On the ANTS (France Titres) website, each account is individual and linked to a single identity. The platform does not allow creating a profile in the name of a third party using their own credentials. However, the law permits an individual to carry out administrative procedures on behalf of someone else, provided they adhere to a specific framework based on a mandate or power of attorney.
Mandate and Power of Attorney ANTS: What the Legal Framework States
The mechanism is based on civil representation. A representative (the person acting) uses their own ANTS account to carry out a procedure for a principal (the person concerned by the title). The principal does not provide their email address or password: they sign a power of attorney document that authorizes the representative to act on their behalf.

Specifically, the representative logs into their personal space on ants.gouv.fr and selects the “for someone else” option when initiating the procedure. The form then requests the identity information of the principal as well as a copy of the signed mandate. This document must mention the full identity of both parties, the exact nature of the delegated procedure, and the handwritten or electronic signature of the principal.
Several prefectures, including that of Haut-Rhin, remind that any authenticated French citizen can carry out the procedure for a third party provided they supply this mandate. The procedure is the same for a vehicle registration certificate, a driver’s license, or a request related to a registration certificate. Before proceeding, it is useful to know how to create an ANTS account for another person correctly, as even a minor error on the mandate can block the file.

Individual or Authorized Professional Account: Two Distinct Logics
A common misconception is that a second ANTS account must be opened in the name of the relative. The platform prohibits this: one account corresponds to a single natural or legal person. If you create an account with a third party’s email address and your own information (or vice versa), you risk having the file rejected, or even being suspected of identity theft.
For businesses, the logic differs. A “pro” ANTS account can be opened by the legal representative or a designated employee, via ProConnect and the SIRET number of the entity. This account allows for managing the registration procedures for the company’s fleet of vehicles. It is not an account “for a relative” in the sense of an individual, but a delegation governed by corporate law.
The Case of Automotive Professionals
Professionals authorized by the Ministry of the Interior (dealers, approved garages, online service providers) have specific access to the Vehicle Registration System. Going through one of them for a vehicle registration certificate or a change of holder does not require a mandate in the ANTS sense, as their prefectural authorization serves as permission to process the file. This option is often faster for individuals who are not comfortable with digital tools.
FranceConnect Login and Technical Pitfalls to Avoid
Since the redesign of the France Titres portal, several connection methods coexist: the classic ANTS account (username and password received by email), FranceConnect, and FranceIdentité. Each method is linked to the user’s digital identity. When you assist a relative, you must log in with your own credentials, not theirs.
Here are the most common mistakes that lead to a file being blocked:
- Using the principal’s email address to create an account in the name of the representative. The activation link, valid for a limited time, then arrives in an inbox that the representative does not always have access to, delaying validation.
- Forgetting to check the “procedure for a third party” option and filling out the form as if the request concerned the account holder. The administration will reject the file in case of inconsistency between the account identity and that of the actual requester.
- Not attaching the signed mandate or providing an incomplete document (absence of the principal’s ID number, missing signature). The file then goes into “missing document” status, and the processing time extends by several weeks.
An ANTS account inactive for twelve months is automatically deleted. If your relative already had an account but has not used it for a long time, it will need to be recreated, which poses no problem as long as the information matches their real identity.
Vehicle Registration Procedure for a Third Party: The File to Assemble
The request for a registration certificate for a vehicle is the most common procedure carried out via an ANTS mandate. The digital file to be uploaded includes specific documents beyond the mandate itself.
- A double-sided copy of the principal’s identity document (valid national identity card or passport)
- A copy of the representative’s identity document
- The signed mandate, dated and specifying the exact procedure (change of holder, new registration, duplicate)
- The usual supporting documents for the procedure: old registration certificate crossed out, valid technical inspection for a used vehicle, proof of residence of the principal
The mandate must specify the exact procedure, not simply “all administrative procedures.” A formulation that is too broad may be rejected by the processing agent. Field feedback varies on this point: some prefectures accept a generic mandate, while others require a document targeted at the requested operation. Drafting a specific mandate remains the most reliable precaution.
Processing Time and File Tracking
Once the file is submitted online, the representative can track the progress from their own ANTS space. Notifications (validation, request for additional documents, sending of the title) arrive at the email address of the account used, thus that of the representative. Be sure to pass this information on to the principal so they are aware of the progress status.
The procedure is not exceptional from a legal standpoint. Assisting an elderly parent, a spouse who is not familiar with digital tools, or a friend abroad is part of the uses provided by the platform, as long as you stay within the scope of the mandate and never impersonate the title holder requested.
