An attorney at law (also known simply as an attorney or lawyer) in the United States is a person licensed to practice law by the highest court of a state or other jurisdiction. Alternative terms include attorney-at-law and attorney and counselor (or counsellor) at law. The American legal system has a united (or fused) legal profession, and does not draw a distinction between lawyers who plead in court and those who do not. Many other common law jurisdictions, as well as some civil law jurisdictions, have a separation, such as the solicitor and barrister/advocate split in the United Kingdom and the advocate/civil law notary split in France. There is also no delegation of routine work to notaries public or their civil law equivalent in the American system.

Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of a contingent loss. Insurance is defined as the equitable transfer of the risk of a potential loss, from one entity to another, in exchange for a premium. Insurer, in economics, is the company that sells the insurance. Insurance rate is a factor used to determine the amount, called the premium, to be charged for a certain amount of insurance coverage. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.

A loan is a type of debt. All material things can be lent but this article focuses exclusively on monetary loans. Like all debt instruments, a loan entails the redistribution of financial assets over time, between the lender and the borrower. The borrower initially receives an amount of money from the lender, which they pay back, usually but not always in regular installments, to the lender. This service is generally provided at a cost, referred to as interest on the debt. A borrower may be subject to certain restrictions known as loan covenants under the terms of the loan. Acting as a provider of loans is one of the principal tasks for financial institutions. For other institutions, issuing of debt contracts such as bonds is a typical source of funding. Bank loans and credit are one way to increase the money supply. Legally, a loan is a contractual promise of a debtor to repay a sum of money in exchange for the promise of a creditor to give another sum of money.
