Integrating Marital Agreements Into Your Broader Legacy Strategy
Marriage isn’t just an emotional commitment—it’s also a legal and financial partnership that can dramatically affect your estate planning outcomes. Whether you’re preparing for marriage or already years into one, pre-nuptial and post-nuptial agreements can be essential tools in protecting your assets and clarifying intentions for your legacy.
At Peabody Law, we’ve helped clients throughout Southlake, Colleyville, Trophy Club, Westlake, Keller, and Grapevine thoughtfully integrate marital agreements into comprehensive estate plans. In this guide, we explore how these agreements—often viewed as sensitive or even taboo—can actually enhance clarity, fairness, and long-term asset protection.
Understanding Pre-Nuptial and Post-Nuptial Agreements
A pre-nuptial agreement (“prenup”) is a legally binding contract executed before a marriage begins, while a post-nuptial agreement (“postnup”) is entered into during the marriage. Both outline how assets, debts, and spousal support will be handled in the event of divorce or death.
While these agreements are often associated with divorce protection, they can also play a critical role in estate planning, especially for:
- Blended families
- High-net-worth individuals
- Business owners
- Individuals with significant separate property or inheritance
Why Marital Agreements Belong in the Estate Planning Conversation

Estate planning and marital agreements are two sides of the same coin. One governs how assets are handled during life and at death, while the other shapes how assets are divided in separation or death.
1. Clarifying Separate vs. Community Property
In Texas, a community property state, assets acquired during marriage are typically considered jointly owned. A prenup or postnup can clearly define which assets should remain separate property, thus avoiding confusion, family conflict, or costly litigation later.
2. Ensuring Control Over Business Interests
If one spouse owns a business—especially in Southlake’s vibrant entrepreneur community—a marital agreement can protect the continuity of that business and ensure it stays within the intended hands.
3. Providing for Children from Previous Marriages
Blended families often use prenups or postnups to guarantee that children from prior marriages receive certain assets, even if the surviving spouse is still living.
4. Limiting Inheritance Disputes
When expectations are clearly set out in marital agreements, it can minimize surprises or challenges to a will or trust after death.
How Pre- and Post-Nups Interact With Wills and Trusts
One of the biggest misconceptions is that once you’ve drafted a will or trust, you’re protected. But here’s the catch: if your estate planning documents conflict with your marital agreement, it can result in a court battle or nullification of part of your estate plan.
For example:
- If your will leaves everything to your spouse, but your prenup limits their share, this conflict must be reconciled.
- If a postnup states certain assets remain separate, but your trust assumes joint ownership, the trust may not function as intended.
This is why a coordinated approach—in which your marital agreements and estate documents are reviewed and aligned—is essential.
Key Clauses to Consider in Estate-Focused Marital Agreements
If your goal is to integrate a marital agreement with your estate plan, make sure you include provisions that address:
- Spousal rights at death (elective share waivers, rights to residence, etc.)
- Clarification of separate vs. community assets
- Treatment of future inheritance
- Buy-sell terms for business or real estate
- Agreement to waive claims against the estate
These clauses are especially important in high-net-worth marriages or second marriages where expectations and legacy concerns are nuanced.
Case Example: Trophy Club Couple Blends Family and Philanthropy
A couple in Trophy Club recently came to Peabody Law with a second marriage and complex blended family. Through a well-drafted post-nuptial agreement, they protected each other’s separate property, while their trusts directed specific inheritances to their respective children—and earmarked assets for local charitable causes in Grapevine.
This multi-layered strategy allowed them to maintain financial independence while still building a legacy together.
Timing and Transparency: What Estate Planners Should Know
When integrating prenups or postnups into your estate plan:
- Review marital agreements regularly. Just like a will, a marital agreement may need to be updated as your financial picture changes.
- Use consistent language across all documents. Your trust, will, and marital agreement should reinforce—not contradict—each other.
- Be transparent with heirs when appropriate. Clear expectations reduce the risk of probate litigation.
Final Thought: Harmony, Not Hostility
Far from being cold or transactional, marital agreements can provide peace of mind for spouses, children, and future generations. When used properly, they foster honesty, reduce friction, and help everyone focus on what matters most: building a secure and meaningful legacy.
