1. Written, signed agreement. The terms of the compromise must be set forth in an agreement in writing that must be executed by all competent persons and parents or legal guardians who have both actual custody and legal responsibility for a minor child acting for any minor child who has beneficial interests or claims that will or may be affected by the compromise. Execution is not required by any person whose identity cannot be ascertained or whose whereabouts are unknown and cannot reasonably be ascertained.

2. Submission to court for approval. Any interested person, including the personal representative or a trustee, then may submit the agreement to the court for its approval and for execution by the personal representative, the trustee of every affected testamentary trust and other fiduciaries and representatives.

3. Hearing and order. After notice to all interested persons or their representatives, including the personal representative of the estate and all affected trustees of trusts, the court, if it finds that the contest or controversy is in good faith and that the effect of the agreement upon the interests of persons represented by fiduciaries or other representatives is just and reasonable, shall make an order approving the agreement and directing all fiduciaries subject to its jurisdiction to execute the agreement. Minor children represented only by their parents are bound only if their parents join with other competent persons in execution of the compromise. Upon the making of the order and the execution of the agreement, all further disposition of the estate must be in accordance with the terms of the agreement.
