The concept of an easement is that another person has the right to use your property in some narrowly defined way. The easement is typically granted though a deed or similar instrument. Generally speaking, the issue of who has to maintain the property affected by the easement is determined by who generally uses it. For example, if your neighbor used the easement exclusively and you never used it, the burden on him might be greater. You will need to exercise an ordinary standard of care, however,
The best way perhaps to protect yourself is through a contract with your neighbor in which your neighbor agrees to indemnify and defend you against any liability arising from the act or omission of your neighbor, and you agree to indemnify your neighbor for any injury caused by your act or omission. If only your neighbor makes the promise and the neighbor already owns the easement, the agreement may be deemed to lack consideration and therefore be invalid.
In sum, you could have liability for an injury caused by your act or omission, but you may be able to clearly protect yourself against the acts or omissions of your neighbor. Though you may have some protection in property law, I would suggest a clear indemnification agreement as well.
