Oregon Real Estate Law 

Primary Legal Concerns for Home Buyers and Sellers

Under Oregon law, the seller has a legal duty to disclose all known information.  As  a general rule, a seller is legally required to deliver a property disclosure or disclaimer form.  The buyer then has five or seven business days, depending on the form used, to revoke his offer based on the information provided.  A seller can be held liable for any intentional misinformation or omissions on these forms.

For sellers, the main legal concerns are the buyer’s failure to close and the possible existence of some condition the seller doesn’t know about that may result in a dispute after the transaction has closed (for example, a leaky oil tank of which the seller was unaware).

Attorneys are often contacted after the agreement has been signed and  communication lines have been severed.  It is important to remember that attorneys are skilled in preventing disputes as well as resolving them, so it’s best to contact an attorney before finalizing any agreements.

Visit the Oregon Real Estate Agency FAQs page for information about real estate regulations in Oregon.  This is an good page forconsumers to get an overview of Oregon real estate law.

Each year the agency processes and tests more than 5,000 license applicants and monitors regulated activities in over 4,700 escrow and real estate offices. Land developers with offerings to Oregon citizens have thousands of disclosure filings with the agency.

The agency provides educational material and seminars for real estate professionals. The agency also conducts investigations and hearings when complaints are filed against licensees, registrants and real property developers.


With the advent of buyer’s agents, both buyers and sellers have the benefit of exclusive representation.  Real estate agents are required to disclose whom they represent and the terms of the representation by providing an agency disclosure form when a working relationship is initiated.

The primary duty an agent owes his client is to place his client’s interests above everyone else’s, including her/his own. To the party he does not represent, he must disclose all essential information about the property and treat that party fairly and honestly.  When a licensee represents both parties, limited representation applies.

While real estate agents perform vital functions in the industry, it is not wise or fair to ask them to provide services outside the scope of their profession.  Legal, tax, construction, inspection, title and financing concerns should be directed to professionals in those areas.

Real Estate Agency Disclosure Pamphlet

Agents in Oregon and Washington are required by law to provide an Agency Disclosure Pamphlet to the consumer, disclose whom they represent and the terms of that representation, and have the consumer acknowledge this agency representation. Understanding the different agency roles will assist you in choosing how you want to work with an agent in your real estate transaction.

These pamphlets describes agency relationships and the duties and responsibilities of real estate licensees in Oregon. This pamphlet is informational only and neither the pamphlet nor its delivery to you may be construed to be evidence of intent to create an agency relationship.


The issue of fairness in real estate law deals primarily with the parties acting in good faith, executing their best efforts, and treating everyone equally.  Under federal and/or Oregon law, a homeowner may not discriminate on the basis of race, color, sex, marital status, familial status, handicap, religion or national origin when negotiating price, terms or other conditions.  Cities and counties may also provide additional protection.

Lease-Options and Land Sale Contracts

Lease-options are a way of purchasing property by paying money (or other consideration) in addition to the rent, which is credited toward future purchase of the property.  Lease-options are, in effect, three separate agreements which are used to document the parties’ intent — lease, option, and purchase agreement.

Timing is essential with all the agreements, but particularly crucial with the option that the renter uses to notify the seller of his desire to buy.  As a rule, if the renter fails to exercise the option by the agreed date, the option money is forfeited, along with any interest in the property except for the right to inhabit under the terms of the lease.

A land sale contract is a form of seller financing wherein the seller retains legal title until the contract conditions are satisfied.  A land sale contract also provides the seller the right to declare forfeiture (take the property back) if the buyer defaults.  This remedy is generally faster and less expensive than foreclosure.

Oregon Law on Underground Oil Storage Tanks

USTA primary environmental concern for buyers and sellers is the presence of hazardous substances, including petroleum from underground heating oil storage tanks (USTs) and indoor pollutants.  With the large number of USTs in Oregon, steps should be taken to determine whether a tank exists and, if so, whether decommissioning and/or clean up are required.

According to the Department of Environmental Quality (DEQ), there are approximately 210,000 residential underground heating oil storage tanks in the State of Oregon. Oregon DEQ says there are approximately 60,000 underground heating oil tanks still in use and 150,000 that have been abandoned, i.e., not properly decommissioned.  Many of these tanks still contain fuel, and therefore pose potential environmental liability. Statistically 60-70% of underground heating oil tanks on record have leaked some product into the soil.

The rules and regulations about oil tanks are complicated.  If you purchase a home where an underground storage tank exists (average life of a tank is 25 years) and you were unaware of the tank when you purchased the home, you can undergo considerable financial expense if the tank begins to leak when you are the home owner or should you decide to sell it later.

Lead Paint

Lead is a soft, blue-gray, naturally occurring metal. It has been used for centuries for medicinal, industrial, commercial and household purpose. At the same time, lead that enters the body — especially when it happens to young children — can be quite toxic and destructive.

The US Department of Housing and Urban Development (HUD) estimates that 75% of the houses built before 1978 contain some lead-based paint. The director of that agency described lead as the “number one environmental threat to the health of children in the United States.” In 1992, the United States Environmental Protection Agency (EPA) and Agency for Toxic Substances and Disease Registry (ATSDR) issued a priority list of 275 hazardous substances. Lead was number one on that list.

Because it does not degrade or break-down, lead stays in the environment and unless it is handled properly, it has the potential to cause an ongoing cycle of health problems.
