Assawoman Landlord-Tenant Lawyer, Virginia

When a landlord provides housing that is so substandard that a landlord has legally evicted the tenant. For example, if the landlord refuses to provide heat or water or refuses to clean up an environmental health hazard, the tenant has the right to move out and stop paying rent, without incurring legal liability for breaking the lease.

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.

A legal doctrine that prevents a plaintiff who has acted unethically in relation to a lawsuit from winning the suit or from recovering as much money as she would have if she had behaved honorably. For example, if a contractor is suing a homeowner to recover the price of work he did on the home, his failure to perform the work as specified would leave him with unclean hands.

A contract in which an owner leases her house (usually for one to five years) to a tenant for a specific monthly rent, and which gives the tenant the right to buy the house at the end of the lease period for a price established in advance. A lease option is often a good arrangement for a potential home buyer because it lets him move into a house he may buy without having to come up with a down payment or financing at that time.

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.

The power of the federal or state government to take private property for a public purpose, even if the property owner objects. The Fifth Amendment to the United States Constitution allows the government to take private property if the taking is for a public use and the owner is 'justly compensated' (usually, paid fair market value) for his or her loss. A public use is virtually anything that is sanctioned by a federal or state legislative body, but such uses may include roads, parks, reservoirs, schools, hospitals or other public buildings. Sometimes called condemnation, taking or expropriation.

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.'

Personal property that has no physical existence, such as stocks, bonds, bank notes, trade secrets, patents, copyrights and trademarks. Such 'untouchable' items may be represented by a certificate or license that fixes or approximates the value, but others (such as the goodwill or reputation of a business) are not easily valued or embodied in any instrument. Compare tangible property.

Principles of international law so fundamental that no nation may ignore them or attempt to contract out of them through treaties. For example, genocide and participating in a slave trade are thought to be jus cogens.
