If your solicitor, mortgage lender, or their panel firm has asked you to obtain a "disponor letter", you may have searched the term and found very little clear information. That is because disponor letter is an informal name — widely used in the conveyancing industry — for a very specific legal document: the Certificate of Compliance required to satisfy a Form LL Fraud Restriction on your property title.
This page explains exactly what a disponor letter is, why you need one, who can issue it, and how FormLL can get one into your inbox in days.
A disponor is the legal term for the person who transfers or conveys a property interest to another party. In a sale, the seller is the disponor. In a remortgage, the property owner executing the mortgage deed is the disponor. The word comes directly from the formal wording of the Form LL restriction itself.
When a Form LL restriction is on your title register, it prevents any transaction from being registered at Land Registry until a solicitor certifies — in a signed letter — that the disponor (you, executing the documents) is genuinely the same person as the registered proprietor. That signed letter is what people call a disponor letter.
This is one of the reasons people find this so confusing. The same document is referred to by multiple names depending on who you are speaking to:
Regardless of what it is called, it is the same document with the same prescribed wording, issued by the same type of independent solicitor, for the same purpose.
The core wording is prescribed by Land Registry and must appear in the certificate. It reads:
The letter is signed with a wet ink signature by the issuing solicitor. It is then scanned and emailed directly to you. You pass it to your transaction solicitor, who includes it in the Land Registry application.
Some lenders — particularly those using panel firms such as Optima Legal or Integra — may require additional specific wording beyond the standard prescribed text. If your lender has specified particular wording requirements, make sure to communicate this when booking.
The disponor letter must be issued by an independent SRA-regulated solicitor. This is the critical point that catches most people out:
This is why most people get stuck. Their remortgage solicitor tells them they need a disponor letter but cannot provide one themselves. Finding an independent specialist who handles this work is not straightforward — most general conveyancing firms rarely encounter it and either decline or waste your time attempting it before referring you on.
The process takes place via a short video call. You will need:
The call itself typically takes around 15 minutes. Once the solicitor is satisfied with the verification, they issue the letter the same day or next working day.

Get Your Disponor Letter — £160Yes. A disponor letter is an informal industry name for the Certificate of Compliance required to satisfy a Form LL Fraud Restriction. The terms are used interchangeably. The document itself has prescribed wording set by Land Registry and must be signed by an independent, SRA-regulated solicitor.
Yes. Form LL verification, disponor letter, Certificate of Compliance, and anti-fraud restriction certificate all refer to the same document and the same process. The terminology varies between firms and lenders but the requirement is identical.
No. A disponor letter satisfies the restriction for a specific transaction — your current sale or remortgage. The restriction remains on your title register and will need to be satisfied again for any future transaction. If you want the restriction removed permanently, that is a separate Land Registry application and a different process entirely.
Both registered owners must be present on the same video call and both must be verified before the disponor letter can be issued. An additional fee of £50 inc VAT applies per additional owner. Both owners must attend the same call — individual separate calls attract an additional charge of £100 inc VAT per person.

A disponor letter is drafted for a specific transaction and does not carry a formal expiry date. However, if the transaction it was issued for does not proceed and you restart with new documents (for example, a new mortgage offer), you will likely need a fresh letter as the transaction details will have changed.
