9.1 Determining Property Ownership and Responsibility

Key Takeaways

  • Real property is land and whatever is permanently attached to it; personal property is everything else that can be owned, including intangible property such as intellectual property.

  • Ownership interests include fee simple, life estates, leaseholds, and concurrent ownership (tenancy in common, joint tenancy with right of survivorship, tenancy by the entirety), each with its own insurable interest.

  • A bailment is possession of another's personal property for a purpose; the bailee's duty of care varies with who benefits, and bailee exposures are commonly insured through inland marine or bailee coverage.

  • Traditionally, a landowner owes trespassers little, licensees warnings of known hidden dangers, and invitees reasonable care including inspection; many states now use a single reasonable-care standard.

  • Secured interests such as mortgages and liens give lenders an insurable interest, protected under a policy's mortgage or loss payable clause.

Determining Property Ownership and Responsibility

Quick Answer: Property law answers two insurance questions: who has an insurable interest and who is responsible when someone is hurt or property is damaged. Real property is land and what is attached to it, and personal property is everything else. Several people can hold interests in the same property at once: owners, tenants, lenders, and bailees. Each may need its own coverage. Landowners owe different duties to trespassers, licensees, and invitees, and bailees owe duties based on who benefits from the bailment.

Why It Matters

Property insurance pays those with an insurable interest at the time of loss. Liability insurance responds when an insured is legally responsible for harm. Both depend on property law. Identifying every party with a stake in a building or its contents avoids gaps, such as a tenant who assumes the landlord's policy covers the tenant's improvements.

Real Property vs. Personal Property

Intangible personal propertyProperty rights without physical formAccounts receivable, patents, trademarks, dataSpecialized coverages; generally not "tangible property" under liability policies

Improvements a tenant makes at its own expense usually become the landlord's real property when attached. The tenant still has a use interest during the lease, which is why commercial property forms let tenants insure improvements and betterments.

Forms of Ownership

InterestKey featureInsurable interest
Fee simple absoluteThe most complete ownership; may be sold or inheritedFull value
Life estateOwnership for a person's lifetime; then passes to a remaindermanLife tenant and remainderman both have interests
LeaseholdRight to possess for a lease termTenant's improvements, use interest, and legal liability
Tenancy in commonCo-owners hold separate shares; a share passes by will or inheritanceEach owner to the extent of the share
Joint tenancy with right of survivorshipEqual co-owners; a deceased owner's share passes to the survivorsEach joint tenant
Tenancy by the entiretyJoint ownership by spouses, available in some statesBoth spouses

Other interests include easements (rights to use another's land, such as a utility easement) and licenses (permission to enter).

Secured Interests

Lenders and sellers on credit hold security interests:

  • Mortgage: A lender's interest in real property securing a loan. Property policies protect the lender through a mortgage clause. Under the standard ISO wording, the lender can recover even if the owner's claim is denied for the owner's own acts, provided the lender meets its conditions.
  • Liens: Claims against property for unpaid debts, such as a mechanic's lien for unpaid construction work.
  • Security interests in personal property: For example, an auto lender protected under a loss payable provision.

Bailments

A bailment occurs when one party (the bailor) gives possession of personal property to another (the bailee) for a purpose, such as repair, storage, cleaning, or transport, with the expectation that it will be returned.

Type of bailmentWho benefitsTraditional bailee standard of care
For the sole benefit of the bailorBailor only (e.g., a friend stores your boat for free)Slight care; liable only for gross negligence
Mutual benefitBoth (e.g., a dry cleaner paid to clean clothes)Ordinary (reasonable) care
For the sole benefit of the baileeBailee only (e.g., borrowing a neighbor's trailer)Great care; liable even for slight negligence

Many states now apply a general reasonable-care standard. Some bailees, such as common carriers, face near-strict liability by statute. Bailees can buy bailee coverage that pays for customers' goods regardless of fault, which protects customer goodwill as well as the bailee's legal liability.

A Landowner's Duties to People on the Property

EntrantWho they areTraditional duty owed
TrespasserOn the land without permissionRefrain from willful or wanton injury; duties rise once trespassers are known or expected
LicenseePresent with permission for their own purpose (social guests)Warn of known dangerous conditions the licensee is unlikely to discover
InviteePresent for the owner's business or open to the public (customers)Reasonable care, including inspecting for hazards and fixing or warning of them

Attractive nuisance: A landowner may be liable to trespassing children injured by an artificial condition, such as a pool or machinery, that is likely to attract them. This applies when the owner knows children are likely to trespass and the risk could be reduced at reasonable cost.

Many states have replaced some or all of these categories with a single duty of reasonable care under the circumstances. Always check the governing jurisdiction.

Landlord and Tenant Responsibilities

  • Landlords generally remain responsible for common areas and for hidden defects they know about.
  • Tenants generally control and are responsible for the leased premises.
  • Leases often shift responsibility through hold-harmless clauses and insurance requirements, such as naming the landlord as an additional insured and adding mutual waivers of subrogation.

Worked Scenario: Who Has an Insurable Interest?

A restaurant leases a building. The landlord's bank holds a mortgage, the tenant installed a $150,000 kitchen, and a produce vendor stores a refrigerated trailer on site under a service contract. After a fire:

  • Landlord: Building interest, insured under the landlord's building coverage.
  • Bank: Mortgagee interest, protected by the mortgage clause on the landlord's policy.
  • Tenant: Improvements and betterments (use interest) and its own business personal property.
  • Vendor's trailer: The restaurant, as bailee, may be liable if negligent. The vendor's own inland marine or auto physical damage coverage protects the vendor's ownership interest.

Test Your Knowledge

A shopper slips on a spill that a store employee could have found during routine inspection. Under the traditional classifications, what duty did the store owe the shopper?

A

Reasonable care, including inspecting for and correcting or warning of hazards, because the shopper is an invitee

B

Only to avoid willful or wanton injury, because the shopper is a trespasser

C

Only to warn of known hidden dangers, because the shopper is a licensee

D

No duty, because landowners are never liable for spills
