Kan. Stat. § 59-1504
Whenever a decedent by will makes a provision for the compensation of his or her executor, that shall be taken as such executor's full compensation, unless the executor files a written instrument, renouncing all claim to the compensation provided for in the will. Whenever any person named in a will or codicil defends it, or prosecutes any proceedings in good faith and with just cause, for the purpose of having it admitted to probate, whether successful or not, or if any person successfully opposes the probate of any will or codicil, such person shall be allowed out of the estate his or her necessary expenses and disbursements in such proceedings, together with such compensation for such person's services and those of his or her attorneys as shall be just and proper.
Any heir at law or beneficiary under a will who, in good faith and for good cause, successfully prosecutes or defends any other action for the benefit of the ultimate recipients of the estate may be allowed his or her necessary expenses, in the discretion of the court, including a reasonable attorney's fee.
