Property valuation is often required as part of a divorce or separation. On the face of it, the question can seem relatively straightforward: what is the property worth?
In practice, matrimonial valuations can be some of the more complicated valuations we undertake.
There is also a human side to this work which should not be overlooked. As a child of divorced parents myself, I am conscious that we are usually inspecting someone's home at what may be a particularly difficult point in their life. There can be a substantial amount of money at stake and, unlike many other types of valuation, there will often be two people involved whose financial interests may point in different directions.
If the parties had already agreed on everything, of course, there would often be little need for an independent valuer in the first place.
Our role is therefore not to obtain the highest possible valuation for one party or the lowest possible valuation for the other. It is to provide an independent and properly evidenced opinion of value.
I sometimes joke that you know you have done a good matrimonial valuation when neither side is completely happy with it. We might receive a question from one party asking whether we properly considered an improvement they made, followed by a question from the other asking whether we noticed the blown double-glazed window in the back bedroom.
Those questions are understandable. But the surveyor's job is not to find a compromise figure somewhere between the two parties' expectations. It is to arrive at the valuation that the evidence supports.
In this guide
What is a matrimonial property valuation?
A matrimonial property valuation is an independent valuation of a property, usually required to assist with the financial arrangements arising from divorce or separation.
Although the term "matrimonial valuation" is widely used, the same principles can apply where an unmarried couple separates and requires an independent valuation of jointly owned property. Similar circumstances can also arise following the dissolution of a civil partnership.
Depending upon the circumstances, the valuation might be required by the parties themselves, their solicitors, a mediator or the court.
At Richard Russell Surveyors, our matrimonial and separation valuations are undertaken by RICS Registered Valuers in accordance with the applicable RICS Valuation – Global Standards, commonly known as the Red Book.
The Red Book establishes professional requirements for valuations, including independence, objectivity, terms of engagement, the valuation process and reporting.
This is different from asking an estate agent what they think a property could sell for.
An estate agent's market appraisal can be perfectly useful when somebody is considering selling their home. Indeed, where separating parties are in agreement, informal market appraisals may sometimes be sufficient for their purposes.
However, where an independent valuation is required for financial negotiations or court proceedings, a formal valuation by an appropriately qualified surveyor will often be more suitable.
A matrimonial valuation has a different purpose from a marketing appraisal. It provides an independent opinion of Market Value that can be explained and supported by appropriate market evidence.
How is a matrimonial valuer appointed?
There are several ways an instruction can reach us.
A common route is through solicitors. One party may obtain quotations from several appropriately qualified valuers, with those details then being provided to the other party or their solicitor so that an expert can be agreed.
We also receive instructions through mediators, and sometimes separating couples approach us directly because they have already agreed that an independent valuation is required.
Another common scenario is for just one party to contact us initially.
Where both parties will ultimately need to rely upon the valuation, we will normally suggest that they consider agreeing the appointment jointly before the valuation takes place.
There is a practical reason for this.
If one person independently chooses a valuer, commissions the report and pays for it without involving their former partner, there is a risk that the other party simply rejects the valuation or questions the appointment. The parties can then end up paying for another valuation and be no closer to resolving the issue.
Where appropriate, it is generally much cleaner for both parties to agree who is being appointed, agree the scope of the valuation and enter into the terms of engagement from the outset. The fee can then be divided between the parties in whatever way has been agreed.
Not every separation reaches court, however, and not every valuation arrives through solicitors. The appropriate process therefore depends upon the circumstances.
What is a Single Joint Expert matrimonial valuation?
Where a property valuation is required as expert evidence in financial remedy proceedings, the parties will often seek to agree the appointment of a Single Joint Expert (SJE).
Rather than each party appointing their own surveyor to produce competing valuations, a Single Joint Expert is instructed jointly to provide independent expert evidence.
In England and Wales, expert evidence in family proceedings is governed by Part 25 of the Family Procedure Rules and the associated Practice Directions.
Practice Direction 25D provides that, wherever possible, expert evidence in financial remedy proceedings should be obtained from a Single Joint Expert instructed by both or all parties.
Where expert evidence is to be put before the court, the court's permission is required. The appointment and instruction of an expert, and permission to rely upon that expert's evidence in proceedings, are distinct matters.
The expert's role is not to support either party's position. It is to provide an independent opinion within their area of expertise, with an overriding duty to assist the court.
This is an important distinction from a valuation privately commissioned by one party, even where that valuation has been undertaken by an RICS Registered Valuer.
A Red Book valuation and a court-compliant Single Joint Expert report are not necessarily interchangeable. The latter must also satisfy the applicable procedural requirements for expert evidence.
Who does the matrimonial valuer actually act for?
An independent valuer is not there to advocate for whichever party contacted them first, nor for the person who happens to be paying the invoice.
Where a surveyor is acting as an expert in family proceedings, Part 25 of the Family Procedure Rules makes clear that their duty to assist the court overrides any obligation to the person who instructed or paid them.
That independence also affects how we communicate.
Where we have been jointly instructed, substantive correspondence relating to the valuation should be transparent between the relevant parties. One party cannot privately provide information intended to influence the valuation without the other party being aware of it.
There may, of course, be entirely innocent reasons for somebody contacting us individually — arranging access, for example. But information relevant to the valuation itself needs to be dealt with appropriately.
Our job is not to decide who "deserves" a particular outcome. It is to value the property.
What happens during a matrimonial valuation?
The exact process depends upon the instruction, but a typical valuation involves:
Agreeing the scope and basis of the instruction.
Reviewing the relevant property documentation.
Inspecting the property.
Considering its accommodation, condition, location and other characteristics.
Researching appropriate comparable market evidence.
Analysing that evidence and arriving at an opinion of value.
Preparing the valuation report.
The inspection is an important part of the process, but it is only one part.
We are not simply walking around the house and deciding what it "feels" like it is worth. The property's characteristics have to be considered against relevant evidence from the market.
It is also important to understand that the inspection is a valuation inspection, not automatically a Building Survey. This distinction becomes particularly relevant where one or both parties are concerned about defects.
Do both parties need to attend the valuation?
No.
This is something we are asked about surprisingly often, particularly where the separation has been difficult and the parties do not want to be together.
There is no benefit in creating an uncomfortable situation unnecessarily.
Where the relationship is amicable enough, both parties can be present. We may ask factual questions about the property — alterations, extensions, dates of works or other matters relevant to our inspection — but we would not normally discuss our opinion of value with either party while we are there.
In other cases, both parties may attend the property but remain separately outside or in their respective vehicles while we undertake the inspection.
Sometimes the simplest arrangement is for neither party to be present. Access can be arranged and, if factual questions arise during the inspection, these can subsequently be put to the parties in writing.
The important thing is not whether both people physically stand in the house while we inspect it. It is that we have appropriate access, sufficient information and an independent process.
How does the condition of the property affect a matrimonial valuation?
This is an area where matrimonial valuations are sometimes misunderstood.
We occasionally receive an enquiry from somebody asking for a Building Survey, only for it to become apparent during the conversation that what they actually require is a matrimonial valuation.
Sometimes their thinking is understandable: if a surveyor can identify enough defects with the house, perhaps those defects can be used to justify a lower valuation.
That is not quite how market valuation works.
Condition absolutely can affect value. A house requiring substantial repairs may sell for less than an otherwise comparable house in good condition.
But the cost of repairs is not normally a figure that can simply be deducted pound-for-pound from the value of the property.
If a property requires £20,000 of work, it does not automatically follow that its Market Value is £20,000 lower.
The market might react by more than £20,000. It might react by less. In some circumstances the issue might make little measurable difference at all.
What matters is how the property's condition would influence the behaviour of market participants.
That is one of the fundamental differences between a Building Survey and a valuation.
A Building Survey is principally concerned with the condition of the building: what defects are present, their implications and what should be done about them.
A valuation asks a different question: what effect, if any, do those circumstances have upon the property's value?
What if there is uncertainty about a defect?
Sometimes the answer cannot responsibly be established without further information.
Historic structural movement is a good example.
If a property has previously been underpinned and there is insufficient evidence to establish whether movement is historic and stable or potentially ongoing, the appropriate response is not necessarily for the valuer to guess at a deduction.
Further investigation may be required.
We have encountered matrimonial cases where considerable time has been spent obtaining general building surveys when the outstanding question could only properly be answered by an appropriately qualified structural engineer.
If specialist evidence is reasonably required to resolve an uncertainty that materially affects the valuation, we may need that evidence before providing a reliable opinion.
In some circumstances, a valuation may be possible on an expressly agreed assumption, provided that assumption is appropriate to the purpose of the instruction and its implications are clearly explained. That is different from making an unsupported deduction or ignoring an unresolved defect.
It is also important that relevant information is made available to the valuer whether or not it supports the outcome one party hopes to achieve.
If, for example, a structural engineer has already investigated the matter and produced a report, that is potentially highly relevant evidence. A matrimonial valuation should be based upon the relevant facts, not a selected version of those facts.
Valuing a property under different assumptions
Some of the most interesting matrimonial instructions are those where there is no single answer to the question, "What is the house worth?"
We may instead be instructed to provide valuations on several different bases.
This can happen where substantial works have taken place during the relationship or following separation, where works remain unfinished, or where the court or legal advisers need to understand what the property might have been worth had a particular event not occurred.
Under the RICS Red Book, a special assumption is an assumption that differs from the actual facts existing at the valuation date, or one that would not ordinarily be made by market participants.
For example, we might be asked to value a house on the special assumption that an unfinished extension had been completed, even though we know it was incomplete at the valuation date.
The assumptions need to be clearly defined, appropriate to the valuation's purpose and agreed as part of the instruction. It is not the valuer's job to invent an alternative history for the property.
Two anonymised examples from previous instructions illustrate why this can matter.
An unfinished extension
In one case, the owner was a builder who had started extending his own home before the relationship broke down.
During the divorce, the works stopped.
At the valuation date, the property therefore contained a partially completed extension. Importantly, it wasn't simply a case of valuing the original house plus the value of whatever building work had been completed.
In its unfinished state, the property was actually less attractive than it had been before the project started. A purchaser would need to take on the unfinished scheme and incur the time, cost and uncertainty involved in completing it.
In simple terms, a buyer had to go backwards before they could go forwards.
The instruction therefore required us to consider three scenarios:
As existing: the property with the extension partly constructed.
Assuming the works had never commenced: the property retaining its original arrangement and accommodation.
Assuming the extension had been completed: the property with the proposed works properly finished.
Those were three different valuation questions and potentially three different answers.
Providing the alternative figures enabled the parties and their legal advisers to understand the effect of the unfinished works, rather than simply treating the money spent on the extension as an equivalent increase in the property's value.
A house altered following separation
In another case, one party had moved out of the former matrimonial home and the person remaining at the property subsequently carried out works intended to divide the building informally into two flats.
The alterations included removing walls and changing the internal arrangement.
They also had wider implications. The new layout affected the protected escape route from the second floor because a kitchen had effectively been introduced onto that route without appropriate fire separation between the kitchen and the stairwell/landing.
This was more than a question of whether the new layout was attractive to potential purchasers.
The alterations introduced fire-safety concerns, and a prospective buyer would need to consider the implications of the altered configuration, including the potential need for remedial or reinstatement works. The position regarding any necessary statutory consents would also be relevant.
Consequently, it would have been inappropriate to assume that dividing the property into two units had necessarily increased its value.
We were required to consider the property as it actually existed following the alterations and also on the special assumption that those works had not been undertaken.
The resulting valuation evidence allowed the parties and their advisers to distinguish between the property's actual market position and the hypothetical position had the alterations not occurred.
These examples demonstrate an important principle in matrimonial valuation:
Money spent on a property and value added to a property are not the same thing.
What if one party has made improvements since separation?
This comes up regularly.
One person may have remained in the property after separation and subsequently replaced the kitchen, refurbished the bathrooms, extended the house or undertaken substantial renovations.
They may understandably feel that the money they have spent should be taken into account.
It may well be relevant, but the surveyor needs to be clear about what they are being asked to determine.
Suppose somebody has spent £75,000 improving a property. That does not necessarily mean those works have increased its Market Value by £75,000. They may have added more or considerably less, depending upon the nature of the improvements and how the market responds.
Where properly instructed, we can assess the property under different scenarios — for example, its current value and its value assuming specified improvements had not taken place.
What we cannot determine is how much of the matrimonial asset each person should ultimately receive as a result.
That is a question for the parties and their legal advisers and, where necessary, the court.
Our role is to provide the valuation evidence upon which those decisions can be made.
Can a property be valued at an earlier date?
Yes.
Not every matrimonial valuation relates solely to today's value.
We are sometimes asked to provide a retrospective valuation at a specified historic date. Depending upon the issues in dispute, there may also be a requirement for values at more than one date.
A retrospective valuation does not mean taking today's value and applying a house-price index backwards.
The valuer needs to consider the market as it existed at the relevant valuation date, including appropriate contemporary comparable evidence.
The property's circumstances at that date also matter.
Had an extension already been constructed? What was the accommodation at the time? Had particular alterations happened yet? What was known about a relevant defect?
The further back the valuation date, the more important good records and reliable evidence can become.
What happens after the matrimonial valuation is issued?
Where we are acting under a joint instruction, the report is provided to the relevant parties at the same time.
This avoids one party receiving the valuation in advance of the other and reinforces the independence of the process.
Questions after the report are not unusual.
One party might ask whether a particular comparable was considered. Another might point to a recent sale nearby. Someone may believe an improvement has not been given sufficient weight, while the other party may believe a defect should have resulted in a larger reduction.
The existence of questions does not in itself mean there is anything wrong with the valuation.
Where expert evidence is being used in formal family proceedings, Part 25 of the Family Procedure Rules provides a specific mechanism for written questions.
Under the normal procedure, written questions are for clarification, may be put once, must be proportionate and must generally be raised within ten days of service of the report, with copies sent to the other parties. The rules also allow for different arrangements where the court directs or the relevant parties agree.
Outside formal proceedings, the precise procedure will depend upon the terms of the instruction.
Independence does not mean that a valuer should refuse to reconsider their opinion under any circumstances.
If somebody identifies genuinely relevant evidence that was not previously available, or demonstrates that an important factual assumption was incorrect, a professional valuer should consider it.
But there is an important distinction between providing new evidence and simply being unhappy with the figure.
The question remains the same: does the additional information justify a different valuation?
Frequently asked questions about matrimonial property valuations
Can I instruct a matrimonial valuer without my former partner?
Potentially, yes. However, if both parties will ultimately need to rely upon the valuation, it will often be preferable to agree the appointment jointly before the inspection.
Otherwise there is a risk that you incur the cost of obtaining a valuation only for the other party to reject the appointment and request another valuer.
Where the valuation forms part of formal financial remedy proceedings, different procedural requirements may apply and advice should be obtained from your solicitor.
How much does a matrimonial or divorce property valuation cost?
The fee depends upon the property and the nature of the instruction.
A straightforward valuation of a single residential property will generally be less involved than an instruction requiring several valuation dates, complex special assumptions, multiple properties or additional expert evidence for court proceedings.
Where a Single Joint Expert is required, the scope of the report and any anticipated additional work also need to be considered.
We normally recommend providing the valuer with details of the property, the purpose of the valuation and any proposed letter of instruction so that an appropriate quotation can be prepared.
Further information about our service is available on our Matrimonial, Divorce & Separation Valuations page.
Can we just use estate agents' valuations for divorce?
Sometimes, particularly where both parties are in agreement and simply need an indication of what the property might sell for.
However, an estate agent's market appraisal is not the same as a formal independent valuation prepared by an RICS Registered Valuer.
Where there is disagreement, where the valuation needs to be independently evidenced or where expert evidence is required for court proceedings, a formal valuation will often be more appropriate.
Your solicitor can advise what type of evidence is suitable for your particular circumstances.
Do we both need to attend the inspection?
No.
Both parties can attend, one party can attend or, where suitable access can be arranged, neither party necessarily needs to be present.
Where we require factual information following the inspection, questions can be raised afterwards in a way that maintains the independence and transparency of the process.
Can I speak to the valuer privately?
Administrative matters such as arranging access are one thing. Substantive information that may influence a jointly instructed valuation is different.
Where relevant information is provided by one party, it generally needs to be dealt with transparently so that the valuer does not become the private adviser or advocate of either side.
Does it matter who pays for the valuation?
No. Payment does not determine the valuation outcome.
Where an expert is acting in family proceedings, their duty to assist the court overrides any obligation to the person who instructed or paid them.
The parties can agree between themselves how the fee is divided.
Will defects reduce the matrimonial valuation?
They can, but there is no automatic deduction.
The relevant question is how the defect would affect Market Value. That may depend upon its seriousness, repairability, cost, uncertainty, effect upon mortgageability and how typical buyers would react to it.
The estimated cost of a repair and its effect upon Market Value are not necessarily the same figure.
I've paid for improvements since we separated. Will I get that money back?
That is not a question the valuer can determine.
We can, where properly instructed, assess the property's value under different scenarios — for example, its current value and its value assuming specified improvements had not been made.
How those figures are ultimately treated when the assets are divided is a matter for the parties, their legal advisers and, where applicable, the court.
Can you value the property at an earlier date?
Yes. Retrospective valuations are sometimes required as part of matrimonial and separation matters.
The valuation needs to reflect the property and market circumstances at the specified historic date rather than simply adjusting today's value backwards.
What if we disagree with the valuation?
Questions can be raised in accordance with the agreed instruction or, where the report is being relied upon in formal proceedings, the applicable court procedure.
A valuer should consider relevant evidence and correct genuine errors. They are not, however, required to alter a properly supported valuation simply because one or both parties would prefer a different figure.
Can a matrimonial valuer change their opinion?
Yes, where there is a proper evidential reason to do so.
New comparable evidence, a correction to an important factual assumption or the outcome of a specialist investigation could potentially affect an opinion of value.
Changing an opinion in light of better evidence is not a loss of independence. Changing it simply because one party applies pressure would be.
Do I need a Building Survey as well as a matrimonial valuation?
Not necessarily.
They perform different functions.
A matrimonial valuation considers Market Value. A Building Survey provides a much more detailed assessment of the condition and construction of the property.
Where a particular defect creates uncertainty that cannot be resolved during a valuation inspection, a more specific investigation may sometimes be appropriate — for example, advice from a structural engineer.
Commissioning a Building Survey simply to identify as many defects as possible is not, however, a substitute for determining how the market would actually respond to those defects.
If you require a matrimonial or separation valuation, whether you are a solicitor, mediator or one of the parties involved, we are happy to discuss the proposed instruction before providing a formal quotation. Where we are initially approached by one party, we can also explain how a joint instruction can be arranged.
