Lawyer Profile

Philip J. Koenig
Attorney Philip E. Koenig has more than 30 years of experience in trusts, wills, estate planning, tax, real estate, and general business issues. Koenig is the rare combination of an experienced litigator and a transactional lawyer. He provides complete estate planning services including tax planning, preparation of trust agreements, wills and powers of attorney, and estate administration. He has extensive experience with contested estate matters. He also handles mechanic’s lien and construction litigation.

Koenig often utilizes living trusts as a preferred method to avoid probate and streamline the process of estate administration following a death. His trial experience includes real estate, estate, probate and tax litigation. His clients have achieved positive results in the trial and appellate courts.

He has extensive experience dealing with tax audits and tax dispute issues for personal and small or closely-held businesses. As a result of his vast trial and transactional experience, he is often called upon with business formation, entity and incorporation issues. While he enjoys helping clients work out their complex legal problems, he receives just as much satisfaction from his efforts to avoid legal problems through proper planning and structuring of entities or assets.

The Koenig Law Firm is part of the Hyatt Group Legal Plans Attorney Network.
