Probate litigation is what happens when an estate matter stops being routine and turns into a legal dispute. That dispute might involve a will, a personal representative, a creditor claim, a family home, or even a question about who the rightful heirs are. In general terms, probate court is often designed to supervise the transfer of property after death, but when conflict enters the picture, the process can become slower, more expensive, and far more personal.
If you’re trying to understand the basics, this is a good place to start. In this post you’ll learn what probate litigation is, what kinds of fights end up in court, why some estates become contested, what the process often looks like, and when families begin looking for an attorney with demonstrable experience in highly similar matters.

Probate is the legal process used to administer a deceased person’s estate. Depending on the state and the type of property involved, probate may include validating a will, appointing a personal representative or administrator, identifying heirs and beneficiaries, notifying creditors, paying debts and taxes, and distributing remaining assets. The Legal Information Institute at Cornell and the Uniform Probate Code materials collected by Cornell Law School both reflect how probate law often centers on court supervision of estate administration, while also varying significantly from state to state.
Probate litigation begins when someone asks the court to resolve a contested issue instead of simply processing the estate administratively. That can happen before a will is admitted to probate, during administration, or near the final distribution of assets.
This distinction matters because most estates never become full-blown court fights. A recent Maryland judiciary-related study found that in fiscal year 2025, only 0.60% of all estate matters involved a “genuine dispute” requiring adjudicative action, even though many more estates still required some court involvement for administrative reasons (Maryland Department of Legislative Services PDF). That’s a useful reminder: probate litigation is not the norm, but when it happens, it can become the defining issue in the estate.
Estate disputes are rarely just about documents.
They often involve grief, old family resentments, second marriages, caregiver relationships, blended families, changing promises, and property with both financial and sentimental value. The American Bar Association recently described probate litigation as a collision of “people, money” and family narratives, with the family home frequently becoming a flashpoint because it combines emotional attachment with major economic value.
That tracks with what many families experience in real life. One sibling may want to sell a house immediately. Another may want to keep it. A third may already be living there and believe years of caregiving or maintenance created a special claim. Those disagreements can quickly shift from “family conflict” into claims involving possession, title, fiduciary duty, reimbursement, partition, or inheritance rights.
In other words, probate litigation often grows out of ordinary family tension meeting formal legal procedure.
For beginners, it helps to think of probate litigation in categories.
A will contest challenges whether a will is valid. According to the Santa Clara County Superior Court self-help materials, common grounds for challenging a will include:
