TS,
Depends on your income and the kind of expenses that you agree
to have for your kids like :- school fees, tuition fees, swimming
class, piano class, going to the zoo, etc.
As Xcert had mentioned, the expenses should be borned by both
parents. Unless for some reasons your ex-wife can't work.
Anyway you should discuss this with your lawyer. He/she is
suppose to advice you on the amount especially if the lawyer is
veteran in divorce cases.
just to add on a bit...how much maintenance is also related to
the care and control of the kids...
and to go into that...is like opening a big can of worms....
if U are really interested in looking at the previous
judgements...

Its not cheap...Charges for time-based access is S$31.50 for the
first hour and S$6.50 for every subsequent hour purchased (prices
are subject to Singapore GST)....but ur lawyer fee is already
not cheap liao...this amt would be comparatively small.
