What to Look for in a Oak Brook Estate Planning Attorney

  • Experience with Illinois law. Estate planning rules vary by state — wills, trusts, and powers of attorney must comply with Illinois-specific statutes. Look for attorneys whose practice focuses on Illinois estate law.
  • Clear, flat-fee pricing. Many estate planning attorneys charge flat fees for standard documents (wills, trusts, POAs). Ask upfront what's included so you can compare costs without surprises.
  • Strong client reviews. Look for consistent 4–5 star reviews that mention responsiveness, clear explanations, and thoroughness — not just friendliness. Estate planning requires attention to detail.
  • Full-service estate planning. The best attorneys handle the full picture — wills, revocable living trusts, healthcare directives, durable powers of attorney, and beneficiary coordination.
