In addition to the above information, some lenders add additional reserves to a credit agreement. Here, too, credit conditions must be clear. The loan must approve the terms of the document. Both the borrower and the lender sign the agreement when the project is complete. A witness is recommended, but not always a legal necessity. A lender and/or borrower must find out the laws in which you reside to see if a witness or notary should see that the parties are signing the document, so both parties must provide proof of identity before signing before a notary. A person is a notary if the State has granted them a licence to perform such a role. The role of the notary is to ensure that there is no fraud during the official signing of the document. .
