Introduction

In Kenya’s dynamic legal and social landscape, married couples are increasingly seeking clarity and security regarding their property rights. One of the legal instruments gaining attention in this regard is the post-nuptial agreement—an agreement entered into by spouses after marriage, outlining how their property will be owned or divided. But are post-nuptial agreements recognized and enforceable under Kenyan law? The answer is yes.

At F.M. Muteti & Co. Advocates, a leading law firm in Nairobi serving clients across Kenya and in the diaspora, we regularly advise on matrimonial property matters, including the drafting and enforcement of post-nuptial agreements.

What Is a Post-Nuptial Agreement?

A post-nuptial agreement is a legally binding contract made between spouses during the subsistence of a marriage, detailing how property should be owned, managed, or divided—either during the marriage or in the event of separation or divorce. Unlike pre-nuptial agreements which are signed before marriage, post-nuptial agreements are made after a couple is already legally married.

Legal Basis in Kenya

While the Matrimonial Property Act, 2013 does not explicitly reference “post-nuptial agreements,” it supports their enforceability under general principles of contract law. Section 6(3) of the Act allows spouses to enter into agreements that determine their property rights. Courts in Kenya have affirmed that post-nuptial agreements are valid, provided they are entered into freely, with full disclosure, and without fraud or coercion.

Judicial Recognition of Post-Nuptial Agreements in Kenya

1. DNK v KM [2021] eKLR

In this case, the High Court upheld a post-nuptial agreement between a husband and wife that clearly defined their separate property interests. The court emphasized that such agreements, though not specifically provided for in statute, are enforceable under contract law principles. The agreement was recognized as valid because it was signed voluntarily and there was no evidence of coercion or unfairness.

2. Matrimonial Cause E022 of 2021 (QMK v DAW)

This matter involved a post-nuptial settlement where both parties had legal representation and willingly agreed on the division of assets. The court recognized the agreement as binding, stating that unless fraud, coercion, or manifest injustice is proven, the agreement must be respected.

Why You May Need a Post-Nuptial Agreement in Kenya

Post-nuptial agreements can be especially useful for:

  • Protecting pre-marital or inherited assets
  • Clarifying financial responsibilities in a blended family
  • Structuring asset ownership for business or investment purposes
  • Preventing lengthy property disputes in the event of separation or divorce

These agreements are also favored by spouses who wish to strengthen transparency and accountability in the marriage, especially when circumstances such as financial fortunes, children, or external risks evolve during the marriage.

Requirements for a Valid Post-Nuptial Agreement in Kenya

To be enforceable in Kenya, a post-nuptial agreement must:

  • Be in writing and signed by both spouses;
  • Be entered into voluntarily, without pressure or intimidation;
  • Reflect full disclosure of all assets and liabilities;
  • Be fair and not grossly one-sided;
  • Be witnessed and, preferably, drafted with the assistance of independent legal counsel.

Conclusion

Post-nuptial agreements are not only recognized in Kenya but are also enforceable when properly executed. They offer a smart and practical way for married couples to structure their property rights and avoid future legal conflicts. Kenyan courts have repeatedly upheld such agreements as valid contracts, especially when fairness, voluntariness, and full disclosure are demonstrated.
