The Hague Convention,
Hague Convention VII (18 October 1907)
Convention Relating to the Conversion of Merchant Ships into War-Ships
Articles 1 - 12
Entry into Force: 26 January 1910

-------------------------------------------------------------------------
-------
Whereas it is desirable, in view of the incorporation in time of war of merchant
ships in the fighting fleet, to define the conditions subject to which this
operation may be effected;
Whereas, however, the Contracting Powers have been unable to come to an agreement
on the question whether the conversion of a merchant ship into a war-ship
may take place upon the high seas, it is understood that the question of
the place where such conversion is effected remains outside the scope of
this agreement and is in no way affected by the following rules;

Being desirous of concluding a Convention to this effect, have appointed
the following as their Plenipotentiaries:

(Here follow the names of Plenipotentiaries)

Who, after having deposited their full powers, found in good and due form
, have agreed upon the following provisions:

Article 1. A merchant ship converted into a war-ship cannot have the rights
and duties accruing to such vessels unless it is placed under the direct
authority, immediate control, and responsibility of the Power whose flag
it flies.

Art. 2. Merchant ships converted into war-ships must bear the external marks
which distinguish the war-ships of their nationality.

Art. 3. The commander must be in the service of the State and duly commissioned
by the competent authorities. His name must figure on the list of the officers
of the fighting fleet.

Art. 4. The crew must be subject to military discipline.

Art. 5. Every merchant ship converted into a war-ship must observe in its
operations the laws and customs of war.

Art. 6. A belligerent who converts a merchant ship into a war-ship must,
as soon as possible, announce such conversion in the list of war-ships.

Art. 7. The provisions of the present Convention do not apply except between
Contracting Powers, and then only if all the belligerents are Parties to
the Convention.

Art. 8. The present Convention shall be ratified as soon as possible.

The ratifications shall be deposited at The Hague.

The first deposit of ratifications shall be recorded in a proc鑣- verbal
signed by the representatives of the Powers who take part therein and by
the Netherlands Minister for Foreign Affairs.

The subsequent deposits of ratifications shall be made by means of a written
notification, addressed to the Netherlands Government and accompanied by
the instrument of ratification.

A duly certified copy of the proc鑣-verbal relative to the first deposit
of ratifications, of the notifications mentioned in the to preceding paragraph
, as well as of the instruments of ratification, shall be at once sent by
the Netherlands Government, through the diplomatic channel, to the Powers
invited to the Second Peace Conference, as well as to the other Powers which
have adhered to the Convention. In the cases contemplated in the preceding
paragraph the said Government shall at the same time inform them of the
date on which it received the notification.

Art. 9. Non-Signatory Powers may adhere to the present Convention.

The Power which desires to adhere notifies its intention in writing to the
Netherlands Government, forwarding to it the act of adhesion, which shall
be deposited in the archives of the said Government.

That Government shall at once transmit to all the other Powers a duly certified
copy of the notification as well as of the act of adhesion, stating the
date on which it received the notification.

Art. 10. The present Convention shall come into force, in the case of the
Powers which were a party to the first deposit of ratifications, sixty days
after the date of the proc鑣-verbal of this deposit, and, in the case of
the Powers which ratify subsequently or which adhere, sixty days after the
notification of their ratification or of their adhesion has been received
by the Netherlands Government.

Art. 11. In the event of one of the Contracting Powers wishing to denounce
the present Convention, the denunciation shall be notified in writing to
the Netherlands Government, which shall at once communicate a duly certified
copy of the notification to all the other Powers, informing them of the
date on which it was received.

The denunciation shall only have effect in regard to the notifying Power,
and one year after the notification has reached the Netherlands Government
.

Art. 12. A register kept by the Netherlands Ministry for Foreign Affairs
shall give the date of the deposit of ratifications made in virtue of Article
8, paragraphs 3 and 4, as well as the date on which the notifications of
adhesion (Article 9, paragraph 2) or of denunciation (Article 11, paragraph
1) have been received.

Each Contracting Power is entitled to have access to this register and to
be supplied with duly certified extracts from it.

In faith whereof the Plenipotentiaries have appended their signatures to
the present Convention.

Done at The Hague, 18 October 1907, in a single copy, which shall remain
deposited in the archives of the Netherlands Government, and duly certified
copies of which shall be sent, through the diplomatic channel, to the Powers
which have been invited to the Second Peace Conference.
