I live in a semi-attached house (attached to another house on one side only). The backyard fence that splits the house is falling apart. I want to know how do I find out if it belongs to them or me, or shared? I noticed that the backside of the fence is facing me, they see the face of the fence. Could this be the determining factor? Do you know of other signs I should look for to determine ownership? I looked all over the deed and it does not say anything about the fence.
