Contracts are everywhere.
Some of them arrive as long, formal documents filled with clauses, signatures and language that appears carefully designed to make ordinary people slightly nervous. Others are created during perfectly routine moments, such as buying groceries, hiring someone to repair a door or subscribing to an online service.
In legal terms, a contract is not simply a document. It is a legally enforceable agreement between two or more parties.
A contract may be written down, agreed orally, signed electronically or formed through the conduct of the people involved. This means that you may enter into a contract without using legal language, signing a printed document or even saying a single word.
Do Contracts Always Have to Be in Writing?
No. Not every contract has to be written down.
Suppose you agree to buy an old garden chair from your neighbour for €40. Your neighbour agrees to sell it, and you agree to pay the price. Even if neither of you prepares a document, the conversation may still create an oral contract.
The same principle applies in many everyday situations.
You might ask a local tradesperson to repair a broken door. You agree on the work, the price and perhaps the day when the job will be completed. The tradesperson agrees to do the work. Although there may be no formal paperwork, the agreement can still have legal consequences.
Contracts may also be created through conduct.
When you place a carton of milk on a supermarket conveyor belt, you do not normally announce:
“I hereby offer to purchase this dairy product at the displayed price.”
That would certainly make the weekly shopping experience more theatrical, but it is unnecessary.
Your actions communicate your intention. You place the milk on the conveyor belt, the supermarket processes the sale, and you pay the price. A contract is created through what both sides do.
The same basic idea may apply when you board a bus, pay for parking, order food through an app, purchase a train ticket or subscribe to an online platform.
In each situation, the agreement may be communicated through behaviour rather than through a detailed conversation.

Is Every Agreement a Contract?
Every contract is an agreement, but not every agreement is a contract. This is one of the most important distinctions in contract law.
Two colleagues may agree to meet for lunch at one o’clock. A friend may promise to help you move a sofa at the weekend. A family member may say they will drive you to the airport.
These are all agreements or promises. However, they are not normally contracts.
If your friend suddenly develops a mysterious back problem on the morning of the move, you may be disappointed. You may even question the future of the friendship. You are unlikely, however, to have a successful legal claim for breach of contract.
The same problem can arise in business conversations.
A supplier might say:
“Everything should be fine.”
Or:
“Call me if there is a problem and we’ll sort something out.”
These statements may sound reassuring, but they do not automatically become contractual terms.
A court may need to consider the exact wording, the commercial context, the behaviour of the parties and whether the statement was intended to have legal effect. It may also consider whether one party relied on the promise and whether the statement formed part of the final agreement.
Not every promise, friendly assurance or informal understanding creates a legal obligation.
What Are the Essential Elements of a Valid Contract?
In common law systems, a valid contract normally requires five essential elements:
- Offer
- Acceptance
- Consideration
- Intention to create legal relations
- Capacity
Together, these elements help determine whether an agreement is legally binding and enforceable.
They are particularly important for anyone studying Engleză juridică, because the terms appear regularly in commercial contracts, employment agreements, legal correspondence, negotiations, business proposals and contract disputes.
The first element is usually the starting point of the entire process: the offer.
1. The Offer: A Clear Proposal to Enter into a Contract
What Is an Offer in Contract Law?
An offer is a clear proposal made by one party to another. It shows that the person making the proposal is willing to enter into a contract on specific terms.
The person making the offer is known as the offeror. The person receiving it is called the offeree.
For example:
“We offer to sell you 500 units at €20 per unit, with delivery by 30 September and payment within 30 days.”
This statement may be considered a legal offer because the main terms are clear.
It identifies the product, the quantity, the price, the delivery date and the payment period. The offeree therefore has enough information to understand the proposal and decide whether to accept it.
This is more than a general business conversation. It is a specific proposal that can receive a meaningful response.
Related terms: offeror, offeree, contractual terms, commercial offer, proposal, contract formation.
What Makes an Offer Legally Valid?
A valid offer must normally be sufficiently clear, definite and capable of acceptance.
Consider the following statement:
“I might be interested in buying some of your furniture.”
This is unlikely to be an offer.
The speaker has not identified which furniture they want, how much they are willing to pay or when the transaction should take place. The statement only communicates possible interest.
Now compare it with:
“I’ll buy the pine table and four chairs for €300.”
This statement is much more specific.
The items have been identified, the price is clear and the speaker appears ready to complete the transaction if the seller agrees. The other party can now respond with a clear yes or no.
The difference lies in certainty.
An offer must provide enough information for the other party to understand what they are being asked to accept.
Does an Offer Need to Include Every Detail?
An offer does not always need to contain every tiny detail of the future contract.
Some terms may be implied by law. Others may come from standard business conditions, established industry practices or documents that are incorporated into the agreement.
However, the essential terms must normally be clear enough for the other party to understand the proposal.
For example:
“We may be able to supply you with some equipment at a competitive price.”
This is probably not an offer.
What equipment will be supplied? How much will it cost? How many units are available? When will delivery take place?
There are simply too many unanswered questions.
Now consider:
“We will supply ten laptops for €600 each, with delivery to your Bucharest office by 15 October.”
This statement is far more precise.
It identifies the goods, quantity, price, delivery location and delivery date. It is therefore capable of being accepted.
The general rule is simple: the clearer the essential terms, the easier it is to identify a genuine offer.
Associated concepts: certainty of terms, price, quantity, subject matter, delivery, payment terms, contractual clarity.
Is an Advertisement a Legal Offer?
Not every advertisement, product listing or price display is a legal offer.
In contract law, advertisements and displays are often described as an invitation to treat.
An invitation to treat invites another person to make an offer. It is not usually an offer in itself.
This concept commonly applies to shop-window displays, supermarket shelves, catalogues, brochures, menus, price lists and online product pages.
Despite its rather sociable name, an invitation to treat is not an invitation to dinner. It is simply an invitation to begin the contract-making process.
What Is the Difference Between an Offer and an Invitation to Treat?
Imagine that a shop displays a laptop in its window with a price tag of €600.
At first glance, the display may look like a legal offer. The product is visible, the price is clear and the customer may be ready to pay.
However, the display will generally be treated as an invitation for customers to make an offer to buy the laptop.
There are several practical reasons for this.
The laptop may be a display model. The shop may have sold all the available stock. The price tag may contain a mistake. The item may already have been reserved for another customer.
It is also possible that two customers will enter the shop at exactly the same time, each holding €600 and each insisting that the laptop belongs to them.
If the display itself were automatically a binding offer, the shop could theoretically be required to sell the same laptop to more than one person. Contract law prefers to avoid impossible laptop situations.
The customer therefore makes the offer by saying something such as:
“I would like to buy that laptop for the displayed price of €600.”
The shop can then accept or reject the offer.
If the shop assistant replies:
“Certainly. How would you like to pay?”
the customer’s offer has been accepted.
The display attracted the customer. The customer made the offer. The shop accepted it.
Are Online Product Listings Legal Offers?
A product displayed on a website is also not necessarily a binding offer by the seller.
In many online transactions, the customer makes the offer by placing the product in a basket, completing the checkout process and submitting the order.
The seller may accept that offer later.
Acceptance might take place when the seller confirms the order, processes the payment, dispatches the goods or sends a formal acceptance email.
An automatic email stating that an order has been received does not always mean that the order has been legally accepted. It may simply confirm that the website has received the customer’s request.
The precise moment when the contract is formed will often depend on the wording of the website’s terms and conditions.
For this reason, phrases such as “order received”, “order confirmed” and “goods dispatched” may have different legal meanings.

How Can You Identify a Legal Offer?
When deciding whether a statement is an offer, ask a practical question:
Has the person made a clear and definite proposal that can be accepted immediately?
Alternatively, are they only inviting further discussion, negotiation or offers?
Statements such as:
“We may be able to offer a discount.”
“Prices start from €500.”
“Let us know if you are interested.”
“We could discuss delivery next month.”
normally suggest that discussions are still open.
They may eventually lead to an offer, but they are not necessarily offers themselves.
Now compare them with:
“We will provide the services described in the attached proposal for €2,500, provided that you confirm acceptance by Friday.”
This is far more likely to be considered an offer.
It identifies the services, the price, the method of acceptance and the deadline. The recipient knows what is being proposed and what must be done to accept it.
Key Point: The Role of an Offer in Contract Formation
An offer is the starting point of most contracts.
It must communicate a reasonably clear willingness to enter into a legally binding agreement on specific terms.
Once an offer has been made, the offeree has several possible responses. They may accept it, reject it, ignore it, request clarification or propose different terms.
When the offeree gives a clear and unqualified yes, we reach the second essential element of contract formation: acceptance.
