The primary Legislation is s.9 :
9. A marriage solemnized in Singapore or elsewhere between persons
either of whom is below the age of 18 years shall be void unless
the solemnization of the marriage was authorised by a special
marriage licence granted by the Minister under section 21.
and s.21
Special marriage licence
21. —(1) The Minister, upon proof being made to him by statutory
declaration that there is no lawful impediment to the proposed
marriage, and upon his being satisfied that the necessary consent,
if any, to the marriage has been obtained, or that the consent has
been dispensed with or given under section 13 may, if he thinks
fit, dispense with the giving of notice and with the issue of a
marriage licence, and may grant a special marriage licence in the
prescribed form authorising the solemnization of a marriage between
the parties named in that licence.
(2) The Minister may, in his discretion, grant a special marriage
licence under this section authorising the solemnization of a
marriage although any party to the marriage is below the age of 18
years.
(3) If the marriage authorised by a special marriage licence under
this section is not solemnized within one month from the date of
the licence, the licence shall become void.
(4) The Minister may delegate his powers under this section to any
person, subject to such conditions as he may think fit to
impose.
Theoradically the minister will grant the marriage licence if the
parents consent and the there is no lawful impediment .
However practically the minister is unlikely to grant the marriage
permit as minors , ie under 21 probably are not really sure what
they want and the minister wants to preserve the sanctity of
marriage.
