Dallas Marital Agreement Litigation Attorney

Premarital and post-marital agreements are designed to create certainty, but disputes can arise when a marriage ends and substantial property rights depend on what the agreement says and whether it can be enforced.

In high-net-worth divorces, those disputes can affect businesses, real estate, investment accounts, trusts, executive compensation, inherited wealth, and other significant assets. A disagreement over a single provision may materially change the size or composition of the marital estate.

Brad M. LaMorgese represents clients in Dallas-Fort Worth and throughout Texas in litigation involving premarital and post-marital agreements. His broader work with marital agreements involving significant assets and complex financial structures includes both drafting agreements and litigating their validity, interpretation, and effect.

These cases require more than reading the document. The court may need to examine how the agreement was negotiated, what financial information was exchanged, whether amendments were made, how property was handled during the marriage, and whether the agreement applies to assets that may look very different years later.

When Marital Agreement Litigation Arises

Disputes involving marital agreements can surface in several different ways.

One spouse may argue that the agreement should not be enforced at all. In another case, both spouses may agree that the contract is valid but disagree about what a particular provision means. A dispute may also concern whether an asset is covered by the agreement, whether a later transaction changed the property’s character, or whether the parties modified their original arrangement.

Common issues include:

• Whether the agreement was signed voluntarily
• Whether required financial disclosure was provided
• Whether disclosure was validly waived
• Whether a spouse had adequate knowledge of the other party’s property and obligations
• Whether a provision is ambiguous
• Whether an amendment or later agreement changed the original terms
• Whether particular property falls within the agreement
• Whether replacement or reinvested assets remain subject to the agreement
• Whether the parties’ conduct during marriage affects interpretation
• Whether the agreement addresses reimbursement or other financial claims

In substantial estates, the litigation may involve both contract interpretation and detailed financial evidence.

Challenging a Texas Premarital Agreement

Texas Family Code Section 4.006 governs enforcement of premarital agreements.

A party challenging enforcement may establish that the agreement was not signed voluntarily. The statute also provides a separate basis involving an agreement that was unconscionable when signed and specified circumstances concerning fair and reasonable disclosure, written waiver of further disclosure, and adequate knowledge of the other party’s property or financial obligations.

The statute also states that unconscionability is decided by the court as a matter of law and that the remedies and defenses provided in the section are exclusive.

Those provisions make the factual record surrounding negotiation and execution particularly important.

Voluntariness Can Become a Central Issue

A claim that an agreement was signed involuntarily is often highly fact-specific.

The court may examine the circumstances surrounding execution, including the timing of the agreement, the negotiation process, access to counsel, communications between the parties, and any alleged pressure or threats.

Texas appellate courts have emphasized that difficult circumstances alone do not necessarily establish involuntariness. In one reported case, the court rejected a challenge based on pregnancy and the threat that the marriage would not occur, concluding that the record did not establish involuntary execution under the statute.

The practical significance is that voluntariness should be evaluated based on the actual evidence rather than broad characterizations of the negotiation.

Potential evidence may include:

• Drafts of the agreement
• Emails and text messages
• Correspondence between attorneys
• Engagement letters
• Calendars and wedding-related timing
• Testimony concerning negotiations
• Records showing when financial information was provided
• Evidence concerning access to independent counsel

The strength of a challenge or defense often depends on how clearly the historical record can be reconstructed.

Financial Disclosure Can Be Heavily Litigated

In substantial estates, disclosure issues can become complicated quickly.

A spouse may argue that the financial information provided before signing was incomplete or misleading. The other side may contend that the information was sufficient, that further disclosure was waived in writing, or that the challenging spouse already possessed adequate knowledge of the relevant assets and obligations.

The inquiry may involve far more than whether a balance sheet existed.

Relevant evidence can include:

• Business ownership information
• Investment and retirement accounts
• Real estate
• Trust interests
• Partnership interests
• Executive compensation
• Significant liabilities
• Personal guarantees
• Tax returns
• Financial statements
• Valuation information available at the time

The question is not simply whether the estate was large. The litigation focuses on the statutory requirements and the evidence showing what was disclosed, waived, or known when the agreement was executed.

Post-Marital Agreement Challenges Follow a Similar but Separate Statutory Framework

Texas Family Code Section 4.105 governs enforcement of partition and exchange agreements and agreements concerning income or property derived from separate property.

As with premarital agreements, a party may challenge enforcement based on involuntary execution. The statute also contains an unconscionability framework tied to disclosure, written waiver, and adequate knowledge.

The factual setting can be different, however, because spouses negotiating an agreement during marriage may already own substantial community property together.

A dispute over a post-marital agreement may therefore involve both the negotiation process and a detailed analysis of property that existed when the spouses changed their ownership rights.

Interpretation Disputes Can Matter Even When the Agreement Is Valid

Not every marital agreement case concerns enforceability.

Sometimes both parties agree that the contract is binding but disagree about what it means.

Interpretation disputes may involve phrases that seemed clear when written but become difficult to apply years later. Assets may have changed names, been transferred into new entities, or been sold and replaced.

Questions may include:

• Does the agreement cover appreciation in a separately owned business?
• How are distributions treated?
• Does replacement property remain separate?
• What happens to proceeds after an asset is sold?
• Does a provision apply to a newly formed entity?
• How should a clause governing income be applied?
• Does a later agreement modify an earlier one?
• Is a particular provision ambiguous?

These disputes can require both legal interpretation and evidence explaining the financial history of the property.

Business Interests Often Create Contract and Valuation Issues at the Same Time

Business-related marital agreements can become especially complicated because ownership, characterization, and value are separate questions.

An agreement may establish that a business interest is one spouse’s separate property. That does not necessarily resolve every issue concerning distributions, compensation, reimbursement, or other financial rights arising during the marriage.

Likewise, the agreement may define ownership clearly while leaving the parties to dispute the current value of the company.

When substantial business interests are involved, the litigation may require both interpretation of the marital agreement and analysis of the company’s value in the divorce.

Keeping those issues separate helps avoid treating the agreement as though it answers questions it was never designed to resolve.

Separate Property and Tracing Can Still Matter

A valid marital agreement does not always eliminate the need for financial tracing.

An agreement may classify certain categories of property as separate, but the parties may still disagree about whether a particular asset falls within that category.

For example, separately identified funds may have been transferred through several accounts before being used to acquire another asset. A business interest may have been reorganized. Inherited funds may have been invested alongside other property.

In those situations, tracing the history of disputed assets can become part of the contract litigation.

The agreement establishes the rule, while the financial evidence may determine whether the asset at issue fits within that rule.

Amendments and Later Agreements

Marital agreements are not always static.

Spouses may amend, revoke, replace, or supplement an earlier agreement. Estate-planning documents, property agreements, business transactions, or later marital agreements may create additional issues.

Litigation can arise over whether a later document:

• Validly amended the original agreement
• Revoked certain provisions
• Addressed only specific assets
• Created inconsistent obligations
• Changed the treatment of future income
• Altered rights concerning a business
• Affected property acquired after execution

The documents must be read together where appropriate, and the formal requirements governing modification or revocation must be considered.

The Parties’ Conduct During Marriage Can Become Relevant

Years may pass between signing a marital agreement and litigating it.

During that time, the spouses may handle property in ways that differ from what one side later contends the agreement required.

They may jointly title assets, move money between accounts, operate businesses together, acquire property through entities, or enter additional financial arrangements.

The legal effect of that conduct depends on the agreement and applicable law. It should not automatically be assumed that informal behavior changes a written contract.

But the history may still become relevant to questions of interpretation, characterization, tracing, or whether later agreements were created.

Discovery in Marital Agreement Litigation

These cases often require discovery focused on events that occurred many years earlier.

The most important evidence may not be the current financial records. It may be the documents showing what happened when the agreement was negotiated and how property was handled afterward.

Discovery may involve:

• Original and revised drafts
• Attorney correspondence
• Financial disclosures
• Emails and text messages
• Estate-planning documents
• Business records
• Trust records
• Bank and investment statements
• Property records
• Tax returns
• Prior agreements or amendments
• Communications concerning execution

Because some evidence may be decades old, identifying and preserving available records early can be important.

Litigation Strategy Depends on the Nature of the Dispute

A marital agreement case should not be treated as though every issue rises or falls together.

Counsel should identify whether the real dispute concerns:

• Enforceability
• Interpretation
• Property characterization
• Financial disclosure
• Voluntariness
• Amendment or revocation
• Tracing
• Valuation
• Reimbursement
• Application of the agreement to a particular asset

That distinction can affect discovery, motion practice, financial analysis, and trial strategy.

A case challenging the entire agreement may require a very different approach from one involving a narrow interpretation issue affecting a single asset.

Summary Judgment and Pretrial Rulings May Shape the Case

Some marital agreement disputes involve issues that may be addressed before the broader divorce case is tried.

Questions of contract interpretation, statutory enforceability, or the legal effect of particular provisions may become the subject of dispositive motions or separate hearings.

Resolving those issues early can materially alter the remainder of the case.

For example, an enforceability ruling may determine whether substantial property will be governed by the parties’ contract or ordinary Texas marital-property rules.

That makes the sequencing of litigation important. Counsel should consider not only the merits of the agreement dispute but also when and how the issue should be presented to the trial court.

Appellate Preservation Can Be Particularly Important

Marital agreement litigation often presents discrete legal questions that may later become appellate issues.

The Texas Supreme Court has emphasized that courts should enforce agreements according to the provisions the parties actually adopted rather than rewriting them to add terms they could have included themselves.

When significant property rights depend on an enforceability or interpretation ruling, preservation becomes important.

The trial record may need to clearly reflect:

• The agreement and relevant amendments
• The asserted statutory challenge
• Evidence supporting or opposing voluntariness
• Disclosure and waiver evidence
• Competing interpretations
• Evidentiary rulings
• Requested findings or other necessary trial-court rulings

Brad’s appellate background informs his approach to high-stakes agreement disputes at the trial level. His work in complex appellate and post-trial family law matters provides perspective on how significant legal issues should be developed and preserved before an appeal ever begins.

Litigation Involving High-Net-Worth Agreements

The economic consequences of a marital agreement dispute can be substantial.

An agreement may determine the treatment of a closely held company, inherited assets, trust distributions, investment portfolios, executive compensation, real estate, or other property accumulated over decades.

For that reason, the agreement dispute should be evaluated in the context of the entire marital estate.

A ruling that changes the characterization of one major asset can alter settlement positions, valuation needs, discovery priorities, and the overall property division.

Where the agreement affects substantial wealth, litigation strategy should account for both the contractual issues and the financial consequences of each possible ruling.
