Koenig Law Firm is an esteemed estate planning, probate litigation, real estate, and commercial law practice in Rock Island, Illinois. Established in 1975 by Philip E. Koenig-consistently honored as an Illinois Leading Lawyer every year since 2003-the firm provides sophisticated counsel in wills, trusts, elder law, business transactions, and bankruptcy across the Quad Cities and Western Illinois.

Distinguished Estate Planning and Real Estate Advocacy in Rock Island

Preserving family wealth, executing real estate transactions, and managing disputed probate matters require counsel combining transactional finesse with trial mastery. Koenig Law Firm stands as one of the most respected practices in Rock Island County, serving the Quad Cities since 1975. Led by founding attorney Philip E. Koenig, a graduate of Southwestern University School of Law and past chair of the ISBA Real Estate Law Section Council, the practice is unique among estate firms. While many trust attorneys avoid courtrooms, attorney Koenig is a veteran litigator who aggressively defends client interests in contested wills, fiduciary disputes, and commercial conflicts. When property owners and business leaders need to find a lawyer who delivers courtroom-tested representation, Koenig Law Firm provides exceptional legal leadership.

Comprehensive Legal Practice Areas

Attorney Koenig brings over four decades of focused mastery across estate, commercial, and property disciplines throughout Western Illinois and Eastern Iowa:

  • Wills, estate planning and probate lawyers: Structuring living trusts, irrevocable trusts, wills, and powers of attorney to avoid probate.
  • Probate lawyers: Representing fiduciaries and beneficiaries in probate court, contested will litigation, and estate tax settlement.
  • Residential real estate lawyers: Facilitating residential home sales, title examinations, boundary disputes, and closing procedures.
  • Commercial real estate lawyers: Handling commercial acquisitions, leasing agreements, mechanics lien claims, and construction litigation.
  • Business and real estate lawyers: Advising closely held companies and farms on succession planning and asset protection.
  • Contract lawyers: Structuring partnership agreements, vendor contracts, corporate bylaws, and commercial transaction documents.
  • Bankruptcy lawyers: Guiding debtors and creditors through Chapter 7, 11, and 13 bankruptcy proceedings and foreclosure defense.
  • Business litigation lawyers: Litigating commercial disputes, creditor rights collections, and civil appeals across Illinois courts.

The Litigator and Transactional Advantage

What distinguishes Philip E. Koenig is his versatility as both a transactional attorney and a trial-tested litigator. When trust and estate controversies erupt-such as allegations of undue influence, executor misconduct, or ambiguous language-clients benefit from an advocate who understands probate evidence and courtroom procedure. Peer-recommended as an Illinois Leading Lawyer every year since 2003, attorney Koenig ranks in the top five percent of Illinois attorneys. If you need a lawyer immediately to protect an estate from mismanagement or resolve an urgent commercial dispute, Koenig Law Firm delivers decisive advocacy.
