Consideration
Common law
In common-law systems, a promise is usually enforceable as a contract only if each side gives something of value in return: money, a promise, or giving something up. That 'something' is called consideration.
Compared with: France, Germany, Spain and Italy
Trust
Common law and equity
A trust splits ownership in two. A trustee holds legal title to property, but must manage it for the benefit of someone else (the beneficiary), who has an equitable interest.
Compared with: France and Quebec, Germany, Latin America, Japan
Equity
English law
In England and its former colonies, equity is a body of rules developed by the old Court of Chancery. It adds remedies and doctrines that the common-law courts did not provide: trusts, injunctions, specific performance and more.
Compared with: France, Germany, Spain
Tort and delict
Common law (tort) and Roman-based systems (delict)
Both words describe civil wrongs that cause harm and lead to compensation, outside of contract. Common law builds this out of separate wrongs (negligence, nuisance, defamation and so on). Civil law usually starts from a general rule.
Compared with: France, Germany, South Africa and Scotland
Good faith
Civil law
In many civil-law countries, a general duty of good faith runs through the whole law of contracts: in negotiating, performing and ending them. A court can use it to fill gaps and correct unfair results.
Compared with: Germany, France, Spain, England and the United States
Estoppel

Estoppel stops a person from going back on something they said or did when another person has relied on it. It comes in several kinds, including promissory estoppel and estoppel by representation.
Compared with: Germany, Spain, France
Amparo
Spanish-speaking legal systems
A special court action that lets a person ask a judge to protect their constitutional rights quickly against the government. The Spanish word means 'protection'.
Compared with: Mexico and Argentina, Spain, Colombia, Brazil, Germany
Rechtsstaat
German law
A state in which public power is bound by law, rights are protected by courts, and the administration must act on a legal basis. It is usually translated as 'rule of law', but it carries a slightly different emphasis.
Compared with: France, Spain, Italy
Droit, Recht, Derecho, Diritto
Continental European languages
In French, German, Spanish and Italian, one word covers both 'law' as a whole and 'a right' that someone holds. English has two separate words, law and right.
Compared with: France, Germany, Spain and Italy
Notary
Civil law (Latin notary)
In civil-law countries, a notary is a trained legal professional and a public officer. They draft and authenticate important documents, such as property sales, wills and company documents, which then have special legal force.
Compared with: France and Germany, United States, Latin America and Spain
Prosecutor
Civil law and common law
The prosecutor decides whether to bring a criminal case and presents it in court. The role looks the same everywhere but its legal position differs.
Compared with: France and Italy, Germany, United States
Jury and lay judges
Common law (jury) and civil law (lay judges)

Adverse possession and usucapion
Common law (adverse possession) and Roman-based systems (usucapion)

Civil law splits rights into real rights (rights in a thing, enforceable against everyone, like ownership or a mortgage) and personal rights (claims against a particular person, like a debt).
Compared with: France, Germany, United States and England
Obligation and Schuldrecht
Civil law
In civil law, an obligation is a legal bond between two people, in which one (the debtor) owes something to the other (the creditor). The 'law of obligations' covers contracts, torts and unjust enrichment together.
Compared with: France, Germany, United Kingdom
Force majeure and frustration
French law (force majeure) and English law (frustration)
Both deal with what happens to a contract when something outside the parties' control makes performance impossible or very different. They do it in different ways.
Compared with: France, Germany, England, United States
Stare decisis and jurisprudence constante
Common law and civil law
Stare decisis is the common-law rule that courts follow earlier decisions of higher courts on the same point. 'Jurisprudence constante' is the civil-law idea that a steady line of consistent decisions deserves respect.

A note for translators and students
A comparison here shows the main difference between systems. Real rules vary within a country and change over time, so check the current law of the system you are working in. This is educational, and it is not legal advice.
