Legal fiction

Lawyers sometimes use special rules. They act like something is true. This helps things work well.

One rule helps new parents. It says they are the real parents. This happens even if they are not related by blood. This is a kind way to help.

Another rule helps when people die. If two people die at once, the older person is seen as dying first. This helps with rules for money.

Sometimes, courts treat a big company like a person. This lets the company own things. It also lets them sign papers.

These rules can change over time. Some rules are old. Others are new. They help our world run smoothly.

Lawyers sometimes use a special tool called a legal fiction. This happens when the law treats something as true. It might not be literally true in real life. However, this helps the law reach a fair result. Some people call these rules "scaffolding" for a building. This means they help hold things up while the law grows.

One example is child adoption. When a child is adopted, the new parents become the legal parents. This is true even if they are not related by blood. Another rule helps when people die at the same time. If it is impossible to know who died first, the law says the older person died first. This helps with rules for passing on money.

Courts also use these rules in other ways. They might treat a large company like a single person. This lets a company own things or sign papers. Sometimes, a court might treat a piece of property like a person. This is called "in rem" jurisdiction. In the United States, this can lead to funny case names. One case was about "50,000 Cardboard Boxes."

A legal fiction is a special tool used in law. It happens when a court treats something as true to reach a specific goal. Even if a fact is not literally true, the law acts as if it is. This helps the legal system work smoothly in tricky situations. Some people call these fictions "scaffolding" around a building under construction. This means they help support the law while it grows and changes. However, not everyone likes them. A famous critic named Jeremy Bentham said fictions are to law what fraud is to trade.

One way this works is through child adoption. In an adoption, the new parents become the legal parents. They do not have a biological relationship with the child. Yet, the law treats them as the true parents. A new birth certificate is issued to show this change. At the same time, the biological parents become legal strangers to the child. They no longer have legal rights to the child. This process uses a legal fiction to create a new family structure.

History shows many different types of these rules. In old England, lawyers used names like John Doe and Richard Roe. They used these fake names to avoid dangerous trials called "wager of battle." A wager of battle was a duel used to settle land disputes. People used the fake story of Doe and Roe to have a jury trial instead. This helped people avoid risking their lives in combat. Another example is the doctrine of survival in England and Wales. The Law of Property Act 1925 says if two people die at once, the older person died first. This helps rules about who inherits money or land.

Legal fictions also appear in modern rules and big organizations. In the United States, courts sometimes treat a corporation like a person. This is called "legal personhood." It allows a company to own property or sign contracts just like a human. Courts also use "in rem" jurisdiction to deal with property. This treats an object as if it were a person in a court case. This can lead to very funny names in court records. One case title was "United States v. Article Consisting of 50,000 Cardboard Boxes."

Sometimes, the law changes because our knowledge grows. In the Mabo case in Australia, the High Court rejected old rules. Those old rules said Indigenous Australians could not hold land titles. The court realized those ideas were wrong based on new historical knowledge. This shows that legal fictions can be removed when they are no longer fair. Laws also use "constructive" rules to make sure things are enforced. For example, "constructive possession" means you control something even if you are not touching it. These tools help the law stay steady even when life is complicated.

A legal fiction is a specific construct used within a legal system. It occurs when a position is taken to be true to facilitate a certain outcome. This position is not literally true in reality. Courts may employ these fictions, or they may be found within written legislation. They differ from legal presumptions. A presumption assumes a fact is true until someone proves it is not, such as the presumption of legitimacy. While some see them as helpful, others use the term pejoratively. Supporters describe them as "scaffolding around a building under construction."

One common mechanism is seen in child adoption. In this process, adoptive parents become the legal parents of a child. This happens even if there is no biological relationship between them. Once a judgment of adoption is entered, the biological parents become legal strangers to the child. They no longer have legal rights related to that child. A new birth certificate is then issued to reflect this change. This document acts as a legal fiction to establish the new family structure.

Another mechanism is the doctrine of survival. This rule applies when two or more people die in a way that makes the order of death impossible to determine. In England and Wales, the Law of Property Act 1925 provides a solution. It states that the older person is considered to have died first. This rule protects the operation of inheritance laws. For example, if a parent and child die together, a grandchild might inherit from both. This allows the parent to inherit and then immediately bequeath property. Many U.S. states have since replaced this with the Uniform Simultaneous Death Act.

History shows how fictions were used to avoid physical danger. In old English common law, land disputes could lead to a "wager of battle." This was a judicially sanctioned duel where parties risked their lives. To avoid this, lawyers used a procedure called the mixed action in ejectment. They told a fictional tale about characters named John Doe and Richard Roe. They claimed Doe leased land but was ousted by Roe. This allowed a jury to decide the title instead of a duel. This is why those names are still used for anonymous parties today.

Legal fictions have also been used to expand the power of specific courts. In England, the Court of the Exchequer used a fiction to handle more debt cases. Litigants would claim they owed money to the King that they could not pay. This brought the cases under the Exchequer's jurisdiction. Similarly, the Court of King's Bench used the "Bill of Middlesex." This allowed them to claim jurisdiction over cases by alleging a trespass occurred in Middlesex. Once a defendant was in custody, the trespass charge was often dropped for a different claim.

In the United States, the concept of legal personhood is very significant. The Supreme Court has created doctrines that grant corporations rights similar to individuals. This allows a corporation to enter into contracts, own property, or sue others. However, there are notable exceptions to these rights. For instance, corporations do not have the right to proceed in court *in forma pauperis*. This means they must pay normal process fees. They also cannot hold citizenship, which is reserved for natural persons.

Courts also use "constructive" fictions to ensure laws are enforceable. Constructive notice considers a person to have received information if certain procedures, like publication, were followed. Constructive possession means a person controls property even without physical contact. There is also constructive fraud, which involves misrepresenting facts without needing a specific intent to deceive. In civil law, "in rem" jurisdiction treats property as a defendant. This can lead to unusual case titles, such as *United States v. Article Consisting of 50,000 Cardboard Boxes*.

Finally, legal fictions can be changed or removed as society evolves. In the Australian case *Mabo v Queensland*, the High Court rejected old legal authorities. Those authorities had claimed Indigenous Australians could not hold land titles. The court rejected this based on increased historical knowledge. This shows that fictions are not permanent. They rely on tradition and precedent rather than formal law. When social norms or facts change, these legal tools may be updated or discarded to ensure fairness.
