An insurer domiciled in a Contracting State may be sued, either in the courts of that State, or in another Contracting State in the courts for the place where the policy-holder is domiciled, or, if two or more insurers are the defendants, in the courts of the Contracting State where any one of them is domiciled.

An insurer may also, if there is provision for such jurisdiction in the law of the court seised of the matter, be sued in a Contracting State other than that of his domicile in the courts for the place where the agent who acted as intermediary in the making of the contract of insurance has his domicile, provided that this domicile is mentioned in the insurance policy or proposal.

An insurer who is not domiciled in a Contracting State but has a branch or an agency in one of the Contracting States shall, in disputes arising out of the operations of the branch or agency, be deemed to be domiciled in that State.
