The house you want often feels out of reach on one salary. So many couples apply for a KPR (Kredit Pemilikan Rumah, an Indonesian bank mortgage) on joint income: the husband’s and wife’s earnings counted together.

This can raise the amount the bank will lend. The trade-off is that both of you are inside the loan, both in what the bank checks and in who is responsible for paying.

This guide is for married couples preparing a mortgage application who want to know what changes when incomes are combined.

How banks combine incomes

The bank adds up both spouses’ net income, then subtracts any instalments you are already paying. What remains is compared with the KPR instalment you are applying for.

The limit on instalments as a share of income is set by each bank’s policy. A common rule is that all instalments together stay at or below about a third of income. Some banks are looser, some stricter.

Worked example (illustrative numbers only): the husband earns Rp 6 million and the wife Rp 4 million, so joint income is Rp 10 million. A third of that is about Rp 3.3 million. If you still pay Rp 800 thousand a month on a motorbike loan, the room left for a KPR instalment is about Rp 2.5 million.

Not all income counts the same way. A fixed salary with payslips is the easiest to assess. Business income, commissions or freelance fees need more evidence, and some banks only count part of them.

Only income you can prove counts. Cash from a business that never passes through a bank account is hard for a bank to recognise. The bank may also verify each of your workplaces or businesses, so make sure what you write on the form matches the documents you hand in.

Usually only a husband and wife in a legal marriage, shown by the marriage book (buku nikah), can combine incomes. To estimate instalments at different loan amounts, use the KPR calculator.

Both of you are checked in SLIK OJK

When incomes are combined, the bank checks both spouses’ credit histories in SLIK (Sistem Layanan Informasi Keuangan), the credit information system run by OJK, Indonesia’s financial services authority. A bad record on one side can affect the joint application.

SLIK grades every credit facility on five collectability levels: 1 Lancar (current), 2 Dalam Perhatian Khusus (special mention), 3 Kurang Lancar (substandard), 4 Diragukan (doubtful) and 5 Macet (loss).

Before applying, each of you should check your record and talk about the results openly. Old credit cards, store instalment plans, or a loan you once guaranteed for someone else can show up there. How to request your report is in checking SLIK OJK before a mortgage.

If there are arrears, clear them first and give the record time to update. Applying while the record still shows problems is likely to end in a rejection.

Documents for two people

The list is basically the usual mortgage application requirements, prepared for both of you:

  • ID cards (KTP) for husband and wife, the family card (Kartu Keluarga) and the marriage book.
  • Tax numbers (NPWP) as the bank requests.
  • Proof of each income, such as payslips and an employment letter for employees.
  • Bank statements for the last several months from the accounts your income goes into.
  • Business documents for anyone self-employed, such as a business licence and sales records.
  • Statements for other instalments running in either of your names.

On a joint-income KPR, both of you sign the credit agreement. That means both of you are responsible for the instalments until the loan is paid off.

Even when only one income is used, the other spouse is usually asked for written consent. The reason is that a house bought during the marriage becomes joint property, and pledging it to the bank needs both spouses’ consent.

The house becomes joint marital property

Under Law No. 1 of 1974 on Marriage (UU No. 1 Tahun 1974), Articles 35 and 36, property acquired during a marriage is harta bersama, joint marital property. Acting on it, such as selling it or pledging it as collateral, needs the consent of both spouses.

This holds whatever name is on the certificate. A house in the husband’s name alone is still joint property if it was bought during the marriage. So selling it later, or using it to secure another loan, still needs the other spouse’s consent. When the house is sold, the PPAT (the official who makes land deeds) will ask for the marriage documents and the spouse’s signature or written consent.

Property each spouse brought into the marriage, and inheritances, stay with that spouse unless agreed otherwise. If the down payment comes from one spouse’s inheritance, keep the paper trail and talk to a notary, since the split could be disputed later. The full picture is in marital property when buying and selling a home.

If you have a marriage agreement

A marriage agreement (perjanjian perkawinan) can separate a husband’s and wife’s property. Since Constitutional Court Decision No. 69/PUU-XIII/2015, it can also be made during the marriage, not only before the wedding.

If you have a property separation agreement, show it to the bank at the start. It can change who is recorded as owner and borrower, and which documents are needed. Policies differ between banks, so ask directly.

One point matters for mixed-nationality couples. An Indonesian citizen married to a foreigner without a property separation agreement cannot hold a house on a Sertifikat Hak Milik (SHM, the strongest freehold title), because the foreign spouse would co-own the joint property.

Risks to talk through first

A KPR runs for years, and family circumstances can change along the way. Discuss these before you sign:

  • One income stops. Losing a job, falling ill, or deciding to stop work to care for children doesn’t cancel the instalment. In the worked example above, a Rp 2.5 million instalment would take more than half the wife’s salary if the husband’s income stopped. If you can, choose an instalment that one salary could carry for a few months, and build an emergency fund.
  • One of you dies. Ask the bank who is covered by the KPR life insurance, one of you or both.
  • Divorce. The house is still joint property to be divided, and in the bank’s eyes the debt still belongs to both of you until it is settled. Releasing one spouse from the loan needs the bank’s approval.
  • Hidden debts. They show up in SLIK sooner or later. Better to put them on the table before applying than to have the application rejected.

These conversations aren’t comfortable. But they are far easier now than once the problem has arrived.

Before you apply

  1. Check both SLIK records and clear small arrears first.
  2. Work out an instalment that’s comfortable for two, then test whether one salary could carry it for a while.
  3. Gather documents for both of you at once.
  4. Agree on whose name goes on the certificate, knowing it remains joint property either way.
  5. Ask the bank about life insurance for both of you, how it counts irregular income, and whether either spouse’s age limits the tenor.
  6. Keep proof of where the down payment came from, especially if part of it is an inheritance or a gift from family.
