In the realm of wills and estates, solicitors’ negligence claims often focus on estate planning and the execution of testamentary instruments and the corresponding standard of care.[1] However, such claims can also arise from estate litigation and even the settlement of estate claims. This danger is aptly demonstrated by Wiener v. Strickland,[2] a recent solicitor’s negligence case in which a client alleged that his former lawyer did not follow his instructions during estate mediation. Inspired by the Court of Appeal’s decision in this case, this article focuses on minimizing the risk of negligence claims arising from assisting clients in the settlement of estates disputes. First, the article reviews the test for solicitor’s negligence applicable to settlements; then it identifies some precautions that lawyers can take when assisting clients with the settlement of estate litigation, to minimize the risk of future negligence claims.

The Test for Solicitor’s Negligence

Historically, lawyers could only be held liable for their conduct during settlement negotiations in clear and exceptional cases of “egregious error” due to public policy considerations, including the desire to “discourage suits and encourage settlement.”[3]

Today, however, there is no justification for holding lawyers to a lower standard when assisting with the settlement of litigation than in other aspects of their role,[4] particularly in light of a lawyer’s obligation to otherwise act with reasonable care, skill and knowledge.[5] Accordingly, proof of an egregious error is no longer required to establish solicitors’ negligence arising from a settlement.[6] Instead, counsel are required to meet the reasonableness standard,[7] meaning that the advice counsel gives must be within the range of reasonable choices, and that counsel must exercise the “effort, knowledge and insight of a reasonably competent lawyer.”[8] The reasonableness or prudence of a settlement and of a lawyer’s advice is to be assessed in light of the circumstances and information that was available when the settlement was reached, “and not with the benefit of hindsight or after acquired information.”[9]

On a related note, an error of judgment will not give rise to actionable negligence as long as the lawyer exercised their judgment with “the effort, knowledge and insight of a reasonably competent lawyer … even if the decision proves to be disastrous.”[10]

Meeting the Reasonableness Standard

There are a plethora of factors that may be considered when assessing the reasonableness of a settlement, depending on the nature of the underlying claim, the specific facts of the case, and the risks inherent to proceeding with the litigation.[11] Even the quality of evidence expected from witnesses and anticipated views as to their credibility may be pertinent.[12] While it would be impossible to address all factors which may be relevant to ensuring that a settlement meets the reasonableness standard here, a few considerations that are relatively universal in nature, which can be applied to a variety of types of litigation, are addressed below. 

Exercise Caution When Recommending Making/Accepting an Early Offer

When providing advice for the purpose of settling an estate claim, counsel ought to be mindful of the stage of the litigation. Accepting a settlement too early during negotiations may be considered negligent, particularly if it is probable that another, better offer may be made later, or if taking further steps in the litigation would strengthen the client’s bargaining position.[13] 

In estate litigation, other factors may also make it unwise for a client to take an early settlement. Consider a will challenge, for example – it can be imprudent for any of the parties to settle before the court determines whether the minimal evidentiary threshold has been satisfied. Looking first to the propounder of the will, settlement negotiations will not be justified unless it would be reasonable to alter the distribution of the testator’s estate and stray from the instructions under the will. If the threshold is met, meaning there is “some evidence which, if accepted, would call into question the validity of the testamentary instrument,”[14] negotiations will be merited, whereas if the threshold is not met and the will challenge is dismissed, there would be no reason to negotiate. On the flip side, it may also be unwise strategically for a will challenger to settle before the threshold has been met, as passing the threshold, if likely based on the evidence they have advanced, can strengthen the challenger’s bargaining position and would also likely yield disclosure from the estate and/or third parties.[15]

Discuss Settlement Without Pressuring the Client

Discussing settlement with a client can be stressful. As noted by Justice Martin, “[o]ffers of settlement often generate stress as they force parties to consider their positions based on imperfect information,” in circumstances where there may be costs consequences should the litigation continue.[16] While counsel has a duty to disclose all information pertinent to settlement to the client and advise them during this stressful time,[17] it is imperative that counsel make it clear that it is ultimately up to the client to choose whether to accept a settlement offer, or alternatively, extend an offer or counter-offer. If this is not clear, a disgruntled client may subsequently bring a claim against the lawyer, alleging that counsel breached their fiduciary duty by pressuring the client to settle, thereby protecting the lawyer’s financial interests over the client’s (assuming that the lawyer also benefitted financially from the settlement).[18] One practical precaution that lawyers can take to undermine such claims is communicating information regarding settlement negotiations with the client in writing, and also summarizing all in-person settlement discussions in writing so they can be put on the file.

Confirm the Client’s Instructions

During settlement negotiations, counsel may only settle a claim in accordance with the client’s instructions, making it essential to fully understand the terms upon which the client is prepared to settle. To prevent ambiguity, it is advisable to ensure that the client’s instructions are recorded in writing, including the amount the client would be willing to accept plus any other essential terms, and are affirmed by the client, preferably with a signature, before settlement negotiations conclude.[19] If the client does end up bringing a negligence claim against counsel, the nature of the instructions given to counsel may be relevant to the outcome.[20] 

Explain the Reach of a “No Claims Over” Clause

It is also advisable to explain to the client that typically a settlement will only bind the parties to the litigation. While it is possible that third parties could also be protected by a “no claims over” clause in a standard form release, the reach of such a clause ultimately ought to be interpreted in light of the objective intentions of the parties to the settlement when the settlement was entered. This point is especially salient if the client’s instructions make it clear that the client will only settle if the ability to commence a related proceeding against a specific third party or parties is preserved. Under such circumstances, counsel ought to take care that none of the terms of the settlement documents could be construed as precluding litigation against that third party, in order to undermine any potential future solicitor’s negligence claim.[21]

Closing

There is no guaranteed way to prevent a solicitor’s negligence claim from arising following the settlement of estate litigation. Thankfully, perfection is not required when assisting clients; rather, the advice given must meet the reasonableness standard. To try to prevent or undermine subsequent negligence claims, counsel may want to keep the strategies discussed above in mind. More specifically:

  • Counsel should refrain from recommending a settlement prematurely; such a recommendation may be negligent.
  • While advising a client regarding settlement, a lawyer should be careful not to pressure the client and should create a record indicating that the client was advised that settlement decisions were theirs alone.
  • The client’s instructions regarding settlement should be affirmed in writing.
  • For most settlements, it will not be necessary to carve out third parties that the client still wants to sue from a “no contest clause” in a standard form release, but counsel should be careful to ensure nothing in the settlement documents would preclude the client from pursuing such claims if that is their intention.
