Trust & Estate Litigation

and Planning
Trusts and estate litigation pertains to the legal disputes and conflicts that arise in relation to trusts, wills, and the distribution of assets in an estate. It involves resolving conflicts such as challenges to the validity of a will, claims of undue influence or fraud, disputes over the interpretation of trust documents, and disagreements among beneficiaries regarding their rights and entitlements.

Employment and Labor Law

Litigation and Advising
Human resources and workplace disputes are challenging. On the one hand, these issues often involve a number of complex, overlapping, and ever-changing state and federal laws. And, of course, on the other hand, these issues can be and usually are emotionally charged. Our priority is to ensure the comfort and confidence of our clients during these challenging moments.

Business Litigation

and Advising
Business litigation refers to legal disputes and conflicts that arise in the context of business transactions and operations. It encompasses a wide range of issues such as breach of contract claims, partnership or shareholder disputes, intellectual property matters, breach of fiduciary duty claims, and other business disputes that require resolution through litigation or other dispute resolution methods, such as arbitration or mediation.

Insurance Coverage

Bad Faith
and Conduct
Insurance coverage bad faith and conduct refers to situations where an insurance company acts in an unfair, deceptive, or unreasonable manner when handling an insurance claim. This can include denying a valid claim without proper investigation, delaying the claim settlement unreasonably, or failing to provide a reasonable explanation for claim denials, potentially leading to legal action by the policyholder.

Guardianship Protection

and Vulnerable Protection
Guardianship protection refers to the legal process of appointing a guardian to protect and make decisions on behalf of an individual who is deemed incapable of managing their own affairs due to age, illness, or disability. Conservatorship, on the other hand, involves the appointment of a conservator to manage the financial and legal matters of an individual who is unable to handle their own financial affairs due to incapacity or vulnerability.

Success Stories

Shannon is Smart, Committed, Dedicated to her craft, and Responsive – Hard to get a better combination than that.


I have had the opportunity to work closely with Ms. Falon, as a corporate representative,  on a multi-year bad faith case involving a large regional insurance carrier. Ms. Falon is very detail oriented, but yet understands the big picture of our lawsuit. Ms. Falon has a very pleasant personality and has been a pleasure to work with.


In my parents’ final years, I found myself dealing with a sibling who had stopped talking to me and was exerting influence over our parents. I needed help protecting my aging parents, my visitation with my parents, the management of their estates, and the administration of their estate plan. With the assistance of the lawyers at Denevan Falon Joyce, I was able to continue my relationship with my parents, provide input into their care, obtain information about their estates, protect their estate planning, and make sure their estate was distributed according to their wishes.


I just can’t say enough good things about this firm. Corey, Shannon and Meghann were exceptional! Our case was more than just a case to them. They were so dedicated and actually cared so much about what happened to us! Their dedication was outstanding! They were there when we needed them and we were treated with respect and so much kindness ! I highly recommend them and would definitely give them 5 stars ! I will always be thankful that they were recommended to us and took our case .
