When Do You Need a Sworn Property Expert?
The difference between an ordinary valuation and a sworn expert's report, and when an independent report becomes necessary before a court, a bank, or in a dispute or estate division.
Not every question about what a property is worth needs an expert report. Sometimes a preliminary view is enough. But there are situations where nothing substitutes for an independent report.
What "sworn expert" means
A sworn expert is a technical specialist instructed to carry out expert work, whose opinion must rest on grounds set out in the report. The Ministry of Justice provides that an expert's report must state the conclusion, the opinion, and the basis relied on.
The status is not a marketing title. It is a professional framework with obligations attached, independence first among them.
When a preliminary view is enough
- You want a general sense of your property's value before thinking about selling.
- You are comparing two investment options at a preliminary stage.
- You want to know whether a price you have been offered is broadly sensible before going further.
In these cases, a conversation may be all you need.
When an independent report becomes necessary
Before a court
Where proceedings involve a technical question about a property's value or characteristics — whether the court appoints an expert or a party commissions an independent report.
A number will not do here. The report has to withstand reading by an opponent looking for a gap, and by a judge asking: on what basis?
Before a bank
Where a property is offered as security or a financing file is under review. Banks require reports meeting their own conditions and do not accept general estimates.
In a dispute between co-owners or heirs
Where each side's interest runs the opposite way, an estimate produced by one of them is worth nothing. The other side will not accept it, and rightly so.
An independent report is useful precisely because it does not come from either party.
In dividing an estate
Especially where the estate holds properties of different types. Comparing them requires a single measure.
Before an embassy or authority
Where a formal file requires proof of an asset's value.
What distinguishes an expert's report
Independence. The expert does not act for whoever pays the fee. If they did, the report would lose all of its worth.
Stated grounds. The report shows what was reviewed, what was observed, and which approach was used and why. A bare number can be rejected; a reasoned number can be discussed.
Date and purpose. Every value is tied to its date and to the purpose it was prepared for.
Clear limits. A good report also states what it did not cover, and what assumptions it rests on.
What an expert does not do
Give legal opinion, resolve a dispute, determine inheritance shares, or guarantee that any institution will accept the report.
Nor exceed the instruction. Where a file needs a surveyor, engineer, lawyer or accountant, that is said rather than stepped over.
How to choose
Ask three things: will you inspect the property? Which documents will you need? And will the report explain your approach, or just give me a figure?
The answer to the third usually tells you whether you are looking at a report or at an estimate in a cover.
