Contract Terms

TermDefinition
ConsiderationSomething of value exchanged — makes a contract binding. Can be money, services, or even a promise.
IndemnificationPromise to cover someone's losses if something goes wrong — "I'll pay if you get sued because of my work"
Force Majeure"Act of God" clause — excuses performance due to unforeseeable events (natural disaster, war, pandemic)
SeverabilityIf one part of the contract is invalid, the rest still stands

Liability & Negligence

TermDefinition
NegligenceFailure to exercise reasonable care — 4 elements: duty, breach, causation, damages
LiabilityLegal responsibility for your actions or omissions
Strict LiabilityResponsibility regardless of fault — common in product liability cases

Intellectual Property

TermDefinition
PatentExclusive right to an invention — 20 years from filing
TrademarkProtects brand identifiers — names, logos, slogans. Can last forever if used and defended.
Trade SecretConfidential business information (Coca-Cola formula, Google algorithm)
Pro Tip: If a contract has a section titled 'Indemnification,' read it three times. It's often the most dangerous clause — you could be agreeing to pay someone else's legal bills. If you don't understand it, a lawyer's $300 review fee is cheaper than unlimited liability.
