A retrospective valuation asks what a specified property interest was worth at an earlier date. In separation or divorce matters, the relevant date may be set by agreement, legal advice or a court direction. The surveyor must not assume that today’s value, adjusted by a broad index, gives the correct historic answer.
The instruction should define the date, interest, purpose and users precisely. If the report is intended as expert evidence, the solicitors must also confirm the procedural requirements and whether a single joint expert is required.
Reconstructing the earlier property
A current inspection helps the valuer understand the building, but the property may have changed. Extensions, refurbishment, disrepair, lease events or changes of occupation after the valuation date must be identified.
Contemporaneous photographs, sales particulars, plans, invoices, tenancy agreements and planning records can provide a more reliable picture. Where evidence conflicts, the valuer should explain the adopted assumption.
Historic market evidence
The valuer researches transactions relevant to the historic date and analyses their property and transaction characteristics. Later evidence may sometimes illuminate the earlier market, but it must be treated carefully and not introduce hindsight that buyers and sellers did not possess.
Published indices can provide context, yet they describe market trends across groups of properties. They do not capture the precise condition, lease, setting and purchaser demand for one home.
Facts that need legal confirmation
The surveyor values the interest instructed. They do not decide beneficial ownership, whether a transfer occurred on a particular date or which matrimonial assets should be included. Those questions should be resolved or framed by the parties’ lawyers.
If the factual position is unresolved, the instruction may ask for alternative valuations under expressly stated assumptions. That is preferable to concealing uncertainty in one figure.
Report use and limitations
The report should distinguish the valuation date, inspection date and report date. It should identify evidence, assumptions, limitations and any material uncertainty. The conclusion applies only to the stated users and purpose.
A retrospective valuation is not legal or tax advice and cannot guarantee adoption in negotiations or proceedings.
Allow more preparation time than for a straightforward current valuation. Historic evidence may need to be requested from agents, solicitors, occupiers or public records and its reliability checked. Agreeing an accurate property chronology first can reduce duplicated research and expose factual disagreements that the legal advisers need to resolve before reporting.
- Confirm the exact historic date
- Create a chronology of physical and legal changes
- Provide contemporaneous photographs and documents
- Ask solicitors to approve the instruction and assumptions
