Probate Litigation: What It Is, What It Costs, and How It Works

What Triggers Probate Litigation

Probate litigation begins when someone with legal standing files a formal challenge in probate court. The most common triggers include disputes over a will's validity, allegations of executor misconduct, disagreements about how assets should be distributed, and claims that a dependent was inadequately provided for.

Unlike the standard administrative probate process — where the court simply supervises an orderly distribution — litigation turns probate into an adversarial proceeding with opposing parties, discovery, and potentially a trial.

Types of Probate Disputes

Will contests challenge the document itself, arguing the testator lacked mental capacity, was subjected to undue influence, or that the will was forged or improperly executed.

Executor removal actions seek to replace a personal representative who has breached their fiduciary duty — self-dealing, failing to account for estate assets, or refusing to communicate with beneficiaries.

Construction disputes arise when the will's language is ambiguous. Both sides ask the court to interpret what the testator meant by a particular provision.

Family provision claims (common in the UK, Australia, Canada, and New Zealand) allow eligible dependents to argue the will failed to make adequate provision for their maintenance and support, regardless of what the document says.

The Litigation Timeline

Most probate litigation follows a predictable arc, though the exact duration varies by jurisdiction and complexity.

Early stages: Filing the petition, notifying parties, and requesting a temporary restraining order if assets are at risk of being dissipated.

Discovery: Both sides exchange documents, take depositions, and retain expert witnesses. Medical records, financial statements, and witness testimony get assembled into the evidentiary record.

Mediation: Mediation is common before trial. The research estimates that more than 80% of properly prepared claims settle before trial, saving both sides the cost and emotional toll of a hearing.

Trial: If mediation fails, trials can take 12 to 36 months to resolve. Probate trials can stretch longer than civil litigation because they often involve complex family dynamics, multiple parties, and expert testimony on capacity and influence.

What It Costs

Under the American Rule (used in the US), each side pays their own attorneys. Initial retainers for probate litigation typically range from $5,000 to $10,000, with hourly rates of $300 to $700 depending on the market.

In "loser pays" jurisdictions (UK, Canada, Australia), the losing party may be ordered to pay a portion of the winning side's legal fees. Courts make exceptions when the litigation was caused by the testator's own ambiguous drafting or when the challenger had reasonable grounds to investigate.

Total costs for a fully litigated will contest commonly land between $20,000 and $100,000 per side. Simple executor removal actions cost less; complex multi-party disputes with extensive expert testimony cost more.

When Litigation Makes Sense

Not every estate dispute belongs in court. Litigation makes strategic sense when the amount at stake significantly exceeds the expected legal costs, when you have strong documentary evidence supporting your claim, and when settlement negotiations have genuinely stalled.

It rarely makes sense when the dispute is primarily emotional rather than financial, when the estate is small enough that legal fees would consume most of its value, or when family relationships matter more than the dollar amount in question.

Alternatives to Court

Mediation costs a fraction of litigation and resolves many estate disputes. Arbitration's availability and effect depend on local law and any agreement among the parties. Family settlement agreements let all interested parties negotiate a distribution that differs from the will, provided everyone with standing agrees.
