The hinge, and it is one fact

Delaware's adverse possession doctrine runs in both directions between an association and its members, and what decides which way is the same in either case: did the record owner ever assert ownership or control?

At Swann Keys, the paper owners never did — not for decades — while the association surfaced the ramps, maintained them, and let members use them. Title moved.

Compare the Stonebridge case decided in February 2026, where townhome owners who had used and improved an adjacent strip of association open space for years lost their adverse possession counterclaim. The reason was that a predecessor's use had been permissive — and, as that court put it, “A use is adverse or hostile if it is inconsistent with the rights of the owner.” Use an association tolerates is not inconsistent with its rights; it is an exercise of them.

The two cases are one doctrine. The association that says nothing loses ground; the association that grants permission keeps it.

What this means for an association's own title gaps

Find them. Compare what the association actually maintains and controls — ramps, piers, walkways, parking, retention ponds, well houses, mailbox clusters, entrance features, the strip behind the clubhouse — against what its recorded deeds and plats actually convey. In Delaware the mismatch is common, because common areas were frequently conveyed by developer deeds prepared decades ago, and because settlements and replats do not always produce conforming instruments. Swann Keys' gap survived a court-approved settlement.

Fix them by agreement if you can. A corrective deed, a boundary-line agreement or a recorded easement from a cooperative neighbour costs a fraction of a quiet-title action. The window for that is before someone discovers a paper claim and puts up a barrier.

Keep evidence of use and of maintenance. The record that won this case was ordinary: who mowed it, who repaired it, who used it, for how long, unchallenged. Minutes, invoices and photographs are what prove a prescriptive period twenty years later.

Do not rely on adverse possession as a plan. It worked here after decades and litigation through two courts. It is a remedy for a problem, not a substitute for a deed.

Where the exposure actually lands

A title gap in a common area is not an abstract problem. Three consequences follow directly.

Maintenance obligation without authority. An association's declaration typically obliges it to maintain the common areas, and its assessments fund that. Spending assessment money on land it does not own is a question a board will eventually be asked.

Insurance. Coverage follows the described premises. An amenity the association does not own may not be covered as one it does. Our Delaware insurance requirements page sets out the framework.

Reserve funding. A reserve study prices the replacement of components the association is responsible for. Boat ramps, bulkheads and piers are expensive components, and in Delaware most planned communities have no statutory reserve mandate at all — DUCIOA's requirement reaches condominiums and cooperatives. Our Delaware reserve studies page covers that gap, which a bill to close died in committee in June 2026.

One local note worth recording

Swann Keys is a low-lying Sussex County waterfront community, and the facilities at issue are water-access structures. That is the same category of asset now driving the coastal cost problem elsewhere in the county — where one condominium association's flooding exposure has produced per-unit elevation estimates in the tens of thousands of dollars. Owning the structure is the precondition for being able to fund, permit or replace it.

What to watch next

The Supreme Court affirmed on the basis of the Chancery opinion rather than writing its own, so the reasoning above is Delaware law without an appellate gloss. The reserved nuisance claim was left for the trial court.

No Delaware decision has yet addressed whether an association's expenditure of assessment funds on land it does not own is itself a breach of duty — a question that follows naturally from this fact pattern and that no reported case appears to reach.
