Prenuptial & Postnuptial Agreements

Planning for the Future with Clarity and Confidence


Prenuptial and postnuptial agreements are tools for clarity—not conflict. In Illinois, these agreements allow couples to define financial expectations in advance, protect important assets, and reduce uncertainty if circumstances change in the future. Whether you are entering a marriage, navigating a major life transition, or simply looking to align priorities, a well-drafted agreement can provide structure and peace of mind for both parties.

Block | Reid approaches prenups and postnups with the same Families First mindset that guides our broader family law practice: thoughtful strategy, clear communication, and solutions built to last. We help clients address complex financial considerations—including business ownership, real estate, investments, and support provisions. This is achieved while ensuring the agreement is fair, thorough, and enforceable under Illinois law.

  • Asset & Debt Disclosure

    Strong agreements start with clear, complete financial disclosure. We help clients gather and organize the right documents so the agreement is built on accurate information from the beginning.

  • Business & Professional Practices

    Ownership interests, partnership stakes, and professional income can add complexity to any agreement. We identify what needs to be protected and structure terms that reflect value and risk.

  • Real Estate, Investments & Retirement

    Homes, brokerage accounts, and retirement assets often represent years of careful planning. We draft terms that address how these assets will be treated and help reduce uncertainty down the road.

  • Maintenance & Support Provisions

    Spousal maintenance can be one of the most sensitive topics in a prenup or postnup. We help clients negotiate support terms with clarity, fairness, and enforceability in mind under Illinois law.

  • Marital Property Clarity

    Many disputes come down to whether something is considered separate or marital property. We use precise language to define key categories and prevent confusion if the agreement is ever reviewed later.

  • Review, Negotiation & Enforceability

    An agreement is only valuable if it holds up when it matters most. We guide clients through negotiation and drafting with an emphasis on informed consent, proper execution, and long-term reliability.
