What is the law of obligation?

The law of obligation refers to a person’s legal duty to do something. This legal duty arises in situations where a person, or a group of people, is required to take a particular course of action under the law. These kinds of obligations are binding ties that are covered by legal terms and can be enforced by a court. 

While legal obligations are commonly accepted and understood in situations where contracts are exchanged, promises are made, or oaths are taken, there are also a number of legal obligations that people are required to adhere to as part of everyday life. For example:

The law of obligation applies across all of the UK’s legal systems, including English law, Scottish law, Northern Ireland law, and Wales law. It is present in all legal jurisdictions and areas, including:

  • common law.
  • civil law.
  • private law.
  • comparative law.
  • commercial law.
  • international law.
  • property law.
  • public law.
  • constitutional law
  • administrative law
  • competition law.
  • criminal law.
  • intellectual property law.
  • company law.
  • family law.
  • tort law.
  • human rights law.

What is the difference between obligation and duty?

While obligation and duty are often used synonymously in everyday language, they are technically different things when discussed in a legal context. 

Obligations are the legal rules, requirements, and scenarios in which people are required to do something. Duty, meanwhile, refers to the action that a person must perform in order to meet an obligation. 

For example, there is a legal obligation to follow the Highway Code in the UK. This means that all motorists on UK roads have a legal duty to obey speed limits, wear seat belts, and ensure both driver and vehicle are in fit condition for the road, as required by the code.

What are some of the sources of obligation?

Contracts

The law of contract is one of the most commonly understood sources of obligation. Contractual obligations are outlined in the contract agreed between two – or more – parties, with each party duty bound to fulfil their end of the contract. This could include the exchange of money, the sale of goods and services, and so on. 

Failure to fulfil a contractual obligation according to the contract’s terms is known as a breach of contract, and can be pursued in court if necessary. In these instances, the terms of the contract can be enforced through the legal system, but the aggrieved party can also potentially be awarded damages to cover any losses they’ve incurred. 

Delict

The law of delict, also known as tort, covers a number of different violations or breaches to obligations imposed by law. These obligations are the ones that people can reasonably expect as part of their daily life, such as going to work and living their life free from assault or harm. 

But in instances where these things do occur, there are steps that can be taken under the law, such as receiving reparation and holding the offending party liable for their actions in court. 

Areas of delict can include:

  • physical assault.
  • invasion of privacy.
  • interference with property.
  • fraud.
  • defamation and slander.
  • nuisance and harassment.

Quasi contracts

Quasi contracts, also known as implied contracts or constructive contracts, are agreements created by the court system and imposed by a judge. They are retroactively imposed between two parties – who previously did not have obligations to one another – to correct a situation. This situation typically involves one party unfairly benefitting from another, or acquiring something at the expense or loss of the other, which is known as unjust enrichment.

Quasi delict

While delict occurs due to someone’s intentional actions, quasi delict is the result of unintentional negligence. For example, someone who accidentally injures another person is still responsible for their actions, but this is considered a quasi delict breach of obligation, rather than a delict breach.

What are some of the forms of obligation?

Absolute obligation

Absolute obligations are the unconditional duties required of a person or party. For example, the UK government has an absolute obligation to protect people’s right to life. According to the Equality and Human Rights Commission, this means “that nobody, including the government, can try to end your life. It also means the government should take appropriate measures to safeguard life by making laws to protect you and, in some circumstances, by taking steps to protect you if your life is at risk. Public authorities should also consider your right to life when making decisions that might put you in danger or that affect your life expectancy.”

Contractual obligation

Contractual obligations are the obligations outlined in contractual agreements. Agreeing to a contract, whether the contract is written or verbal, means that people are duty bound to comply with the terms and obligations stated in the contract.

Express obligation

Express obligations are obligations that are expressly stated, whether this is through a law, a contract, or so on. The terms are spelled out directly, and no part of the obligation or duty is implied or inferred.

Penal obligation

Penal obligations are the penalties that arise from a breach of obligation. For example, if a person fails to pay a bill on time, in breach of the terms and conditions of a contract they signed, they may have a penal obligation to pay a penalty fee. 

Moral obligation

Moral obligations are those that form from a person’s sense of right and wrong, but there is a lot of overlap between moral obligations and legal obligations. For example, most people’s morals dictate that they have an obligation to safeguard human life, but there is also a legal obligation to do this, too.
