“My First Car!” — But Are You Even Legally Allowed to Own It?
Scroll through social media today and you’ll see countless young people posting:
“Just bought my first car!”
“Finally moved into my apartment!”
It sounds impressive — until you stop and ask a simple question:
“Wait… aren’t you under 18?”
Because here’s the truth: in law, owning something and being able to act to acquire it are two very different things. And this is where the concepts of legal capacity and capacity to act become crucial — especially in contracts, business, property, and even online deals.
1. Legal Capacity: The Right to “Have” Rights
Legal capacity is the most basic level of recognition the law gives a person: the ability to have rights and be subject to duties.
Everyone has legal capacity from the moment they are born.
Examples:
But here’s the catch: having a right does not mean you can exercise it yourself.
2. Capacity to Act: The Power to “Use” Those Rights
This is the step most people misunderstand. Capacity to act means you are legally able to perform valid legal acts — such as signing contracts, selling property, starting a business, or suing someone in court.
And in almost every legal system around the world, you don’t get this ability until you reach a certain age — usually 18 years old.
Before that, any contract you sign can be:
Example:
If a 16-year-old signs a contract to buy a car with their own signature, it might look valid — but legally, it’s not. The dealership usually requires a parent or legal guardian to sign. Without that, the deal could be challenged in court and cancelled.
3. Absolute Incapacity: When You Can’t Act at All
The law also recognizes certain categories of people as absolutely incapable of acting on their own. They cannot sign contracts, make wills, or perform any binding legal act by themselves. These acts must be carried out by their legal representative.
Typical examples include:
If such a person signs a contract alone, it’s usually null and void — not just voidable. That means it has no legal effect from the start.
4. Relative Incapacity: When You Need Someone’s Help
Then there’s a middle category — people who are considered relatively incapable. They can perform some legal acts, but others require the assistance, consent, or co-signature of another person (like a parent, guardian, or curator).
This often includes:
-
Minors close to the age of majority
-
Adults under partial legal restriction
-
People under certain types of legal guardianship
Example:
A 17-year-old might be able to open a savings account with parental consent but cannot sell a house or sign a commercial lease alone.
Why This Matters in Real Life
Here’s the uncomfortable truth behind those Instagram posts:
When a 16-year-old says “my apartment” — the legal owner is almost never them. It’s usually:
-
Their parents, who purchased it.
-
A legal guardian acting on their behalf.
-
A company or trust controlled by adults.
They can be the beneficial owner or future inheritor, but until they reach legal capacity to act, they can’t truly acquire or manage that property independently.
Pro Insight:
Brands, real estate agents, and online platforms must also check capacity to act before signing contracts — otherwise, the agreement could collapse later if one party was legally incapable when they signed.
Legal Exceptions for Minors’ Capacity
Here are some of the ways a minor can gain more capacity or have special rights in certain laws:
-
Marriage / Emancipation by Marriage
In some jurisdictions, when a minor is legally married, they become “emancipated” (or partially so) and may gain capacity to act like an adult in certain legal areas. The law effectively grants them more autonomy. Council of Europe+2max-eup2012.mpipriv.de+2
-
Statutory Exceptions (Specific Laws for Minors ≥ a certain age)
Some laws allow minors over a certain age (often 16 or 17) to enter into contracts for specific purposes — such as employment contracts, educational contracts, necessity goods, or certain “ordinary affairs” that are appropriate for their age. Stanford Law School+2www3.jmc.lk+2
-
Emancipation / Independent Status
A minor who is “emancipated” — either through statute, marriage, or sometimes by court order — may be given legal capacity to act more like an adult. Emancipation typically means the minor is self-supporting or has been granted adult‐like rights. ebnet.co.za+2FES Library+2
-
Contracts for Necessities
Even if a minor generally lacks capacity, contracts for “necessaries” (things required for living given their status: food, clothing, shelter, basic education) are often valid. The minor might be liable for reasonable value of those items. Lawyers N Jurists+2FGCU Ruby+2
-
Legal Provisions of Specific Civil Codes
In some civil law countries, minors older than a certain age are allowed to do legal acts “that are usual for someone their age, and not requiring large obligations.” For example, buying everyday items, managing small income, etc. Stanford Law School+2Council of Europe+2
How These Exceptions Relate to “I Bought My First Car/Home” Posts
Understanding these exceptions shows why claims like “I bought a car/home under 18” could be misleading or risky. Some points:
-
Even if a minor marries or is “emancipated,” big contracts (like buying a car or house) usually require more formal legal capacity: signature, proof of ability to pay, registration. Many jurisdictions will still require guardians or co-signers.
-
If the contract imposes significant obligations (loan payments, insurance, maintenance), courts often scrutinize whether the minor had consent, whether the signature is voidable, and whether the contract was for the minor’s benefit or a necessity.
-
Sometimes “having the car” or “owning the home” in social media means the minor is nominally titled, but legally the contract may be signed by parents, the payment responsibility may rest with them, or registration done in the name of someone adult. The minor may not have the full legal control.
