When people think about estate planning, they often focus on wills, trusts and tax-efficient structures. However, an often-overlooked tool can play a significant role in protecting family wealth: the nuptial agreement. Whether entered into before marriage (a pre-nuptial agreement) or after marriage (a post-nuptial agreement), these agreements can help safeguard assets, protect inherited wealth and provide clarity regarding financial arrangements should a relationship later come to an end. They are particularly valuable where one party expects to receive a substantial inheritance, has accumulated family wealth, owns a business, or wishes to preserve assets for children from a previous relationship.

Protecting Non-Matrimonial Wealth

Under Scottish family law, assets acquired during a marriage are generally considered matrimonial property and may be subject to division on divorce. By contrast, inheritances and gifts received from third parties are typically excluded. Difficulties can arise, however, when inherited or gifted assets change form during the marriage. For example, inherited funds may be used to purchase a property, invest in a business or support wider family wealth planning. In certain circumstances, these assets can become intertwined with matrimonial property, creating uncertainty if the marriage later breaks down. A carefully drafted nuptial agreement can help preserve the distinction between matrimonial and non-matrimonial assets and reduce the scope for future disputes.

More Than Divorce Planning

Nuptial agreements can also play an important role in succession planning.

Under Scottish law, spouses may have rights to claim against an estate following death, even where a will is in place. In certain circumstances, a nuptial agreement can include provisions dealing with these rights, helping to ensure that a wider estate planning strategy is not undermined by unexpected claims. This can be particularly relevant in second marriages, blended families and situations where a party wishes to preserve assets for children from an earlier relationship.

A Valuable Risk Management Tool

One of the key lessons for advisers is that family law considerations should not be viewed in isolation from estate and tax planning. Transactions that make perfect sense from a tax or succession perspective can sometimes create unintended consequences if relationship breakdown is not considered. Wealth transfers, business restructuring and property acquisitions may all alter the legal status of assets in ways that are not immediately obvious. For that reason, nuptial agreements should often form part of the wider planning conversation. Taking advice at an early stage can help protect family wealth, provide certainty for all parties and reduce the risk of costly disputes in the future.

Good estate planning is not simply about passing wealth on efficiently – it is also about ensuring that wealth remains protected along the way.
