A wedding planner contract is your legal safety net—it spells out exactly what you're paying for, when, and what happens if plans change. Without one, you're relying on handshakes and text messages, which leads to scope creep, surprise bills, and stressed conversations weeks before your big day. Here's what to scrutinize before signing.
The Service Scope Section
This is the contract's backbone. It should clearly list every single task your planner will handle: venue sourcing, vendor coordination, timeline creation, day-of logistics, guest communication, design execution, or budget management. Don't accept vague language like "full planning services"—insist on specifics.
Check whether your planner handles tasks like:
- Negotiating vendor contracts and pricing
- Attending all vendor meetings
- Creating and distributing timelines to your wedding party
- Managing the final walkthrough at your venue
- Coordinating setup, ceremony, and reception timing on the wedding day
- Handling vendor payments and tips
If something isn't listed, assume your planner won't do it. This protects both parties from mismatched expectations.
Payment Structure and Timing
Wedding planner fees typically range from $2,500 to $10,000+ depending on your location, guest count, and complexity. Some charge a flat fee; others charge a percentage of your total budget (usually 10–15%). Some add event day fees on top.
Look for:
- Total cost breakdown – flat fee, percentage, hourly rate, or hybrid model
- Payment schedule – when each installment is due (common: 50% at signing, 50% at wedding, or divided into thirds)
- What's included in each payment – does your final payment cover the day-of coordination, or is that extra?
- Cancellation fees – how much do you lose if you cancel 6 months out versus 2 weeks out?
- Refund terms – are deposits refundable if the planner doesn't deliver services?
Request a written invoice schedule in the contract itself, not just a verbal agreement.
Liability and Change Management
Contracts should address what happens when things go wrong. Look for language about:
- Liability limits – most planners cap liability at the fee you paid them, meaning they won't cover the cost of your entire wedding if a vendor fails (which is fair)
- Change orders – if you want to add services mid-planning, how will that be billed?
- Venue or date changes – if you postpone your wedding, does your planner redo planning for free or charge a rescheduling fee?
- Vendor no-shows – is the planner responsible for vetting vendors, or do you share the risk?
A solid contract will state: "If a booked vendor cancels, Planner will provide a list of three alternative vendors within 48 hours." That's accountability.
Timeline and Availability
Your contract should specify when your planner is available for meetings, how they communicate (email, phone, project management app), and response time expectations. A realistic clause reads: "Planner will respond to client communications within 48 business hours."
Also nail down the planning timeline. If you're 18 months out, your planner should outline quarterly check-ins. If you're 3 months away and hiring them for day-of coordination only, define exactly when meetings happen.
Vendor Agreements and Commissions
Some planners earn commissions from vendors (caterers, photographers, florists) on top of their service fee. This is normal, but it should be disclosed. A transparent contract states: "Planner may receive commissions from vendors; these do not increase your costs."
Ask your planner to confirm in writing that they don't have exclusive vendor relationships that limit your choices, especially for critical vendors like caterers and photographers.
Negotiation Tips
- Get it in writing – verbal agreements aren't enforceable in most cases
- Define "wedding day" – how many hours of day-of coverage do you actually get? Is it 10 am to midnight, or 4 pm to 10 pm?
- Clarify add-ons – what costs extra? (Engagement party planning, rehearsal dinner coordination, day-after brunch?)
- Request references – before signing, talk to 2–3 couples who used this planner
Services like Mercoly help you compare and find trusted wedding planners in one place, making it easier to review multiple contracts side-by-side before deciding.
Frequently Asked Questions
Q: Can I negotiate the payment schedule in the contract? Yes. If a planner demands 100% upfront, that's a red flag. A reasonable structure is 50% deposit, 25% at 2 months before, 25% at wedding. Some planners offer installment plans.
Q: What happens if my planner quits mid-planning? Your contract should specify an exit clause stating the planner will introduce you to a recommended replacement or refund a prorated portion of your fee. Without this, you're unprotected.
Q: Is it normal for a planner to charge extra for a wedding over 200 guests? Often, yes. Larger guest counts mean more vendor coordination and logistics. This should be clarified in the contract—ask if your quoted fee covers your expected guest count.
