For information only. This article is an editorial orientation resource. It does not constitute legal advice. The scope of privileges and immunities depends on your specific accreditation category, your sending state’s implementing legislation, and applicable bilateral agreements. Consult your mission’s legal or administrative office for guidance specific to your situation.
The phrase “diplomatic immunity” is used casually and often inaccurately. In practice, the scope of privileges and immunities a person holds depends on a specific set of determinations (some made by treaty, some by the receiving state, some by the sending mission), and the outcome varies considerably depending on where in the hierarchy you sit.
The treaty sets the framework, not the outcome
The Vienna Convention on Diplomatic Relations (1961) defines four categories of mission staff: diplomatic agents, administrative and technical staff, service staff, and private servants. Each category carries a different scope of privileges and immunities. Diplomatic agents (Article 31) enjoy full immunity from the criminal, civil and administrative jurisdiction of the receiving state. Administrative and technical staff (Article 37.2) enjoy immunity from criminal jurisdiction but their civil and administrative immunity is limited to acts performed in the course of their duties. Service staff (Article 37.3) enjoy immunity only in respect of acts performed in the course of their official duties.
The category you are placed in is not self-selected. It is determined by the function you hold, recorded by your mission in its notification to the receiving state’s ministry of foreign affairs, and confirmed in the identity card or legitimation card issued to you.
The receiving state records and verifies
In France, the MEAE’s Sous-direction des Privilèges et Immunités Diplomatiques et Consulaires records each person’s category. The series of the titre de séjour spécial (CMD/D, CD/D, AT/D, K) reflects that categorisation. The series is not cosmetic: it determines the vehicle registration series you are entitled to, the scope of customs relief available to you, and, critically, the scope of your immunity in any interaction with French authorities.
In Switzerland, the FDFA legitimation card carries a type designation (B, C, or others) that encodes the same information. In Belgium, the D or C card issued by the Protocol Directorate indicates your category.
What the card does not tell you
The identity card confirms your category under the host state’s records. It does not tell you the full scope of your immunities in every situation, because those immunities are determined by the treaty, your category within it, and any bilateral agreements between your sending state and the host state that may extend or, in rare cases, restrict the Vienna Convention baseline.
Family members present an additional layer of complexity. Under Article 37.1 of the 1961 Convention, members of the family of a diplomatic agent forming part of the household enjoy the same privileges and immunities as the diplomatic agent, provided they are not nationals of the receiving state. A spouse who holds the nationality of the host country does not benefit from these privileges, regardless of what the family identity card says.
This last point is one of the most frequently misunderstood. A French-national spouse of a diplomatic agent posted to France holds no diplomatic privileges in France, even if they hold a family-member identity card. The card confirms their relationship to the principal holder; it does not extend the principal’s immunities to them.
The practical takeaway
Before assuming the scope of any privilege or immunity, whether in a traffic stop, a tax query, a contractual dispute, or any other situation where status might be relevant, confirm your category with your mission’s administrative or legal office and understand what that category does and does not cover. The conventions are short documents. Reading the relevant articles takes twenty minutes and removes a great deal of uncertainty.
