Often, I will see instances where someone has run a line across a piece of property for purposes of getting electricity, or tapping into a sewer or a water source. So, the answer is yes, you can get prescriptive easements for access to those types of things.
On the other hand, if you are the landowner and your neighbor is trying to utilize a portion of your property, you may want to stop them so that you have unrestricted use of your own property. If you are going to allow them to utilize a portion of your property, you will want to give them an easement on terms that are agreeable to you and that protect your use of your own property.
There are a couple of issues here. If somebody has been utilizing your property, you should either stop them from utilizing it or give them an easement that is recorded. If the easement is not settled and recorded, then when you sell your property, you will need to disclose that somebody is utilizing a portion of your property and may have a claim against that property.
This could cause your buyer to walk away from the deal. On the other hand, if you have a legitimate easement on your property and place a contingency in the documents that the buyers can review the easements and determine whether they want to walk or not, it is less likely to cause you a problem when trying to sell the property.
