What is Exchange of Contracts?
Exchange of contracts is the crucial point in property transactions where both buyer and seller become legally bound to complete the sale. Solicitors or conveyancers manage this process, preparing two identical contracts that outline all terms of the property sale including agreed price, legal descriptions, and completion date.
Key Contract Elements
Essential Contract Details
- • Purchase price: Final agreed sale amount
- • Property description: Full legal description and address
- • Completion date: Agreed date for final transaction
- • Fixtures & fittings: Items included in sale
- • Special conditions: Any unique arrangements
Legal Protections
- • Title guarantee: Seller's ownership confirmation
- • Property boundaries: Clear boundary definitions
- • Covenants & restrictions: Property use limitations
- • Rights of way: Access rights and easements
- • Planning permissions: Development rights status
Prior to exchange, both parties retain freedom to negotiate or withdraw without significant penalty. Once contracts are signed and exchanged, withdrawal results in serious financial and legal consequences, making this a pivotal moment providing security for both parties.
Pre-Exchange Requirements
Before exchanging contracts, several critical steps must be completed to ensure a smooth transaction. These preparations form the foundation for successful exchange and completion.
Essential Pre-Exchange Checklist
Offer Acceptance & Instructions
Initial offer accepted and solicitors/conveyancers instructed by both parties
Contract Drafting & Review
Seller's solicitor drafts contract, buyer's solicitor reviews and negotiates terms
Property Searches & Surveys
Local authority, environmental, water searches completed; property survey conducted
Mortgage Arrangements
Mortgage application processed, formal offer received, valuation completed
Final Preparations
Contracts signed, completion date agreed, all parties ready for exchange
Understanding the Exchange Deposit
The exchange deposit, typically 10% of the property's purchase price, demonstrates the buyer's commitment and provides security for the seller. This deposit is held by the seller's conveyancer until completion when the remaining 90% is paid.
💰 Deposit Scenarios & Consequences
Standard Deposit Calculation
Property value £300,000: Deposit = £30,000
Property value £500,000: Deposit = £50,000
Property value £750,000: Deposit = £75,000
Buyer Withdrawal Consequences
If buyer withdraws post-exchange without lawful reason: loses entire deposit plus potential legal action for additional damages
Seller Withdrawal Consequences
If seller withdraws post-exchange: must return deposit plus potential liability for buyer's additional costs and legal action
Actions Between Exchange & Completion
The period between exchange and completion requires careful coordination to ensure everything is ready for completion day. Both parties have specific responsibilities during this crucial timeframe.
For Buyers
For Sellers
Completion Day Process
Completion day represents the pinnacle of the property transaction process. On this day, legal ownership transfers from seller to buyer, funds are exchanged, and keys are handed over to complete the transaction.
Completion Day Timeline
Morning Preparations
Solicitors perform final checks, buyer's funds transferred to seller's solicitor account
Midday Completion
Legal ownership transfers, outstanding balance paid, property registration updated
Key Handover
Keys released to buyer, property access granted, moving can commence
Completion Day Logistics
Optimal Timing
- • Friday completion: Weekend moving time but Monday backup needed
- • Mid-week completion: More flexible but work day coordination required
- • Same-day exchange/completion: Fast but high-stress option
- • 1-4 week gap: Standard timeframe allowing proper preparation
Key Considerations
- • Higher Friday demand: Removal companies more expensive
- • Chain coordination: Multiple completions must synchronise
- • Fund availability: Bank transfers must clear on time
- • Backup planning: Contingencies for delays essential
