In the state of New Jersey, what is a reasonable amount time to settle an estate that was left with a will?

The estate must be settled within 9 months of the date of death.  There really isn't any "normal" time and  is very dependent on the state of the decedent's financial affairs.  I have settled estates of several million dollars within the 9 month period because the decedent was very organized, but yet its taken me 2 years to settle and estate with nothing in it because the decedent was a hoarder and it took forever to track things down.  The 9 month range is a good start because that is the tax filing requirement.
