Short answer
The three C's are clarity, certainty, and consent. A contract must be clear about what is agreed, certain enough to be enforceable, and consented to freely by both parties. Without these, the contract may be weak or unenforceable.
Think of the three C's as the foundation of any good wedding contract. Clarity means the terms are written in plain language that both sides understand. No vague phrases like 'reasonable number of guests' or 'as agreed later'. Certainty means the contract pins down the essentials: the date, the time, the venue, the services, the price, and the payment schedule. If a key term is missing or open-ended, a court may say the contract is too uncertain to enforce. Consent means both parties signed willingly, without pressure, and understood what they were agreeing to.
For your wedding, apply the three C's when you review every supplier contract. Ask the venue to specify the exact room, the hours you have access, and what is included in the hire. Ask the caterer to list the menu, the number of guests, and what happens if numbers change. Ask the photographer to state how many hours of coverage, how many edited photos, and when you will receive them. If anything is vague, ask for it to be written down.
Consent is usually straightforward, but be careful if a supplier uses high-pressure sales tactics. You should never feel rushed into signing. Take the contract home, read it calmly, and discuss it with your partner. If a term is unclear, ask for clarification before you sign. A good supplier will welcome your questions. If they refuse to put something in writing, that is a red flag. The three C's protect you, so use them as your checklist before you hand over any deposit.
