A floating easement describes a right of way or similar servitude whose precise route or location is not fixed on creation, but is intended to be capable of later definition on the ground. In practice, it usually arises where land is to be developed or subdivided and the dominant owner needs rights over the servient land, but the eventual road, access or service corridor layout is not yet determined.In England and Wales and Northern Ireland, “floating easement” is not a statutory term but a descriptive label used in case law and practice. The courts have traditionally been cautious about upholding easements that lack sufficient certainty of route or extent, but will recognise rights that are initially flexible, provided they are capable of being made certain by subsequent construction, plan, or agreed use.In Scotland, the analogous concept falls within servitudes; again, uncertainty of route or extent can threaten validity, but flexibility is sometimes tolerated where later specification is contemplated. In Ireland, the expression is also descriptive rather than legislative, with similar concerns about certainty.Floating easements are significant in drafting development agreements, transfers, leases and wayleave arrangements, where future-proofing access and service rights is essential.
