There is no such thing, in Indonesian law, as a 'nominee' system. That idea was invented by realtors, and some others, to sell property. The persons name on the title to any Hak Milik land in Indonesia must be an Indonesian National...end of story.
The side agreements/contracts can be disputed in law but the title to the land is NOT in dispute. It
belongs to the person whose name is on the Sertipikat Tanda Bukti Hak....heirs and successors.
I have two of such Sertipikats in my possession and neither my name, nor my wife, is on any one of them...they are owned by close family members, who are Indonesian nationals, and we simply
trust that our agreements will prevail. If either wish to renege there is very little, in law, we can do.
I've argued this point so many times with expats but it's difficult to argue logic to those inclined to believe an agreement/contract can supersede Constitutional Law in Indonesia....it may be argued in other countries with more mature legal opinion...but Indonesia...good luck!
Bali Discovery had a very good article on this subject in 2007. I commend another read as it is as relevant today...probably more so because of value increase...than then.
