When an executor, trustee, or other fiduciary starts making decisions that feel self-serving, careless, or strangely delayed, families often sense that something is wrong long before they can prove it. The hard part is usually not spotting the red flags. The hard part is documenting them clearly enough that a lawyer, mediator, insurer, or court can understand what happened.
That is especially true in estate and trust disputes. Fiduciaries are generally expected to act in good faith, follow the governing document, protect assets, keep records, and place the interests of the estate or trust ahead of their own. Courts and legal commentators commonly describe these duties in terms of loyalty, care, prudence, impartiality, recordkeeping, and protecting trust property. Cornell Legal Information Institute and the American Bar Association both outline these core fiduciary duties, and New York’s court system explains that fiduciaries may not put their personal interests ahead of the estate’s interests.

In this post you’ll learn how people often document three common categories of fiduciary misconduct: conflict of interest, asset misuse, and failure to act. You’ll also see what evidence tends to matter, how to organize it, and where many claimants lose leverage by keeping only a general list of complaints instead of a provable timeline.
If you want more background on the legal framework behind these disputes, it may help to start with our overview of core fiduciary duties and surcharge claims.

A lot of fiduciary disputes begin with statements like:
Those concerns may be legitimate. But in probate and trust litigation, general suspicion often carries less weight than specific, organized proof. Courts commonly look for concrete acts, omitted acts, dates, transactions, account entries, communications, and resulting loss. For example, New York Surrogate’s Court decisions have emphasized that broad accusations of “general negligence” or objections that fail to identify specific conduct may be dismissed as too vague.

That’s why documentation tends to do two things at once:
In many disputes, the issue is not one dramatic event. It is a pattern: missing records, undisclosed transactions, unexplained reimbursements, delayed distributions, ignored tax obligations, lapsed insurance, below-market sales, or silence in response to reasonable requests. The ABA’s guidance for executors and trustees also emphasizes careful records, receipts, communication, formal handling of expenses, and full documentation of decisions. American Bar Association
Before documenting wrongdoing, it helps to identify who owed what duty to whom.
