What Every Contract Must Include to Be Valid and Enforceable
“We had a contract. But it turned out to be invalid – it was missing the basics.”
Iveta signed a contract for roof repairs. Everything was agreed and signed. But when a dispute over quality arose, the opposing lawyer claimed the contract was invalid – it lacked a clear description of the work and the price. The court agreed. Without those elements, the contract wasn’t enforceable.
What every contract must include to be valid, which elements are mandatory, the most common mistakes, what can lead to invalidity, and how to catch these issues early.
📄 Essential elements of every contract
To be legally valid and enforceable, a contract must include:
Identification of both parties (name, ID number, address, representative)
Subject of the contract – what the agreement covers
Expression of mutual consent – agreement to the terms
Legal form – typically written, but oral can suffice in some cases
Date and signatures
⚠️ Most common mistakes
Unclear subject matter
Incomplete party identification (e.g., name but no ID number)
Missing price, payment method, or deadlines
Vague or inconsistent wording, often from combining templates
Contract is not signed or not dated
🧑⚖️ Why it matters
Without the essentials:
you lack certainty about the actual agreement,
the other party can challenge the contract,
you have no proof in court of what was agreed,
it’s often impossible to enforce performance or apply penalties.
📚 Real-life example:
A client signed a contract for developing a web application. But the contract didn’t specify any required features. The developer delivered “something,” but the client was unhappy – and had nothing concrete to rely on. The court ruled the contract too vague to enforce a specific outcome.
✅ Lawyer’s recommendation:
Even simple contracts need structure. Don’t rely on “it’ll work out.” A brief consultation can go a long way – we’ll make sure your contract protects your interests.
