What is professional malpractice in Delaware?

It's when a licensed professional — an attorney, accountant, financial advisor, or architect — fails to meet the accepted standard of their field and causes you financial harm. Unlike medical malpractice, these cases usually involve economic rather than physical losses.

What makes a strong professional malpractice case in Delaware?

A clear, demonstrable error (a missed deadline, bad advice, or mishandled funds), an expert who will testify the standard of care was breached, and documented financial losses traceable to the error. Engagement letters and billing records are critical.

Q: How is a professional malpractice settlement calculated in Delaware?

Damages equal the financial loss the error actually caused. For attorney malpractice, Delaware typically requires proving the "case within a case" — that you would have won the underlying matter but for the error. Expert testimony from the same profession is almost always required.

Q: How long do I have to file a professional malpractice claim in Delaware?

Delaware generally allows about 2 years, often running from when you discovered (or should have discovered) the error. For attorney malpractice, the "continuous representation" rule can pause the clock while the lawyer keeps handling the matter.

A Delaware professional malpractice case holds a licensed professional accountable for falling below the standard of their profession and causing financial loss. Attorney, accounting, and financial-advisor malpractice are the most common, and expert testimony from someone in the same field is almost always required to establish the breach.
