A law firm has claimed that a Court of Appeal judgment in a professional negligence case could have “wide-ranging ramifications” across the lending industry.

The firm also believes the decision also sets a new precedent, in that it changes the legal principle of causation.

Solicitors Rosling King argues that banks, building societies, asset based lenders and surveyors will be affected by the decision that means lenders can recover all of their losses from a negligent valuer arising out of a refinance loan.

The case refines the way in which the Court will apply the long established “but for” test to assess what loss flows from a breach, the law firm said.

Rosling King (RK) acted for the Liquidators of bridging lender, Tiuta International Limited, against De Villiers Surveyors Limited in a case involving the valuation of a property development in Sunningdale, Berkshire.

Tiuta sought to recover from De Villiers the £890,500 loss it suffered arising out of a refinance loan, claiming the valuation report significantly and negligently overvalued the property.

In an earlier hearing in the Chancery Division, the Court ruled that Tiuta’s loss should be limited to the amount lost in ‘topping up’ the original loan (c£272,700).

However, the Court of Appeal has now overturned that decision.

Georgina Squire, head of dispute resolution at Rosling King, said: “This is a resounding win for lenders on an important point of law. Not only does it have wide ramifications for claims against professional advisers, but it also has a much wider impact as it changes the way in which parties have to assess their loss under the “but for” test.

“Lenders will welcome this decision as it settles a contentious issue in relation to how much of their loss they can recover having refinanced. They can now be certain that they may recover their full loss in the event the valuation was negligent, not being restricted to the amount by which the refinance exceeds the original loan.

“The question was should a lender recover all its loss on a refinance loan from a negligent valuer, or is the lender limited to the ‘top up’ advanced after the existing loan is redeemed, because it would have suffered the loss on the existing loan in any event? The Court of Appeal has given much-needed and welcome clarity on the issue.”

De Villiers Surveyors were instructed by Tiuta to value the property in Sunningdale, which was a former nursing home undergoing substantial redevelopment into four three storey mid-terraced houses.

In reliance upon De Villiers’ valuation report, Tiuta advanced funds to its borrower.

The borrower later approached Tiuta to request an increase in the loan facility. De Villiers was instructed to prepare a second valuation report, in reliance upon which Tiuta redeemed the existing loan and advanced further funds to the borrower by way of a refinance. It is the refinance loan that is the subject of the claim.

De Villiers claimed Tiuta could not have suffered a greater loss than the amount by which the indebtedness had increased thereafter, i.e. the loss is limited to the “top up” advance of c.£272,700.

The question before the Court of Appeal was whether there was a pre-existing indebtedness created by the first loan, which prevented the lender pursuing a claim for the full loss suffered by entering into the second loan, on the basis that it has already arisen in the first loan and so could not be claimed on the second loan in accordance with a strict application of the “but for” test.

In its judgment, The Court of Appeal held: “There is nothing unjust in holding the respondent liable in accordance with its own valuation, prepared specifically for the purposes of the second transaction” and that the “second loan is entirely independent from the first loan…had there not been a negligent valuation, the appellant would not have entertained the second transaction and [its] loss is the total advance of the second loan, less the [borrower’s] covenant and the true value of the security.”

The Court of Appeal also stated: “it could be said to be inherently unfair that…. a negligent valuer could use an attack on the legitimate working practices and systems of the appellant as a means of escaping part of the consequences of his or her negligence.”
