We just completed a survey of Three Rivers Market on Broadway. There was a question about tree ownership. Tree ownership questions are always interesting. Unless a tree is wholly located on one property, the tree is owned jointly (in Tennessee). Ownership of a boundary-line tree — and thus responsibility for the tree — is shared by percentage. Percentage of ownership is not a particularly easy thing to determine. Trees are irregularly shaped and impossible to locate with absolute precision. As there is usually a money or liability issue involved, the percentage of ownership in a tree is an important question. Strive to hire a surveyor who understands these complexities.
