Love, Marriage & Money: Do I Need a Prenup?

Introduction

Anyone entering into a marriage with assets, business interests, family wealth, existing financial obligations or children from a previous relationship may have good reason to consider a prenuptial agreement.

A prenup can help an intending couple clarify their respective property interests, distinguish separate property from matrimonial property and establish how certain financial matters should be treated during the marriage and if the marriage subsequently ends.

In Kenya, prenuptial agreements are recognized under the Matrimonial Property Act, 2013, which allows intending spouses to enter into an agreement determining their property rights before marriage.

However, a prenup is not simply a document designed to "protect everything you own." Its effectiveness depends on how it is negotiated, drafted, executed and, ultimately, interpreted in light of Kenyan law.

What Is a Prenuptial Agreement?

A prenuptial agreement, commonly known as a prenup, is an agreement entered into by two people in contemplation of marriage.

It allows intending spouses to agree on how certain property and financial interests will be treated during the marriage and in the event of separation, divorce or another event affecting their property rights.

A prenup may address matters such as:

• assets owned by each party before marriage;
• businesses and company interests;
• investments;
• property acquired during the marriage;
• debts and financial liabilities;
• income generated from separate assets;
• treatment of jointly acquired assets;
• the effect of contributions made by either spouse;
• inheritance and estate-planning considerations; and
• spousal financial arrangements, to the extent permitted by law.

The agreement should be tailored to the circumstances of the particular couple. There is no single "standard" prenup that will be appropriate for everyone.

What Law Governs Prenuptial Agreements in Kenya?

The principal legislation is the Matrimonial Property Act, 2013.

Section 6(3) of the Act expressly permits parties to an intended marriage to enter into an agreement before the marriage to determine their property rights. Absent such an agreement, Section 6(1) provides that matrimonial property vests in the spouses according to each spouse's contribution towards its acquisition, and is divided between them if they divorce or the marriage is otherwise dissolved.

Critically, Section 6(4) gives either party the right to apply to court to have the agreement set aside — and gives the court the power to do so — if it finds the agreement was influenced by fraud or coercion, or is manifestly unjust. A prenup is therefore not an absolute shield; its terms remain subject to judicial oversight.

The Act also recognizes both monetary and non-monetary contributions to matrimonial property, and its provisions must be read alongside applicable constitutional, family and contract law principles.

A carefully drafted agreement should therefore distinguish between matters the parties can validly agree upon and matters that remain subject to the law and the court's jurisdiction.

Is a Prenup Only for Wealthy People?

No. A prenup may be particularly useful where one or both parties already own property or have significant financial interests, but substantial wealth is not a prerequisite.

For example, a prenup may be worth considering where:

• one party owns a home before marriage;
• either party owns a business or shares in a company;
• one party has substantial investments;
• either party has inherited or expects to inherit family property;
• one party has significant debts or financial obligations;
• either party has children from a previous relationship;
• the parties expect significant wealth creation during the marriage;
• one party is contributing substantially to a family business;
• the parties have substantially different financial circumstances; or
• the parties simply want greater clarity regarding their respective property rights.

The value of a prenup is therefore not necessarily the amount of wealth involved. It is often the clarity it creates before the marriage.

Why Consider a Prenuptial Agreement?

Marriage creates legal and financial relationships between spouses. A prenup allows an intending couple to discuss those issues deliberately before they become the subject of a dispute.

1. To Identify Property Owned Before Marriage. A person entering a marriage may already own land, houses, investments, shares, businesses or other valuable assets. A prenup can clearly identify those assets and record how the parties intend them to be treated, reducing uncertainty if the marriage subsequently breaks down.

2. To Protect Family and Inherited Wealth. Some people marry while holding property accumulated over generations or inherited from family members. A prenup can form part of a broader strategy for documenting and structuring those interests, particularly where the person wishes to preserve certain family assets for children or other beneficiaries. It should not, however, be treated as a substitute for proper estate planning.

3. To Clarify Business Interests. Business ownership can become complicated when spouses contribute to a business in different ways — for example, where one spouse owns a company before marriage and the other later becomes involved in its operations. A well-drafted agreement can address the parties' intended treatment of business interests and how subsequent contributions may affect those interests. This is especially relevant for entrepreneurs, professionals, family-owned businesses and shareholders.

4. To Reduce Uncertainty in the Event of Divorce. A matrimonial property dispute can be expensive, time-consuming and emotionally difficult. While a prenup cannot guarantee that litigation will never occur, a properly prepared agreement provides evidence of the parties' intentions and a framework for addressing property issues — so that important financial questions are not being worked out for the first time in the middle of a dispute.

5. To Address Different Financial Circumstances. Couples do not always enter marriage with equal financial positions. One person may have accumulated substantial assets while the other has limited assets but expects to make significant non-financial contributions. These differences can be discussed openly and addressed in an agreement consistent with Kenyan law.

Can a Prenup Protect Assets Acquired During Marriage?

This is where careful drafting matters most.

A prenup can establish the parties' intentions regarding different categories of property, but property acquired during a marriage cannot simply be labelled "separate" without considering the applicable law and the circumstances in which it was acquired.

The Matrimonial Property Act recognizes both monetary and non-monetary contributions to matrimonial property. Non-monetary contributions may include:

• domestic work and management of the matrimonial home;
• childcare;
• companionship;
• management of family business or property; and
• other forms of contribution recognized by law.

A prenup should not be drafted on the assumption that only the person who paid money towards an asset has an interest in it. It should instead carefully address how the parties intend their property arrangements to operate while recognizing the mandatory legal framework governing matrimonial property.

When Should a Prenup Be Signed?

Ideally, well before being legally married.

The closer an agreement is signed to the wedding date, the greater the potential for questions about whether one party genuinely entered into it voluntarily and with sufficient opportunity to understand its consequences — the exact grounds (coercion, fraud) on which a court can set an agreement aside under Section 6(4).

The parties should allow adequate time to:

• identify their respective assets and liabilities;
• disclose relevant financial interests;
• obtain independent legal advice;
• negotiate the terms;
• consider proposed amendments;
• understand the legal and financial consequences; and
• execute the final agreement voluntarily.

A prenup should not be presented as an ultimatum shortly before the wedding. The objective should be informed agreement, not pressure.

Independent Legal Advice Matters

It is strongly advisable for each intending spouse to obtain independent legal advice before signing a prenuptial agreement.

Independent advice gives each party an opportunity to understand:

• what property rights they may have under Kenyan law;
• what rights they may be giving up or modifying;
• the practical consequences of particular clauses;
• whether the agreement reflects their understanding of the arrangement; and
• whether further negotiation is appropriate.

It also provides a stronger basis for demonstrating the agreement was entered into knowingly and voluntarily — which matters directly if the agreement is later challenged.

Prenuptial Agreements and Children from Previous Relationships

A prenup can be particularly relevant where either party has children from an earlier relationship or marriage, with the intention of preserving certain pre-marital assets or family wealth for those children.

A prenup should, however, form part of a broader estate-planning strategy. A person who wants to protect assets for children should consider the interaction between:

• the prenuptial agreement;
• their Will;
• ownership structures;
• trusts, where appropriate;
• nominations and beneficiary arrangements; and
• applicable succession law.

A prenup and a Will should be reviewed together, not prepared in isolation.

Prenuptial Agreements and Wills: Why Both Matter

A prenuptial agreement deals primarily with the parties' property rights and financial arrangements in the context of marriage. A Will deals with the distribution of a person's estate after death. The two documents should work together. After entering into a prenup, it is prudent to review an existing Will, or prepare one where none exists. The Will should also be reviewed periodically, particularly following:

• acquisition or disposal of significant property;
• birth or adoption of children;
• changes in business ownership;
• changes in marital circumstances;
• significant changes in wealth; or
• other major changes in family circumstances.

Can a Prenup Be Challenged?

Yes. A prenuptial agreement is not automatically immune from challenge simply because it has been signed. Under Section 6(4) of the Matrimonial Property Act, a court may set aside a prenuptial agreement if it finds that the agreement was influenced by fraud or coercion, or that it is manifestly unjust. In practice, this means courts look at:

• whether the agreement was entered into voluntarily;
• whether there was undue influence or coercion;
• whether the parties had adequate opportunity to obtain legal advice;
• whether there was sufficient financial disclosure;
• whether the terms are clear and properly understood; and
• whether the outcome the agreement produces is manifestly unjust in the circumstances.

This is why how the prenup is prepared can be as important as what it says.

What Should a Prenuptial Agreement Contain?

There is no universal template. Common provisions may include:

• Identification of the parties and their intended marriage;
• Disclosure and schedules of existing assets and liabilities;
• Identification of separate property;
• Treatment of property acquired during marriage;
• Business and company interests;
• Treatment of income and returns from separate assets;
• Treatment of jointly acquired property;
• Commingling of separate and matrimonial assets;
• Debts and financial liabilities;
• Spousal financial arrangements, subject to applicable law;
• Estate planning and inheritance considerations;
• Dispute resolution mechanisms;
• Governing law and jurisdiction; and
• Execution and other formal requirements.

The drafting should be sufficiently precise to avoid creating uncertainty about what the parties actually intended.

A Prenup Should Not Be a One-Sided Document

One of the biggest mistakes is approaching a prenup as a mechanism for one spouse to "protect everything" while leaving the other with no meaningful protection. A one-sided agreement is also more exposed to a "manifestly unjust" challenge under Section 6(4).

A strong agreement should instead reflect informed and balanced negotiations — for example, addressing:

• what happens to property acquired jointly;
• how contributions will be recognized;
• how business interests will be treated;
• what happens where one spouse leaves employment to care for children;
• how jointly incurred debts will be handled;
• how separate property will be treated if it is used for family purposes; and
• how disputes will be resolved.

The goal is not to minimize the other spouse's rights. The goal is to create clarity around the financial relationship between the parties — clarity that is also more likely to survive judicial scrutiny.

How We Can Help

We advise intending spouses on the preparation, negotiation and review of prenuptial agreements under Kenyan law.

Our approach is to understand the couple's individual financial circumstances, identify the assets and interests that require consideration, explain the applicable legal framework including the grounds on which an agreement can later be set aside and assist the parties in developing clear and workable terms.
