Short Definition
A co-borrower is a second person who signs the home finance contract with the main borrower and whose income is combined with his to raise the possible finance amount, becoming obliged to the lender to repay as the contract provides, usually on a joint and several basis.
Overview
Legal Basis
Co-borrowing is governed by the Civil Transactions Law issued by Royal Decree No. M/191 dated 29/11/1444H: Article 222 (solidarity between debtors arises only by agreement or legal provision), Article 225 (the creditor may claim from all or any of the joint debtors) and Article 578 (definition of guarantee, distinguishing a guarantor from a co-borrower). The finance is subject to the Real Estate Finance Law (M/50), its regulation and the Responsible Lending Principles, and obligations and guarantees appear in credit records under Article 16 of the Implementing Regulations of the Credit Information Law.
Practical Example
Khalid earns SAR 8,000 and pays a SAR 1,500 car installment; alone, his obligations cap is 55% (SAR 4,400), leaving only about SAR 2,900 for a mortgage installment, i.e. finance of about SAR 472,000 at 5.5% over 25 years, not enough for a SAR 1,000,000 apartment. His wife Hind (salary SAR 9,000, no obligations) joins as co-borrower under the bank's joint-finance policy, so the bank considers combined income of SAR 17,000 and obligations of SAR 1,500. It approves SAR 900,000 with an installment of about SAR 5,526.79, bringing total obligations to about SAR 7,027, around 41% of joint income. The contract provides for joint and several liability, the finance is recorded in both credit records, and they agree in writing to register the apartment in both names equally, since signing the finance alone gives Hind no ownership share.
Common Mistakes
- ✗Believing a co-borrower doubles borrowing capacity, when his obligations are also added and the limits apply to the total.
- ✗Confusing a co-borrower with a guarantor: the first is a principal debtor, the second pays only if the debtor does not.
- ✗Assuming signing the finance gives an ownership share, when ownership depends on what is registered on the title deed.
- ✗Overlooking that any late payment appears in both parties' credit records and affects their future borrowing.
- ✗Not agreeing in writing in advance on installment splits, ownership shares and what happens on separation or death.
International Differences
In the US and UK joint mortgages are common among spouses and partners, with a distinction between a co-borrower (debtor and usually owner) and a co-signer or guarantor (debtor without ownership). In the UAE banks allow a spouse's or relative's income to be added under conditions, and in Turkey and Egypt guarantors or co-borrowers are used per bank policy. In Saudi Arabia the Civil Transactions Law clearly governs solidarity and guarantee, while the conditions for combining income remain a matter of lender policy.
