Getting married in Illinois—especially around Chicago—comes with big financial questions. A clear, well‑timed prenup lets you decide how property, debts, and support are handled so you’re not relying on default rules. Here’s a practical checklist and what real costs look like.
Quick checklist (save this)
- Start early: 4–8 weeks before the wedding is ideal.
- Exchange disclosures: assets, debts, income (attach summaries).
- Discuss goals: separate vs. marital property, business interests, real estate, and support parameters.
- Draft → review → revise: avoid last‑minute pressure.
- Sign before a notary; keep originals with your estate plan.
What drives the cost of a prenup in Illinois?
Two things matter most: complexity (businesses, real estate, equity comp) and number of revisions. Flat‑fee packages are common for simple agreements; hourly billing appears when there’s negotiation.
- Simple (few assets, aligned goals): $750–$2,000 per party.
- Moderate (property + investments): $2,000–$5,000 per party.
- Complex (businesses/equity/real estate): $5,000+ per party.
How to keep costs predictable
- Agree on the big picture first—division rules, support parameters, and what stays separate.
- Bring organized disclosures (PDF statements, a net‑worth snapshot).
- Limit back‑and‑forth: batch comments and focus on the provisions that really matter.
What you can (and can’t) put in a prenup
Great prenups cover classification of separate vs. marital property, management of assets and debts, and spousal support terms within public‑policy limits. Child support and custody aren’t set by prenup.
