As an associate in Hahn Loeser’s Trusts & Estates Group, Charles A. Williams focuses on taxation matters and counsels clients through the various aspects of trust and estate planning. Charles regularly performs tax planning, consulting, and compliance for clients with multiple business entities, including foreign and domestic trusts, corporations, partnerships, and disregarded entities. His background includes experience with tax controversies, litigation, and fiduciary compliance. This background provides maximum benefits for clients looking to combine current income tax benefits, including analysis of international and domestic tax credits and treaties, with future trust and estate tax planning.

Prior to building his tax practice, Charles served as a Judge Advocate General (JAG) in the United States Marine Corps at Marine Corps Air Station (MCAS), in Yuma, Arizona as a criminal defense attorney. In that role, he defended Marines in criminal cases and separation proceedings with positive results, including multiple cases that resulted in full acquittals, dismissals, withdrawals of charges, and negotiated sentences through motions, interviewing techniques, and expert witness preparation, including forensic accounting. He then briefly transitioned to providing legal services in the areas of wills, trusts, family law, and taxation for Marines and their families.
