How Is a Mortgaged Home Divided in Divorce?

The Regime of Participation in Acquired Property and the Mortgaged Home

Since 2002, the Turkish Civil Code applies the regime of participation in acquired property by default unless the spouses choose another regime by marital agreement (Art. 202). Under this regime, income earned during the marriage through work, property purchased with that income, and anything acquired in its place count as acquired property (Art. 219); property received by inheritance or gift, and rights closely tied to the person, are personal property (Art. 220). Where it cannot be shown which category a given asset belongs to, the law presumes it is acquired property (Art. 222) — a presumption that, in practice, works in favour of the claiming spouse.

Why the Date the Property Regime Ends Matters

The critical point in the liquidation calculation is the date the property regime ends. In divorce, this is not the date the divorce judgment becomes final, but the date the divorce action was filed with the court (Art. 225). Instalments paid before this date are included in the liquidation; those paid afterwards are treated differently.

The Difference Between Marriages Before and After 2002

For spouses married before 1 January 2002 who did not choose another regime by that date, separation of property applied to the period up to that date; property acquired during that period may give rise to a contribution-share claim under general principles rather than a participation claim. Property acquired after 2002 falls directly under the regime of participation in acquired property.

Added Value, Value-Increase Share, and Participation Claim: Three Distinct Concepts

These three concepts are often confused. Added value is what remains of an asset's value at liquidation once the debts attached to it are deducted. A participation claim is the other spouse's right to half the added value of acquired property, and applies to a home bought during the marriage (Articles 231 and 236). A value-increase share, by contrast, is a separate right available where income earned during the marriage contributed to a spouse's personal property — a home bought before the marriage, for instance — claimed in proportion to that contribution (Art. 227).

How Is the Division of a Mortgaged Home Calculated?

Under settled Court of Cassation practice, liquidating a mortgaged property first requires determining the loan balance still outstanding at the date the property regime ended. The proportion this balance bears to the total purchase price is then calculated, and that proportion is applied to the property's current market value at the date of liquidation.

The Calculation Method, Step by Step

Step	What Is Done
1	The outstanding loan balance at the date the property regime ended (the filing date) is established
2	The proportion of this balance to the property's total purchase price is calculated
3	That proportion is applied to the property's current market value at the date of liquidation/judgment
4	The resulting amount is deducted from the current market value to arrive at the net "added value"
5	Half of the added value is calculated as the other spouse's participation claim

A Worked Example

The figures below are simplified purely to illustrate the method; a real file requires expert examination.

Item	Amount
Purchase price of the home	1,000,000 TL
Loan balance outstanding at filing date	300,000 TL (30%)
Market value of the property at liquidation	4,000,000 TL
Balance reflected in current value (30%)	1,200,000 TL
Net added value (4,000,000 − 1,200,000)	2,800,000 TL
The other spouse's participation claim (half)	1,400,000 TL

How the Formula Is Applied in Case Law

In a series of judgments, the 8th Civil Chamber of the Court of Cassation has emphasised that, for mortgaged property, the period to which payments to the lender relate, the amount paid, and the number of instalments must be taken into account, and that loan instalments not yet due should be included in the liquidation by applying their proportion to the property's current value. The full list of these decisions appears at the end of this article.

A Spouse Without Income Can Still Be Entitled to a Share

A common misconception is that a spouse who did not actually pay the loan instalments has no claim on the home at all. In fact, under the regime of participation in acquired property, the participation claim arises directly from the law.

The Legal Basis for the Participation Claim

A spouse claiming a participation share need not have had an income or have contributed directly to acquiring the property. This right over property acquired during the marriage is an automatic consequence of the statutory property regime.

The Position of a Homemaker Spouse

The same principle applies to a spouse who managed the household and had no direct income of their own; the law does not limit the contribution spouses make to one another to financial contributions alone. A participation claim should not be abandoned on the assumption that "I never worked, so I have no right."

What About a Home Bought Before the Marriage?

Where a home was purchased before the marriage, it is, as a rule, personal property and not subject to liquidation. However, because instalments paid during the marriage come from acquired income, the other spouse may acquire a separate claim over the value increase those payments produced.

How Is the Value Increase Calculated for Personal Property?

What is claimed here is not half of the whole property, but a value-increase share proportionate to the instalments paid during the marriage relative to the total price (Art. 227); the calculation method resembles the formula above, but what is ultimately shared is the increase in value attributable to the contribution, not the property as a whole.

Does It Matter Whose Name Is on the Title Deed?

No. The title deed only shows the apparent owner; a participation claim or value-increase claim arises independently of whose name appears on it, based on the nature of the asset and the source of the payments. A property registered to one spouse alone does not, by itself, bar the other spouse's claim.

Loan Instalments Paid After the Divorce

A significant portion of a mortgage often continues to be paid after the divorce action is filed. Payments made after the property regime ends are treated differently.

Whose Debt Are Post-Filing Instalments?

Under Court of Cassation practice, loan debt relating to the period after the property regime ends is treated as the personal debt of the spouse who pays it during that period, and those payments become that spouse's personal property; they are not included in the liquidation calculation. Calculating the claim over the whole property without accounting for instalments paid after filing is therefore incorrect.

Does Being a Loan Guarantor Affect the Division?

Being named as a guarantor or joint debtor on the loan agreement does not, by itself, create or extinguish a participation claim; what matters is not the guarantee but when the home was acquired and during which period, and from whose income, the payments were made.

As of Which Date Is the Property's Value Determined?

One of the most contested questions in dividing a mortgaged home is which date's value is used. Under current Court of Cassation practice, the property's value is not fixed as of the date the divorce action was filed, but as of the current market value closest to the date of judgment.

How Is Market Value Established?

Market value is established by a court-appointed expert — generally a real estate valuation specialist — by reference to comparable sales and the property's specific characteristics (location, floor area, building age, floor level, and the like). A party who considers the report inadequate may challenge it.

The Effect of a Mortgage or Other Encumbrance on Value

Encumbrances on the property arising from the loan, such as a mortgage, are also taken into account when establishing market value; the expert should determine a realistic value that reflects these encumbrances rather than the property's "clean" value.

Does Interest Apply to the Participation Claim?

Where the participation claim requires separate litigation or enforcement proceedings to collect, Court of Cassation practice generally applies statutory interest from the date of judgment. Because the starting date and rate of interest can vary with the facts of the file, it is important to state the interest claim explicitly in the pleading rather than assume a fixed rule.

The Process for a Liquidation of the Property Regime Action

Dividing a mortgaged home is heard as a separate action from the divorce itself, generally brought after the divorce judgment becomes final.

Which Court Hears the Action?

An action for liquidation of the property regime is heard before the family court, or, where none exists, before the civil court of first instance sitting as a family court.

What Documents Are Required?

The process generally calls for the title deed, the loan agreement and payment schedule, bank statements, and, where available, other documents relating to the purchase such as a preliminary sale agreement or payment receipts. Gathering these documents in full before filing helps the process move faster.

How Does the Expert Examination Work?

The court generally has the property's current value and the liquidation calculation examined by experts in real estate valuation and financial consulting; the parties may submit objections to the expert report in writing, and the court may order a supplementary report or a fresh examination if it considers this necessary.

Common Mistakes

• Concluding, from the title deed alone, either "it's not in my name, so I have no claim" or, conversely, "it's in my name, so it's entirely mine"
• Assuming that being a loan guarantor or joint debtor by itself creates or extinguishes a claim
• Claiming a share of the whole property without accounting for instalments paid after the divorce
• Confusing "participation claim" with "value-increase share" for a home bought before the marriage
• Assuming the property's value is fixed as of the filing date — the value actually used is the current value closest to the date of judgment

Conclusion

Dividing a mortgaged home in divorce is not a simple matter settled by the title deed alone. The period in which loan payments were made, the balance outstanding at the date of divorce, the property's current value, and the parties' rights under the property regime must all be assessed together. Case law shows that technical calculation plays a major role in dividing mortgaged homes and often calls for expert examination. Legal advice in property-regime disputes is accordingly important to avoid a loss of rights.
