Health insurance when you have no fixed residence

The friction point in an otherwise clean structure

People who have arranged their affairs to be tax-resident nowhere tend to have done it deliberately and well. A passport from one country, a company in another, banking in a third, and physical presence rotated so that no single jurisdiction can claim them. The structure works until it meets an insurance application, which opens by asking for a country of residence and, more often than not, a full residential address in it. The honest answer is that there is not one, and that answer does not fit the form.

This is not a small inconvenience to be worked around with a convenient address. It is the point where two systems collide: a life designed to have no fixed residence, and an insurance market that is built, by law, to require one. Understanding why the requirement exists is the first step to satisfying it without misrepresenting anything, because the wrong move here is the kind that stays hidden until a claim, and then costs you the claim.

Why insurers insist on a country of residence

It is tempting to read the residence question as bureaucratic habit. It is not. It is downstream of insurance law. Under the European framework that governs non-life insurance, the risk on a policy is located at the policyholder's habitual residence, and that location decides which country's authorisation the insurer needs, which regulator and conduct rules apply, which premium taxes are due, and whether any compulsory-insurance rules bite. An insurer cannot simply ignore where you live, because where you live determines whether it is even licensed to cover you.

Residence also drives the price. International medical premiums are rated on a named set of factors, and country of residence sits alongside age and area of cover as one of them. The cost of care where you habitually are is part of the calculation. So the residence field is doing two jobs at once, legal and actuarial, and neither of them is optional from the insurer's side.

That is why the answer to "can I just leave it blank or put an accommodation address" is usually no. The insurer needs a real answer to know it is allowed to sell you the policy and to price it. Which raises the harder question of what a real answer is when you genuinely do not have a settled base.

How the market defines residence

The definitions are more concrete than you might expect. International medical policies typically define a principal country of residence as the country where you live for more than six months of the year. Home country is defined separately, usually as a country for which you hold a passport or which is your principal country of residence. Applications commonly ask for all of these at once: home country, nationality, principal country of residence, and a mandatory full address in that country of residence.

For a perpetual traveller, the majority-of-year test is precisely the thing that does not resolve. If you spend a few months each in several countries by design, no single one is where you live for more than half the year. You have not failed to answer the question; the question assumes a fact pattern you have deliberately avoided. That mismatch is the root of the whole problem, and it is why generic advice to "just pick one" is dangerous rather than helpful.

The honest part: many plans will decline you

Here is the truth the comparison sites tend to skip. A serious portion of the international medical market requires residence proof during underwriting, and a genuinely residence-less applicant does not clear it. Some products go further and bar particular countries as a country of residence outright, regardless of the applicant's nationality, and a handful of high-cost markets are excluded from the standard area of cover. The premium end of the market, the plans built around high limits and concierge-style service, is not where the residence-less case is easiest. If anything it is more demanding on exactly this point.

What does work sits in a narrower band. Certain renewable plans and cashless-card products are structured to accept buyers without a settled country of residence, and a small number of others do the same. These tend to be mid-market rather than premium, and the acceptance is conditional on the application being completed correctly. So the realistic picture is not "there is a perfect residence-less policy for wealthy nomads" and not "you are uninsurable". It is that a specific set of products will cover you, on specific terms, if the paperwork is honest and precise. Getting matched to that set, rather than being declined by the rest, is most of the value.

The field that decides your claim

If there is one line on the application to get right, it is country of ordinary residence. This is the field an adjuster returns to when a large claim lands, sometimes years into the policy, and asks for a home address to process the payout. If what was declared at application does not match how you have actually lived, the insurer has grounds to treat the risk as misrepresented, and a misrepresented risk is a declined claim.

This is what makes a wrong answer here worse than having no policy at all. An uninsured traveller who receives a hospital bill knows where they stand. A traveller who paid premiums for three years against a residence they invented, and then has the claim refused for that reason, has paid for nothing and still owes the bill. The convenient answer, an address you can produce but do not really live at, is the one most likely to produce that outcome.

The correct approach is to answer truthfully within the market that accepts a residence-less profile, rather than to force a false residence onto a policy that would otherwise decline you. That is a matching problem, not a wording trick, and it is worth solving before you buy rather than at the moment you claim.

Continuity when your residency does change

Residence-less today does not mean residence-less forever. Many in this position eventually take a second residence or a golden visa, and the insurance has to keep up. International plans generally expect you to notify a change of residence, and such a change can alter your cover or your premium even when you move to another country inside the same area of cover. A policy that was valid where you were may not be valid where you go.

For someone whose whole point is to keep moving, this is the metric that matters more than the first-year price. The useful question is not what the policy costs this year. It is whether it still pays out cleanly after the second and third change of base, and whether the insurer will follow you or quietly restrict cover at the next renewal.

Insuring a family that is not in one place

The residence problem compounds with dependants. On a single policy, residence is captured per person, so an application can record a spouse and children living in different countries. But the area of cover is chosen once for the whole policy, and insurers set their own rules on how far apart members may live and still share one contract. The structural capacity to record different residences does not guarantee that any given insurer will underwrite a household genuinely spread across borders on one plan.

For a family that is deliberately multi-country, this is worth confirming rather than assuming. It is workable for many and a real constraint for some, and the difference turns on the specific insurer's rules, not on a general market principle.
