Come we stay property rights in Kenya can become far more complicated than many couples expect when a relationship ends, one partner dies, or a jointly funded property suddenly has to be divided.

For years, many Kenyans have assumed that if a couple lives together long enough, has children together, buys property and presents themselves publicly as husband and wife, the law will automatically treat them as married.

That assumption is dangerous.

Kenyan law does not recognise “come we stay” as a separate statutory form of marriage. The Marriage Act recognises specific systems of marriage, including Christian, civil, customary, Hindu and Islamic marriages.

However, Kenyan courts can in limited circumstances presume that a marriage existed after prolonged cohabitation.

The Supreme Court clarified this in MNK v POM. It held that cohabitation alone is not enough. A person asking a court to presume a marriage must show factors including long cohabitation, legal capacity to marry, an intention to marry, mutual consent and that the parties held themselves out publicly as husband and wife. The Court also warned that the doctrine should be used sparingly and that marriage should not be imposed on people who never intended to marry. Read the Supreme Court decision on presumption of marriage through Kenya Law.

This becomes extremely important when property is involved.

A couple may live together for 10 years, raise children and even pay for the same house, yet find that their legal rights are very different from what they assumed.

Here are 10 questions every Kenyan buying property with a spouse, partner, lover, friend or business associate should understand.

1. When Does “Come We Stay” Become a Legally Recognised Marriage in Kenya?

There is no automatic rule saying:

“If you live together for X years, you are legally married.”

That is one of the biggest misconceptions surrounding come we stay property rights in Kenya.

The Supreme Court has laid out strict conditions for a presumption of marriage.

A court may consider whether:

• The couple lived together for a substantial period
• Both people had the legal capacity to marry
• They intended to marry
• Both consented to the marital relationship
• They held themselves out to the public as husband and wife

The person claiming that a marriage existed carries the burden of proving it on a balance of probabilities.

The Court went further and cautioned that the doctrine of presumed marriage should be used sparingly because many adults deliberately choose to cohabit without intending to marry.

This means:

Living together does not automatically convert a relationship into marriage.

Having children together does not automatically do so either.

Neither does sharing rent, buying furniture or calling each other husband and wife casually.

The legal consequences therefore become unpredictable when couples leave their relationship status undefined.

For property buyers, uncertainty is particularly risky because matrimonial-property rights apply to spouses.

If your entire property claim depends on proving years later that a marriage should be presumed, you are already entering a more complicated legal dispute than someone whose marital and ownership status was properly documented.

2. If an Unmarried Couple Takes a Joint Mortgage and Breaks Up, Who Gets the House?

This is one of the most important questions couples should answer before taking the mortgage.

A joint mortgage actually involves two separate issues:

Who owes the bank?

and

Who owns the property?

Those are not always the same question.

The lender’s rights are governed by the mortgage or charge documents and the loan agreement.

A relationship ending does not automatically rewrite a loan contract.

If both partners signed borrowing obligations, they should not assume that simply moving out or agreeing privately that one person will keep the house automatically releases the other person from obligations to the lender.

Any release, refinancing or transfer normally needs to satisfy the lender and the relevant legal requirements.

Ownership, meanwhile, depends on factors including:

• How the title is registered
• Whether the parties are joint owners or owners in defined shares
• What their purchase agreement says
• What each person contributed
• Whether a trust or other beneficial interest can be established

This is why unmarried couples should never rely on statements such as:

“We both know this house is 50/50.”

Put it in writing.

Before buying, document:

• Ownership percentages
• Deposit contributions
• Mortgage-payment responsibilities
• Repair and renovation contributions
• What happens if one person stops paying
• What happens if the relationship ends
• How one partner can buy the other out
• How the property will be valued
• What happens if the property has to be sold

A breakup agreement made after emotions have collapsed is much harder to negotiate than an ownership agreement made before the purchase.

3. Can a Partner Claim Property You Bought Before Marriage?

Potentially, but not simply because they moved into it.

The Matrimonial Property Act distinguishes property acquired before marriage from matrimonial property.

Generally, property acquired before marriage remains separate.

However, section 9 of the Matrimonial Property Act provides an important qualification: where one spouse contributes toward the improvement of property acquired before or during the marriage, that spouse can acquire a beneficial interest equal to the contribution made.

Kenyan courts have applied this principle where one spouse contributed to improvements on property originally belonging to the other spouse.

That contribution could become important where a spouse pays toward:

• Construction
• Major renovation
• Extensions
• Mortgage repayments
• Property improvement

The Act also recognises both monetary and non-monetary contribution.

Under the Matrimonial Property Act, contribution includes:

• Domestic work
• Management of the matrimonial home
• Childcare
• Companionship
• Management of family business or property
• Farm work

However, unmarried cohabitants should be more cautious.

If no marriage exists or can be legally presumed, matrimonial-property protections may not automatically apply in the same way.

That makes documentation even more important.

If you are putting substantial money into a property registered solely in your boyfriend’s or girlfriend’s name, do not simply assume:

“I have receipts, so I automatically own half.”

Get legal advice and formalise the ownership arrangement.

4. What If One Person Pays for the House and the Other Raises the Children?

This is where many couples misunderstand the law.

Financial contribution is important.

But it is not the only recognised contribution in a marriage.

The Matrimonial Property Act specifically recognises non-monetary contribution such as:

• Childcare
• Domestic work
• Management of the home
• Companionship
• Managing family property or businesses

This means a spouse who did not write the cheque for the deposit or make every mortgage payment is not automatically treated as having contributed nothing.

However, this does not mean every matrimonial property dispute automatically ends in a 50:50 split.

Section 7 of the Matrimonial Property Act links ownership to each spouse’s contribution.

Kenyan courts therefore assess the particular circumstances and evidence.

In JOO v MBO, the Supreme Court considered whether spouses automatically become entitled to equal proprietary shares after dissolution and reinforced the importance of contribution rather than treating 50:50 division as an automatic rule. Read the Supreme Court matrimonial-property decision on Kenya Law.

The practical lesson is:

The person earning the salary should not assume money is the only contribution that matters.

And the homemaking spouse should not assume 50% is guaranteed regardless of circumstances.

Both sides need evidence.

5. What Are the Biggest Legal Loopholes in “Come We Stay” Relationships?

The biggest risk is not necessarily a loophole in legislation.

It is uncertainty.

A cohabiting couple may never clearly establish:

• Whether they intended to marry
• Who owns what
• Whether property is joint
• What happens at death
• Whether contributions create ownership
• What happens after separation

That ambiguity becomes expensive once people stop cooperating.

Consider what happens if one partner dies.

The survivor may believe:

“We lived as husband and wife for 15 years, so I automatically inherit.”

But if the relationship was never formalised, the survivor may first need to establish their legal status or other rights before succession issues can even be resolved.

Similarly, if property is registered in only one person’s name, the other partner may have to prove beneficial ownership rather than simply pointing to a marriage certificate.

Common risks include:

• Property registered entirely in one person’s name
• No written agreement on contributions
• Mortgage paid from one partner’s account
• Renovations funded informally
• Property secretly transferred
• One partner dying without a will
• Disputes with children or relatives
• Property purchased through a company controlled by one partner

The solution is not to avoid buying together.

It is to document the relationship between money and ownership.

6. What Safeguards Should Lovers, Friends or Business Partners Put in Place?

This question extends far beyond romantic relationships.

Two friends can face exactly the same problem.

Suppose you and your best friend buy a KSh 20 million apartment.

You each contribute KSh 10 million.

But the title is registered only in your friend’s name.

Your friendship may be excellent today.

That does not mean the legal structure is sensible.

Before paying, agree in writing on:

Ownership

Who owns what percentage?

Contributions

Who is paying:

• Deposit
• Instalments
• Mortgage
• Service charges
• Repairs
• Taxes

Income

If the property earns rent, how is it divided?

Exit

What if one person wants to sell and the other doesn’t?

Buy-Out

How will one person’s interest be valued?

Death

What happens if one co-owner dies?

Default

What happens if one person stops paying?

Dispute Resolution

How will disagreements be handled?

Also ensure the title structure reflects what the parties actually intend.

Do not transfer substantial money simply because someone says:

“Trust me, we will sort the paperwork later.”

Property has a way of testing relationships.

The paperwork should come first.

7. Can Your Spouse Secretly Sell or Mortgage the Matrimonial Home?

Kenyan law provides important protection where the property is matrimonial property.

Section 12 of the Matrimonial Property Act states that an interest in matrimonial property in a monogamous marriage should not be sold, gifted, leased, mortgaged or otherwise alienated without the consent of both spouses.

Kenyan courts have treated spousal consent as important when matrimonial property is sold or charged.

The Land Registration Act also deals with spousal and matrimonial interests in land.

Read the Land Registration Act through Kenya Law.

However, buyers should not rely only on legal protection after a dispute occurs.

Practical protection matters too.

Spouses can consider:

• Ensuring ownership records are correct
• Keeping copies of title and charge documents
• Reviewing property searches periodically where appropriate
• Keeping evidence of contributions
• Making sure consent documents are genuine
• Obtaining legal advice promptly if they suspect an unauthorised transfer

If you suspect a spouse is attempting to dispose of matrimonial property secretly, seek legal advice immediately rather than waiting until the transaction is complete.

Courts can in appropriate circumstances issue orders restraining dealings with disputed property.

8. What Happens If Someone Buys Property With a Secret Lover While Still Married?

This can become legally complicated very quickly.

There may be at least three competing interests:

• The registered owner
• The legal spouse
• The person who claims to have financed or contributed to the property

The outcome will depend on facts such as:

• When the property was acquired
• Whose name appears on the title
• Source of funds
• Whether the property became matrimonial property
• Whether the legal spouse contributed
• Whether the third party can establish a beneficial interest
• Whether fraud or concealment occurred
• Whether the existing marriage was monogamous or potentially polygamous

One particularly important issue is legal capacity to marry.

The Supreme Court has held that a presumption of marriage requires legal capacity. Where a person is already in a subsisting marriage that prevents another marriage, that can defeat an attempt to establish a presumed marriage with a cohabiting partner.

So a secret lover should not assume:

“We lived together, therefore I am automatically a spouse.”

But the absence of spousal status does not necessarily make financial contributions disappear.

A person claiming an interest may still seek legal remedies based on the actual ownership arrangement, contributions or other applicable principles.

These cases are highly fact-sensitive and should be handled by a qualified advocate.

9. Who Gets to Stay in the Family Home After Separation?

Ownership and occupation are not always the same issue.

A property might be registered in one spouse’s name while the other spouse and children continue living there during or after separation.

That does not automatically resolve the final ownership shares.

Courts may need to address:

• Matrimonial-property rights
• Children’s welfare
• Occupation
• Protection from disposal
• Contribution
• Final division

In one Kenyan matrimonial-property case, the High Court recognised that property could be matrimonial even where registered in one spouse’s name and assessed both direct and non-monetary contributions.

The presence of children can also affect practical living arrangements, but children do not automatically transfer ownership of the property to one parent.

A registered owner should therefore be cautious about assuming:

“My name is on the title, so I can throw everyone out tomorrow.”

Equally, occupation of a house does not automatically mean the occupying spouse owns 50%.

If separation becomes hostile, obtain court orders or legal guidance rather than resorting to:

• Lock changes
• Forced evictions
• Secret sales
• Utility disconnections
• Threats

Property disputes can quickly become family, land and child-welfare disputes at the same time.

10. What Should Lovers, Friends and Married Couples Do Differently?

The answer depends on the relationship.

If You Are Buying With a Lover

Do not rely on the relationship.

Create a formal co-ownership agreement.

Specify:

• Contributions
• Ownership percentages
• Mortgage obligations
• Rental income
• Exit rights
• Buy-out procedure
• Death provisions

If you eventually marry, review the structure again.

If You Are Buying With a Friend

Treat the investment like a business transaction.

Document everything.

Have separate legal representation if necessary.

Do not allow friendship to replace contracts.

If You Are Buying a Matrimonial Home

Agree on ownership and financing before completion.

Understand how the title will be held.

Keep records of financial contributions.

Recognise that non-monetary contribution can also matter under matrimonial-property law.

And if one spouse owns the property before marriage, discuss what happens if the other spouse later pays for:

• Renovations
• Extensions
• Mortgage
• Major improvements

Silence does not create clarity.

What Counts as Matrimonial Property in Kenya?

The Matrimonial Property Act includes categories such as:

• Matrimonial home or homes
• Household goods and effects in the matrimonial home
• Other movable or immovable property jointly owned and acquired during marriage

Property acquired in one spouse’s name can still attract matrimonial-property claims depending on the circumstances.

The Act also creates presumptions relating to property acquired during marriage.

Where matrimonial property is acquired in one spouse’s name, there can be a rebuttable presumption that it is held in trust for the other spouse.

Where it is acquired in both names, there can be a rebuttable presumption that their beneficial interests are equal.

This is why title registration matters—but it may not always be the end of the inquiry.

Does the Constitution Guarantee a 50:50 Split?

No.

Article 45(3) of the Constitution provides that parties to a marriage are entitled to equal rights at the time of marriage, during marriage and at dissolution.

Read Article 45 of the Constitution through the Kenya Law Reform Commission.

But equal rights do not automatically mean equal ownership percentages in every asset.

Matrimonial-property division still depends heavily on the statutory framework and evidence of contribution.

This is why couples should stop treating:

“We are married”

as equivalent to:

“Everything automatically belongs to us 50:50.”

That is too simplistic.

Why Keeping Records Matters

Many property disputes become difficult because nobody kept evidence.

Imagine trying to prove 12 years later that you paid:

• KSh 2 million deposit
• KSh 3 million toward a mortgage
• KSh 4 million for construction
• KSh 1.5 million for renovation

using only memory and WhatsApp conversations.

Keep:

• Bank transfers
• Receipts
• Mortgage statements
• Sale agreements
• Construction contracts
• Renovation invoices
• Valuation reports
• Correspondence
• Title records

For married spouses, non-monetary contribution still matters.

But good documentation can make the financial part of the dispute considerably clearer.

What Happens If One Partner Dies?

Death can expose every weakness in an informal arrangement.

If a couple is formally married, succession law provides established categories of spouses and dependants.

If the relationship was informal, the surviving partner may first face a dispute about whether they were legally a spouse at all.

The Supreme Court’s strict approach to presumed marriage makes this particularly important. Cohabitation by itself is not enough.

Meanwhile, relatives may appear.

Children may assert inheritance rights.

The title may be registered in only one person’s name.

A mortgage may still be outstanding.

This is why couples with meaningful property interests should consider:

• Formalising ownership
• Making wills
• Reviewing beneficiary nominations
• Understanding joint ownership structures
• Keeping succession documents updated

Death is a poor time for a family to discover that nobody understood how the property was legally held.

Property Bought Before Marriage: Separate Does Not Always Mean Untouchable

A common statement is:

“I bought it before marriage, so my spouse can never have any claim.”

That is too broad.

Property acquired before marriage is generally separate property.

But if a spouse later contributes toward its improvement, section 9 of the Matrimonial Property Act can create a beneficial interest tied to that contribution.

A Kenyan High Court case involving inherited property in Karen recognised an interest for a spouse who had contributed to improvements even though the original property had come from the other spouse’s family.

This is why couples renovating or developing separately owned property should discuss ownership consequences before spending substantial money.

The Biggest Mistake: Paying First and Discussing Ownership Later

Property purchases often begin emotionally.

A couple says:

“We are building our future together.”

Two friends say:

“We’ll split everything equally.”

A boyfriend says:

“Let me register it in my name because the paperwork is easier.”

Years later, the relationship changes.

Suddenly the unanswered questions become:

• Who owns the land?
• Who owns the building?
• Who made the deposit?
• Who made the mortgage payments?
• Was the money a gift?
• Was it a loan?
• Was ownership supposed to be 50:50?
• Can one person sell?

The safest time to answer these questions is before the money leaves your account.

Come We Stay Property Rights in Kenya: A Practical Protection Checklist

Before buying property with another person:

1. Establish your legal relationship.
2. Confirm exactly how ownership will be registered.
3. Agree ownership percentages in writing.
4. Record each person’s deposit contribution.
5. Document mortgage responsibility.
6. Create a process for repairs and improvements.
7. Decide what happens if one person wants out.
8. Agree how the property will be valued in a buy-out.
9. Plan for death or incapacity.
10. Keep records of every substantial payment.
11. Use an independent property lawyer.
12. Do not assume love, marriage or friendship automatically resolves ownership.

Final Thoughts on Come We Stay Property Rights in Kenya

Come we stay property rights in Kenya are complicated because relationships and property law do not always move together.

You can feel married without necessarily being legally married.

You can pay for property without appearing on the title.

You can be the registered owner without necessarily having the only beneficial interest.

You can contribute to a home without ever making a direct bank transfer.

And you can live together for years without automatically creating a marriage.

The Supreme Court has made one point particularly clear:

cohabitation alone does not automatically create marriage.

For married couples, the Matrimonial Property Act recognises both monetary and non-monetary contribution.

For unmarried couples, friends and other co-investors, proper contracts and ownership structures become even more important.

The safest rule is simple:

Do not wait until the relationship fails to decide who owns the property.

Decide before you buy.

Document before you pay.

Verify before you transfer.

And where substantial property is involved, get independent legal advice before relying on assumptions about marriage, contribution or ownership.
