Professional(s): [Professional Name(s) and License Type]
Matter/Project: [Description]
Claim Number: [If assigned]


Dear [Recipient Name]:

This firm represents [Client Name] in connection with the professional malpractice committed by [Professional/Firm Name] in [his/her/their] provision of [type of professional services] services. This letter constitutes formal notice of our client's claim and our demand for settlement.


I. NEW HAMPSHIRE-SPECIFIC LEGAL FRAMEWORK

A. Governing Law

Professional malpractice claims in New Hampshire are governed by common law negligence principles. Key precedents include Kelleher v. Marvin Lumber & Cedar Co., 152 N.H. 813 (2005) and Carbone v. Tierney, 151 N.H. 521 (2004).

B. Statute of Limitations

Professional Malpractice: Under N.H. Rev. Stat. Ann. Section 508:4, actions for professional malpractice must be commenced within three (3) years from the date of the act or omission giving rise to the claim.

Discovery Rule: New Hampshire applies the discovery rule. The limitations period begins to run when the plaintiff discovers, or in the exercise of reasonable diligence should have discovered, the injury and its causal relationship to the defendant's act or omission. Kelleher v. Marvin Lumber & Cedar Co., 152 N.H. 813 (2005).

Legal Malpractice: The statute runs from the date the plaintiff discovers or should have discovered the negligence and resulting harm. Carbone v. Tierney, 151 N.H. 521 (2004).

Relevant Dates in This Matter:

  • Date(s) of negligent services: [Date(s)]
  • Date of discovery: [Date]
  • Three-year limitations period expires: [Date]

Construction-related professional services: If the alleged malpractice arises from a deficiency in the design, engineering, planning, surveying, observation, supervision, inspection, or other creation of an improvement to real property, RSA 508:4-b may also impose an eight-year outer limit measured from substantial completion. The section defines substantial completion, addresses phased projects and longer written warranties or guarantees, contains special rules for fraudulent misrepresentation or concealment, and preserves specified possession/control and repair/maintenance liabilities. Apply the section's full text rather than treating it as an exception-free deadline for every professional-malpractice claim.

C. Comparative Negligence

New Hampshire follows a modified comparative negligence system under N.H. Rev. Stat. Ann. Section 507:7-d. A plaintiff may recover damages only if their negligence is not greater than the defendant's negligence. If the plaintiff is 50% or more at fault, recovery is completely barred. If less than 50%, damages are reduced proportionally.

D. Standard of Care Under New Hampshire Law

Under New Hampshire law, a professional must exercise the degree of care, skill, and knowledge which is ordinarily exercised by reasonably careful members of that profession. Kelleher v. Marvin Lumber & Cedar Co., 152 N.H. 813 (2005).

Key Case Law:

  • Attorneys: Must possess and exercise such care, skill, and knowledge as is ordinarily exercised by a reasonably careful attorney practicing in the same field. Carbone v. Tierney, 151 N.H. 521 (2004).
  • Accountants: Must perform services in accordance with GAAP and GAAS standards and exercise reasonable professional care. Spherex, Inc. v. Alexander Grant & Co., 122 N.H. 898 (1982).
  • Engineers/Architects: Must exercise the skill and care customarily used by practitioners in the profession. MacCleod v. Ball, 140 N.H. 159 (1995).

E. Expert Witness Requirements

Expert testimony is generally required in professional malpractice cases to establish:

  1. The applicable standard of care;
  2. That the defendant breached that standard; and
  3. That the breach proximately caused the plaintiff's damages.

Carbone v. Tierney, 151 N.H. 521 (2004).

Exception: Expert testimony is not required when the professional's negligence is so obvious that laypersons can recognize it without specialized knowledge.

Certification: We have retained a qualified expert who has reviewed the relevant documents and has concluded that the applicable standard of care was breached and that such breach proximately caused our client's damages.

F. Damage Caps

New Hampshire does not impose statutory caps on damages in professional malpractice cases.

G. Privity and Third-Party Claims

Legal Malpractice: Generally requires an attorney-client relationship. New Hampshire recognizes limited exceptions for intended third-party beneficiaries in estate planning cases. Sisson v. Jankowski, 148 N.H. 503 (2002).

Accountant Malpractice: Third parties may recover where the accountant knew the work would be relied upon by identifiable third parties. Spherex, Inc. v. Alexander Grant & Co., 122 N.H. 898 (1982).

H. Breach of Fiduciary Duty

New Hampshire recognizes breach of fiduciary duty as a separate cause of action. Professionals who occupy positions of trust owe fiduciary duties to their clients. Baxter v. Fairfield Fin. Mortg. Grp., Inc., 794 A.2d 152 (N.H. 2002).

Demand Letters

A demand letter is a formal written request to fix a problem or pay what is owed, sent before anyone files a lawsuit. It gives the other side a real chance to settle, creates a record of your attempt to resolve things, and in many cases (unpaid debts, insurance claims, broken contracts) starts a legally required response window. A well-written demand letter lays out what happened, what you want, and a deadline to act, which is often enough to get results without ever going to court.
