A prenuptial agreements attorney couples in St. Charles trust.

A prenuptial agreement is not a prediction of divorce — it is a plan two adults make together about how their financial life will work if the marriage does not. Christine Marshall drafts and negotiates Illinois prenups and postnups that read plainly, hold up in court, and do not poison the engagement.

Overview

The Law Office of Christine Marshall drafts, negotiates, and reviews Illinois prenuptial and postnuptial agreements under the Uniform Premarital Agreement Act. Every agreement is built around the specific facts of the couple — premarital assets, family businesses, professional practices, inheritances, blended-family estate plans, and each party's expectations for the marriage.

A prenup that fails at divorce is worse than no prenup at all. Illinois courts scrutinize enforceability closely: voluntariness, disclosure, independent counsel, and timing all matter. Christine's drafts are built to survive that scrutiny two or twenty years later.

Christine represents one party in the negotiation and insists the other party have independent counsel. That is not an inconvenience — it is the single strongest predictor of enforceability.

Situations We Handle

The problems clients bring us — and what we do about them.

01

A family business that pre-exists the marriage

Without a prenup, appreciation of a premarital business during the marriage can become marital property. A well-drafted agreement locks in the business's non-marital status and defines how future growth is treated.

02

A second marriage with children from prior relationships

Blended families need clear rules for how each spouse's estate flows to their respective children — while still providing for the surviving spouse. Prenups and coordinated estate planning are the tools.

03

Significant disparity in premarital wealth

One spouse enters with real assets; the other does not. A fair, disclosed prenup can protect the premarital estate while providing meaningful support terms if the marriage ends.

04

A future inheritance that has not yet been received

Illinois treats inherited property as non-marital, but comingling can compromise that. A prenup makes the intent explicit and reduces the risk of an ambiguous record.

05

Anticipated career changes or graduate school

Couples supporting one spouse through medical school, law school, or professional training often want clarity on how that investment is recognized at divorce. Prenups can address it.

06

A postnup after the marriage has already begun

Sometimes the conversation happens after the wedding — after a business is sold, an inheritance received, or a career pivot made. Illinois postnups are enforceable when drafted with the same care.

How Christine Works

A composed, protective process.

Four decades of family law practice, distilled into a process built for the pace of real families in Kane County.

  1. 01

    A candid conversation about what the agreement should do

    Christine's first meeting focuses on the couple's actual goals — not a template. What does each party want protected, and what does each want provided?

  2. 02

    Full and fair disclosure

    Each party discloses assets, liabilities, and income in writing. Complete disclosure is one of the strongest defenses against a future enforceability challenge.

  3. 03

    A draft that reads plainly

    The document is written to be understood — not to intimidate the fiancé into signing. Christine has seen too many agreements fail because one party did not understand what they signed.

  4. 04

    Independent review, then signature well before the wedding

    The other party's counsel reviews and negotiates. Both parties sign with enough time before the wedding that a challenge based on duress will not succeed.

Frequently Asked

Answers to the questions we hear most.

Yes. Illinois adopted the Uniform Premarital Agreement Act. A prenup is enforceable if it is in writing, signed voluntarily by both parties, and made with fair and reasonable disclosure of assets and liabilities (or a valid written waiver of disclosure). Courts do not enforce prenups that are unconscionable when signed.

Property division at divorce or death, treatment of premarital and inherited assets, protection of business interests, maintenance (spousal support) waivers or terms, treatment of retirement accounts, and any other matter not against Illinois public policy. Prenups cannot restrict child support or dictate custody.

As far in advance of the wedding as possible — 30 to 90 days minimum is prudent. Agreements signed the week of the wedding are vulnerable to challenges based on duress or lack of voluntariness. Christine will not draft a rushed prenup that will not hold up.

Both parties should have independent counsel. Christine represents one party; the other should have a lawyer of their own choosing to review the draft. Independent representation is one of the strongest defenses against a later challenge to enforceability.

The same contract, signed after the wedding rather than before. Illinois allows them; they are analyzed under general contract law rather than the Uniform Premarital Agreement Act, and require careful drafting to remain enforceable.

Sometimes. Prenups also govern how future assets — an inheritance you have not yet received, a business you may later build, retirement contributions from your career — are treated at divorce. If either party has a strong reason to plan for future acquisitions, a prenup is worth discussing.

Yes — and this is one of the most common reasons Christine drafts them. A well-drafted prenup keeps a business interest as non-marital property and protects future appreciation from a marital-property claim at divorce.

Straightforward Illinois prenups are often quoted at a flat fee after the free consultation. More complex agreements involving business valuations, trusts, or blended-family estate planning are billed hourly. Call (815) 666-4873 for a candid estimate.
