This discussion clarifies whether a beneficiary can mutate only a portion of a property received through a Will, especially if another part is occupied by someone else. It's explained that while a beneficiary can mutate their share, obtaining a probate of the Will from the court is generally required to legally confirm their entitlement before the mutation process can begin. Attempting to mutate without this legal confirmation can lead to disputes, and the revenue department might require the property to be clearly demarcated.
