Refinancing your home loan can unlock significant savings — but if you originally took out your mortgage with a co-borrower, the process becomes a little more nuanced. Whether your co-borrower is a spouse, a parent, or a sibling, their involvement in the refinance matters legally and financially. Many Filipino homeowners are unsure whether their co-borrower must participate in the new loan, what happens if the co-borrower wants to be removed, or how their co-borrower's credit and income will be reassessed by the new lender.
This guide answers the most common questions about co-borrower refinancing in the Philippines. Nook works with all major Philippine banks — including BDO, BPI, Metrobank, Security Bank, and more — to find you the best refinance rate, currently as low as 5.99% p.a. Our service is completely free to borrowers, and our team will guide both you and your co-borrower through every step of the process.
In most cases, yes — if your original home loan was taken out jointly with a co-borrower, Philippine banks will require that co-borrower to participate in the refinancing application as well. This is because refinancing creates an entirely new loan contract, not simply an amendment to the existing one. The new lender needs to assess and accept the full liability structure, including all parties who will be legally responsible for the debt.
That said, there are exceptions. If the primary borrower's income alone is sufficient to qualify for the new loan amount and the co-borrower formally agrees to be released, some banks may allow the refinance to proceed without the co-borrower — effectively removing them from the new contract. This process, however, requires explicit bank approval and supporting documentation. Speak to a Nook mortgage specialist to understand which banks offer the most flexibility in your specific situation.
Yes, refinancing is actually one of the cleanest opportunities to remove a co-borrower from a home loan in the Philippines. Because you are applying for a brand-new loan with a new lender (or even the same lender under new terms), you can simply exclude the co-borrower from the new application — provided you qualify for the loan on your own.
To successfully remove a co-borrower during refinancing, you generally need to demonstrate that your individual income meets the bank's debt-to-income requirements for the outstanding loan balance. Most Philippine banks require that your total monthly loan obligations not exceed 30–40% of your gross monthly income. For example, if your outstanding loan is 3,500,000 pesos and you are refinancing at 5.99% p.a. over 20 years, your estimated monthly payment would be around 25,000 pesos. Your gross monthly income would typically need to be at least 62,500–83,000 pesos to qualify solo.
Both parties should also sign a deed of release or similar legal document acknowledging the co-borrower's removal. A real estate attorney or your Nook advisor can guide you through the specific paperwork requirements.
Yes, refinancing also gives you the opportunity to bring in a new co-borrower who was not part of your original loan. This can be particularly useful if your financial situation has changed — for example, if you have recently married and want to include your spouse, or if you need a stronger income profile to qualify for a better rate or longer term.
Adding a co-borrower can improve your chances of approval and may help you qualify for a higher loan amount or a lower interest rate, since the bank now considers the combined income and credit profile of both applicants. The new co-borrower will need to submit a complete set of loan application documents, including proof of income, valid government IDs, and credit history. Both borrowers become equally and jointly liable for the new loan from the moment it is disbursed.
A co-borrower in a Philippine home loan refinance application is treated almost identically to the primary borrower from a documentation standpoint. Most banks will require the following from the co-borrower:
- Two valid government-issued IDs (e.g., passport, driver's license, SSS/GSIS ID, PhilSys ID)
- Proof of income: payslips for the last 3 months, Certificate of Employment (COE), and ITR for the last 2 years (for employed co-borrowers); or audited financial statements and DTI registration for self-employed co-borrowers
- Marriage certificate (if the co-borrower is the spouse)
- Proof of billing or residence
- Filled-out bank application form
If the co-borrower is an OFW, additional documents such as an employment contract, proof of remittance, and sometimes a Special Power of Attorney (SPA) may be required. Nook will provide a complete, bank-specific checklist for your co-borrower once you begin your application.
Yes, it can — and this is an important consideration that many borrowers overlook. When you apply for a refinance jointly with a co-borrower, Philippine banks will assess both applicants' creditworthiness. A co-borrower with a history of missed payments, unsettled loans, or a poor credit bureau record can negatively affect the overall application, potentially resulting in a higher interest rate, stricter loan conditions, or even outright rejection.
Conversely, a co-borrower with a strong credit history and stable income can strengthen a borderline application and improve the chances of securing a competitive rate like 5.99% p.a. If your co-borrower has credit issues, it may be worth exploring whether you qualify for the refinance on your own, or waiting until the co-borrower's credit profile improves.

Having an overseas-based co-borrower complicates the refinancing process but does not make it impossible. Philippine banks are accustomed to handling OFW loan applications and generally have provisions for remote participation. The most common solution is for the overseas co-borrower to execute a Special Power of Attorney (SPA), authorizing a trusted representative in the Philippines — often the primary borrower or another family member — to sign documents on their behalf.
The SPA must be notarized and, if executed abroad, authenticated by the Philippine Embassy or Consulate in the country where the co-borrower resides (or apostilled if that country is a signatory to the Apostille Convention). The overseas co-borrower will still need to provide all required income documents, which may include overseas employment contracts, proof of remittances, and foreign pay stubs. Processing times may be longer when a co-borrower is abroad, so it is advisable to start preparing these documents early in the refinancing process.
Generally, no — a co-borrower cannot unilaterally refinance a joint home loan without the primary borrower's knowledge and consent. Both parties are equal signatories to the original loan contract, and any refinancing creates a new legal obligation that requires agreement from all parties involved.
However, if circumstances have changed — for instance, due to separation, divorce, or the primary borrower's death — there are legal pathways to restructure the loan. In the case of a deceased primary borrower, the co-borrower may be able to assume full responsibility for the loan and refinance in their own name, subject to bank approval and settlement of estate matters. In separation or divorce cases, a court order or legal settlement may be necessary before a bank will allow one party to take over the loan independently. Nook recommends consulting a real estate lawyer alongside a mortgage advisor in these situations.
Once a new refinanced loan is signed, the co-borrower's liability is governed entirely by the terms of the new loan contract — not the original one. If the co-borrower is included in the new loan, they remain jointly and severally liable for the full outstanding balance. This means the bank can pursue either borrower for the full amount in the event of default, regardless of any private arrangement between the two parties.
If the co-borrower was removed during the refinance process and the primary borrower qualifies solo, the co-borrower is legally released from all obligations on the debt from the date the new loan is executed. It is critical to ensure that this release is formally documented — the old loan should be officially closed and the annotation on the Transfer Certificate of Title (TCT) or Condominium Certificate of Title (CCT) updated to reflect the new loan arrangement. Nook's team can help coordinate with banks and the Registry of Deeds to ensure all title annotations are correctly updated.
Yes — this is one of the key advantages of retaining a co-borrower in a refinance application. Philippine banks typically combine the gross monthly incomes of the primary borrower and co-borrower when calculating the maximum loanable amount and assessing debt-to-income ratios. This combined income approach can allow you to qualify for a larger loan, a longer repayment term, or access to better rate tiers that might not be available based on your income alone.
For example, if you earn 50,000 pesos per month and your co-borrower earns 40,000 pesos per month, most banks will consider a combined income of 90,000 pesos per month. At a 35% debt-to-income ceiling, this allows for monthly repayments of up to 31,500 pesos — which at 5.99% p.a. over 20 years could support a loan of roughly 4,400,000 pesos. If you are refinancing a Pag-IBIG loan and considering moving to a private bank, you can learn more about how combined income affects your options in our guide to Pag-IBIG home loan refinancing to private banks.
The overall refinancing timeline in the Philippines typically ranges from 4 to 10 weeks, depending on the bank and the completeness of your submitted documents. Adding a co-borrower does not significantly extend this timeline — provided both parties submit their required documents promptly and completely. Delays most commonly occur when the co-borrower is overseas and needs to authenticate an SPA, or when income documents from either party are incomplete or inconsistent.
Here is a general breakdown of the process: document preparation and submission takes about 1–2 weeks; bank credit evaluation and appraisal takes 2–4 weeks; loan approval and offer letter issuance takes 1–2 weeks; and loan release, title transfer, and annotation takes another 1–3 weeks. Nook's mortgage advisors manage the entire process on your behalf — following up with banks, flagging missing documents early, and keeping both the primary borrower and co-borrower informed at every stage. Starting your application through Nook is free and takes less than 10 minutes.
