1. If no compensation is provided by the will, or the personal representative renounces all claims thereto, fees must be allowed upon the whole amount of the estate which has been accounted for, less liens and encumbrances, as follows:
(a) For the first $15,000, at the rate of 4 percent.
(b) For the next $85,000, at the rate of 3 percent.
(c) For all above $100,000, at the rate of 2 percent.
2. The same fees must be allowed to the personal representative if there is no will.
3. If there are two or more personal representatives, the compensation must be apportioned among them by the court according to the services actually rendered by each.
4. In addition to the fees described in subsection 1, the court may allow such fees as it deems just and reasonable if the fees authorized pursuant to subsection 1 are not sufficient to reasonably compensate the personal representative.
