Why has the developer's solicitor written to me?

When the letter about your right to light comes from a law firm rather than a surveyor, the developer is telling you something without saying it: there is a legal budget behind this scheme, the paperwork is being built to withstand a dispute, and your claim has moved from a line in a spreadsheet to a file with a fee earner's name on it.

• A solicitor's letter is the formal channel. Surveyors assess and negotiate; solicitors paper the outcome, in the form of deeds of release, notices, and the record that will matter if the dispute ever reaches court.
• Two technical references demand immediate attention if they appear: a light obstruction notice (LON) and section 203. Both change your position, and one carries a statutory clock.
• You are entitled to take legal advice before responding, and arranged the right way, that advice costs you nothing unless you win. Check your claim.

Why has the developer's solicitor written to me?

Usually for one of four reasons. To formalise an offer a surveyor has already floated, now attached to a deed of release drafted for signature. To open contact on schemes where the developer wants the record managed by lawyers from the outset, which is common on larger or insured projects. To serve or notify you of formal steps, such as a light obstruction notice. Or to respond to something you did: perhaps you objected to planning, wrote to the developer, or declined a surveyor's approach. In each case the letter is doing double duty, communicating with you while building a paper trail showing the developer behaved reasonably if a judge ever reads the file. Your replies join that same record, which is why what you put in writing now matters.

Is this letter a legal threat?

Probably not yet, and the distinction is worth understanding because it cuts both ways. A letter from a developer's surveyor, however firm its tone, carries no legal force as a threat: surveyors cannot issue proceedings, and their correspondence is commercial negotiation. A letter from a solicitor sits closer to the machinery. It can precede formal steps and its contents are drafted with litigation in mind, but an introductory or settlement letter is still negotiation, not a claim. The same logic applies in reverse, and it is the part developers rarely volunteer: letters from a neighbour only carry weight when the developer's team believes legal proceedings could genuinely follow. An objection with nothing behind it, however heartfelt, is priced as noise. A claim with solicitors engaged and the costs risk covered is priced as risk.

What if the letter mentions a light obstruction notice (LON)?

Treat this as the urgent variant. Under the Rights of Light Act 1959, a developer can register a notional obstruction of your light as a local land charge. No hoarding is built; the obstruction exists on paper. Its purpose is to interrupt or defeat rights of light that are still being acquired by long enjoyment under the Prescription Act 1832. If you take no action while the notice stands, rights your windows were close to securing can be lost, and the developer's position hardens permanently. A LON can be challenged, but the window for doing so effectively is limited. This is the one letter where "deal with it next month" is a genuinely costly decision. You can check what is registered against your property through the local land charges register.

What if the letter mentions section 203?

Section 203 of the Housing and Planning Act 2016 allows rights of light to be overridden where land has been appropriated or acquired by a local authority for planning purposes, converting your injunction claim into a right to statutory compensation only. It is a powerful provision, but a narrow one: it belongs to council-backed regeneration schemes, not to the typical private development. If a letter invokes it, two questions follow immediately. Does section 203 genuinely apply to this land and this scheme? And is the developer using its shadow to discourage a claim it cannot actually extinguish? Both are questions for an independent specialist solicitor, not for the firm that wrote the letter.

Do I need my own solicitor, and who pays?

You need independent advice before any substantive response; whether you pay for it is a separate question. Instructing a property litigation solicitor privately means hourly rates, expert surveyor fees on top, and, if matters escalate, exposure to the other side's costs if you lose. A no win, no fee deal with a solicitor may cover some of their own fees, but ask precisely what happens to the expert fees, the court fees and the other side's costs, because the answer is often "still yours." The Daylight Protect Claim Plan works differently: specialist solicitors act for you no win, no fee, insurance included in the plan pays the expert bills, the court fees and the developer's costs if the claim fails, and our fee is a percentage paid only out of a successful recovery. All of it is set out in writing before your case begins, and there is nothing for you to pay if the claim is unsuccessful. The full comparison: claims company vs your own surveyor vs solicitor.

Frequently asked questions

Should I reply to the solicitor myself?

Keep any holding reply minimal: acknowledge receipt, say you are taking advice, commit to nothing. Substantive points, such as your property's history, your view of the impact, or any figure, should wait until someone independent has assessed your position, because everything you write enters the file.

The letter gives me 14 days. Is that real?

A negotiating deadline and a statutory one look identical on the page. Deadlines attached to offers are usually pressure; deadlines connected to a LON or formal process can be real. Have the letter read by someone qualified before the date, not after.

Does a solicitor's letter mean they'll sue me?

Developers almost never sue neighbours over rights of light. The risk runs the other way, which is the entire reason you are being written to. The letter is about extinguishing your claim against them, on terms set before you knew what it was worth.
