What Is a Prenuptial Agreement?

prenuptial agreement (also called a premarital agreement) is made before marriage to outline how property, assets, and debts will be divided if the marriage ends.
Prenups are particularly valuable when:

  • One spouse owns a business or professional practice

  • Either spouse has significant assets or inheritance

  • There are children from a prior relationship

  • One spouse plans to pause a career to support the family

By clarifying financial expectations before marriage, couples can avoid disputes and protect what they’ve built.


What Is a Postnuptial Agreement?

postnuptial agreement is created after marriage but serves the same purpose — to clearly define how assets and debts will be handled if the relationship ends.
Postnups are useful when:

  • Financial circumstances change after marriage

  • One spouse inherits or acquires new property

  • A business grows or changes ownership

  • A couple wants added peace of mind and structure


Why You Might Want a Prenup or Postnup

Many people think prenups are only for the wealthy, but that’s not true. These agreements can protect anyone who wants financial clarity and fairness.
You may want to consider one if you:

  • Own real estate, a business, or significant investments

  • Have children from a previous marriage and want to preserve their inheritance

  • Expect to receive future assets, such as an inheritance or family trust

  • Want to prevent future disagreements over finances or debt

  • Value transparency and want to build trust through open communication

A prenup or postnup isn’t about mistrust — it’s about planning responsibly and protecting your future together.


Why These Agreements Build Trust

Having clear expectations about finances reduces misunderstandings and strengthens relationships.
Prenuptial and postnuptial agreements help couples:

  • Encourage open conversations about money

  • Prevent financial surprises and resentment

  • Protect family businesses and legacies

  • Save time, money, and emotional strain if divorce occurs


Legal Requirements in Texas for a prenup or postnuptial 

To be enforceable under Texas law, a prenup or postnup must be:

  1. Voluntary — signed without pressure or coercion

  2. Fully disclosed — both parties must share their assets and debts

  3. Fair and reasonable — not grossly one-sided

  4. In writing and signed — oral agreements are not enforceable

Because these agreements must meet strict legal standards, it’s essential to have an experienced Dallas family law attorney prepare or review your document.
