TLDR: Puerto Rico’s courts are seeing a steady rise in contract litigation, driven by a 2020 overhaul of the island’s Civil Code and a wave of new investment deals tied to tax incentive programs. The disputes are testing how much weight judges give to good faith, fairness, and the letter of a contract when the two don’t line up.
A Legal System Working Through Growing Pains
Puerto Rico runs on a civil law tradition, inherited from Spain and layered with over a century of U.S. federal influence. That mix makes contract disputes here different from what you’d see in a typical state court on the mainland. Judges aren’t just checking whether the paperwork was signed correctly. They’re weighing concepts like good faith and proportionality that don’t always show up in common law contract analysis.
Recent rulings out of the island’s courts have put that difference on full display. Local attorneys say they’re fielding more contract-related inquiries than they have in years, and much of it traces back to two things happening at once: a rewritten Civil Code and a surge of new business activity.
Why Contract Disputes Are Piling Up on the Island
It’s not one single event causing the spike. It’s a combination of legal reform and economic activity colliding at the same time.
The 2020 Civil Code Overhaul
In 2020, Puerto Rico replaced its 1930 Civil Code, a document that had governed contracts, property, and family law on the island for nine decades. The update modernized language, clarified rules around obligations, and gave judges more explicit tools to address contracts that go sideways after signing. That last part matters. Courts now have clearer statutory footing to revisit agreements when circumstances shift dramatically after the ink dries, something the old code addressed only loosely through case law.
For businesses used to operating under the prior framework, that shift changes the calculus. A contract clause that would have been enforced without much debate a decade ago might now draw a harder look from a judge applying the newer standards.
Act 60 and the New Wave of Investment Contracts
At the same time, Puerto Rico’s tax incentive program, known as Act 60, has pulled in a steady stream of mainland investors, remote businesses, and individuals relocating for the tax benefits. Each of those arrivals brings contracts: leases, service agreements, investment partnerships, employment deals.
More contracts, written quickly and sometimes by parties less familiar with Puerto Rico’s civil law framework, tend to produce more disputes. Attorneys on the island describe a pattern where mainland-style contracts, drafted with common law assumptions, run into civil law doctrines they weren’t built to handle.
How Puerto Rico’s Civil Law Tradition Shapes These Rulings
This is where things get interesting for anyone used to U.S. contract law outside the island.
Good Faith, Lesión, and the Limits of “a Deal’s a Deal”
Under Puerto Rico’s Civil Code, contracts carry an implied obligation of good faith that runs through formation, performance, and even termination. Courts can also apply the doctrine of lesión, which allows a contract to be challenged if one party got a deal so lopsided it offends basic fairness, something most common law states don’t recognize in anything like the same form.
That doesn’t mean judges are rewriting bad deals left and right. The bar for invoking these doctrines is high, and courts still generally hold parties to what they signed. But the legal door is open in ways it simply isn’t in most U.S. jurisdictions, and that’s shaping how disputes get litigated and settled on the island.
What Businesses and Residents Should Take From This
If you’re doing business in Puerto Rico, whether you’re a longtime resident or a newer Act 60 arrival, a few things are worth keeping in mind.
Contracts drafted using mainland templates don’t always translate cleanly. Clauses that limit liability, cap damages, or lock in terms regardless of changed circumstances can run into pushback that wouldn’t happen in a common law court. Getting a contract reviewed by someone familiar with Puerto Rico’s civil law framework, rather than just adapting a mainland template, tends to save headaches later.
And if a dispute does end up in court, the standard playbook from a common law jurisdiction won’t fully apply. Arguments that lean purely on contract language, without addressing good faith or fairness, may land differently in front of a Puerto Rico judge than they would elsewhere.
What Comes Next
Expect the volume of contract litigation to keep climbing for a while yet. The Civil Code reform is still relatively new, which means courts are actively building out case law interpreting its provisions, and that process tends to generate more filings as attorneys test where the new lines actually sit.
Combine that with continued investment inflow under Act 60, and Puerto Rico’s courts are likely to keep hearing cases that sit at the intersection of civil law tradition and mainland business practice. For anyone entering a contract on the island, that’s reason enough to get local counsel involved early, rather than after a dispute lands in court.
