Due Diligence in Costa Rica: The Title Study You Can't Skip

I once watched a lovely couple nearly buy a hillside lot in the Nicoya Peninsula that came with a surprise: an easement giving a neighbor the legal right to drive straight across the middle of it, to a piece of land behind. The seller wasn't hiding it, exactly. It was right there in the Registro Nacional for anyone who bothered to look. They just hadn't looked yet. The title study caught it a week before closing. That's the whole reason this step exists.

Due diligence is the least glamorous part of buying in Costa Rica and the single most important. It's the difference between owning a clean piece of paradise and inheriting somebody else's problem. Here's what a proper one actually checks.

The title study at the Registro Nacional

The heart of it is the title study—your attorney pulling the property's full record from the national registry (Registro Nacional). The good news for buyers here is that Costa Rica's registry is public, centralized and surprisingly transparent; a competent attorney can read a property's whole life story from it. What they're confirming:

Ownership: that the person selling is the actual registered owner, with the legal right to sell—not a relative, not a lapsed partner, not one of four heirs who never agreed to anything.
Liens and mortgages: that no unpaid mortgage, loan or judgment is attached to the property. In Costa Rica, encumbrances generally follow the land, not the person—so if you buy it, you can buy the debt with it.
Easements (servidumbres): rights-of-way, utility easements, access for a landlocked neighbor—exactly the trap my couple almost stepped in. Some are harmless; some gut the value or privacy of a lot.
Liens for unpaid taxes or fees: outstanding property tax, municipal charges, or HOA dues that could become yours.
Annotations: pending legal actions or notes flagging a dispute over the property.

The survey: plano catastrado

Every registered property should have a recorded survey map, the plano catastrado, filed with the National Cadastre. Your attorney and, ideally, a surveyor (topógrafo) confirm that the plano matches reality: that the boundaries on the map correspond to the fences, walls and features on the ground, that the stated area is accurate, and that the plano's registry number ties correctly to the title.

In rural Guanacaste this matters more than people think. I've seen a plano that was decades old, a fence line that had “drifted” over the years, and a genuine, honest disagreement about where one farm ended and the next began. Better to sort that out with a surveyor before closing than with a machete-carrying neighbor after.

The water letter: carta de agua

If I could tattoo one phrase on every buyer coming to this coast, it's this: confirm the water. A gorgeous lot with no legal water source is a gorgeous problem. Deals in Guanacaste live and die on the carta de agua—a letter from the local water authority (the ASADA, or AyA) confirming there's an available water connection, or an approved right to one, for that specific property.

Guanacaste is beautiful and it is dry. Many rural areas run on community ASADA systems that periodically hit their capacity and stop issuing new connections ('no hay pajas de agua'). A lot without water rights can't get a building permit, which means you can't build, which means you paid a premium for a very expensive picnic spot. If the property runs on a well instead, due diligence shifts to confirming the well is legal and registered. Either way—verify it in writing before you close. I've talked more than one client out of a “bargain” lot for exactly this reason, and I've never regretted it.

The other checks that round it out

A thorough due diligence period—usually 30 to 60 days written into the option agreement—also covers:

Property tax standing: confirming the municipal tax and any luxury tax are paid current.
The selling corporation, if any: if the property is held in an S.A. or S.R.L. and you're buying the shares, the company itself gets vetted—its debts, its standing, its books become yours.
Permits and zoning: that existing construction was permitted, and that local zoning (plan regulador) allows what you intend to do.
Utilities and access: legal, physical road access to the property—not just a neighbor's goodwill.

Do not skip this to save money or time

The whole title study, survey review and water check costs a fraction of a percent of the purchase price. I've watched buyers try to trim it to close faster or save a few hundred dollars, and it is, without exaggeration, the worst false economy in this business. The registry is transparent precisely so that this is knowable in advance. Choosing not to know is a decision you make once and regret for years.

How long does due diligence take in Costa Rica?

Typically 30 to 60 days, written into the option-to-purchase agreement as a contingency period. Straightforward titled properties can move faster; anything with a corporation, an old survey, or a water question needs the full runway. Don't let a seller rush you below what your attorney says they need.

Can I do the title study myself?

You can look up a property in the public registry yourself, and it's a fine sanity check. But reading it correctly—spotting a subtle easement, an encumbrance that survives the sale, a mismatch between plano and title—takes a Costa Rican attorney who does this daily. This is not the place to save money by going it alone.

What happens if I skip due diligence?

You inherit whatever's attached to the property: unpaid mortgages, tax liens, easements, boundary disputes, or a lot you legally can't build on for lack of water. Once you're the registered owner, those become your problem, not the seller's. There's no undo button in the registry.

The bottom line

Costa Rica's registry is transparent and the checks are well understood—title study, plano catastrado, carta de agua, tax standing, corporate vetting. Done right by a competent attorney, due diligence turns a leap of faith into an informed decision. It's the step I'll never let a client short-change. This article is general guidance from twenty years on the ground, not legal advice—your own Costa Rican attorney or notary runs the actual study.
