A matrimonial valuation is not a stronger opinion than the one an estate agent will give you for free. It is a different kind of document, produced for a different audience, and the difference is the whole point. In family proceedings the court will only allow expert evidence at all where it considers that evidence necessary to assist the court to resolve the proceedings.
That single line changes how the figure has to be built. It has to be defensible, methodical and traceable to evidence, because it may end up in front of a judge who is entitled to ask how it was reached.
Quick answer: A matrimonial valuation is a formal, written market valuation of a property produced by an RICS Registered Valuer for use in divorce or separation proceedings. It states a defined basis of value at a defined date, sets out the evidence behind the figure, and is prepared so that both parties and the court can rely on it.
What a matrimonial valuation actually is
Most of the assets in a separation are easy to value. A bank balance is a number. A pension has a statement. The house is the one asset where two people can hold honestly different beliefs about what it is worth, and where the difference between those beliefs is often the largest single figure in the settlement.
The job of the valuation is to remove that argument, not to win it for anybody. A valuer instructed in a matrimonial context produces a written report that states the property’s market value on a stated date, on a stated basis, with the comparable evidence and the reasoning visible.
Our valuations are prepared under RICS Valuation – Global Standards, the framework the profession refers to as the Red Book. That is what makes the report a professional product with a named, regulated author behind it rather than a marketing estimate.
Why an estate agent appraisal is not the same thing
This is the point people ring us about most. An agent will happily give you a figure, it costs nothing, and it arrives the same week. So why pay for a formal valuation at all?
Because the two documents are made for different purposes. An agent is estimating an asking price with a view to being instructed to sell. A valuer is stating an opinion of value they can be held to.
| Estate agent appraisal | RICS valuation report | |
|---|---|---|
| Purpose | To win the instruction and set an asking price | To state an opinion of value that can be relied on |
| Author | Agent or valuation lister | Named RICS Registered Valuer |
| Basis | Rarely defined | Defined basis and valuation date, stated in the report |
| Evidence | Usually not disclosed | Comparable evidence set out and reasoned |
| Accountability | None to the other party | Regulated, professionally insured, and open to challenge |
None of that makes agents wrong. It makes their document the wrong tool for this job. Where the two parties already agree on a figure, an agent’s view may be all that is needed. Where they do not, an appraisal tends to be met with a competing appraisal, and you are no further forward.
The single joint expert arrangement
Rather than each side instructing its own valuer, family proceedings commonly use a single expert instructed by both parties together. The Family Procedure Rules give the court power to direct that expert evidence be given by a single joint expert, and define that expert as one providing evidence on behalf of two or more of the parties.
In practice this is usually the cheaper and calmer route. There is one inspection, one fee split between the parties, and one figure on the table rather than two figures and an argument about the gap between them.
It also changes the relationship. A single joint expert is not acting for the person who happened to make the call. Instructions come from both sides, the report goes to both sides at the same time, and questions are put in writing where either party wants something clarified. If you are used to instructing professionals who act for you alone, that takes a moment to get used to, and it is exactly what makes the figure usable.
What the valuer looks at
The inspection is thorough but proportionate. We are not producing a condition report, so this is not a survey; the purpose is to arrive at a value and evidence it.
- The property itself — accommodation, floor area, layout, plot, parking, outbuildings, aspect and general condition.
- Anything that materially affects value — extensions, structural alterations, obvious defects, or work that has clearly been carried out without the paperwork to support it.
- Legal and title factors — tenure, lease length where relevant, service charges, rights of way, and anything disclosed that a buyer would take into account.
- Comparable evidence — recent completed sales of genuinely similar properties in the same market, adjusted for the differences between them and the subject property.
- The market at the valuation date — because the figure is stated as at a date, not as a general impression of the year.
That last point causes more confusion than any other. A valuation is a photograph, not a film. It speaks as at the date given on its front page.
Timescales, and what usually holds things up
The inspection itself takes an hour or two for a typical house. The report follows once the comparable evidence has been researched and analysed properly, which is the part that takes the time and the part that makes the report worth having.
What delays matters is almost never the surveying. It is access, agreement and paperwork.
- Agreeing the instruction — where the valuer is acting for both parties, both solicitors usually need to sign off the letter of instruction before anything is booked.
- Arranging access — where one party is living in the property and the other is not, this can take longer to fix than everything else combined.
- Missing documents — a lease, planning consent or building regulations certificate that nobody can lay hands on.
- Unusual property — a converted barn, an annexe, land with development potential, or anything where the comparable evidence has to be worked harder.
What most guides on this get wrong
Search the subject and you will be told, repeatedly, to get three valuations and take an average. It sounds fair. It is not analysis, and it does not survive scrutiny.
Averaging three numbers assumes all three were produced to the same standard, on the same basis, at the same date, with the same information. They almost never are. Averaging a high asking-price estimate with a cautious one produces a fourth number that nobody has taken responsibility for and that nobody can explain.
The alternative is one properly evidenced figure that both sides can interrogate. If a party disagrees with it, there is a mechanism: ask the valuer written questions about the basis, the comparables or the adjustments. Disagreement with a reasoned report is answerable. Disagreement with an average is not.
Where a valuation sits alongside other property advice
Separation sometimes throws up more than a value. A property may have a defect that affects what it is worth, a boundary that has never been resolved, or a dispute that needs a formal opinion for the court. Those are separate pieces of work.
If the question is purely what is it worth, a valuation answers it. If the question is what is wrong with it, that is a survey. And where a matter needs formal evidence in proceedings, that is the territory of an expert witness surveyor rather than a valuation report. It is worth being clear at the outset which of the three you actually need, because instructing the wrong one costs time you may not have.
If you want the background on how valuation differs from survey work in general terms, we have set that out in our guide to how a valuation differs from a home survey, and in our explainer on what a house valuation actually involves.
Need a valuation both sides can rely on?
We are RICS Registered Valuers based in Lincoln, and we carry out formal property valuations for separating couples and their solicitors across Lincoln, Lincolnshire, Nottinghamshire and the surrounding counties. Joint instructions welcome.
Who pays for a property valuation in a divorce?
Where the valuer is instructed jointly, the fee is usually split equally between the parties, though the parties or their solicitors can agree a different split. Where each side instructs separately, each side pays for its own report. Your solicitor will normally confirm the arrangement in the letter of instruction.
Can we just use an estate agent valuation for divorce?
If both parties genuinely agree the figure, an agent’s view may be enough for a negotiated settlement. If the figure is contested, or if the matter may go before a court, an agent’s appraisal is unlikely to carry the same weight as a formal report by a named RICS Registered Valuer setting out its basis and evidence.
What is a single joint expert?
A single joint expert is one expert instructed on behalf of two or more parties rather than by one side alone. The Family Procedure Rules define the role and give the court power to direct that evidence be given this way. In property terms it means one inspection, one report, and one figure sent to both parties at once.
How long is a matrimonial valuation valid for?
A valuation states value as at a specific date, so strictly it does not expire, it simply becomes historic. Where proceedings run on and the market moves, parties often ask the valuer to review or update the figure at a later date rather than start again from scratch.
Can I challenge a valuation I disagree with?
Yes. The usual route is to put written questions to the valuer about the basis of value, the comparable evidence relied on, or the adjustments made, rather than commissioning a rival figure. A reasoned report can be tested; that is one of the reasons for having one.
