Article 25

1. If the parties, regardless of their domicile, have agreed that a court or the courts of a Member State are to have jurisdiction to settle any disputes which have arisen or which may arise in connection with a particular legal relationship, that court or those courts shall have jurisdiction, unless the agreement is null and void as to its substantive validity under the law of that Member State. Such jurisdiction shall be exclusive unless the parties have agreed otherwise. The agreement conferring jurisdiction shall be either:
(a) in writing or evidenced in writing;
(b) in a form which accords with practices which the parties have established between themselves; or
(c) in international trade or commerce, in a form which accords with a usage of which the parties are or ought to have been aware and which in such trade or commerce is widely known to, and regularly observed by, parties to contracts of the type involved in the particular trade or commerce concerned.
 

2. Any communication by electronic means which provides a durable record of the agreement shall be equivalent to ‘writing’.

3. The court or courts of a Member State on which a trust instrument has conferred jurisdiction shall have exclusive jurisdiction in any proceedings brought against a settlor, trustee or beneficiary, if relations between those persons or their rights or obligations under the trust are involved.

4. Agreements or provisions of a trust instrument conferring jurisdiction shall have no legal force if they are contrary to Articles 15, 19 or 23, or if the courts whose jurisdiction they purport to exclude have exclusive jurisdiction by virtue of Article 24.

5. An agreement conferring jurisdiction which forms part of a contract shall be treated as an agreement independent of the other terms of the contract.
The validity of the agreement conferring jurisdiction cannot be contested solely on the ground that the contract is not valid.
