Legal Responsibilities and Hidden Links
When applying for a credit card, even if only one spouse applies, some banks include “spousal consent” in the contract. This can open the door to the spouse's assets being included in the legal proceedings if the debts are not paid. Many families in the US who are unaware of the difference between a “joint account” and an “authorized user” find out too late that only one person is legally responsible for the debt when using the card together.
An authorized user added to a credit card can make purchases but is not responsible for making payments. However, some banks reflect the authorized user's information in their credit history, so poor credit usage can damage the entire family's credit score. In some states, a spouse's credit card debt can result in wage garnishment, especially in areas where community property laws apply.
In married couples with joint credit cards, if the card limit has not been exhausted at the time of divorce, the debt may be split equally between both parties unless there is a clear agreement on who will pay it. In some divorce cases, credit card debts can turn into disputes lasting as long as child support.
Psychological and Social Dynamics
Research shows that sharing credit cards between couples leads to more financial disputes in marriage. This is mostly due to “uninformed spending” and “hidden debt.” In couples who use joint credit cards, one partner not disclosing their spending to the other is a common issue in divorce cases. Some divorce lawyers in the US refer to this as “financial infidelity.”
When young adults share credit cards with their parents, it can lead to parents trying to control their children's behavior. This can increase conflict when the cardholder interferes with spending.
Credit Score Impact and Surprise Risks
An individual added as an authorized user may lose their own credit score if the card is not paid on time. This can be particularly devastating for young adults who are in the process of building their credit history. Some families add their children as authorized users to help them build their credit history. However, a mistake in debt repayment can completely reverse this strategy.
Some banks do not include authorized users in credit reports, while others report the entire account history. These differences can lead to unexpected credit score changes among family members. In rare cases, when the credit card holder passes away, the spouse or children who are authorized users may be left responsible for the debt associated with the card. Although they are not legally liable, banks may pressure them to pay off the debt.
Tax and Corporate Implications
In the UK, some tax audits may have difficulty distinguishing between personal and family expenses on jointly held credit card accounts. This can be particularly challenging for self-employed individuals who use the same card as family members to document business expenses. In Canada, some accountants recommend using transaction tagging software to organize “mixed expenses” for couples who share credit cards.
Some banks can generate reports that indirectly share authorized users' card usage history with the cardholder's employer or insurance provider. This can have indirect effects on careers and insurance premiums in certain industries.
Fraud, Identity Theft, and Authorization Issues
Fraud or unauthorized spending by family members who are authorized users of a joint card falls under the legal category of “internal fraud.” Banks often consider these cases to be “family matters” and do not issue refunds. In some cases, an authorized user may make large purchases without the cardholder's knowledge and then disappear. In such cases, the bank holds only the primary cardholder responsible, as the debt is legally registered in their name.
Some identity theft protection services (e.g., fraud monitoring services offered by banks) may limit the functionality of authorized users. For example, if someone using a child's name is added to the system and their age cannot be verified, the transaction may be declined. In some US states, an authorized user may be held passively liable for the debt in the future, even if they did not make any purchases, due to the “acknowledgment of debt and waiver of objection” clause. This is particularly common in cases of long-term joint use.
Transfer of Cards to Heirs and Death
When the cardholder dies, the authorized user's access to the card is usually revoked immediately. However, some banks do not automatically revoke access, so family members may continue to use the card without realizing it. In this case, all charges become illegal and may result in legal action.
In some states, the deceased person's credit card debts are covered by the “estate,” or remaining assets. However, the authorized user is not directly liable for these debts. Nevertheless, family disputes may arise during this process if it is unclear who incurred the debts. In the US, some financial advisors recommend that spouses be “joint account holders” rather than authorized users. This is because automatic card access termination in the event of death can cause hardship for the surviving spouse.
Significant Differences Between Bank Policies
Chase Bank reflects individuals added as authorized users on credit reports, while Capital One does not report this information in some cases. This difference can lead to completely different results for families using the same strategy. Some American Express card programs allow individual limits to be set to restrict the spending of authorized users. This feature is a rare but valuable option for those who want to control the spending limits of family members.
Barclays requires that the cardholder has been actively using the card for at least six months before an authorized user can contribute to their credit history. Such details can create critical differences in plans for building credit history for children. Some premium cards (such as Amex Platinum) charge an annual fee for adding authorized users. This is an often-overlooked factor that can increase the cost of shared usage decisions.
Real-Life Examples
In the US, a father made his son an authorized user to help him with college expenses. However, the son racked up $9,000 in debt by constantly treating his friends to meals and making online purchases. When the debt went unpaid, the father lost his credit score and was denied a mortgage.
A couple continued to use their credit card limit together after their honeymoon. However, after the woman moved out, the man had to pay off the entire debt because it was legally in his name. The woman made no payments, and the bank could not legally intervene.
Common Mistakes and Misconceptions About Joint Use
Many families believe that adding an authorized user is merely a practical “granting of permission”; however, this step actually directly includes that person in the credit history. Therefore, preparing a written spending protocol before adding an authorized user can prevent future crises within the family. If expenses are not tracked during joint credit card use, disputes over who incurred the debt may arise afterward. Especially in a shared living arrangement with a single account, banks do not hold both parties responsible for such claims because they cannot be substantiated, and only pursue the primary debtor.
Some families want to educate their children financially by making them authorized users at an early age. However, if no explanation is given about the card limit, spending categories, and payment dates during this process, the child will only get the impression that they have “unlimited money.” This situation has negative consequences both in terms of habits and character development. Some parents add cards to help their children build credit history, but the child may later use this history in harmful ways without realizing it. For example, in a new card application, the authorized user history may be misinterpreted as high-risk credit behavior.
Shortcomings of Technological Systems and Digital Tracking Tools
In many banking apps, the spending of authorized users cannot be viewed separately from the spending of the cardholder. This makes financial transparency within the family difficult. While some fintech apps address this shortcoming, most users do not use these tools. Since the statement of a shared card does not clearly indicate which individual purchased what, detailing monthly expenses can become a time-consuming manual process. This is both time-consuming and relationship-wearing.
Although some banks offer the option of setting spending limits for authorized users, there have been cases where these limits have been exceeded or the system has failed to record such instances. Such system loopholes can put family members who want to stay within their limits in a difficult position. A feature recommended by financial advisors but rarely implemented by users is the categorization of card expenditures. This feature helps identify which expenditures were made by whom; however, very few families regularly track this information when using a shared card.
The Role of Authorized Users with Unlimited Permissions That Is Invisible to Banks
An authorized user can use the card in their own name, so they may appear as the only person registered in the system for online purchases, for example. This can lead to legal liability confusion in cases of fraudulent transactions. Some authorized users may contact the bank's customer service without the cardholder's knowledge and perform certain transactions. For example, some banks may process transactions such as new card requests, address changes, or account statements without verifying the identity of the authorized user. This creates a serious security vulnerability.
An authorized user may sometimes act as the “sole owner of the account” after the cardholder's death. Especially if transactions made with the card are still active in the bank's records, this can lead to legal disputes over inheritance rights.
Card Cancellation, Account Freezing, and the Uncertain Status of Authorized Users
When a cardholder cancels their credit card, many people assume that the authorized user is also automatically deleted from the system. However, in some banks, this process is manual, and the authorized user data may remain “inactive” in the system. This opens the door to data breaches and misuse. Canceling the card without deleting the authorized user can cause the person to still appear active in their credit history. This can lead to negative impressions of the individual when they apply for credit in the future due to their old account.
Some banks allow account holders to freeze their accounts if they notice irregularities; however, this does not prevent authorized users from using the card. For a real transaction block, all users' access must be specifically restricted. After the card is canceled, some authorized users may notice the situation late, and automatic payments may continue because the card details are still registered on online platforms. Such payments may result in new debts without the cardholder's knowledge.
International Legal Differences and Interesting Practices
In Canada, in some provinces, even if an authorized user does not enter into a legal debt relationship due to transactions made with the credit card, the bank may share this information with insurance companies. This can affect the individual's insurance premiums. In the US, the information of children added as authorized users may be recorded as “dependent risk” on their parents' credit reports in some cases. In other words, the risk score associated with the child may affect the parent's financial rating.
In the UK, some banks define authorized users as “additional cardholders,” while others technically classify them as “limited joint holders.” This technical difference can have significant consequences in legal proceedings regarding debt sharing and liability. In Australia, the age limit for authorized users of joint credit cards is 16, while some banks do not issue cards to users under the age of 18. However, if the cardholder allows these individuals to make purchases on their behalf, they are considered to be in violation of the card rules.
Uncertainty of Responsibility for Payments and Creditors' Attitudes
When issues arise regarding debt repayment, creditors typically only pursue the cardholder. However, in some cases, if the authorized user's information is fully recorded with the bank, debt collection agencies may contact these individuals to exert psychological pressure. While the communication between debt collection agencies and authorized users is often not legally binding, it aims to create a sense of responsibility, encouraging voluntary repayment of the debt. This situation can become a serious source of stress for young users or elderly family members.
When the authorized user makes high-value purchases that exceed the cardholder's budget, debt restructuring becomes necessary. However, the authorized user is not involved in this process in any way; the responsibility lies entirely with the cardholder.
Financial Education and Authorized User Strategies
Some financial coaches advocate the authorized user strategy to help family members develop a credit culture. However, for this method to work, the cardholder must have strong spending discipline; otherwise, the authorized user may inherit a negative credit legacy. Credit score improvement for children added as authorized users for educational purposes is only possible if the bank shares the relevant information with credit bureaus. Since not all banks share this information, the investment may sometimes be ineffective.
Some families choose to share physical credit cards rather than limited virtual cards to monitor their children's financial behavior. However, in this approach, the child's spending affects their credit score not only in the short term but also in the long term.
Authorized User Removal Processes and Important Details Cardholders Should Know
Some banks process authorized user removal requests immediately, while others only process this change at the end of the billing cycle. Any spending made during this delay period is still charged to the cardholder and may lead to disputes. A significant number of banks only accept authorized user removal requests via phone customer service. However, in some cases, the cardholder must provide additional written consent for this process to be completed. These procedural differences can cause delays for the cardholder.
The name of the deleted authorized user may leave a permanent mark on the credit report. If the bank does not update the relevant data, the authorized user may be negatively affected by the poor credit history of this account in the coming years. In some banks, even if the authorized user is deleted, past usage information may continue to appear on the credit report for years. This situation may cause the authorized user to encounter a low credit score when applying for another card in the future.
Psychological and Legal Consequences of Divorce and Joint Cards
The division of credit card debt after divorce can cause more disputes than the division of household goods. This is because the lack of digital evidence regarding who incurred the debt leaves the process to personal claims and emotional distress. Many couples cannot agree on who will pay their credit card debt during divorce proceedings. In such cases, courts examine whether the authorized user has “indirect contribution” even if they have no legal obligation. They question whether the expenses were made for the children or for personal enjoyment.
If the authorized user remains in the system after the divorce and the cardholder forgets to remove them, there is a possibility that the former spouse may use the card. These expenses may be legally actionable, but the cardholder's delay complicates the process. Some divorced couples continue to pay for high-value items purchased together using a joint card. However, when payments cannot be made, only the cardholder faces the financial consequences. This situation can also create a psychologically tense environment.
Domestic Violence, Financial Control, and Credit Card Addiction
Shared credit card use can be abused by individuals who exercise financial control. In particular, the cardholder spouse excluding the other person from spending or using the card as a means of pressure is considered an example of modern financial violence. In cases of financial abuse, the authorized user may gradually feel worthless or dependent. Steps such as card cancellation, limit restrictions, or monitoring spending history can undermine an individual's self-confidence and economic freedom.
In some cases, the authorized user sees the card as a “bonding tool.” Especially in emotionally manipulative relationships, joint card use fosters a sense of attachment or indebtedness and makes it difficult for the individual to leave the relationship.
Alternative Methods to Joint Use and New Generation Applications
Instead of traditional joint cards, using virtual spending cards or prepaid cards with predefined limits provides spending control and reduces legal liability risks. Some fintech applications offer spending tracking panels for children and spouses. With these tools, card spending can be tracked in real time, and transparency can be ensured through notifications. However, most of these applications are only integrated with specific banks.
A rising trend, “credit score-building focused authorization apps,” allow individuals to benefit from their credit history but do not allow them to physically use the card. This keeps risk to a minimum. Instead of joint credit card use, applying for low-limit personal cards for family members provides financial freedom and a healthier start in terms of credit history.
