Access easement of driveway

I own property in Oklahoma, my property line ends at the sidewalk and the city owns from the sidewalk to the center of the street. A driveway was installed by the homeowner 70 years ago to give access from the surface street to my adjacent property acrossed the unimproved section of "city property". I assume some type of access easement was granted by the city for homeowners to build driveways (not everyone on the street has cement). This section of my driveway beared the name of a now famous person's signuture that was removed by the "famous person" without my permission or the city's and filled back in with dry cement. My question is who owns the improvement (driveway).

Without knowing the full details and reviewing the documents it is impossible to say. However, based on what you have shared here my best guess would be that you own it. The easement should have passed when you purchased the property. It sounds like you really need a lawyer to get to the bottom of this. You might get a referral by going to the WLD main page for a lawyer in your area. Hope it gets resolved properly. AJJ
