Nine concordats are listed for Malta from the two decades since 1985. Four of these agreements are marked "non occorre la ratifica", meaning they were not ratified by Parliament, but simply “sealed and approved” by the Maltese Foreign Minister on behalf of the government of Malta.
The Maltese concordat texts are available online on the Vatican website in two different places: under Agreements of the Holy See and the Concordats of John Paul II (under i concordati). Because not all were ratified, only the date of signing is given below.
