Loan Guarantor Responsibilities: What to Check Before Signing

A loan guarantee can make you responsible under the agreement if the borrower does not pay as required. Do not sign simply because the borrower is someone close to you. The Bank of Thailand recommends considering the effects on your money, relationships, and family before helping someone borrow, and understanding financial-service terms before signing.

Checklist Before You Sign

1. Get complete copies of both the loan agreement and the guarantee agreement before signing.
2. Check the maximum guaranteed amount, duration, type of debt, and costs that may be added to the debt.
3. Ask how and through which channels the lender will notify you of a missed payment or a change to the terms.
4. Consider how paying on the borrower’s behalf could affect essential expenses, savings, and your own goals.
5. Do not sign blank documents or agree to contract changes you have not read.
6. Keep the documents and a record of any explanations from the lender.

If you do not understand the contract, ask the lender for a written explanation and seek independent professional advice before signing. Do not assume that being a relative or spouse removes liability. Rights and obligations depend on the agreement and applicable law, so do not determine them from a general article or social post.

See the debt service ratio guide for assessing repayment obligations, and the guide to notifying an estate about a debt for preparing a list of liabilities for family members.
