A gestor handles your paperwork, a lawyer handles legal decisions and appeals, and a tax advisor reads your whole tax position. Expatronus helps you compare all three. Updated October 2026.
This guide is for anyone planning a move to Spain who has been told to "just get a gestor" by one person and "you need a lawyer" by another. By the end you will know what each profession does, where a tax advisor fits, and which question tells you who to call first.
Gestor or lawyer: the short answer
Most moves need a mix. The useful question is not which profession is better. It is whether the next step on your list is a routine filing or a decision with consequences.
What a gestor does
In practice, gestores are the people who know the counters, the forms and the order things go in. For people moving to Spain that usually means:
- Applying for or renewing paperwork that is mostly forms and supporting documents, such as the NIE (your foreigner identification number) or registration at the town hall (empadronamiento).
- Filing recurring tax and social security paperwork once you are set up, including the filings that come with registering as self employed (autónomo).
- Handling vehicle, property and business registrations that are largely administrative.
- Acting for you before an office, so you do not have to attend every appointment yourself.
Their limit follows from the same statute. Where the question is a legal one (which route fits your situation, how to answer a refusal, how to argue a contested point), the work moves to a lawyer.
What an immigration lawyer does
That last part is where the two professions separate most clearly. If an application is denied, the options that follow (a reconsideration request to the same office, or a challenge before the administrative courts) are legal steps with their own rules. Specialised immigration practices describe exactly this as the point where you want a lawyer rather than a general administrative service, and a gestoría itself will usually say the same.
- Choosing between routes when more than one could fit your case.
- A case with a complication, such as a gap in your records, a previous refusal, or a family member on a different status.
- Responding to a request for more documents or to a refusal.
- Anything that could end in court.
Where the tax advisor fits
Many Spanish firms operate as a combined gestoría and asesoría, so one office can do both. If you work with a firm like that, ask who in the firm actually answers planning questions, and who simply submits the forms.
Whatever the title on the door says, ask what the person is registered or qualified as.
Who handles which part of your move
The list below is a map, not a ruling. Your own case decides, and the professional you speak to will tell you where it differs.
- Getting an NIE: often a gestor, or a lawyer if it comes bundled with a residence application.
- Registering at the town hall (empadronamiento): usually something you or a gestor can do. A lawyer is rarely needed.
- Choosing a residence route (digital nomad, non lucrative, work, family): a lawyer first, because the choice itself is the legal question.
- Submitting the application once the route is chosen: a lawyer, or a gestor working from the lawyer's plan.
- Responding to a refusal or a request for more evidence: a lawyer.
- Registering as autónomo and ongoing filings: a gestor, with a tax advisor if your income is mixed.
- Your first Spanish tax return and any special regime: a tax advisor first, then a gestor to file if the situation is simple.
- Buying or renting a home: a lawyer for contract review, a gestor for registrations, a notary for the deed.
Who should you hire first
Start with the decision, not the paperwork. If you do not yet know which route or which tax position you are choosing, speak to a lawyer or a tax advisor before you pay anyone to fill in forms. A perfectly filed application for the wrong route is the most expensive kind of tidy.
If you already have a clear plan (your route is chosen, your documents are collected, you need someone to put it through the system), a gestor is built for that.
What to ask before you hire either one
- What exactly is included, and what would count as extra work?
- Who will actually handle my file, and who do I speak to if they are away?
- Will you act for me before the administration, and what authorisation do you need from me?
- If my application is refused, is that covered, or do I need someone else?
- What is your professional registration number, and with which college or bar?
- Have you handled cases like mine, with my nationality and my route?
- Is the scope and the fee structure in writing before I pay?
Good professionals answer these without hesitation. A vague answer on scope is usually a sign of how the work will feel later.
Common mistakes
- Hiring a gestor to decide something that is a legal question, then discovering the choice was already made by the form.
- Hiring a lawyer for pure paperwork and paying for judgement you did not need.
- Paying a tax advisor for planning after the return is filed, when the planning window has closed.
- Assuming one office covers everything because the sign says so. Check who in the office handles your part.
- Hiring on a message from a stranger in a forum instead of asking for a registration number.
Frequently asked questions
Can a gestor handle my residency application?
Many gestorías submit residence paperwork for clients whose route is already decided and whose case is straightforward. Whether yours is straightforward is a legal judgement, so ask the gestor to say in writing what they will and will not take on.
Do I need a lawyer for the NIE?
Not always. The NIE is an administrative procedure and gestores handle it regularly. If it is part of a larger residence application, the lawyer working on that application often handles it as part of the file.
Do I need both a gestor and a tax advisor as an expat?
It depends on how complicated your income is. A single employment contract is a different conversation from income in several countries or a business of your own. Ask the advisor which of the two roles your case needs.
Who should I hire first when moving to Spain?
Hire for the next decision, not the next form. If you still have to choose a route or a tax position, start with a lawyer or tax advisor. If the plan is set, a gestor can carry it through the system.
Can a gestor represent me if my application is refused?
A gestor acts for you before administrative bodies, but arguing a refusal is a legal task. Ask any gestor in advance what happens to your file if the answer is no, and who would take it on.
Is a gestor cheaper than a lawyer?
Fee structures vary by firm, city and scope, so a general statement would mislead. Compare what is included, not only the headline price.
