How to check the details of a prior deed or contract referenced in a new document
A reference to a prior deed is either accurate or it is a problem waiting to surface. There is no middle ground. Before drafting or completing any document that cites an earlier instrument—a transfer, a power of attorney, an earlier contract—the details need to be checked against the original, not from memory or from a case note.
Why references go wrong
Most errors in citing prior deeds do not come from carelessness. They come from working with second-hand information. The solicitor or conveyancer uses the deed number the client quoted, the date that appears on a scanned copy, or the party names as they were typed into the file months earlier. Each step away from the original document introduces a gap.
An inaccurate reference can delay registration at the land registry, invalidate a clause, or create genuine uncertainty about which instrument was intended. In some cases, a single digit wrong in a title number is enough for an application to be rejected.
What to check before incorporating the reference
There are four points to check. All four, not just the ones that seem most likely to be correct.
The instrument's identifying number or reference. A title number, deed number, or document reference must be copied from the original, not from the file summary. One digit out is enough to make the reference wrong.
The date of execution. The date to cite is the date the document was signed, not the date it was registered or the date it was returned to the client. If the deed was executed on the 3rd and registered on the 15th, the new document should cite the 3rd.
The parties. The names and identifying details of those who were party to the earlier instrument need to match what appears in their current identity documents. If there are variations—through marriage, a transcription error in the original, or a name change—that needs to be resolved before drafting, not after.
The scope and purpose of the prior instrument. A reference to "a power of attorney" that does not specify what it covers may be insufficient when the new deed relies on it to authorise an action. It is worth confirming that the scope of the earlier instrument is consistent with what the new one requires.
How to organise the check
The most practical approach is to assign verification to whoever has access to the original document, not to the fee earner who is drafting. If the original is held by another solicitor or at a different registry, it needs to be requested with enough lead time before completion.
When the original arrives—as a certified copy or a download from the registry—the check is carried out against that version, not against a summary or a previous draft. The four details are recorded in the matter file and compared, point by point, with what appears in the new document.
If the new document references several prior instruments, the check is structured as a list: one block per reference, with all four fields. The next one does not begin until the previous one is complete.
When the original is not available before completion
There are situations where the earlier instrument cannot be obtained in time. In those cases, the reference should be marked as provisional, subject to a clause making it conditional on confirmation, or completion should be deferred.
What should not happen is incorporating a reference based on what someone recalls, in the hope that it is correct. An inaccurate reference in an executed document is considerably harder to fix than a delayed completion.
What to do when a discrepancy is found
If the check reveals that the details in the original do not match what has been recorded in the matter file, the correct version needs to be established before proceeding. The original is always the authority: if the original shows one date and the file shows another, work from the original and investigate where the file error came from.
If the discrepancy relates to a party's identifying details—for example, a name spelled differently across documents—the fee earner needs to determine whether it is a transcription error or a genuine change. The answer affects how the reference is drafted.
Recording the check in the matter file
Once the four points have been verified, the outcome goes into the matter file before drafting continues. This does not need to be a formal record: a brief note against each reference is enough—what was checked, where the original was sourced, and the date of the check.
This matters most when a transaction passes through more than one person. If the fee earner who checked the prior deed is not the one who drafts the final document, a note in the file means the next person does not have to repeat the check or assume it was done.
It also matters when closing the file. A verifiable record of which prior instruments were checked, and when, is easier to locate at the end of a matter than a memory of having done it.
