Estate Planning

Estate Planning is the process by which an individual or family takes an active part in determining what will (or will not) happen to their person and property during their lifetime and following their death. It is impossible to remove the uncertainty from life, but with thoughtful planning, one can take comfort in shaping the terms of their legacy.

Probate is the legal process by which a person’s estate is settled, which generally involves the disposition of assets and the satisfaction of creditors. Aside from those estates that qualify for Summary Administration, a Personal Representative (aka Executor) is required to be represented by a licensed
Florida attorney to administer a decedent’s estate.
