Is the fee awarded to the executor of a deceased's estate for his services limited in any way?

Yes! Under the regulations applying to Israeli inheritance law, the court will not normally set a fee that exceeds 3% of the value of the estate . It  will take into account the estate's overall value,the kind of property in it, and the type and scope of work undertaken. The court  has discretion to increase the figure, to up to 4% of the estate, if  exceptional work was involved.
