Quick answer: Vessels are registered through the National Registry of Ships, with a technical review approved by the MOPT Directorate of Navigation and Security (or the relevant Capitanía de Puerto) beforehand. Aircraft use Costa Rica’s TI registry under the civil-aviation authority (DGAC). Both are technical, nationality- and structure-sensitive processes, and several specifics are best confirmed with a maritime or aviation attorney rather than assumed — we flag those below rather than guess.
Registering a vessel
All boats must be registered through the National Registry of Ships, under the Costa Rican naval-registry regulations. The sequence matters: the technical review of the vessel must be completed and approved by the MOPT Directorate of Navigation and Security, or the corresponding Capitanía de Puerto, before the registration procedures at the National Registry. Whether to flag locally or keep a foreign registry is a decision that interacts with tax, crewing, insurance and where the vessel operates — a maritime-attorney question, not a rule of thumb.
Vessel steps
- ☐ Decide flag: Costa Rican registration vs retaining a foreign registry.
- ☐ Complete the technical review (MOPT Navigation and Security / Capitanía de Puerto).
- ☐ Register through the National Registry of Ships.
- ☐ Address crewing and any charter licensing separately (charter for vessels 24m+ runs through an ICT permit).
Registering an aircraft
Costa Rica’s civil-aircraft prefix is TI, and registration falls under the DGAC. Owners broadly choose between placing an aircraft on the TI registry or retaining a foreign registration such as US N — a decision that affects airworthiness oversight, crew licensing, permitted operations and import treatment. We were unable to verify some of the specific procedural and duty details to a publishable standard, so treat this as the shape of the process and confirm the particulars in writing.

Aircraft steps (general shape)
- ☐ Decide registry: TI vs retaining a foreign registration, with an aviation attorney.
- ☐ Confirm nationality/entity requirements and any import or temporary-importation treatment.
- ☐ Complete airworthiness and documentation requirements for the chosen registry.
- ☐ Address hangarage, maintenance approvals and operating authorisations.
The honest caveat
Both registrations are technical and fact-specific, and the aircraft side in particular has details we would not state without a live official confirmation. Engage a specialist — a maritime attorney for vessels, an aviation attorney for aircraft — and obtain the current requirements in writing for your specific asset. For the ownership-cost context, our asset guides cover the carrying-cost picture.
The flag decision, for both vessels and aircraft
The first and most consequential choice for either asset is whether to register locally or retain a foreign registry, and it is rarely a simple one. For a vessel, the decision interacts with tax treatment, crewing and certification requirements, insurance, and where you actually intend to operate; many international owners keep a foreign registry and berth in Costa Rica, using the ICT charter permit route only if they intend to charter (available for vessels 24 metres and above). For an aircraft, placing it on the TI registry versus keeping a foreign registration such as US N affects airworthiness oversight, crew licensing, permitted operations and import treatment.
Neither decision should be made on a rule of thumb, because the right answer is genuinely fact-specific to how you will use the asset. A vessel that mostly cruises internationally has different considerations from one based permanently in Costa Rican waters; an aircraft flown privately by its owner differs from one used commercially. This is squarely a specialist question — a maritime attorney for a vessel, an aviation attorney for an aircraft — and getting it right at the outset avoids expensive restructuring later.
Why we flag rather than guess on the aircraft specifics
We want to be explicit about the limits of what we can responsibly state. The vessel path — technical review by MOPT Navigation and Security or the relevant Capitanía de Puerto, then registration through the National Registry of Ships — is well established. On the aircraft side, several procedural and duty specifics for TI registration versus a foreign registry could not be verified to a publishable standard, and we will not substitute plausible-sounding figures from other jurisdictions, because the cost of being wrong on aircraft import treatment is high.
So treat the aircraft section as the shape of the process, not a definitive procedure, and obtain the current requirements in writing from the DGAC and an aviation attorney for your specific airframe before committing. The same discipline that protects a property buyer — verify against the primary authority, do not rely on hearsay — applies doubly to a technical, high-value asset registration where the rules are specialised and change.
Engage the specialist before you commit
For an asset of this value and technical complexity, the order of operations is: specialist advice first, commitment second. A maritime attorney for a vessel or an aviation attorney for an aircraft will map the flag decision, the registration path, and the tax and import treatment to how you actually intend to use the asset — before you ship, buy or register anything. Getting this wrong is expensive to unwind, and several of the specifics (especially on aircraft) are ones we deliberately flag for live confirmation rather than state from memory.
Frequently asked
Do I have to register my boat in Costa Rica?
Vessels operating here register through the National Registry of Ships, but many international owners retain a foreign registry and berth locally. The choice interacts with tax, crewing and operations — take maritime-legal advice.
What is the Costa Rica aircraft prefix?
TI. Registration is under the DGAC. Owners choose between TI registration and keeping a foreign registry such as US N, based on operations, oversight and duty treatment.
Why are some details flagged for verification?
Because the procedural and duty specifics — especially for aircraft — could not be confirmed on a live official source, and we will not guess. Confirm them with a specialist for your asset.
Does registering here help with residency?
Not by itself — investor residency is most commonly satisfied through real estate titled in your name. Asset registration is a separate matter.
Should I flag locally or keep a foreign registry?
It depends on tax, crewing, insurance and how you use the asset. Many owners keep a foreign registry and operate here. Take maritime or aviation legal advice rather than a rule of thumb.
Why are the aircraft details less specific?
Because some TI-registration procedural and duty specifics could not be confirmed on a live official source, and we will not guess on high-value, technical rules. Confirm them with the DGAC and an aviation attorney.
Who should I talk to first?
A maritime attorney for a vessel or an aviation attorney for an aircraft, before you ship, buy or register. The flag and registration decision should be mapped to your actual use first.
Can these assets support my residency?
Not directly — investor residency is most commonly satisfied through real estate titled in your name. Asset registration is a separate matter.
