Can an easement be removed from my property's title if nobody has used it in decades?

Not automatically, and this is one of the most common misunderstandings in this area. An easement isn't extinguished simply because it hasn't been used for years or even decades. Mere non-use, no matter how long, generally isn't enough on its own to wipe out a validly created and registered easement. What's actually required is abandonment, which needs clear evidence that the party who benefits from the easement intended to give up the right permanently, not just evidence that they haven't gotten around to using it.

This distinction matters a lot in practice. A property owner who assumes an old, unused right-of-way or utility easement has simply "expired" with time can be surprised to find it's still fully valid and enforceable on title, sometimes decades after anyone last used it. Evidence of true abandonment tends to involve something more affirmative, such as statements or conduct clearly showing the holder gave up the right, not just years of inactivity.

If you're dealing with an old easement you believe is no longer needed, the safer path is a formal, documented, and registered release from the party who benefits from it, rather than assuming long non-use has already done the job on its own.
