Questions, answered.

What are the benefits of divorce mediation over litigation?

In mediation, you stay in control of the outcome rather than leaving decisions to a judge. The process is private, you choose when and where to meet, and it typically costs less and moves faster than trial. Mediation also reduces stress and conflict, which is especially important for children.

Why do I need a health care power of attorney?

A health care power of attorney lets you designate a trusted person to make medical decisions if you become incapacitated. Without one, your family may have to go to court through a lengthy and expensive guardianship process. Planning ahead gives you control and peace of mind.

What is the difference between a health care power of attorney and a living will?

A health care power of attorney designates someone to make medical decisions on your behalf. A living will sets forth your own wishes about medical treatment and end-of-life care. Together, they form a comprehensive plan for your healthcare decisions.

What does probate involve?

Probate is the court process for distributing an individual's assets after death. It also handles other legal matters, including disputes over wills, trusts, and fiduciary duties. Our firm guides families through probate administration, will contests, and trust settlement.

Do I need an attorney for estate planning?

Estate planning can become overwhelming quickly. An attorney ensures your documents are properly drafted, legally sound, and aligned with your wishes. We help you create effective and understandable plans so your family knows what to expect.

What legal needs come with aging?

As you age, your estate plan may need updating to reflect life changes. You may also need guidance on incapacity planning, special-needs trusts, conservatorships, or guardianships. Our elder law practice helps you prepare for these transitions.
