So, you’ve agreed terms for a commercial property deal. The mood is buoyant. Any previously felt frustration disappears. Timescales once described as “indicative” start being treated as if they’re pencilled into the diary. Someone suggests a completion date with a straight face. Another comments, “I don’t think there’s anything controversial left now.” We’re all on the same page and good to go.
Heads of Terms: Establishing the Commercial Framework
Heads of Terms are the point in a property deal where everyone is at their most aligned. The square footage works, the rent makes sense, the incentives have done their job, and so on. The commercial shape of the deal is clear. That alignment is key. If you don’t get this part broadly right, nothing that follows really works.
Why Heads of Terms Can’t Cover Every Detail
However, Heads are deliberately optimistic documents. They capture what everyone is trying to achieve with a real, physical asset, assuming sensible behaviour, a workable timetable, the availability of both people and materials, and, generally, that the planets will align. This isn’t naïve. It’s practical. If Heads of Terms tried to wrestle every possible property‑specific risk to the ground at this stage, most transactions would stall before anyone had ordered a floor plan. Compromises are made, detail is left for later, and certain questions are allowed to sit quietly to one side.
The difficulty is that commercial property has a habit of moving from theory to practice very quickly. A contract or lease doesn’t live on paper for long before it needs to work in practice alongside contractors, surveyors, funders, insurers, and the inconvenient reality that an optimistic timetable isn’t always the cure for delays outside anyone’s control.
The moment Heads of Terms start turning into leases, agreements for lease or supplemental documents, the questions change. Not “are we comfortable in principle?” but “how does this actually work once they’re in occupation?”
The Role of Lawyers in Commercial Property Transactions
As lawyers, whose role is to reflect the parties’ intentions within the framework of the law, we ask the questions that allow us to cover the detail:
“How long a period to you need for this?”, “Can we just sanity‑check this payment mechanism?”, “How does that interact with the service charge?”, “What happens if the fit‑out overruns?”, “What was intended with the rent review?” and “What are the financial implications?”
From the outside, this can look like complexity is being introduced. In reality, it’s complexity turning up late to the party, having missed the welcome drinks where the deal was launched. Commercial property transactions are full of assumptions – access, repair, alterations, handover condition and timing. They all worked perfectly well at Heads stage but now need to be tested.
This is where lawyers turn to the detail, not to reopen the commercial bargain, but to take what was agreed in outline and work out how it survives beyond the “in principle” discussions, and how it sits alongside the title, the building, and the next several years of use.
The questions we ask weren’t ignored earlier. They were simply awaiting their turn.
That middle stretch of a property transaction – after Heads, before signature – is rarely anyone’s favourite part (although us lawyers tend to enjoy getting to grips with the legal detail!). It’s where enthusiasm gives way to practicality, and where a deal stops being aspirational and starts being operational.
Handled as a normal part of the process, it’s simply the sound of the deal settling into place. Handled as a surprise, it can feel as though the transaction has suddenly developed opinions of its own.
A well‑prepared set of Heads of Terms doesn’t remove this stage. It just makes it more predictable. The more clearly the commercial intentions are captured at the outset, the easier it is to translate them into something that works in practice.
Seen in that light, that “middle stretch” isn’t a hurdle but a necessary transition. It’s where a shared intention becomes something robust enough to withstand the reality of occupation.
Get the foundations right, expect the detail, and – working with advisers who can translate the commercial intention into something that functions in practice – the process works as it should: not as an obstacle, but as the mechanism that turns agreement into something that works long after the ink has dried.
The earlier that process is understood and engaged with, the smoother it tends to be. That’s where legal input adds real value – not by changing the deal, but by helping ensure it delivers what was intended when Heads were first agreed.
