A legal claim that one party failed to perform as required under a valid agreement with the other party. For example you might say, 'The roofer breached our contract by using substandard supplies when he repaired my roof.'

A provision in a lease that absolves the landlord from responsibility for all damages, injuries or losses occurring on the property, including those caused by the landlord's actions. Most states have laws that void exculpatory clauses in rental agreements, which means that a court will not enforce them.

In a contract, a promise by one party not to hold the other party responsible if the other party carries out the contract in a way that causes damage to the first party. For example, many leases include a hold harmless clause in which the tenant agrees not to sue the landlord if the tenant is injured due to the landlord's failure to maintain the premises. In most states, these clauses are illegal in residential tenancies, but may be upheld in commercial settings.

Something that interferes with the use of property by being irritating, offensive, obstructive or dangerous. Nuisances include a wide range of conditions, everything from a chemical plant's noxious odors to a neighbor's dog barking. The former would be a 'public nuisance,' one affecting many people, while the other would be a 'private nuisance,' limited to making your life difficult, unless the dog was bothering others. Lawsuits may be brought to abate (remove or reduce) a nuisance. See quiet enjoyment, attractive nuisance.

Compensation to third parties who are injured or whose property is damaged due to the fault of the insurance holder. You may have liability insurance for your car or your home, or to cover actions you take in the course of your profession. Liability polices are sometimes called 'third-party policies.'

A person or entity (such as a corporation) that must be included in a lawsuit in order for the court to render a final judgment that will be just to everyone concerned. For example, if a person sues his neighbors to force them to prune a tree that poses a danger to his house, he must name all owners of the neighboring property in the suit.

A person to whom a property right is transferred. For example, an assignee may take over a lease from a tenant who wants to permanently move out before the lease expires. The assignee takes control of the property and assumes all the legal rights and responsibilities of the tenant, including payment of rent. However, the original tenant remains legally responsible if the assignee fails to pay the rent.
