Where two or more persons are liable in respect of the same liability, in most common law legal systems they may either be:

adj. referring to a debt or a judgment for negligence, in which each debtor (one who owes) or each judgment defendant (one who has a judgment against him/her) is responsible (liable) for the entire amount of the debt or judgment. Thus, in drafting a promissory note for a debt, it is important to state that if there is more than one person owing the funds to be paid, the debt is joint and several, since then the person owed money (creditor, promisee) can collect the entire amount from any of the joint signers of the note, and not be limited to a share from each debtor. If a party injured in an accident sues several parties for causing his/her damages, the court may find that several people were "jointly" negligent and contributed to the damages. The entire judgment may be collected from any of the defendants found responsible, unless the court finds different amounts of negligence of each defendant contributed to the injury. Defense attorneys should require the trier of fact (jury or judge sitting without a jury) to break down the amount of negligence of each defendant and the plaintiff if there is contributory negligence. Often the court will refuse to do so, allowing the plaintiff to collect from whichever defendant has the "deep pocket" (lots of money), and letting the defendant who pays demand contributions from the other defendants.

n. referring to responsibility of one party for the entire debt (as in "joint and several") or judgment when those who jointly agreed to pay the debt or are jointly ordered to pay a judgment do not do so. A person who is stuck with "several liability" because the others do not pay their part may sue the other joint debtors for contribution toward the payment he/she has made.
