Should you give your gestor your login (Cl@ve) or certificate?

Key rules

• Credentials: Your certificate and Cl@ve are personal; anything done with them counts as done by you.
• Alternative: Authorise your gestor through registered representation instead of sharing a login.
• Scope: You choose whether the permission is general, specific or for filing only, and for how long.
• Ending it: Revoke or change the permission in the same register when the work finishes.

Keep your login and certificate to yourself

Do not give your gestor your Cl@ve or your digital certificate. Give them authorised representation instead. They can then do the work in their own name, on your behalf, without your credentials.

Both are personal and cannot be passed to anyone else. You are responsible for keeping them safe and for anything done with them. If a gestor uses your login, the law treats their actions as yours.

What to give your gestor instead

The adviser acts under your permission. This is called apoderamiento. You choose how much they can do. Which route fits depends on the office involved:

• A registered permission (apoderamiento). You register it in the state's electronic register of powers. It can be general, for all procedures, or specific, for named procedures. Any administration can see it.
• Tax. For tax filings, your gestor can act through tax collaboration, which lets them file taxes for you.
• Social Security. Your gestor can act as an authorised RED user, so they handle Social Security matters under their own access.
• Traffic and immigration offices. These also accept representation, either as a written authorisation or as a notarised power. Ask the office which one it wants.

The decision block below helps you choose between these options.

How to register the permission

You can register online or in person.

1. Online: use the register's electronic office with your own certificate or Cl@ve. You use it yourself and never share it.
2. In person: go to an assistance office (Oficina de Asistencia en Materia de Registros) with your ID.
3. Fill in the form. Name your gestor, say what they can do (general, specific or filing only) and for how long.
4. Your gestor may need to accept the permission.
5. After validation you receive proof of registration. Keep it and show it to your gestor.

Some forms belong to a particular office, so check you are using the one for the procedure you need.

When the work ends

You can revoke or change the permission in the same register. Do this when your gestor's job is finished, so no open access remains.

The checklist, documents list and questions below cover the details step by step.

Choosing between options

How can your gestor act for you without your login?

• General or specific apoderamiento: You want one registered permission that any administration can see, for all procedures or only certain ones.

• Tax collaboration: Your gestor only needs to file your taxes with the tax agency.

• Written authorisation or notarised power: The office, such as immigration or traffic, asks for an authorisation or a notarised power.

Never hand over your login. Pick the route for the office your gestor deals with; if several offices are involved, a registered apoderamiento is the broadest option.

Documents you need

• Your digital certificate or Cl@ve access, to register the apoderamiento online. You only use it yourself; you never hand it over.

• Your ID, to register in person at an assistance office (Oficina de Asistencia en Materia de Registros) instead of online.

• The registration form, naming your gestor, what they can do (general, specific or filing only) and for how long.

• The proof of registration you receive after validation. Keep it to show your gestor.

Checklist

• Keep your certificate and Cl@ve to yourself; do not send them to your gestor.

• Choose how to register: online with your certificate or Cl@ve, or in person at an assistance office with your ID.

• Fill in the form naming your gestor, what they can do (general, specific or filing only) and for how long.

• Ask your gestor to accept the permission if the form requires it.

• Revoke or change the permission in the same registry when the work ends.

Frequently asked questions

Can my gestor act for me with Social Security or immigration offices too?

Yes, Social Security has its own authorisation for gestors, called RED. Immigration and traffic offices accept a written authorisation or a notarised power instead.

Who is responsible if my gestor uses my login and something goes wrong?

You are responsible, because actions done with your certificate or Cl@ve are legally treated as yours.

Can I cancel the permission later?

Yes, you can revoke or change an apoderamiento in the same registry where you registered it.

Does my gestor have to accept the permission?

Often yes, because the person you appoint may need to accept before the permission works. Confirm with your gestor after you register.
