Anatomy of a Contract: Elements and Validity Requirements

What is a Contract

A contract is an agreement between two or more parties that creates mutual rights and obligations, the fulfillment of which is ensured by law. Not every promise constitutes a contract. The contract requires several elements.

Elements of a Valid Contract

1. Offer and Acceptance — one party makes an offer, the other accepts it. The offer must include all essential terms. The acceptance must be full and unconditional (a counteroffer is a new offer).

2. Consideration / Causa (in common law countries — consideration, in continental law — causa): each party must receive something and give something. A gift agreement without consideration is not a binding contract in common law.

3. Legal Capacity of the Parties: the parties must have legal capacity — legal entities act through authorized persons, individuals upon reaching the age of majority and possessing capacity.

4. Legality of Subject Matter: a contract cannot obligate the parties to perform illegal actions.

5. Proper Form: certain contracts require a written form or notarization (real estate, corporate transactions, large loans).

Essential Terms of a Contract

A contract is deemed concluded if the parties have agreed on all essential terms. For sales — goods and price. For contract work — scope of work and deadlines. Lack of agreement on essential terms = contract not concluded.

Contract Interpretation

When parties dispute the meaning of a contract, the court applies rules of interpretation:

• Literal interpretation — the literal meaning of the words
• Teleological — based on the purpose of the contract
• Systematic — based on the meaning of the contract as a whole
• Contra proferentem — in case of ambiguity, interpretation against the party drafting the contract

Practical conclusion: it is important to carefully formulate the contract. The court will not "fix" a poorly drafted contract.

Practical Assignment

Find a standard office lease agreement. Determine: (1) Have all essential terms been agreed upon? (2) Which terms protect the landlord, and which — the tenant? (3) What risks are not covered by this contract?
