Plain‑English definitions of the legal terms you’re likely to meet when buying, selling, renting, or owning a home in England.
If you’ve ever tried to read a property contract or a tenancy agreement and felt lost, you’re not alone. Legal language can sound like a different dialect. This glossary pulls together the words and phrases that come up again and again in my day‑to‑day work as a solicitor specialising in residential property. I’ve explained each one as I would to a client sitting across the desk — no jargon, just practical meaning.
Use the list to check something you’ve just spotted in your paperwork, or just browse to build your confidence before a move.
- Assured Shorthold Tenancy (AST): The most common type of private tenancy in England. An AST gives a landlord a guaranteed right to repossess the property after a fixed term (usually six or twelve months) provided the correct legal notice is served. Most written tenancy agreements create an AST automatically if the rent is below £100,000 a year and the tenant uses the property as their main home.
- Chain: A linked series of property transactions. You buy a house, the person you’re buying from is buying another, and that seller is buying yet another. A chain only completes when every transaction in the series is ready to exchange and complete on the same day. Chains are a major source of delay and stress — something I often help clients navigate by keeping communication clear.
- Completion: The final step of a property sale or purchase. On the completion date, the buyer’s money is transferred to the seller’s solicitor, the keys are handed over, and legal ownership moves. After completion, the buyer can move in (or start letting the property). The completion date is fixed at exchange of contracts; missing it usually means paying contractual interest.
- Conveyancing: The legal work that transfers ownership of land or a building from one person to another. It covers everything from drafting and checking the contract, carrying out searches, managing the mortgage and the transfer deed, to registering the new owner at HM Land Registry. In England this is usually handled by a solicitor or a licensed conveyancer.
- Covenant: A rule written into the title deeds that says what you must or must not do on your land. Positive covenants require you to do something — for example, maintain a shared fence. Restrictive covenants stop you from doing something, like running a business from the property or building an extension without consent. Covenants can stay with the land for decades, so checking them early is essential.
- Deposit (tenancy):A payment made by a tenant at the start of a tenancy, usually equal to four or five weeks’ rent. Since 2007, deposits for Assured Shorthold Tenancies must be placed in a government‑approved deposit protection scheme. The scheme holds the money securely and provides a free dispute service if landlord and tenant disagree about deductions at the end of the tenancy.
- Deposit (purchase):The share of the purchase price a buyer pays from their own funds, with the rest covered by the mortgage. Exchange of contracts requires the buyer to pay a deposit (typically 5–10% of the price, paid to the seller’s solicitor as stakeholder). If the buyer pulls out after exchange, they usually forfeit this deposit.
- Easement:A right held by one property to use another’s land in a specific way. Common examples include a right of way (a footpath or driveway over a neighbour’s plot), light, drainage, or parking. Easements are often set out in the title register and can affect property value and everyday enjoyment — something I always flag when reviewing title documents.
- Exchange of contracts:The point when a buyer and seller become legally bound to complete the transaction. Each side’s solicitor posts or hands over their signed contract, and the deposit is transferred. Before exchange, either party can pull out without penalty; after exchange, pulling out has serious financial consequences. I always make sure my clients understand that exchange is the moment of no return.
- Freehold:Outright ownership of a property and the land it stands on, for an unlimited period. Most houses are freehold. The owner is responsible for the building’s upkeep and any obligations in the deeds. With a freehold there is no ground rent or service charge payable to a superior landlord.
- Gazumping / Gazundering:Gazumping happens when a seller accepts a higher offer from another buyer after previously accepting yours, but before contracts are exchanged. Gazundering is the reverse: the buyer lowers their offer at the last minute, often by threatening to pull out just before exchange. Neither is illegal but both can waste thousands in sunk costs. They are a stark reminder of the importance of moving swiftly and being prepared.
- Ground rent:A regular payment a leaseholder makes to the freeholder, simply for the right to occupy the land. Ground rents are set out in the lease. Many modern long leases charge a peppercorn — a tiny or zero sum — but some older or more complex arrangements have substantial rents that double every few years. High or doubling ground rents can make a property difficult to sell or mortgage.
- Land Registry (HM Land Registry):The government department that records legal ownership and interests in land in England and Wales. After completion, the buyer’s solicitor applies to register the new owner. The register contains three parts: the property register (describes the land), the proprietorship register (who owns it), and the charges register (mortgages, covenants, easements). The register is the authoritative source of ownership proof, replacing paper title deeds for most properties.
- Leasehold:Ownership of a property for a fixed number of years, granted by the freeholder. Most flats are leasehold. At the end of the term, the property reverts to the freeholder, though residential long leases often start at 99,125, or even 999 years. Leaseholders typically pay ground rent and a service charge for maintenance of shared areas and the structure. The lease itself sets out what you can and cannot do — pet restrictions, alterations, sub‑letting — so reading it carefully is crucial.
- Mortgage:A loan secured against a property. The lender’s interest is recorded on the registered title. If you fail to keep up repayments, the lender can ultimately repossess and sell the property. Adviser on affordability and different mortgage types is outside my practice, but I work with lenders’ solicitors to make sure the mortgage deed is in place and that funds are available by completion.
- Searches:Specific enquiries made by a buyer’s solicitor during conveyancing. Common searches include the local land charges search (planning, building control, contaminated land, tree preservation orders), a water and drainage search, and an environmental report. The results reveal risks that aren’t obvious from a viewing — planned road schemes, financial charges attached to the property, rights of way, and flood risk, for example. Reviewing searches carefully is one of the most important jobs I do for a buyer.
- Section21 Notice:A legal notice a landlord can serve to end an Assured Shorthold Tenancy without having to give a reason, provided the tenancy has passed its fixed term or is periodic. There are strict rules about timing, form, and prerequisites (like valid gas safety and EPC certificates) — if they aren’t met, the notice is invalid. This area of law is deliberately protective of tenants, so it’s worth taking advice if you receive one.
- Service charge:A payment made by a leaseholder to cover the costs of maintaining and insuring the building and common parts. The lease sets out which costs can be included, how often they are reviewed, and how much the landlord can demand. Service charges must be reasonable, and leaseholders have rights to challenge excessive demands and to see how the money is spent. Sudden large increases often spark disputes, so keeping the accounts under review is wise.
- Samp Duty Land Tax (SDLT):A tax paid by the buyer on most property purcases in England. The amount depends on the purchase price, whether you own other properties, and whether you are a first‑time buyer. Your solicitor calculates the tax and files the return after completion; payment must reach HM Revenue & Customs within14 days. Getting SDLT wrong can mean a penalty, so double‑checking the calculation and claiming any relief (like first‑timer relief) is part of a thorough conveyancing service.
- Title / Title Deeds:The legal right of ownership of land. Historically, title was proved by a bundle of paper deeds; today, for registered land the official record at HM Land Registry is the title. When I “check title” for a buyer, I examine the register entries to spot anything that might affect use, value, or the ability to get a mortgage — such as missing rights of way, restrictive covenants, or third‑party charges.
This glossary covers the words people most often look up, but the practical meaning of a term can shift depending on the facts of a specific case. If something on your paperwork bothers you, it’s always worth asking a solicitor for a personalised explanation.
