How to choose a financial adviser in Spain
A practical due-diligence checklist for checking permissions, cross-border expertise, fees, products and conflicts before taking advice.

Finding someone who works with expatriates is not the same as finding the right regulated professional. Tax compliance, investment advice, pension advice, legal work and estate planning are different services. A strong adviser will define the work they can perform, identify the other specialists required and explain how the advice fits your residence, assets and future plans.
Define the problem before choosing the person
Write down the decision you need to make. Examples include preparing a Spanish return, reviewing investments held abroad, taking pension benefits, planning a property sale, investing a cash sum or coordinating an estate. Add your nationality, tax residence, asset countries, expected moves and deadline.
This prevents a general sales conversation from replacing the actual task. If several services are required, ask whether the firm provides them itself or coordinates independent specialists. The person giving investment advice should not imply that their authorisation automatically covers tax returns, foreign pensions or legal drafting.
Check the exact legal entity and permissions
Ask for the firm's full legal name, trading name, registration number, registered address and the name of the individual adviser. Then check the relevant official register independently. For investment services in Spain, the CNMV explains which bodies are authorised and warns that registration does not mean every firm can provide every service. Match the permission to the proposed activity.
If work is provided through an entity in another country, check that country's regulator too and ask how the firm is permitted to serve a resident of Spain. Do not rely on a logo, professional title or registration number copied into marketing material. Use contact details obtained from the official register where possible.
Test genuine cross-border experience
Ask how often the adviser works with people who share your combination of residence, nationality and assets. Request an explanation of which jurisdictions are included and excluded from the engagement. A useful answer will identify where Spanish treatment differs from the country in which an account, pension or product began.
Ask who will deal with foreign tax, pensions or legal questions and how assumptions will be reconciled. If the firm uses an external specialist, understand whether that specialist advises you directly, advises the firm or simply provides general technical support.
Make every cost visible
Request initial and ongoing fees in both percentage and cash terms. Include planning fees, advice charges, platform and custody costs, fund or product charges, trading, foreign exchange, exit penalties, performance fees and taxes. Ask whether the adviser or an associated business receives commission, a referral payment or any other benefit.
Compare the cost of the recommended action with retaining or modifying the existing arrangement. A proposal to transfer, surrender or consolidate should show the tax, fees, lost guarantees and consumer protections as well as the benefits. Ask for an estimate over several years, not only the first-year charge.
Understand products, custody and access
Ask whether the adviser can consider the whole market or uses a restricted product list. Establish who legally holds the assets, where money is sent, which institution issues the product and how you access statements. Never send funds to a personal account or an unrelated company.
Check what happens if the adviser leaves, the firm fails, you complain or you move country. Ask which compensation or dispute-resolution arrangements apply and whether they cover the actual entity and service. Cross-border structures can make these protections less straightforward than the marketing suggests.
Look for a disciplined advice process
Before recommending a product, the adviser should gather enough information about household income, spending, tax residence, assets, debts, investment experience, risk, losses you could bear, time horizon and objectives. For pension work, the review should also cover guarantees, dependant benefits and secure income.
The recommendation should be written, understandable and specific to your circumstances. It should state key assumptions, alternatives considered, costs, tax dependencies, risks and matters outside scope. There should be time to question it without pressure.
Recognise warning signs
Pause if someone makes unsolicited contact, creates urgency, promises high or guaranteed returns, recommends one solution before collecting facts, dismisses tax advice as unnecessary, hides costs in product documents or asks you to sign blank or incomplete forms. Be equally cautious where the adviser will not identify the legal entity, regulator, custodian or complaint route.
A free review is not automatically independent. The business may be paid only if you transfer or invest. That incentive should be disclosed and considered alongside the recommendation.
Prepare for the first meeting
Bring a one-page summary of household members, residence history, financial objectives and likely moves. Add recent returns, income, pensions, investments, properties, debts, insurance and estate documents. Redact unnecessary account and identity details until a secure client process is established.
Use the first meeting to agree scope, responsibilities, evidence, deadline, deliverables and fees. A good outcome is a written action plan—even when the correct recommendation is to keep an existing arrangement. Continue to verify permissions and suitability rather than treating an introduction or expatriate specialism as a guarantee.
Common questions
- How do I check an investment adviser in Spain?
- Obtain the exact legal entity and proposed service, then verify both in the relevant CNMV register. If another jurisdiction is involved, check its regulator and how the service may be offered to a Spanish resident.
- Is an adviser independent if the first meeting is free?
- Not necessarily. Ask how the firm and individual are paid, including advice fees, commissions, referral payments and benefits from associated products or providers.
- Can one adviser handle tax, pensions and investments?
- A firm may coordinate them, but different activities can require different qualifications and permissions. Ask who is accountable for each part and what falls outside scope.
- What should a written recommendation include?
- It should explain objectives, assumptions, alternatives, tax dependencies, risks, all material costs, relevant protections and why the action is suitable for your circumstances.
