Artikel 4

1. The following shall be registered in a Contracting State:
(a) Formal wills declared to a notary, a public authority or any person authorised by the law of that State to record them, as well as other wills deposited with an authority or a person authorised by law to accept such deposit, with a formal act of deposit having been established;
(b) Holographic wills which have been deposited with a notary, a public authority or any person authorised by the law of that State to accept them, without a formal act of deposit having been established, subject to that law permitting such deposit. The testator may oppose registration if the said law does not prohibit such opposition.
2. Withdrawals, revocations and other modifications of the wills registered according to this Article shall also be registered if they are established in a form which would make registration compulsory according to the preceding paragraph.
