Glossary

Cross-border terms, explained clearly

Short explanations of the terms that appear across banking, mobility, tax, wealth, property and insurance.

Residency & mobility

Apostille
A certificate, under an international convention, that confirms the origin of a public document so another country is more willing to accept it. Not every country participates, and not every document qualifies.
Centre of vital interests
A tie-breaker used in some tax treaties when two countries both treat you as resident. It looks at where your personal and economic life is closer. The outcome is fact-specific.
Learn more → Double-tax treaties
Certified translation
A translation that a qualified person has attested, sometimes required before a foreign document will be accepted by a bank, court or registry.
Citizenship
Membership of a country, usually with a passport and political rights. It is acquired by birth, descent or a later process, and it is not the same as living there.
Learn more → Citizenship
Day-count test
A rule that looks at how many days you spend in a country. Days are often only one part of a residence test. A personal count is a record, not a determination.
Learn more → Tax residency
Dependant
A person, often a spouse or child, whose immigration, tax or insurance position is tied to someone else. Whether they may join you, or are covered, is a question for that visa, policy or tax rule.
Digital nomad visa
An immigration route aimed at people who work remotely for an employer or clients elsewhere. It is permission to be in that country. Tax, payroll and banking remain separate questions.
Learn more → Digital nomads
Domicile
A legal idea, used differently in different countries, about where a person belongs for certain tax or succession questions. It is not a visa, and it is not always the same as tax residence.
Dual citizenship
Holding citizenship of more than one country at the same time. Whether that is allowed depends on the laws of each country involved.
Learn more → Citizenship
Habitual residence
Where a person ordinarily lives, looking at the reality of their life rather than a single document. Courts and tax rules may use the phrase in different ways.
Immigration residence
Permission to live in a country under its immigration rules. A visa or residence permit can exist without making you tax resident, and the reverse can also be true.
Learn more → Residency
Local registration
Signing on with a municipality, police or other local authority after you arrive. It can be separate from both the visa and the tax registration.
Naturalisation
The process of becoming a citizen of a country you were not a citizen of at birth. Residence, language and other conditions, where they exist, are set locally.
Learn more → Citizenship
Permanent residence
A longer-term right to reside, short of citizenship. What it allows, and how it can be lost, depends on the country that granted it.
Learn more → Residency
Residence permit
A document or status that allows a person to reside in a country for a stated purpose and period. The conditions, including work and family, sit in that permission.
Learn more → Residency
Tax residence
The status used to determine which country may tax you as a resident. It is usually based on local rules such as days, home, family and work, and it is not the same as immigration residence.
Learn more → Tax residency
Visa
Permission to enter or stay for a particular purpose, such as work, study, family or a visit. It does not, by itself, decide tax, banking or healthcare.
Learn more → Visas
Work permit
Permission to take employment, sometimes issued separately from the right to reside. An employer, a sponsor or the individual may have to hold it, depending on the route.

Banking & payments

AML
Anti-money laundering: the rules and checks aimed at stopping criminal money moving through the financial system. They are why a large or unusual payment attracts questions.
Beneficial owner
The person who ultimately owns or controls an asset or a company, even if the name on the account is different.
Learn more → Company structuring
Beneficiary
The person or account that is meant to receive a payment. The name on the instruction should match the account the bank holds.
Correspondent bank
A bank that holds an account for another bank so payments can move between countries or currencies. It can appear on a transfer even when you did not choose it.
Exchange-rate markup
An amount added to a reference rate before you are shown a customer rate. A transfer with a low fee can still be expensive once the markup is included.
Expat banking
Everyday banking for someone who lives outside their home country: which accounts stay open, which can be opened, and which documents are asked for.
Learn more → Expat banking
FX spread
The gap between the rate a provider buys a currency at and the rate it sells it at. Part of what you pay can sit in that gap rather than in a visible fee.
Learn more → FX cost comparison
IBAN
An international format for a bank account number, used so a payment can be addressed to the right account. Having an IBAN does not tell you the fees or the exchange rate.
Intermediary bank fee
A charge taken by a bank in the middle of an international payment. It is not always shown in the quote you accepted.
International bank account
An account used when the customer, the income or the payments are not all in one country. What the bank will open depends on its own criteria.
Learn more → International bank accounts
KYC
Know your customer: the identity and background checks a financial firm runs before it will open or keep an account. The documents vary by firm and by country.
Local account details
Account numbers that let someone pay you as if you held a domestic account in that country. They may be provided by your own bank or by a partner.
Mid-market rate
A reference exchange rate between the market buy and sell prices. The customer rate offered by a bank or provider may include a spread or markup.
Learn more → FX cost comparison
Multi-currency account
An account that can hold balances in more than one currency, so money can be received or kept without being converted at once.
Learn more → Multi-currency accounts
Payment rail
The system a payment travels on, such as a local scheme or an international message network. The rail can change the speed, the information required and the fees.
Settlement
The moment a payment or a currency exchange is actually completed, as distinct from the moment you instructed it.
Source of funds
The explanation, with documents, of where a particular payment came from — salary, a house sale, a dividend, a gift. It is about that money, not your whole life.
Source of wealth
The broader explanation of how you accumulated what you have, as distinct from the origin of one transfer. Banks ask for it more often when balances or payments are large.
SWIFT / BIC
A code that identifies a bank on the SWIFT messaging network. It helps route a payment. It is not, by itself, proof that the payment will be cheap or instant.
Transfer limit
A cap a provider places on how much you can send in a period, or in one payment. The figure, where one exists, is in that provider’s terms. This glossary states none.
UBO
Ultimate beneficial owner. Another way of naming the person at the end of an ownership chain. Firms ask for this when a company is the customer.

Wealth & investing

Advisory management
An arrangement in which the manager recommends, and you decide. The line between this and discretionary management is in the contract, not the brochure.
Asset allocation
How a portfolio is divided among types of investment. It is a design choice. It is not, by itself, a forecast of what you will earn.
Base currency
The currency a portfolio is measured in. A gain in that currency can hide a loss in the currency you spend.
Beneficiary nomination
A form that says who should receive a benefit if you die. It can sit apart from your will, and it should be re-read after a move, a marriage or a separation.
Broker
A firm that arranges deals in investments. Some also hold the assets. Some only execute. The label does not tell you whether advice is included.
Currency risk
The chance that a move in exchange rates changes what an investment or a payment is worth in the currency you use.
Learn more → Cross-border investment
Custodian
The firm that safeguards the investments, as distinct from the person who advises on them. In a cross-border account, the custodian’s location can matter for tax reporting and for what happens if a firm fails.
Defined benefit pension
A pension that promises a benefit worked out from salary and service, rather than from an investment pot. Transferring one is a specialist decision.
Learn more → Pensions
Defined contribution pension
A pension built from contributions and investment returns, with no promised income. What you can do with it after you move depends on the scheme and on both countries.
Learn more → Pensions
Discretionary management
An arrangement in which the manager can buy and sell without asking you each time, inside an agreed mandate.
Execution-only
A service that carries out the deals you instruct, without advising you that they are suitable.
Fund domicile
The country whose law the fund is established under. It is not the same as where you live, or where the investments inside the fund are.
Investment currency
The currency a particular holding is priced in. It can differ from both your income and the portfolio’s base currency.
Investment platform
A service that holds and deals in investments for you, often online. What you can buy, and whether the firm will accept your country of residence, are separate questions.
Learn more → Investment platforms
Nominee account
An arrangement in which investments are held in the name of a nominee, for the benefit of the client. You should still be able to see that you are the beneficial owner.
Offshore investment
A loose phrase for an investment held outside the investor’s home country, or in a fund based elsewhere. It is not a tax result, and it is not automatically advantageous.
Learn more → Offshore investing
Pension transfer
Moving pension rights from one scheme to another. Across a border it can have tax and access consequences that are easy to underestimate. It is not a default step of a move.
Learn more → Pensions
Portfolio
The collection of investments held for a person or a family. Currency, wrappers and which country taxes them can matter as much as the list of holdings.
Tax wrapper
A legal structure, such as an ISA or a pension, that changes how the investments inside it are taxed in the country that created the wrapper. Another country may not recognise it.
Learn more → ISAs and moving abroad
Wealth manager
A person or firm that looks after a portfolio, sometimes with advice, sometimes with the authority to decide. The contract should say which.
Learn more → Wealth management

Tax & structuring

Beneficial ownership
The person who enjoys or controls an asset, as distinct from the name on a register. Tax rules and bank checks both use the idea.
Learn more → Company structuring
Beneficiary
A person who may benefit from a trust, a pension or a life policy. The word is used in each of those contracts. The rights are not the same.
Learn more → Trusts
Capital gains
Tax on the profit when an asset is sold or otherwise disposed of. Which country can tax the gain can depend on residence, on where the asset is, and on a treaty.
Learn more → International taxation
Company tax residence
Where a company is treated as resident for tax, which may follow incorporation, management, or both. Incorporating in a country does not, by itself, settle the question.
Learn more → Company structuring
Cost basis
The figure a gain is measured from, often what you paid, sometimes adjusted. A move can raise the question of whether that figure is reset. The answer is local, and it should be documented.
Domicile
In some tax systems, a long-term connecting factor that can affect inheritance tax or overseas income. It is a technical status. A move does not automatically change it.
Double-tax treaty
An agreement between two countries that allocates taxing rights and can reduce the same income being fully taxed twice. Whether it applies depends on the income and on residence.
Learn more → Double-tax treaties
Estate
What a person leaves, and the process of dealing with it. Property, accounts and policies in several countries can make it several estates in practice.
Learn more → Estate planning
Executor
The person named to carry out a will. A different country may not automatically accept an executor appointed at home.
Forced heirship
Rules in some countries that reserve part of an estate for particular relatives, regardless of what a will says. Whether they apply is a local legal question.
Learn more → Estate planning
Foreign tax credit
A way some countries reduce their own tax to reflect tax already paid elsewhere on the same income. The credit, the limit and the paperwork are local.
Management and control
Where the real decisions of a company are taken. Some countries use it, alongside or instead of the place of incorporation, to decide company residence.
Learn more → Company structuring
Permanent establishment
A tax concept that can arise when a business has sufficient activity or presence in another country. Whether one exists is fact-specific and may require professional advice.
Learn more → Company structuring
Probate
The process of proving a will and administering an estate. Assets in another country may need a local process as well.
Learn more → Estate planning
Protector
A person given powers over a trust, such as a say in who the trustees are, without necessarily being a trustee or a beneficiary.
Learn more → Trusts
Settlor
The person who creates a trust and puts assets into it. Their tax position can continue to matter after the trust exists.
Learn more → Trusts
Source-based taxation
Tax charged by the country where income or a gain arises, even if you live somewhere else. Employment, rent and dividends are common examples.
Learn more → International taxation
Succession
How assets, control and decision-making pass when someone dies or steps back. More than one country’s rules can apply to the same family.
Learn more → Succession
Tax residence
The status used to determine which country may tax you as a resident. It is usually based on local rules such as days, home, family and work, and it is not the same as immigration residence.
Learn more → Tax residency
Trust
An arrangement in which trustees hold assets for beneficiaries, under the terms of the trust. Another country may treat it differently, or not recognise it at all.
Learn more → Trusts
Trustee
The person or company that holds and administers trust assets. Where the trustees live and meet can affect how the trust is taxed.
Learn more → Trusts
Withholding tax
Tax taken from a payment before you receive it, often on dividends, interest or royalties crossing a border. A treaty may reduce it. It may not remove tax in your country of residence.
Learn more → Double-tax treaties
Worldwide income
The idea that a country taxes its residents on income wherever it arises. Many residence systems work this way. Whether yours does is a local question.

Property

Beneficial ownership
Who really owns or controls the property when the name on the title is a person, a couple or a company. Lenders, lawyers and tax authorities may all ask.
Learn more → Ownership structures
Community fee
Another name for the shared costs of a development. Arrears, and how decisions are voted, belong in the checks before you buy.
Completion
The point at which the purchase is finished and the price is paid, under that country’s process. It is not always the day you receive the keys.
Completion funds
The money that has to arrive, in the right name and currency, in time to complete. A rate on a website is not those funds.
Learn more → Property finance
Conveyancing
The legal work of transferring a property. The steps, and who must do them, differ by country. A lawyer from home may not be qualified to do them.
Freehold
Ownership of the property and, usually, the land it stands on, for as long as the local law allows. The exact right is the one in that country’s register, not the English word.
Learn more → Buying overseas
Joint ownership
Two or more people holding the property together. How they hold it can change who must sign, and what happens if one of them dies.
Learn more → Ownership structures
Land registry
The public record of ownership in countries that keep one. A search shows who is registered and, often, which debts or restrictions are noted.
Leasehold
The right to use a property for a period of years under a lease. What you are buying is the remaining term and the conditions, not necessarily the building forever.
Learn more → Buying overseas
LTV
Loan to value: the loan as a proportion of the property’s value. Lenders set their own ceilings. This glossary does not state one.
Learn more → Expat mortgages
Non-resident mortgage
A loan secured on a property when the borrower does not live in that country, or does not earn there. Eligibility is the lender’s decision.
Learn more → Expat mortgages
Rebuild value
What it might cost to reinstate a building, as distinct from what the property would sell for. Buildings insurance is often discussed against this figure, not the market price.
Learn more → Property insurance
Rental yield
Rent as a proportion of the price, usually before costs, tax and empty periods. A brochure yield is not a forecast of what you will keep.
Learn more → Property tax
Reservation agreement
A document that takes a property off the market, sometimes in exchange for a payment. It is not always the purchase contract, and the payment is not always refundable.
Service charge
A contribution towards the running of a building or estate, common in apartments. Ask what it covers, and whether special works are being discussed.
Source-of-funds check
The questions a lawyer or a bank asks about where the purchase money came from. Start the papers before the week of completion.
Learn more → Property finance
Title
The legal right you are acquiring, and the record of it. Reading the register, where one exists, matters more than the floor plan in a listing.
Learn more → Buying overseas

Insurance

Annual limit
The ceiling on what the policy will pay in a year, in the currency the contract names. A headline limit can still contain smaller caps.
Area of cover
The countries or regions where the policy applies. A wide description can still exclude places, or cover them only for emergencies.
Learn more → International health insurance
Beneficiary
The person named to receive a payment under a life or other policy. The nomination can sit apart from a will, and a move is a reason to check it is still right.
Learn more → Life insurance
Claim
A request that the insurer pay, judged against the wording. Notification, evidence and a decision are the usual shape. Nothing in a definition predicts the result.
Co-insurance
An arrangement in which you and the insurer each pay a proportion of a covered cost, after any deductible the policy applies.
Co-payment
A share of a cost you pay when you use a benefit, sometimes a fixed amount and sometimes a percentage. It can sit alongside a deductible.
Deductible
An amount you pay towards a claim before the insurer pays. How it is applied — per year, per claim, per person — is in the schedule. No figure is stated here.
Direct billing
An arrangement in which the insurer pays a hospital or repairer, rather than you paying and claiming the money back.
Excess
Another word for the part of a claim you bear yourself. Travel, property and health policies can each use it differently.
Exclusion
Something the policy sets outside cover: a condition, a country, an activity or a use. Two policies with similar headlines can exclude different things.
Inpatient
Treatment that involves admission to hospital, often including surgery and an overnight stay. It is a different benefit from care you receive and then leave.
Medical evacuation
Moving a person to treatment, often to a facility the insurer considers suitable. It is a benefit with conditions. It is not a guarantee that a particular journey will be arranged.
Learn more → International health insurance
Moratorium underwriting
An approach in which recent conditions may sit outside cover for a time described in the policy, and then be reconsidered. The period, if any, is in that contract. This glossary does not state one.
Learn more → How underwriting works
Outpatient
Care that does not require admission: a GP, a specialist, diagnostics, therapy, prescriptions. A plan can cover hospital treatment and still say little about this.
Policyholder
The person or organisation that owns the contract with the insurer. They are not always the person who is insured, and they are not always the beneficiary.
Pre-authorisation
Agreement from the insurer before a treatment or repair goes ahead. Emergencies may be described differently from planned care.
Pre-existing condition
A condition the policy defines by reference to earlier diagnosis, symptoms, treatment or medication. The definition in the contract matters more than a sales summary.
Learn more → Health insurance for expats
Provider network
The hospitals, clinics or repairers the insurer has arrangements with. A large limit is less useful if the place you will actually use is outside it.
Repatriation
Bringing a person home, which in a policy may mean after treatment or, in some wordings, after death. Which country counts as home is in the contract.
Learn more → Travel insurance
Sub-limit
A smaller cap that applies to one benefit, such as outpatient care, baggage or a particular treatment, inside a larger limit.
Underwriting
The process of deciding whether to offer cover and on what terms. It can look at health, occupation, property use or what a business does. The outcome is the insurer’s decision.
Learn more → How underwriting works

Business

API
A connection that lets one system send instructions to another, for example a payment from accounting software. Access to it should be controlled like access to the bank.
Batch payment
Several payments sent together as one instruction. The checks on who approved the file matter as much as the checks on a single transfer.
Beneficial owner
The person who ultimately owns or controls a company, even if the shares are held through another entity. Banks and registries both ask who that person is.
Learn more → Company structuring
Branch
A presence of a company in another country that is not a separate company. Tax and registration can still apply to it.
Director
A person appointed to manage a company. Where they live, and where they take decisions, can matter for banking and for where the company is taxed.
Learn more → Company structuring
Dual approval
A control that requires two people to authorise a payment or a change. It is a common answer to the risk of a single compromised login.
Employer of record
A firm that employs a person locally on behalf of a company based somewhere else, and runs payroll for that employment. It does not, by itself, decide tax or immigration.
Learn more → Employer of record
Holding company
A company whose main role is to own other companies or assets. Where it is managed can matter as much as where it was incorporated.
Key person
Someone whose absence would materially hurt a business. Insurance sometimes sits beside that risk. It does not replace a plan for who decides next.
Learn more → Business insurance
Maker-checker
A version of dual control in which one person prepares a payment and another approves it. The two roles should not be the same person.
Payroll
The process of paying employees and dealing with the deductions that employment requires. A remote team can mean more than one country’s payroll.
Permanent establishment
A tax concept that can arise when a business has enough activity in another country to be taxed there on the profits of that presence. Whether one exists is fact-specific.
Learn more → Company structuring
Professional indemnity
Cover concerned with claims that professional work was wrong, late or incomplete. Client contracts often ask for it. Whether the policy meets the clause is a reading exercise.
Learn more → Business insurance
Registered office
The official address of a company for legal documents. It is not necessarily where the business is run, or where tax residence sits.
Shareholder
An owner of shares in a company. Ownership, control and who benefits can be three different maps of the same firm.
Subsidiary
A company owned or controlled by another. It is a separate legal person. A policy or a bank account of the parent does not automatically include it.
Learn more → Company structuring
Trade finance
Facilities that support buying, selling or shipping goods, such as a letter of credit. They are contracts with their own conditions. This glossary does not describe a particular product.
Treasury
How a company holds, moves and converts its money. It is an operating function, not a product.
Webhook
A message a system sends automatically when something happens, such as a payment arriving. It is a notification, not the payment itself.
Working capital
The money a business uses to operate between being paid and paying others. Currency and timing both sit inside it.
