Disagreement on location of property line for installing fence

[Jacky Johnson]

I'm a homeowner who plans to install a fence on my driveway along my property line to preserve privacy b/c there have been a lot of strangers going in and out of my neighbor's house constantly. I'm concerned. I gave a note to my neighbor (owner of her house) a few days ago that I'm going to start today and any post or rails will be on my side and I will pay the cost of the installation myself. In addition, the neighbor's trash bins have been next to my neighbor's side of the wall adjacent to my driveway. If I completely enclose the driveway with the fence, my neighbor will have to move her trash bins somewhere else b/c there won't be enough space to let those bins to pass through. I started the work today and my neighbor suddenly said I installed the posts past my property line and she will have to ask the county tomorrow to do an assessment about the location of the correct boundary line. I said I wouldn't object. I plan to ask her how long does the process take b/c I'm positive I did not install the posts past my property line (I measured it). What else should I do now and how should I continue to handle this situation?
