Can't go to the bank in person but still need to conduct transactions? A bank transaction authorization form is a simple and legal solution that allows you to have someone else handle procedures such as withdrawing money, transferring funds, or dealing with the bank on your behalf. In this article, you will understand what a bank authorization form is , when to use it, how to write it correctly , and important notes to avoid potential risks. The content is presented concisely, easy to apply, and suitable even for those who are creating an authorization form for the first time.

Method 1: Obtain a legally valid bank authorization document.

Step 1: Authorize financial transactions through banking.

Consider obtaining a financial power of attorney for limited transactions. In fact, most banks do not allow someone else to transact on your behalf if they are not the account holder, unless there is a legally valid power of attorney . This is usually done by signing a Financial Power of Attorney (FPOA) , which specifies the scope of transactions permitted .

  • The power of attorney document must specify who the authorized person is.

  • Clearly define the types of banking transactions that are permitted.

  • It has the signature of the authorized person and meets the bank's authentication requirements.

Understanding Limited Financial Authorizations (Limited FPOAs) correctly. This is a common form of authorization when you only need someone to assist with a few specific transactions for a short period of time.

  • Only the listed transactions are allowed (e.g., withdrawals, deposits, check signing).

  • No full control over the bank account.

  • Suitable for when you are busy with work, traveling, or unable to go to the bank in person.

Consider a durable financial authorization plan (Durable FPOA) when necessary. If you want an authorized person to manage your finances long-term , even if you lose the ability to make decisions independently, this is a suitable option.

  • An authorized representative can make financial decisions on your behalf.

  • The power of attorney remains valid even if you are no longer able to conduct transactions.

  • Often used in long-term financial planning or healthcare.

Practical considerations when preparing a power of attorney for bank transactions.

  • Always check the bank transaction authorization form provided by each bank.

  • The clearer the scope of authorization, the lower the risk.

  • Only authorize individuals who are trustworthy and fully understand their legal responsibilities.

Step 2: Contact the bank to obtain the appropriate power of attorney form.

Proactively contact your bank to request a sample bank transaction authorization form. In fact, most major banks have their own authorization form (also known as a third-party authorization form) and require customers to use the correct form for transactions to be accepted.

  • Bank authorization forms are usually issued by the bank.

  • Not all standard templates are applicable to all banks.

  • Using the correct form helps expedite the processing of your application and avoids rejection.

Provide all the required information in the power of attorney form. When filling out the power of attorney for bank transactions, you need to clearly state the scope and duration of the authorization so that the bank can manage the risks.

  • Authorized person's information (full name, identification document)

  • Banking transactions are permitted.

  • Duration of authorization (short-term or long-term)

Choose the appropriate method for obtaining a power of attorney form. Depending on your personal circumstances, you can access power of attorney forms in two common ways.

  • Go directly to a bank branch to receive assistance from a staff member.

  • Visit the bank's official website to download the online authorization form.

Complete and submit the application according to the bank's instructions. After filling out the bank transaction authorization form, carefully check the information before submitting it.

  • Sign your full name as required.

  • Notarization or authentication if required by the bank.

  • Submit your application in person or as instructed.

Step 3: Prepare your own financial authorization form if the bank doesn't provide a template.

Create your own financial authorization document if the bank doesn't provide a template. If the bank doesn't have a specific bank transaction authorization form , you can absolutely draft your own authorization document, as long as the content clearly and specifically states the scope of permitted transactions .

  • Accurately record all transactions performed by the authorized person (withdrawals, transfers, document signing, etc.).

  • Clearly state the authorization period to avoid unforeseen risks.

  • The personal information of both parties must match their identification documents.

Ensure the content complies with current legal regulations. For the power of attorney to be legally valid, the document must be drafted in the correct legal language and in accordance with the laws of your place of residence.

  • Use clear language and avoid ambiguity.

  • Do not expand rights beyond actual needs.

  • In compliance with regulations on financial authorization and banking transactions.

The power of attorney must be signed in accordance with legal procedures. The signing of a financial power of attorney must be done correctly for the bank to accept it.

  • The person granting the authorization signs directly in the presence of the person receiving the authorization.

  • Follow the requirements for witnesses or notaries, if any.

  • The date of signing should be clearly stated in the document.

Consider seeking legal assistance when necessary. For complex financial authorization cases or large transaction values, legal review can help mitigate legal risks.

  • Ensure the power of attorney is valid and well-documented.

  • Avoid disputes or rejection by the bank.

  • Suitable for long-term authorization or full authorization.

Step 4: Submit the power of attorney at the bank to officially take effect.

Bring the bank transaction authorization form to the bank in person. After completing the information and signing in accordance with legal regulations, you need to go to the bank to register and file the authorization document .

  • Prepare the original signed power of attorney.

  • Bring the authorized person's identification documents.

  • Check the specific requirements of each bank beforehand.

Work directly with the bank staff to confirm your authorization intentions. Clear communication helps the bank understand the scope and duration of the authorization you desire.

  • Confirm who the authorized person is.

  • Clarify which banking transactions are permitted.

  • Check the validity period of the power of attorney.

Complete the authorization process by saving the authorization document in the bank's system. Once the authorization is accepted and stored by the bank, the right to conduct transactions will officially arise.

  • The authorized person can execute the transactions as stated.

  • The bank only processes transactions within the scope of its authorization.

  • All transactions are monitored according to registered records.

Keep these points in mind to avoid potential problems.

  • It is advisable to keep a copy of the power of attorney for reference when needed.

  • Notify the bank immediately if you wish to change or cancel the authorization.

  • Do not delegate beyond actual needs to reduce risk.

Option 2: Add a co-owner or open a bank utility account.

Step 1: Consider opening a convenient authorized account at the bank.

Consider opening a utility account if you don't want full authorization. This type of account allows others to use your account on your behalf, but only to serve your needs , not their personal purposes. This is often used when you need help managing daily expenses but still want to maintain close control over your cash flow.

  • Those granted permission can pay bills and living expenses.

  • Cash withdrawals for personal use are prohibited.

  • All transactions are understood to be performed on behalf of the account holder.

Check the legal regulations before choosing this option. Not all localities or banks allow opening authorized utility accounts, so researching beforehand is very important.

  • Consider whether current legal regulations permit this type of account.

  • The default settings do not apply equally to all cases.

  • Some banks have different names or implementation conditions.

Proactively contact the bank to assess its suitability. Before making a decision, you should discuss directly with the bank to ensure this type of account meets your actual needs.

  • Clarify the scope of authority of the authorized person.

  • Compared to the conventional bank transaction authorization form.

  • Assessing the level of financial safety and risk control.

Step 2: Consider adding a co-account holder for the bank.

Consider adding another person as a co-account holder when full access is needed. Most banks allow you to add one person as a co-account holder , thus creating a joint account . This person then has equal transaction rights with you, without the limitations of a bank transaction authorization.

  • You can withdraw money, transfer funds, make payments, and manage your account.

  • The same privileges as the original account holder.

  • Suitable for spouses, relatives, or trusted partners.

Follow the bank's procedure for adding a co-account holder. To add a co-owner, the bank requires both parties to participate in the procedure.

  • Fill out the form provided by the bank completely.

  • Both parties sign the confirmation as required.

  • Present valid identification.

Complete the necessary paperwork to make the joint account valid. Once the bank receives and processes the application, access will be activated immediately.

  • The added user has full access to the account.

  • The bank does not differentiate between primary and secondary roles among co-owners.

  • All transactions have equal legal validity.

Important note before adding co-owners to an account.

  • Unlike a power of attorney, the scope of transactions is not limited.

  • Suitable for general financial management, not suitable for temporary support needs.

  • The level of trust needs to be carefully considered to avoid financial risks.

Step 3: Be cautious when giving others full access to your bank account.

Carefully consider the risks of granting others full access. Opening a utility account or adding co-account holders carries inherent risks if not carefully considered. In particular, adding a co-account holder gives that person full access to the account without any transaction limitations.

  • Joint account holders can withdraw, transfer, and spend money as they wish.

  • The original account holder did not have control over each transaction.

  • The risk increases if conflicts arise or the funds are misused.

Even utility accounts require a high level of trust. Although the scope of authority is more limited, the authorized person still directly manipulates your money.

  • We need to have complete trust in the transparency and accountability of the authorized person.

  • Suitable for situations where you only need assistance paying the costs on your behalf.

  • Do not apply if you have doubts about how to manage your money.

It's advisable to consult with a lawyer before deciding on the appropriate form. Based on practical experience, many legal experts recommend a durable financial authorization document (FPOA) instead of a joint account in many cases.

  • Maintain better control over your finances.

  • Clearly define the scope and purpose of authorization.

  • Easily adjustable or terminated when needed.

Be especially cautious when adding children to a bank account. Many people choose this method to have their children help pay bills, but in the long run, unforeseen problems can arise.

  • Legal troubles or property disputes are likely to occur.

  • Poor management can negatively impact personal financial planning.

  • It is necessary to establish financial protection measures from the outset.

Method 3: Authorize another person to deposit or withdraw money from the account.

Step 1: Allow others to deposit money into your bank account.

Clearly define your needs as solely for depositing funds, not for other transactions. If your purpose is simply to allow others to deposit money into your bank account , many banks allow this without requiring a bank transaction authorization form or complicated legal procedures.

  • The authorized person is only permitted to perform the deposit operation.

  • No permission to withdraw money, transfer funds, or sign documents.

  • Suitable for receiving money on behalf of relatives, partners, or customers.

Check each bank's third-party deposit policy. Regulations regarding depositing money into other people's accounts are not exactly the same between banks .

  • Some banks allow deposits at the counter or ATM.

  • Some banks have limits on the amount of money or require basic documentation.

  • A letter of authorization or a form is not always necessary.

Proactively contact the bank to avoid any problems. To ensure the transaction is approved, you should ask for clarification before proceeding.

  • Inquire about third-party payment regulations.

  • Confirm if any documents or information are required.

  • Avoid situations where customers are refused payment at the counter.

Step 2: Allow others to withdraw money from your bank account.

You should never give your bank card or account information to others without their consent. While giving your ATM card, PIN, or account information might allow someone else to withdraw money on your behalf, banks advise against this practice due to the significant risks involved.

  • You have no control over the amount of money withdrawn.

  • Disputes can easily arise if mistakes occur.

  • Banks are generally not responsible when you provide information yourself.

Many banks do not allow withdrawals by individuals whose names are not on the account. In fact, some banks have policies prohibiting transactions to third parties , even if they have the card or account information.

  • Transactions may be rejected at the counter or ATM.

  • Your account is at risk of being locked for security checks.

  • Difficult to handle when problems arise.

Prioritize legal and risk-controlled solutions. If you need someone else to withdraw money on your behalf, choose methods recognized by the bank.

  • Create a Public Fund Authorization Form (FPOA) to clearly define the scope of withdrawals.

  • Add that person as a co-signer or co-account holder if full access is needed.

  • Work directly with the bank to choose the right option.

Practical tips for protecting your account.

  • Only authorize withdrawals when absolutely necessary.

  • Clearly state the authorization limit and duration.

  • Do not share your PIN or personal security information.

Có lần mình định thêm vợ vào làm đồng chủ tài khoản để ‘chia sẻ trách nhiệm’. Ai dè từ ngày đó, mỗi lần mình mua gì hơi đắt là y như rằng có tin nhắn hỏi: ‘Chi tiêu gì đây?’ Thế mới thấy, đồng sở hữu tài khoản không chỉ là chia sẻ quyền lợi mà còn chia sẻ cả… sự giám sát!

Mình từng đưa thẻ ATM cho bạn thân rút hộ, nghĩ đơn giản lắm. Kết quả là bạn ấy rút xong còn mua thêm ly trà sữa bằng tiền của mình. Từ đó mới hiểu tại sao ngân hàng khuyến cáo không nên đưa thẻ cho ai. Giờ thì ngoan ngoãn làm giấy ủy quyền, vừa hợp pháp vừa tránh mất thêm tiền cho trà sữa ngoài kế hoạch.

Lần đầu làm giấy ủy quyền ngân hàng, mình hí hửng nghĩ chắc chỉ cần ký cái roẹt là xong. Ai ngờ nhân viên ngân hàng nhìn mình như đang viết đơn xin việc. Cuối cùng mất cả buổi chỉ để điền đúng tên và số CMND. Đúng là ‘ủy quyền’ nhưng vẫn phải ‘tự thân vận động’ khá nhiều!

Expert Q&A

In-depth analysis and practical advice from leading experts.

Typically, a bank transaction authorization form needs to be signed in person and certified according to the requirements of each bank. Some banks require notarization to ensure legal validity, while many cases only require the valid signatures of the authorizing party and the authorized party. Therefore, you should contact the bank directly to find out the regulations and avoid being refused when conducting transactions.

Most major banks in Vietnam provide bank transaction authorization forms on their official websites or at their branches. You can download the form online, fill in the information, and then submit it directly to the branch. Using the correct form provided by the bank helps expedite the processing of your application and reduces the risk of rejection.

The validity period of a bank transaction authorization depends on the details you specify in the document. It can be short-term (for example, a few days or weeks for withdrawals or transfers) or long-term if you want someone else to manage your finances for an extended period. To ensure security, you should clearly state the validity period and scope of transactions in the authorization document so that the bank can easily monitor and avoid potential risks.
