The Lease Had 77 Years Left. The Warning Never Came.

A buyer completed with 77 years left on the lease. The lease term appeared in the papers, but its significance was not explained. More than two decades later, a purchaser required the lease to be extended and the owner paid a £45,000 premium. A Legal Ombudsman Final Decision dated 20 May 2025 concluded that the original conveyancer should have given meaningful advice before the purchase completed.

The resulting remedy was £34,900. The figure is striking, but the central lesson is not simply that lease extensions can be expensive. It is that recording the term of a lease is not the same as advising the buyer what that term could mean.

The buyer was told the original term, not the practical risk

The property was held under a lease originally granted for 99 years. At the time of the purchase, approximately 77 years remained.

There was no evidence that the buyer received advice before completion about the diminishing term, the possible effect on value, the availability and likely cost of a lease extension, or the consequences for a future sale or mortgage.

A Report on Title was sent approximately seven months after completion. It referred to the original 99 year term and its commencement date, but it did not calculate the years remaining or explain why that calculation mattered. By then, the opportunity to use the advice to inform the purchase had already passed.

This illustrates the distinction explored in our article, The Client Signed the Report on Title. But Did They Understand It? A report should support an informed decision before commitment. It should not merely preserve facts on the file, particularly if it arrives after completion.

The failure was not arithmetic. It was the loss of choice

The unexpired term could be calculated from the lease. The professional task was to connect that figure with the decisions facing the buyer.

On the historic facts considered by the Ombudsman, proper advice could have allowed the buyer to:

• decide not to proceed with the purchase;
• seek a reduction in the purchase price to reflect the lease position;
• budget for an extension and decide when to obtain specialist valuation and legal advice; or
• ask the seller to serve the statutory notice then required so that the benefit could be assigned and the extension pursued without the buyer first waiting for the historic ownership period to expire.

The Ombudsman considered that, if properly advised, the buyer would most probably have proceeded with a lease extension at the time. Using historic valuation information, the likely premium was assessed at a midpoint of £10,500. The owner later paid £45,000. The difference of £34,500 was treated as financial loss, with a further £400 awarded for the emotional impact.

The legal costs of the eventual extension were not included because costs would also have been incurred if the extension had been completed earlier. The remedy focused on the additional premium attributed to the lost opportunity.

A mortgage offer did not answer the buyer’s question

The owner later remortgaged when approximately 73 years remained. That lender was apparently prepared to lend. The Ombudsman did not regard this as correcting the original failure or breaking the chain of events.

The remortgage conveyancers were acting for the lender, not advising the owner about whether and when to extend the lease. More fundamentally, acceptance by one lender does not establish that the lease presents no wider difficulty. The lender is deciding whether the property satisfies its own security requirements. The buyer needs advice about ownership, value, future mortgageability and practical marketability.

Those questions can diverge. A lease may satisfy the particular lender involved in a transaction while reducing the range of lenders available to a later purchaser. A conveyancer reporting to the buyer should therefore avoid treating the current mortgage offer as a substitute for advice about the buyer’s longer term position.

This decision does not mean that waiting is always more expensive

The Final Decision concerned a purchase completed many years earlier and assessed the advice against the legal and valuation framework relevant to that transaction. It should not be converted into a universal rule that every buyer with a short lease must extend immediately.

Lease extension legislation and valuation rules can change. Reform may alter the routes available, qualifying conditions, premium calculation and the relative advantages of acting now or waiting. An informal offer from a freeholder may also contain new ground rent, costs or other terms that require careful comparison with the statutory route.

The lasting lesson is about informed choice. The conveyancer should identify the actual unexpired term, explain the law and options applying at the time, recommend specialist advice where appropriate and record the client’s decision. The advice should be current, property specific and delivered while the buyer still has meaningful choices.

What should short lease advice cover?

The content will depend on the transaction, the law then in force and the scope of the retainer. A useful report will usually address:

• the lease commencement date, original term and precise unexpired term;
• why the remaining term may affect valuation, mortgage availability and resale;
• the current statutory and informal extension routes, without presenting either as automatically preferable;
• whether action by the seller before completion could preserve or improve an available route;
• the need for specialist valuation and lease extension advice;
• the possible premium, professional costs, timescale and procedural risk;
• any relevant ground rent or other proposed lease terms;
• the current lender’s requirements and the possible position across the wider mortgage market; and
• the choices available to the buyer before exchange, including renegotiation or withdrawal.

A threshold can operate as a useful warning trigger, but it should not replace judgement. The decision records the Ombudsman’s view that detailed advice was expected where 85 years or less remained in the circumstances considered. That is not the same as declaring 85 years to be a universal statutory deadline. The applicable law, lender requirements, valuation evidence and the buyer’s plans must all be considered.

Timing is part of the advice

Accurate advice delivered after completion cannot help the buyer decide whether to exchange. If a material issue is identified late, the conveyancer should explain what has changed and allow the client a genuine opportunity to consider the options.

This does not require every lease provision to become a lengthy lecture. It requires prominence and explanation proportionate to the risk. A buyer should not have to calculate the remaining term from two dates and then independently discover why the result matters.

Firms may also wish to review our earlier article on managing client expectations in conveyancing. Clear advice about cost, timing and uncertainty can prevent the client from leaving completion with an assumption that the lease requires no further attention.

When the problem only emerges years later

A short lease problem often remains hidden until the owner tries to sell or remortgage. A new lender, valuer or buyer then asks for an extension, and the owner begins to question what was explained during the original purchase.

The starting evidence may include the lease, register, purchase Report on Title, valuation, enquiries, attendance notes and correspondence about a possible extension. The question is not simply whether the lease term appeared somewhere in the file. It is whether the buyer was told what it meant and what could be done about it before becoming committed.

Historical lender requirements may form part of the evidence

If the purchase took place years ago, today’s lender instructions cannot establish what the buyer’s lender required at that time. Lender specific requirements change and superseded wording can disappear from public view.

The buyer’s lender instructions and the advice owed to the buyer are separate questions. Historic instructions may help establish whether the lender imposed a minimum term or reporting requirement. They do not define the whole duty to explain the effect of the lease to the client.

Lease extension work must also be completed properly

Giving appropriate advice at purchase is only the first control point. If an extension is later agreed, the documentation and registration must be completed and monitored. Our separate case study, Lease Extension Not Registered: A £48,957 Short Lease Warning, shows how an extension that was not registered prevented a later remortgage and generated a substantial remedy.

Together, the two decisions expose opposite ends of the same risk. In one, the buyer lost the chance to make an informed decision about extending. In the other, the client decided to extend but the post completion work was not brought to a successful conclusion.

The file should show the decision, not merely the lease

A defensible file should allow another reader to understand the advice in context. It should show the term calculated, the practical consequences explained, the routes and uncertainties discussed, any specialist advice recommended and the buyer’s informed response.

The fact that the lease was available to read is not enough. The fact that one lender agreed to lend is not enough. The fact that a Report on Title was eventually sent is not enough. The professional value lies in explaining the significance of the information in time for the client to use it.
