The land is worth less every year nobody can touch it.
INHERITED LAND
A father dies leaving a plot and six children. The certificate stays in his name, because transferring it means every heir signing at the same time in the same room, and one of them lives in Kalimantan.
The certificate is in his name. One signature moves the land, and he is the only person who ever needed to be found.
On his death the plot passes to all six equally. Nothing is registered, because registering it needs all six in one room on one day.
Two of the six pass away. Their shares split among their own children, who never met the grandfather's notary and have no copy of anything.
Marriages, a divorce, and one heir who has moved abroad. Every one of them must consent, and three of them have never met.
Nobody refused. The number of people who must agree simply grew faster than anyone could assemble them.
Ten years pass. Two heirs have died and their children are now parties. A six-way conversation has become a nineteen-way one.
It cannot be sold, cannot be pledged, and cannot be divided. Not because anyone objects, but because there is no document saying who holds what portion.
