What Is a House Contract?
A house contract, also known as a contract for sale, is a written agreement between the buyer and seller of a property. It defines the key terms of the transaction, including:
- Description and address of the property
- Price agreed by both parties
- Deposit amount
- Completion date
- Special conditions or contingencies
The contract becomes legally binding once both parties sign and exchange contracts. Until that point, either party may withdraw from the deal without penalty.
The Conveyancing Process: An Overview
The signing of the contract is a critical point in the wider conveyancing process, which refers to the legal and administrative work involved in transferring property ownership.
Stages of the Process Include:
- Instructing a solicitor or conveyancer
- Pre-contract enquiries and searches
- Drafting and reviewing the contract
- Agreeing on completion terms
- Signing and exchanging contracts
- Completion of the sale
- Post-completion formalities (e.g. registration and stamp duty)
Blackstone Solicitors supports both buyers and sellers at every step, ensuring legal compliance, transparency, and efficient progress.
Instructing Legal Representation
Once the decision to buy or sell a property has been made, both parties should instruct a solicitor or licensed conveyancer. This legal professional will:
- Verify identity and carry out anti-money laundering checks
- Review and draft legal documentation
- Communicate with the other party’s solicitor
- Manage funds and complete registration
Early engagement with a solicitor can identify potential obstacles and minimise delays.
Property Searches and Enquiries
Before signing the house contract, the buyer’s solicitor will carry out essential searches and enquiries. These investigate legal, planning, and environmental factors that may affect the property.
Common Searches Include:
- Local authority search: Information on planning, building regulations, and highways
- Environmental search: Identifies risks of flooding or contamination
- Water and drainage search: Confirms connections and responsibilities
- Land Registry search: Verifies legal ownership and any registered interests
Additional enquiries may be raised regarding boundaries, warranties, and fixtures. The seller must respond via their solicitor and provide supporting documentation (e.g. energy performance certificate, property information forms, and fittings and contents list).
Drafting the Contract
The seller’s solicitor is usually responsible for drafting the contract for sale, based on the terms agreed between the parties. This includes:
- Details of buyer and seller
- Property description and title information
- Purchase price and deposit
- Proposed completion date
- Rights, restrictions, and covenants (if applicable)
- Fixtures and fittings included in the sale
- Any special conditions (e.g. subject to mortgage approval)
The buyer’s solicitor will review the draft contract and raise queries or suggest amendments to protect their client’s interests.
Mortgage Arrangements
If the buyer requires a mortgage, the lender will conduct a valuation of the property and issue a formal mortgage offer. The buyer’s solicitor must check the terms, ensure sufficient funds are available, and prepare a report on title for the lender before contracts can be signed.
At Blackstone Solicitors, we work closely with mortgage lenders to fulfil their legal requirements and facilitate timely funding.
Signing the Contract
Once all enquiries are resolved, searches completed, and the buyer’s funding is confirmed, both parties will sign their copies of the contract.
- Each party signs their own duplicate
- Signatures are usually witnessed
- Contracts are held by solicitors pending exchange
Despite signing, the deal is not legally binding until exchange of contracts takes place.
Exchange of Contracts
The exchange is the pivotal legal moment in the house-buying process. It involves both parties’ solicitors swapping signed contracts and confirming the deal.
Once exchanged:
- Both parties are legally bound to complete
- The buyer pays the agreed deposit (usually 10% of the purchase price)
- A completion date becomes fixed
- Penalties may apply if either party fails to complete
Exchange can take place in person, via post, or by telephone between solicitors. It is crucial that both parties are ready, funds are in place, and all conditions have been satisfied.
Deposit Payment
The buyer must pay the deposit on exchange. This secures the property and confirms commitment. If the buyer pulls out after exchange, the deposit may be forfeited.
In certain cases—such as new-build purchases or auctions—the deposit structure may vary. At Blackstone Solicitors, we ensure deposit terms are clearly outlined and protected.
Completion of the Sale
Completion refers to the point at which the property legally transfers to the buyer. It typically occurs:
- On the date specified in the contract
- After all funds are transferred to the seller’s solicitor
- Following confirmation that the transaction is complete
Once completed:
- The buyer receives the keys
- The seller vacates the property
- Legal ownership changes hands
Blackstone Solicitors manages the financial and legal processes involved in completion, providing reassurance and clarity throughout.
Post-Completion Formalities
After completion, the buyer’s solicitor attends to several post-transaction duties:
- Registering the property with HM Land Registry
- Paying Stamp Duty Land Tax (SDLT) where applicable
- Notifying mortgage lender of registration
- Safekeeping of title documents
Registration confirms legal ownership and protects the buyer from third-party claims. Prompt submission avoids penalties and delays.
Common Issues and Pitfalls
House contracts can be delayed or complicated by:
- Title defects (e.g. unregistered land or boundary disputes)
- Missing planning permissions or building regulations approval
- Failure to obtain mortgage offer in time
- Problems revealed in searches (e.g. environmental risks)
- Chain delays where multiple properties are involved
Blackstone Solicitors identifies and resolves potential issues early, offering pragmatic advice and robust representation.
Tips for a Smooth Transaction
To ensure a seamless contract-signing process:
- Instruct a solicitor promptly and provide requested documents
- Be responsive and transparent about property condition or history
- Ensure funding is arranged early
- Read all documentation carefully before signing
- Seek professional advice if uncertain
Property transactions are complex, but with experienced legal support they can proceed smoothly and efficiently.
