not been paid off, and pay off part or all of the old loan with the new loan. The purpose is to eliminate the debtor's overdue loans.

The example is more popular. In contrast, Company A borrowed 5 million yuan from Credit Cooperative B, and agreed to pay it off by the end of this year. However, Company A was unable to pay it off by the end of this year, so it borrowed100000 from Credit Cooperative B to repay the 5 million yuan that was about to expire.

Please illustrate the principle of rebus sic stantibus in civil law with examples. What does confusion mean in civil law?

"Circumstances change" and "chaos" are both concepts in contract law.

The system of changed circumstances refers to that after the contract is effectively established, the basis of the contract is shaken or lost because of the changed circumstances that cannot be attributed to both parties. If the original validity of the contract is maintained, it violates the principle of good faith and the parties should be allowed to modify or terminate the contract. For example, in the 1970s, Party A signed a land contract with Village B, where Party A rented a piece of wasteland for planting fruit trees. As stipulated in the contract, Party A pays 50 yuan to Village B every year for a lease term of 50 years. A manages the fruit forest well and has made a lot of money over the years. However, with the development of China's economy, the value of 50 yuan today is completely different from that of 50 yuan in the 1970s. Now, if Party A still only pays 50 yuan and Village B, the contract fee will be paid according to the original contract every year, which is obviously unfair and harms the interests of Village B. ..

At this time, the reason for the change of the situation appeared. If we continue to maintain the original effectiveness of the contract, it will violate the principle of good faith and should give Village B the right to modify or terminate the contract.

There are many reasons for this change, such as soaring prices, drastic exchange rate changes, and changes in national economic and trade policies.

Confusion means that the creditor's rights and debts belong to the same person, which leads to the elimination of the contractual relationship in principle and is the independent reason for the elimination of debts. (Articles 9 1 and 106 of the Contract Law have relevant provisions.)
