Postnuptial Agreements

A postnuptial agreement or postnup —  is an agreement made after a couple marries — it is a valuable legal tool for wealthy individuals wishing to have financial certainty in a marriage. While similar in effect to a prenuptial agreement, it can be particularly useful when financial circumstances change or when a prenup wasn’t signed. 

Wealth can grow substantially after marriage — through business success, inheritance, or investments. A postnup allows high-net-worth individuals to ring-fence assets after those assets are acquired, providing clear terms for division in case of divorce.


Why choose a postnup?



 ✔️ Protect business interests
✔️ Safeguard personal and family assets
✔️ Clarify financial expectations
✔️ Reduce future conflict and legal costs


Strengthening Legal Certainty

Since the Radmacher v Granatino case in 2010, courts in England and Wales are far more likely to uphold nuptial agreements if:

  • Both parties received independent legal advice
  • The agreement was entered into freely and with full disclosure
  • The terms are fair and meet basic needs

A postnup done correctly can offer substantial legal certainty, especially when combined with estate and tax planning.

Protecting and Ringfencing Wealth Accumulated During the Marriage

Wealth can grow substantially after marriage — through business success, inheritance, or investments. A postnup allows high-net-worth individuals to ring-fence assets after those assets are acquired, providing clear terms for division in case of divorce.


Financial situations evolve. A postnup can update or reinforce an existing prenup — for example, after the birth of children, a business sale, or a change in residence. Courts may give a well-drafted postnup more weight than a decades-old prenup.


For individuals expecting or receiving significant inheritances, or those involved in family businesses or trusts, a postnup can clearly separate personal or inherited wealth from matrimonial assets.  This is especially popular where families have children from previous relationships and a party wishes to specifically ringfence an inheritance for those children.
