Real estate law is the body of rules that governs how land, and anything permanently attached to it, is owned, used, transferred, financed, and regulated. It reaches into nearly every property transaction in the United States, whether you are buying a first home, signing a lease, inheriting a house, or developing a commercial site. Federal statutes layer on fair housing protections, lending disclosures, environmental limits, and tax rules; state and local law add zoning, recording requirements, landlord-tenant procedures, and the mechanics of foreclosure. Taken together, these rules decide what you can build, what you must disclose, what you owe, and what remedies you have when something goes wrong.
What Counts as Real Property
The first distinction in property law is between real property and personal property. Real property is the land plus anything permanently attached to it: the house, the garage, a retaining wall, a built-in appliance. Personal property is everything movable, like furniture or a vehicle. The line matters because real property follows its own rules for ownership, transfer, and taxation.
The most complete form of ownership is fee simple absolute. You can use the land, lease it, sell it, or leave it to heirs, with no conditions attached. Most single-family homeowners hold title this way, even if they never use the term.
Co-ownership comes in several forms, and the choice has consequences that often surface years later during a death or divorce. Joint tenancy gives each owner an equal share, and when one owner dies, that share passes automatically to the survivors rather than through the deceased’s will. Tenancy in common allows unequal shares, and each owner can leave their share to whomever they choose. Tenancy by the entirety is available only to married couples in states that recognize it; neither spouse can sell or encumber the property alone, which shields the home from one spouse’s individual creditors.
Deeds, Title, and Title Insurance
A deed is the document that transfers ownership from one person to another. Once signed, it should be recorded with the local county recorder so the public has notice of the change. Recording is what protects a buyer against a seller who tries to convey the same property twice.
Title is the legal right to own and possess the property. Before closing, a title search goes through the public records to confirm the seller actually has authority to transfer ownership and to surface anything attached to the land, like unpaid liens or old easements. Title insurance then protects the buyer and lender against defects the search missed, including unknown liens, forged documents in the chain of title, and undisclosed encumbrances.1Consumer Financial Protection Bureau. What Is Owner’s Title Insurance? Unlike other insurance, it covers problems that already existed at purchase but had not yet been discovered.
Easements, Liens, and Adverse Possession
Other people can hold rights in your land even when you own it. An easement allows someone to use part of your property for a specific purpose, most commonly a utility easement for power or water lines. Easements run with the land and bind future owners.
A lien is a legal claim that secures a debt. Mortgage liens, tax liens, and mechanic’s liens from unpaid contractors all qualify. A lien does not transfer ownership, but unpaid debts can force a sale, and liens almost always have to be cleared before title changes hands.
Adverse possession is the doctrine that lets someone who openly occupies another person’s land long enough to eventually claim ownership of it. The possession generally must be continuous, open and obvious, hostile (without the owner’s permission), actual, and exclusive. Statutory time periods vary widely by state. The practical takeaway is that ignoring a trespasser or an encroaching fence for too long can cost you part of your land.
Buying and Selling Property
Every real estate purchase runs on a written contract, usually called a purchase agreement. Nearly every state requires contracts for the sale of land to be in writing under the statute of frauds. The agreement sets out the price, a legal description of the property, any contingencies that let the buyer back out, and the closing date.
Sellers must disclose known material defects, such as a leaking roof, foundation cracks, or mold. For housing built before 1978, federal law adds another obligation: sellers and landlords must disclose any known lead-based paint hazards, provide the EPA pamphlet on lead safety, and give buyers a 10-day window to inspect for lead before the contract becomes binding. Signed copies of these disclosures must be kept for three years.2U.S. Environmental Protection Agency. Real Estate Disclosures About Potential Lead Hazards
At closing, the buyer signs the loan documents, the seller signs the deed, funds are disbursed, and the deed is recorded. Outstanding liens are either paid from the seller’s proceeds or negotiated as part of the deal.
Financing the Purchase
Most buyers finance with either a mortgage or a deed of trust, and the difference matters. A mortgage is a two-party arrangement between you and the lender; if you default, the lender has to go through a court-supervised foreclosure to take the property. A deed of trust adds a neutral trustee who holds legal title as security until the loan is paid off. In states that use deeds of trust, the trustee can often sell the property without court involvement, making foreclosure faster.
Federal law requires lenders to deliver standardized documents so you can understand what the loan actually costs. Under the TILA-RESPA Integrated Disclosure rules, you must receive a Loan Estimate within three business days of applying, and a Closing Disclosure at least three business days before you finalize the loan, so you can compare the final numbers against the original quote.3Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs
The Real Estate Settlement Procedures Act bars anyone involved in a closing from paying or taking referral fees or kickbacks for steering business to a particular provider, and prohibits fee-splitting unless real services were performed. Violations carry criminal penalties of up to $10,000 and one year in prison, plus civil liability for three times the improper charge.4Office of the Law Revision Counsel. 12 USC 2607 – Prohibition Against Kickbacks and Unearned Fees
Fair Housing
The Fair Housing Act makes it illegal to discriminate in the sale, rental, or financing of housing based on seven protected characteristics: race, color, national origin, religion, sex, familial status, and disability.5Office of the Law Revision Counsel. 42 USC 3604 – Discrimination in the Sale or Rental of Housing The ban reaches obvious conduct, like refusing to rent to a family with children, and more subtle practices, like steering buyers toward certain neighborhoods or quoting different loan terms based on national origin.
Disability protections go further. Housing providers must allow reasonable modifications to the physical space, such as a wheelchair ramp, and reasonable accommodations to rules and policies, such as waiving a no-pets rule for a service animal. The tenant usually pays for structural modifications, unless the housing receives federal financial assistance, in which case the provider typically bears the cost. Complaints go to HUD or a local fair housing agency, and violations can produce significant civil penalties.
Common Property Disputes
Owning real property means dealing with disputes sooner or later. The categories below cover most of what owners actually encounter.
Boundary and Quiet Title Actions
Boundary disputes happen when neighbors disagree about where one property ends and the next begins. Unclear surveys, misplaced fence posts, and encroachments by sheds or driveways are the usual triggers. Some are solved by a new survey; others go to court, particularly where one side claims adverse possession.
A quiet title action is a lawsuit filed to establish definitive ownership and extinguish competing claims. It comes up when records are ambiguous, when an heir’s interest was never properly transferred, or when someone asserts ownership through adverse possession. A successful judgment makes the property marketable again.
Landlord-Tenant Problems
Eviction is the most consequential landlord-tenant dispute. A landlord cannot change the locks; eviction requires written notice, a waiting period, and a court order in every state. The common grounds are nonpayment of rent and material lease violations. Security deposit disputes are nearly as frequent, and state law controls how much a landlord can collect, where the deposit must be held, what deductions are permitted, and how soon the balance must be returned after move-out.
Foreclosure
When a borrower stops paying, the lender can foreclose and sell the property to recover the debt. Some states require a court proceeding; others allow a nonjudicial sale through the deed of trust’s power-of-sale clause.
Federal rules add protections before foreclosure begins. Under Regulation X, a mortgage servicer cannot make the first foreclosure filing until the borrower is more than 120 days behind. If the borrower submits a complete loss mitigation application during that window, the servicer must evaluate it before moving forward with foreclosure.6eCFR. 12 CFR 1024.41 – Loss Mitigation Procedures A complete application submitted more than 37 days before the scheduled sale can also pause the process. These rules exist to prevent “dual tracking,” where a servicer reviews alternatives while simultaneously pushing toward a sale.
Contract Disputes
Real estate contract disputes usually come from a buyer or seller failing to meet their obligations. If a seller refuses to close, the buyer can seek specific performance, a court order compelling the sale. That remedy is more common in real estate than in other contract law because every parcel is treated as unique. The non-breaching party can also pursue monetary damages for losses caused by the breach.
Government Regulation of Property
Government shapes what you can do with your land at every level, sometimes in ways new owners do not expect.
Zoning and Variances
Local governments divide land into zones, typically residential, commercial, and industrial, with rules on what structures you can build, how tall they can be, and how far they must sit from property lines. Zoning keeps incompatible uses apart but also limits what you can do with your own land.
If a rule makes your property unusually hard to use, you can apply to the local board of adjustment for a variance. Variances are not easy to get. You generally must show that strict application causes a genuine hardship specific to your property, that it is not neighborhood-wide, and that you did not create it yourself. Simply preferring a different use is not enough.
Eminent Domain
The government can take private property for public use even over the owner’s objection. The Fifth Amendment limits that power by requiring “just compensation” whenever private property is taken.7Constitution Annotated. Fifth Amendment – Overview of Takings Clause Just compensation is generally the property’s fair market value at the time of the taking. Common examples are land for roads, schools, and utility corridors. Owners who believe the government’s offer is too low can challenge the valuation in court.
Property Taxes
Property taxes are the main revenue source for most local governments, paying for schools, fire protection, and infrastructure. A local assessor sets the fair market value, and the tax rate is applied to that figure. Most jurisdictions let you appeal an assessment within a set deadline. Unpaid property taxes become a lien and can lead to a tax sale, where the government auctions either the lien or the property itself.
Environmental Limits
Environmental laws can restrict what you build and where. The Clean Water Act regulates discharges into navigable waters and requires permits for activities that fill or dredge wetlands and waterways.8U.S. Environmental Protection Agency. Summary of the Clean Water Act Section 404 of the Act requires a federal permit before any dredged or fill material can be placed in navigable waters, which includes many wetlands that developers do not immediately recognize as regulated.9Office of the Law Revision Counsel. 33 USC 1344 – Permits for Dredged or Fill Material Federal and state hazardous materials laws can also require expensive assessments and cleanup before development, and skipping those steps risks fines, project shutdowns, and personal liability for contamination.
Taxes When Property Changes Hands
Real estate carries tax consequences beyond the annual property bill. Three federal rules show up often enough to affect what you keep.
Home Sale Exclusion
When you sell your home at a profit, you can exclude up to $250,000 of the gain from federal income tax, or up to $500,000 for joint filers. You must have owned and used the home as your primary residence for at least two of the five years before the sale, and you cannot use the exclusion more than once every two years.10Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence
Section 1031 Exchanges
If you sell investment or business real estate and reinvest in similar property, a Section 1031 exchange lets you defer capital gains tax. Since 2018, this applies only to real property, not equipment or vehicles. The deadlines are strict: identify the replacement property within 45 days of the sale and close within 180 days.11Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment Missing either deadline disqualifies the exchange. Property held primarily for sale, like a flipped house, does not qualify, and U.S. real property is not considered like-kind to foreign real property.
FIRPTA Withholding
When a foreign person sells U.S. real estate, the buyer must withhold 15% of the sale price and remit it to the IRS under the Foreign Investment in Real Property Tax Act. The withholding drops to zero if the buyer intends to use the property as a residence and the sale price is $300,000 or less.12Internal Revenue Service. FIRPTA Withholding Many domestic buyers do not realize they are personally responsible for the withholding and can face penalties if they fail to do it.
When to Hire a Real Estate Attorney
Not every real estate matter needs a lawyer. A straightforward home purchase in a state where title companies handle the closing paperwork is often manageable without one. Other situations are worth the fee: commercial transactions with complex lease or financing terms, boundary disputes a survey alone cannot resolve, any foreclosure or eminent domain proceeding where your equity is at stake, and title defects that make the property hard to sell. A real estate attorney reviews documents, flags risks that are easy to miss, and represents you in court or before a zoning board when negotiation fails. The cost of counsel is almost always less than the cost of the mistake it prevents.
