What We Do

What Our Probate Lawyers Do - Probate Services

There is no probate matter Keystone’s probate lawyers can’t handle. Our probate services cover a wide range of areas, so whatever your needs, Keystone’s probate attorneys can meet them. Learn more about each of our services by clicking on the links below.

Trust & Will Disputes
Fiduciary Misconduct
Property Disputes
Elder Financial Abuse
Trust & Estate Administration
Conservatorship
Guardianship
Probate Appeals
Trust & Will Disputes
Wills and trusts do not always clearly convey their creators’ true final intentions, nor do they necessarily reflect what their creators’ true final intentions were. If you have concerns about a decedent’s will or trust,  it may be possible to dispute the document. A lawyer can help you determine whether a valid cause exists to bring a dispute.
Fiduciary Misconduct
It’s an unfortunate reality that the fiduciary who has been appointed to represent your interests can drop the ball on their responsibilities, abuse their power or breach their duties. If you believe a fiduciary has committed misconduct, a case can be built and brought against them.
Property Disputes
The attorneys at Keystone regularly litigate disputes over property, so they possess the experience, knowledge and skills to help you achieve your desired outcome in a property dispute matter. Keep reading to learn more about our property dispute services. If you have further questions, call Keystone today to request a free consultation and devise an individualized approach to your case.
Elder Financial Abuse
If you believe yourself or someone you know to be a victim, our elder abuse attorneys can help prevent further abuse and recover any property that was lost as a result of it. Our reliable team can also assist those who believe they have been wrongfully accused of financially exploiting an elder. We have the resources and experience needed to investigate the allegations and build a strong defense on your behalf.
Trust & Estate Administration
Both executors and trustees are fiduciaries, which means that they have a duty to always act in the beneficiaries’ best interests. If they don’t, they could be sued. The best way to avoid such situations is to have skilled estate and trust administration attorneys on your team to guide you and assist with your duties.
Conservatorship
If you are considering guardianship of a parent or someone else in your life, it’s essential to consult with an experienced conservatorship attorney. Our team of lawyers can help you navigate the process and protect your vulnerable loved one’s best interests. Contact us today to request a free consultation.
Guardianship
The attorneys at Keystone Law Group understand the complexities surrounding the establishment of guardianship and are well-equipped to assist adults seeking guardianship over a minor or guardians seeking counseling about their duties.
Probate Appeals
In the probate court, it is unlikely that every party will be satisfied with the outcome of a case. However, while it is rare, if you believe a mistake was made during the court proceedings that led to an imbalanced or incorrect ruling, requesting an appellate court to review the decision may be an option that’s available to you.

Our Record

An Undeniable History of Success

Keystone’s impeccable record speaks for itself. Our unmatched experience and ingenuity enables us to resolve probate matters favorably and efficiently. Keystone’s probate lawyers aim for nothing short of success with every case. For probate services of the highest caliber, turn to Keystone’s probate attorneys.

Fiduciary Misconduct
Property Dispute
Conservatorship
Trust & Estate Administration
Trust & Will Dispute / Elder Financial Abuse
Conservatorship
Trustee Removed
Court Removes Trustee Based on Financial Abuse
Keystone represented a client in her 70s who unknowingly created an irrevocable trust while overly medicated by her son. The son made himself trustee and misappropriated trust assets. At the initial hearing, Keystone’s probate attorneys persuaded the court to immediately suspend the son as trustee and replace him with a private professional fiduciary. Our client’s property was ultimately returned to her as well.
Stolen Funds Recovered
Millions Recovered From Serial Financial Abusers
Keystone first helped its client get appointed as the administrator of her brother’s $50 million estate. Later, Keystone assisted with litigating against the decedent’s two pseudo-caregivers who collectively unduly influenced and defrauded the decedent. In total, Keystone’s probate lawyers were able to help the estate secure the return of more than $2 million in stolen money and property, and obtain a judgment for an additional $1 million.
Emergency Conservatorship
Mother's Life Saved During COVID-19
Keystone helped its client obtain an emergency temporary conservatorship over her mother, who had advanced Alzheimer’s disease and was being kept inside her brother’s home, which was suspected to be a hotbed of COVID-19 cases. As a result, Keystone’s client, over the objection of her brother, was able to remove her mother from the home and into a safe, secure location.
Instructions Provided
Trustee Protected When Distributing Assets
Keystone’s client was the trustee of his sister and brother-in-law’s trust. Because it contained language that was ambiguous in terms of who should receive the primary asset of the trust, the decedent’s home, the client was uncertain how to distribute it. Keystone’s probate lawyers helped the client obtain the clarification he needed to fairly distribute the property according to the trust’s terms and extrinsic evidence.
The "Sugar Daddy" Abuser
Elder Coerced into Giving Assets to Abuser
Keystone’s client sought to invalidate a trust after learning that the decedent from whom they stood to inherit had left the entirety of his estate to a new partner he had just met off a dating site who was 50 years his junior and an ostensible predator. Not long after amending his trust, the abuser died under suspicious circumstances. Ultimately, Keystone was able to reach a favorable settlement for its clients that called for the new version of the trust to be invalidated by arguing that the gift to the partner was an illegal payment for prostitution and the partner’s actions constituted financial elder abuse.
Bullies Never Win
Rightful Share of the Family Business
Keystone’s client had spent most of her adult life managing the family business. When her father’s behavior became turbulent, she believed his unfitness was due to a decline in mental competence or a flagrant disregard of fiduciary duty to act in the best interests of the trust and its beneficiaries. In order to preserve and protect trust assets, as well as her father’s own trust fund distributions, Keystone’s client needed to try to have her father removed as a co-trustee. Keystone’s trust litigation attorneys were able to resolve the case in which its client became the sole company owner after buying out her father’s and sister’s shares.
