Q1: Who is eligible for CPF Housing Top-Up Grant?
A1: A flat owner who has purchased his flat with CPF Housing Grant for Singles is eligible for the Top-Up Grant if:

(a) he subsequently marries a Singapore Citizen (SC) or Singapore Permanent Resident (SPR) who is a first-timer, or another SC who is also a Singles Grant recipient on or after 1 Aug 04; or

(b) his non-citizen spouse or child obtains citizenship or SPR Status and the marriage between the singles grant recipient and his non-citizen spouse is on or after 8 Mar 2005; or

(c) an SC/SPR child is born to him and his wife (whom he married on or after 8 Mar 2005).

The new household must meets all the prevailing eligibility conditions under the CPF Housing Grant Scheme for Family at the point of application for the Top-Up Grant


Q3: When can I apply for the Top-Up Grant including Enhanced CPF Housing Grant (if applicable)?
A3: The married couple must submit their application for the Top-Up Grant within 6 months from:

(a) the date of registration of their marriage; or

(b) the non-citizen spouse/child obtaining citizenship / SPR Status; or

(c) the birth of their SC/SPR child.

应该是最开始拿single grant,配偶拿PR后可以申请top up grant，这个数额就是SC/SPR house hold跟non-citizen spouse scheme的single grant之间的差额， SPR配偶换公民或者生一个公民孩子，可以再申请citizen top up grant
