Estate, Trust, and Probate Litigation for Families With Significant Assets
Estate litigation is rarely just about money. It often involves grief, family history, long-standing expectations, private financial information, and doubts about whether someone honored the wishes of a parent, spouse, business owner, or loved one.
When substantial assets are involved, the stakes are even higher. A dispute may involve real estate, closely held businesses, trust assets, investment accounts, fiduciary decisions, tax issues, or concerns about undue influence near the end of someone’s life.

Probate Litigation
Probate litigation can arise when heirs, beneficiaries, creditors, or family members disagree about how an estate is being handled. In some cases, the issue is whether a will is valid. In others, the concern is whether the personal representative is properly managing estate assets.
Probate disputes may involve:
- Challenges to the validity of a will
- Claims of undue influence
- Questions about mental capacity
- Allegations of fraud or forgery
- Disputes over estate accountings
- Claims against a personal representative
- Disagreements over distributions
- Conflicts involving real estate or business interests
- Financial abuse of an elderly or vulnerable person
In high-value estates, even a small decision can have significant financial consequences. A delayed sale, poor asset management, missing records, improper distributions, or tax-related mistakes may affect what beneficiaries ultimately receive.
Will Contests and Undue Influence Claims
A will contest often begins with a concern that something changed at the wrong time, for the wrong reason, or under the wrong pressure.
A family member may question why a longtime estate plan was suddenly revised. A beneficiary may believe a caregiver, relative, friend, or advisor influenced a vulnerable person. A disinherited spouse or child may want to understand whether they have legal rights.
Will contests may involve allegations of:
- Undue influence
- Lack of testamentary capacity
- Fraud
- Forgery
- Improper execution
- Mistake
- Revocation
- Suspicious late-life changes to an estate plan
These cases depend on highly specific details such as medical records, witness testimony, attorney notes, financial transactions, communications, and the decedent’s relationships. Our firm investigates the circumstances surrounding the will and develops a litigation strategy based on the evidence.
Trust Litigation
A trust can provide privacy, structure, and long-term asset management. But when a trustee fails to communicate, refuses to provide information, mismanages assets, favors one beneficiary over another, or uses trust property improperly, litigation may become necessary.
Trust disputes may involve:
- Breach of fiduciary duty
- Trustee misconduct
- Misappropriation of trust funds
- Failure to account
- Failure to make proper distributions
- Conflicts of interest
- Self-dealing
- Improper investment decisions
- Disputes over trust interpretation
- Challenges to trust validity
- Removal of a trustee
Trustees have legal duties. Beneficiaries also have rights. There is a risk of conflict when either side misunderstands those duties and rights.
Fiduciary Misconduct
Many estate and trust disputes center on fiduciary conduct. A trustee, personal representative, or guardian is trusted with authority over someone else’s property, care, or financial interests. That authority comes with legal obligations.
Concerns about fiduciary misconduct may include:
- Missing or incomplete accountings
- Unexplained transfers
- Commingling of funds
- Excessive compensation
- Failure to preserve assets
- Favoring one beneficiary over another
- Poor investment or management decisions
- Lack of communication
- Refusal to provide documents
- Conflicts of interest
Not every disagreement means misconduct occurred. But when the paper trail raises questions, a professional legal review can help determine whether litigation is appropriate. Just discussing the situation with an attorney doesn’t set litigation in motion. If you have any questions, it’s best to ask before the situation grows worse.
Guardianship Litigation
Guardianship disputes are deeply personal. They may involve an aging parent, an adult child with disabilities, a vulnerable family member, or someone who wants to maintain independence despite allegations of incapacity.
Families may disagree about:
- Whether guardianship is necessary
- Who should serve as guardian
- Where the person should live
- What medical care should be provided
- How assets should be managed
- Whether a guardian is acting appropriately
- Whether less restrictive alternatives are available
Contesting a Guardianship
Not every elderly person or vulnerable adult needs a guardian. In some cases, a guardianship petition may be unnecessary, overly broad, or based on incomplete information.
Our firm can assist with matters involving:
- Challenges to incapacity allegations
- Opposition to appointment of a guardian
- Disputes over who should serve as guardian
- Protection against mistreatment or financial exploitation
- Requests for less restrictive alternatives
- Removal or replacement of a guardian
The court’s focus is the best interest and protection of the person at the center of the case. Our firm works to present the facts clearly and protect the client’s rights throughout the process.
A Litigation Strategy Built Around Your Goals
Estate litigation can become expensive, emotional, and disruptive. Not every dispute should be pushed into a prolonged courtroom fight. At the same time, some matters can’t be resolved without firm legal action.
Our firm helps clients evaluate:
- What the documents say
- What the financial records show
- Whether fiduciary duties may have been breached
- Whether the claim has evidentiary support
- Whether negotiation, mediation, or litigation makes sense
- What risks and costs may be involved
- What outcome the client is actually trying to achieve
A strong litigation strategy should be clear-eyed. It should account for the legal issues, the family dynamics, the financial stakes, and the practical realities of the dispute.

Frequently Asked Questions About Florida Estate Litigation
Estate litigation refers to legal disputes involving a deceased person’s estate, will, trust, beneficiaries, heirs, fiduciaries, or property. These disputes may arise during probate, trust administration, guardianship proceedings, or after concerns develop about how assets were transferred or managed.
A will may be contested for reasons such as undue influence, lack of capacity, fraud, forgery, improper execution, or suspicious changes made near the end of someone’s life. The strength of a will contest often depends on medical records, witness testimony, estate planning history, and the circumstances surrounding the signing of the document.
In some cases, yes. A trustee may be removed if there is evidence of misconduct, breach of fiduciary duty, conflict of interest, failure to account, mismanagement, or other conduct that harms the trust or beneficiaries. The court will consider the facts and whether removal is appropriate under the circumstances.
It is worth documenting the concerns as clearly as possible. Bank records, changes to estate planning documents, unusual transfers, new relationships, isolation from family, or sudden changes in behavior may all matter. An attorney can help evaluate whether guardianship, probate litigation, trust litigation, or another legal remedy may be appropriate.
No. Many probate disputes are resolved through negotiation, mediation, or settlement. However, trial may be necessary when the parties cannot agree, when fiduciary misconduct is serious, or when the validity of a will, trust, or major transaction must be decided by the court.
The answer depends on the type of case. Heirs, beneficiaries, trustees, personal representatives, creditors, guardians, and other interested parties may have standing in certain disputes. Whether someone has the right to bring a claim depends on their relationship to the estate or trust and the issue being challenged.
