1. Lenders and borrowers must meet the basic conditions and provide the documents needed for private lending, the most common one being the ID card. If there is a guarantor, the ID card of the guarantor shall also be provided. 2. Agreed loan principal and interest: If the interest rate agreed between the borrower and the lender does not exceed the annual interest rate of 24%, the people's court shall support it. The interest rate agreed between the borrower and the borrower exceeds the annual interest rate of 36%, and the interest agreement in excess is invalid. 3. Guarantee procedures: For loans with large amount or high risk, the guarantee and mortgage procedures shall be performed, and the borrower shall be required to provide a third party with certain economic strength as a guarantee, or personal property such as certificates of deposit, bonds, motor vehicles and real estate shall be required as collateral, and a written loan agreement shall be concluded. 4. Conclude an agreement: In real life, some lenders often do not issue written documents when borrowing money because the other party is a relative or friend, out of affection or out of trust. In this way, once the borrower denies it, it is difficult for the lender to protect the creditor's rights. Even if you go to court, you will end up losing because you can't prove it. Therefore, the lender must conclude a written loan agreement with the borrower, indicating the name, loan type, currency, amount, time, term, purpose, interest rate, repayment method, guarantor and liability for breach of contract, and sign it, with each party holding one copy and keeping it properly. It should be noted that in the process of dealing with private lending, lending should be legal, and only legal lending relationships can be protected by law. For example, the source of funds should be legal, the purpose of borrowing should be legal, and the way of borrowing should be voluntary, not violent means and the agreement on interest should be legal, generally speaking, it should not exceed 24%.
