Ownership stops at the fence

Thai property publishers call this ปัญหาโลกแตกประจำหมู่บ้าน — the village’s unsolvable problem. It is not, as it happens, legally unclear at all.

Your ownership ends at your fence line.

Everything beyond it — the road, the drainage, the footpath — is common property. Inside a housing estate that means it belongs to the estate collectively, managed by the juristic person. Outside one it is a public way. In neither case is it yours, and in neither case do you have a right to park on it.

The lawful place to park is inside your own boundary.

That is the whole legal answer, and almost nobody behaves as though it were true.

The gap this article is actually about

Two boundaries exist and they are not in the same place.

The legal boundary is the fence. It is drawn on a title deed, it does not move, and everybody could look it up.

The felt boundary is หน้าบ้านเรา — the front of our house — and it extends as far as a household has habitually used. It is not written anywhere. It is established entirely by occupation.

Every dispute of this kind is the second boundary meeting somebody else’s version of the second boundary. The first one is not in the argument at all, because both parties are usually unaware of it.

And the question worth asking is not why people park outside. It is why a rule this clear produces no consequences.

Because the offence needs somebody to have been wronged

Here is the mechanism, and it is the finding.

The Land Traffic Act B.E. 2522 (1979) provides, at section 55, that it is an offence to park at a junction, in a marked no-stopping zone, or across the entrance or exit of a building or a driveway.

Read the third of those carefully, because it is the one that gets used.

If somebody parks across your gate, you have a specific, nameable grievance. There is an identifiable victim — you — an identifiable harm, and a provision that fits. You can call the police and something will happen.

Now consider a car parked in the middle of the common road, blocking nobody in particular, narrowing the soi for everybody.

Technically it is on land the driver has no right to occupy. Practically, whose right has been infringed?

Everybody’s. Which in enforcement terms means nobody’s.

There is no complainant, because the injury is distributed. The juristic person can make rules and can levy charges, but it is a body corporate that has to decide to act, against a resident who pays its fees, over a harm no individual member has suffered acutely enough to press.

So the rule is clear, the breach is visible, and the enforcement requires a victim who does not exist.

This archive has repeatedly found obligations attaching to whoever can be identified — article 170’s forged-licence buyer, article 143’s venue, article 146’s traveller. This is the same principle running backwards: a right is enforced only where a rights-holder can be found. Common property has no such person, which is precisely what makes it common and precisely what makes it undefended.

And the car is doing a job

Now the part that explains persistence, because “selfish” does not.

Article 142 of this collection looked at a small Thai market in which people are paid to sit in a queue. Its finding was that presence establishes priority where no allocation system exists. Somebody has to be in the chair, and the chair is worth money precisely because occupying it is the only way to hold the place.

A car parked in front of a house is doing exactly that job.

In a soi with no allocated parking, the space outside your house is unowned and unassigned. The only way to hold it is to occupy it. And the moment you move the car inside, the claim lapses — the space becomes available to the neighbour with three cars, and you will not get it back.

Which makes the behaviour self-reinforcing and entirely rational. The cost of complying is not inconvenience for one evening. It is the permanent loss of a space you have been using for years.

That is why exhortation never works on this, and why it is a genuinely hard problem rather than a moral failing. Nobody defects from an equilibrium unilaterally when defecting costs them the asset.

Why the car is outside in the first place

Four reasons, and only the last is about attitude.

The plot’s parking was sized for the plot, not for the household. Thai housing estates and townhouses are typically built with space for one or two vehicles. Household car ownership has not stayed at one or two.

The front area is frequently in use for something else — storage, a shop, an extension of the living space, a workshop. The car is displaced because the space is occupied.

The soi was never designed to be parked in. Article 164 Nobody built the connections established that Bangkok’s secondary road network was built by landowners to give access to their own plots, under land acquisition and budget constraints that left the connecting network unfinished. Those roads were sized for a car to pass, not for a car to pass a parked car.

And the space outside is free. It costs nothing, it is allocated to nobody, and occupying it is the only way to hold it.

What you can actually do

This is not legal advice and anyone in a live dispute should take some.

Know where your boundary is. It is the fence. The strip outside it is not yours, which also means the neighbour parking there is not trespassing on you — a distinction that resolves a great many arguments before they start.

If a vehicle blocks your gate, that is the enforceable case. Section 55 addresses parking across the entrance or exit of a building or driveway, and there is an identifiable complainant: you.

Inside an estate, the juristic person is the first route, not the police. It manages the common property and sets the internal traffic rules, and a rule that allocates parking is the only thing that actually solves this — because the problem is an absent allocation, not an absent law.

And do not move, block or interfere with somebody else’s vehicle. It converts a parking dispute into something else entirely, with you on the wrong side of it.

Common misconceptions

“The road outside my house is mine.” Ownership ends at the fence. Beyond it is common property or a public way.

“It’s a private estate, so traffic law doesn’t apply.” The internal roads are common property and parking on them is not a right. Section 55 offences can still arise.

“Nobody can do anything about it.” They can when there is an identifiable victim — most obviously, a blocked driveway.

“People do it because they’re inconsiderate.” Some are. But the space is unallocated and occupying it is the only way to hold it, which makes it rational.

“A rule would fix it.” The rule exists. What is missing is an allocation and somebody with standing to enforce it.
