Housesitting in Costa Rica

The teeth are real but slower than the story: ownership by occupation (usucapión, Código Civil arts. 853–860) needs TEN years of possession held openly “as the owner” — and Costa Rica's courts even allow it against a duly-registered title, framed as a sanction on an owner who for a decade never appears to defend the property. There is no “one-year” rule and no “Parasite Law.” But possession by permission — a tenant, a borrower, a housesitter — is mere holding that the law says can NEVER ripen into ownership, so a documented sit defeats any claim, and a present sitter denies a third party the continuous, public possession the doctrine needs. The takeaway is the protection, not the panic: an ordinary holiday-empty home is nowhere near a decade of adverse possession.

Under the Maritime-Terrestrial Zone Law (Ley 6043, 1977), a 200-metre strip inland from the high-tide line along both coasts is national public domain. Its first 50 metres — the zona pública — is inalienable: it can never be owned, fenced or occupied, and must stay open to everyone. The remaining 150 metres can only be leased by municipal concession, never owned outright. So “you can't own the beach” is literally true, and stronger than the folklore: you can't privately own any of the 200-metre maritime zone. A sitter may always walk the shore below the house.

The 2017 reform (Ley 9458) made deliberate animal cruelty a genuine prison offence, written into the Penal Code and reaching “whoever” harms an animal, not just its owner. Killing a domestic animal carries three months to two years; cruelty causing lasting harm three months to one year; lesser mistreatment and abandonment draw fines. (Press reports of “up to three years” quote the original draft bill — the enacted ranges are lower, but still custodial.) Deliberate cruelty in Costa Rica can mean jail.

The Wildlife Conservation Law (Ley 7317, reformed by Ley 9106 in 2013) vests wildlife in the national domain: keeping a wild animal without authorisation from the conservation authority (SINAC) is unlawful and fined, and the 2013 reform added sanctions for FEEDING wild animals, which harms them by changing their behaviour and spreading disease. So both halves hold — you can't keep one, and you're not meant to feed them. An injured wild animal goes to a licensed rescue, not a spare room.

Costa Rica runs a territorial tax system (Income Tax Law 7092): only income from a Costa Rican source is taxable, so foreign pensions, overseas rentals and foreign-investment returns are genuinely not taxed, for residents and non-residents alike. The part-true edge: income for work physically performed on Costa Rican soil can be argued to be Costa-Rica-source, so a remote worker invoicing foreign clients while sitting here sits in a recognised grey zone — and the digital-nomad visa's exemption is for foreign-earned income specifically. “Foreign income is never taxed” is the right instinct, not quite an absolute — worth a tax adviser for a long working stay.

A tourist stamp grants temporary stay only — never residency or work rights (Ley 8764). British visitors can be given up to 180 days, but the officer on arrival decides the actual length; since a November 2025 immigration directive (AJ-484-11-2025), some nationalities are given only 30 days. “Perpetual tourism” is tolerated but is not a lawful residency route: overstaying costs US$100 a month and can mean being refused entry later. The 2025 bill to force a 90-day wait between stays (expediente 24854) was rejected, so no waiting period is law — but re-entry stays at the officer's discretion.

Money isn't the test. Across legal systems, what makes an arrangement binding is that two people genuinely agreed to it and meant it to count — not whether cash changed hands or anything was signed, and it can be spoken or shown by conduct rather than written down. (Some systems look for something given on each side — here, James's care for Sarah's keys and a roof; others ask only that the promise was seriously meant. A housesit clears either bar.) So 'no cash, nothing signed' is the wrong line everywhere. The subtler, equally universal catch: a purely social favour can fall short of an intended legal commitment, and even a binding deal is painful to prove once memories differ. Agreeing clear terms up front helps with both, which is the point of agreeing them.

In most systems an agreement can be oral or formed by conduct; a signature and a formal document aren't what make it binding. What's hard about an informal deal isn't its validity — it's proving what was actually agreed once memories differ. Writing the terms down doesn't create the obligation; it records it, so nobody has to argue about it later.
