Agrarian Law and Land Possession in Guanacaste
Family land without title, usucapion, boundaries that exist in memory rather than on a plano, and the agrarian courts that hear them.
Why agrarian is a jurisdiction of its own
Costa Rica treats farmland differently from other property, and it gives it its own courts. Agrarian matters are heard by agrarian judges under the Codigo Procesal Agrario, Ley 9609, not by the ordinary civil courts, and the difference is more than administrative. Agrarian law starts from the idea that land which is worked has a claim on the law that land merely held does not. Possession, use and the family that lives on the land carry weight here that they would not carry in a civil file.
For Guanacaste and the Nicoya Peninsula that matters enormously, because a large share of the land in this province has been held for generations by people who farm it and have never had a registered title to it. Nicoya is the oldest canton in the country and the one these cases come from most.
Land held without paper
It is common here for a family to have worked the same land for forty or fifty years, to have fenced it, planted it, built on it and buried people on it, and to hold nothing in the Registro Nacional that says so. Nothing goes wrong with that arrangement until something does. A sale falls through because the buyer cannot get financing without a folio real. A relative sells a piece to an outsider. A neighbour moves a fence. A bank will not lend against it. Somebody dies and the children discover there was never anything to inherit on paper.
Possession is not nothing in Costa Rican law. It is the starting point for two different claims, and which one applies depends on whether anyone else already holds a registered title.
Informacion posesoria: turning possession into title
Where the land has never been registered to anyone, the route is an informacion posesoria under Ley 139. What it asks the court to do is recognise that you have possessed the land long enough, and in the right way, to be declared its owner and given a registered title.
The possession has to be quiet, public, peaceful, uninterrupted and exercised as an owner, for ten years or more. Possession can be added together across successive possessors where the chain is properly documented, which is how a claim built on a grandparent’s occupation is often made.
What the file needs, in practice:
- A registered plano catastrado showing the area, the boundaries and the measurements
- Three witnesses with no interest in the outcome, named in the petition
- Institutional certifications on land use and on whether the parcel touches a protected area or forest reserve
- Notice to the neighbours on every boundary, and to the public institutions with an interest
- A valuation of the parcel
- A sworn declaration covering liens and any succession behind the possession
Some land simply cannot be claimed this way, whatever the years of occupation: the maritime zone, land forming part of the natural patrimony of the state, and protected areas established before the claim. Discovering that at the end of the process is an expensive way to learn it, which is why the certifications are the first thing we pull and not the last.
Usucapion: when somebody else holds the title
Where the land is registered to another person, the claim is usucapion rather than informacion posesoria, and it is a contested lawsuit rather than a filing. You are asking the court to move a registered title, and the registered owner will be served and will be heard.
These are the hardest land cases in the province and the ones most often abandoned halfway. They turn on evidence of possession over decades, from people who are elderly, about events nobody wrote down. Photographs, receipts for materials, tax and municipal records, testimony from neighbours, the location of buildings and fences and planting: it is built out of fragments. It is also the only route available when the title says somebody else and the truth on the ground says you.
Boundaries: the plano against the fence
A fence is not a boundary. The registered survey is. In Guanacaste the two disagree often, and the disagreement can amount to hundreds or thousands of square metres, because much of this land was measured a long time ago, some of it from landmarks that no longer exist.
Boundary work starts with the planos on both sides and a survey on the ground before it ever becomes a claim. Sometimes the answer is that the fence is in the wrong place and the cheapest thing anyone can do is move it. Sometimes the plano itself is defective and the correction is registral rather than judicial. When it does go to court, the file that wins is the one that walked the land first.
Family land and the succession nobody opened
The most common agrarian file in this office is not a stranger taking land. It is relatives. A grandparent dies without a will and without anyone opening the sucesion. Twenty years later the land is occupied by one branch of the family, claimed by another, and registered to a person who died in 1986. Some heirs have sold rights they may not have had. Others have been on the land their whole lives and have nothing in writing.
These files are resolvable, and they are worse the longer they wait, because the witnesses who remember who worked what are the generation that is dying. Where a settlement among the family is possible we will push for it. Where it is not, the case goes to the agrarian court, and it matters that it is put together properly the first time.
INDER land and the conditions attached to it
Land allocated by the state through INDER, and by the IDA before it, comes with restrictions: on selling, on dividing, on mortgaging, and on who may hold it, for a defined period. Parcels are nonetheless sold informally, transferred by private document, and built on by people who were never the allottee. The buyer usually finds out when they try to register something. Before you buy anything with an agrarian history, the question to ask is not only who is on it now, but where the parcel came from.
Where these cases are heard
Nicoya has its own courts and hears a large share of the peninsula’s agrarian work, including Nosara and Samara. Matters from the northern cantons run through Liberia, and the central coast through Santa Cruz. The office is in Playas del Coco and we appear in all three.

Common questions about land and possession
We have worked this land for forty years and have no title. Can we get one?
Often, yes. Where the parcel was never registered to anyone, an informacion posesoria under Ley 139 asks the court to recognise your possession and issue a title. It needs ten years or more of quiet, public, peaceful and uninterrupted possession as owner, a registered plano, three disinterested witnesses and certifications that the land is not excluded. The first step is checking whether the parcel is claimable at all.
What is the difference between informacion posesoria and usucapion?
Whether anyone else already holds the title. If the land is unregistered, it is an informacion posesoria. If the registry names another owner, it is usucapion, which is a contested lawsuit against that person and a considerably harder road.
Can any land be claimed through possession?
No. The maritime zone, land forming part of the natural patrimony of the state, and protected areas established before the claim are all outside it, no matter how long the occupation. That is checked at the start of a file, not at the end.
The land is registered to a relative who died in the eighties. What now?
A sucesion has to be opened before anything else can move, however late it is. Until it is, the registered owner is a dead person and nobody can transfer, mortgage or cleanly divide the land. Late sucesiones are ordinary work and they are the unlock for most family land files.
My neighbour moved the fence. Is that a court case?
Not necessarily, and it is worth finding out before filing. We start with both planos and a survey on the ground. Sometimes the fence is simply wrong and moving it ends the matter. Sometimes the plano is defective and the fix is registral. A claim is the answer when neither of those resolves it.
How long do these cases take?
Longer than anyone wants. An uncontested informacion posesoria moves at the pace of the certifications, the notices and the court. A contested usucapion is measured in years. We will give you an honest range for your file once we have seen the plano and the registry position, and we will tell you when a claim is not worth bringing.
