When taking a commercial lease, many tenants and landlords reach agreement on the main terms through an estate agent before solicitors are instructed. Rent, lease length, permitted use and other commercial points may already appear settled, leading some clients to wonder what role a solicitor plays once the deal is “agreed”.

In reality, agreeing commercial terms is only the starting point. The legal lease, not the negotiations, ultimately governs the relationship between landlord and tenant, often for many years.

From Agreement in Principle to Binding Contract

Estate agents commonly prepare heads of terms to record the commercial understanding between the parties. These documents are typically expressed to be “subject to contract”, meaning they are not legally binding.

The solicitor’s role is to convert those commercial intentions into a legally enforceable document that accurately reflects what has been agreed while protecting the client from unexpected risk.

This process involves far more than simply reviewing wording.

Ensuring the Lease Reflects the Deal

One of the most important tasks a solicitor undertakes is comparing the draft lease against the agreed commercial terms.

In practice, discrepancies frequently arise. For example:

  • repair obligations may be wider than anticipated;
  • service charge provisions may impose additional costs;
  • permitted use clauses may restrict how the property can operate;
  • incentives such as rent-free periods may be unclear or incomplete.

Even small drafting differences can have significant financial consequences over the life of a lease.

Identifying Risks Clients May Not Expect

Commercial leases are often lengthy and technical documents. Provisions relating to repair, insurance, alterations, assignment, and termination rights can create liabilities that are not obvious from heads of terms alone.

A solicitor’s role includes identifying risks that may not have been discussed during negotiations, explaining their practical impact, and negotiating amendments where appropriate.

This is particularly important for small businesses taking premises for the first time, where assumptions based on residential renting experience can lead to misunderstandings.

Why Communication Still Matters

Although solicitors review the lease carefully, they rely on the information provided to them. Discussions held informally during negotiations are not always fully recorded in heads of terms, and clients may place importance on points that were never formally documented.

Highlighting what matters most at an early stage allows the solicitor to ensure those expectations are properly reflected in the lease before completion.

More Than a Formality

Legal review is not simply an administrative step before signing. A well-drafted lease provides clarity, reduces the risk of disputes, and ensures both landlord and tenant understand their obligations from the outset.

Addressing issues before completion is almost always quicker and less costly than attempting to resolve disagreements once the lease has been signed.

Conclusion

Even where commercial terms appear agreed, the lease itself determines the legal and financial realities of the arrangement. A solicitor’s role is to translate agreement in principle into a document that protects the client’s interests and provides certainty for the future.

Early legal advice often allows potential issues to be identified and resolved before terms are finalised, helping transactions proceed more smoothly and with greater certainty for both parties.
