After reading the following article by Andy Ho, I believe that there is a place for champerty [legal dict.][Wikipedia]
in Singapore... (I u'stand that this form of charging does not separate
legal fees from damages sought: it is all just one lump sum and the
lawyer takes cut of 1/3 of damages won) however, if this form of
charging is used, then it must be clearly declared to the court before
any hearing (along with the damages sought)- each side should also lay
clear one's legal costs and the case proceed either by mutual agreement
on legal costs (looser pays the bill)- or else get a government order
that the case would be heard and the government determines the eventual
award and if necessary-legal cost (fixed or by champerty to each party
as the case may be).
