"The court is to approach with suspicion the consideration of a will procured and propounded by a person taking a large benefit thereunder, although the will may have been prepared by a solicitor, and though fraud is not pleaded by the person opposing the will and where there was no testamentary incapacity on the part of the testator or the witness."
"It is not the law that in no circumstances can a solicitor or other person who has prepared a will for a testator take a benefit under it. But that fact creates a suspicion that must be removed by the person propounding the will. In all cases the court must be vigilant and jealous. The degree of suspicion will vary with the circumstances of the case. It may be slight and easily dispelled. It may, on the other hand, be so grave that it can hardly be removed."
