Leaves are opposite, pinnately compound with 3 - 5 leaflets. Leaf is 6-8" long, with 2-3" long leaflets. Leaflets are not symmetrical, in fact if you try to hold them together removing the space between the leaflets they look like a simple leaved maple. Lateral leaflets have a larger tooth or lobe on the base edge while the terminal leaflet is larger and symmetrical with lobes of equal sizes.
This is a newer more popular variegated cultivar 'Flamingo' with a reddish cast to the new growth in the spring.
Look at the opposite, pinnately compound leaves and its location, not likely planted.
