In Singapore, if there is no executor because, for example:
No executor is appointed in the will
Executors appointed are incapable of carrying out instructions in the will
Executor doesn’t want to be an executor
Executors are dead
The court will choose one or more person(s) (called administrator(s)) most suitable to manage the deceased’s assets, and Letters of Administration will be granted instead.
You can apply for a Grant of Letters of Administration if you are:
A beneficiary (person entitled to a share of the estate)
At least 21 years old
Have a sound mind (doesn’t lack mental capacity)
