A Practical Checklist for Managing Someone Else's Money

What to gather before you start managing finances

Before you take on financial caregiving, you need to know what you're actually managing. Start by collecting documents that show what accounts exist, what's owed, and what comes in each month. This isn't about being thorough for its own sake — it's about preventing bills from going unpaid or accounts from being frozen because nobody knew they existed.

The core documents are: bank and credit card statements (at least three months), mortgage or lease paperwork, insurance policies (health, auto, home, life), tax returns from the past two years, and any loan documents. If your loved one receives Social Security, pension payments, or other regular income, get the most recent statement showing the amount and deposit date. If they own property, get the deed. If they have a will or trust, get that too — it affects what you can and cannot do with their money.

Ask your loved one directly where they bank, what credit cards they hold, and whether they have any accounts you might not know about. Many people have old savings accounts, forgotten investment accounts, or insurance policies from decades ago. If your loved one is no longer able to communicate clearly, ask family members or look through mail and email for account statements.

Key Takeaways

• Gather three months of bank statements, insurance policies, loan documents, and proof of income before you begin, so you know what bills exist and when they're due.
• Determine what legal authority you actually have — power of attorney, guardianship, or joint account access each allow different actions and require different paperwork.
• Set up a system to track recurring bills by due date, so payments don't slip through because you forgot which month they're due.
• Create a list of account usernames and passwords in a secure location, and tell at least one other trusted person where that list is kept.
• Contact each financial institution to understand their rules for account access and what documents they need to recognize your authority.

Determine what legal authority you actually have

Your ability to manage someone else's money depends on what legal documents are in place. The three main routes are power of attorney, guardianship, and joint account access. Each one allows different things and requires different proof.

A power of attorney is a document your loved one signs (while they're still able to understand what they're signing) that names you to handle their finances. It's the least restrictive option and the fastest to set up. The person who signs it can revoke it at any time, and it ends when they die. If your loved one has already lost the ability to make decisions, a power of attorney is no longer possible — you'll need guardianship instead.

Guardianship is a court process that gives you legal authority over someone's finances and personal decisions when they can no longer make them. It takes longer (usually several weeks to months), costs money in court fees, and requires you to report to the court periodically. But it's the only option if your loved one cannot sign documents. Some states have a simpler version called conservatorship that covers finances only, without the personal decision-making authority.

Joint account access means your name is on the account alongside theirs. This works for checking and savings accounts but not for all financial matters. It's the fastest option if your loved one is still able to go to the bank with you, but it doesn't give you authority over loans, investments, or insurance policies.

Make a list of all recurring bills and their due dates

Bills don't stop coming because someone needs help managing money. Create a simple document — a spreadsheet or even a printed list — that shows every bill, the amount, the due date, and how it's paid (online, by check, automatic withdrawal). Include utilities, insurance, property taxes, loan payments, medical bills, and subscriptions. Many people forget about annual or quarterly bills until they're overdue.

Next to each bill, write down the account number and the phone number or website where it's paid. If the bill is paid automatically, write down which account it comes from and when the withdrawal happens. If you need to pay it manually, note whether you can pay online or whether you need to mail a check.

Set reminders on your phone or calendar for bills that are due on specific dates. If you're managing money for multiple people, color-code or label each person's bills so you don't accidentally pay the wrong person's electric bill from the wrong account. Review this list once a month to make sure nothing has been added or changed.

Create a secure system for passwords and account information

You need access to online accounts to pay bills and monitor balances, but passwords should not be written on sticky notes or stored in an email draft. Use a password manager — a secure digital vault where you can store login information. Common options include Bitwarden (free), 1Password, or LastPass. These encrypt your passwords and let you share access with a co-caregiver if needed.

If your loved one is still able to help, ask them to change their passwords to ones you both know, or to add you as an authorized user on accounts. If they're not able to help, you may need to use the "forgot password" feature to reset passwords, which usually requires access to their email or phone number.

Write down where the password manager is, what the master password is, and give that information to at least one other trusted person — a family member, attorney, or close friend. If something happens to you, that person needs to be able to step in. Do not keep this information in the same place as the password manager itself.

Contact banks and financial institutions about your authority

Each bank, credit card company, and insurance provider has its own rules about who can access an account and what documents they need to see. Call the customer service number on each statement and explain your situation. Ask what they need from you to recognize your authority — usually a copy of the power of attorney, guardianship papers, or proof that you're a joint account holder.

Some institutions will mail you forms to fill out. Others will ask you to come in person with the original documents. A few will require notarization. Do this before you need to make a payment or change something, so you're not scrambling when a bill is due.

Ask each institution whether they have a "caregiver alert" or similar flag you can place on the account. Some banks offer this service at no cost and will flag the account so that staff know to expect calls or visits from you. Also ask whether they can send statements to your address in addition to your loved one's, so you don't miss anything.

Set up a filing system for documents and receipts

You'll accumulate a lot of paper: bank statements, bills, receipts, insurance documents, and correspondence from financial institutions. Create a simple filing system — either physical folders or digital folders on your computer — organized by category: Banking, Insurance, Bills, Taxes, Legal Documents, and Medical. Within each category, organize by year or by institution.

Keep receipts for any money you spend on your loved one's behalf, especially if you're using your own money temporarily. These receipts matter if there's ever a question about what happened to their money, and they're essential if you're a guardian and need to report to the court.

Store original legal documents (power of attorney, will, trust, guardianship papers) in a safe place — a safe deposit box, a home safe, or with your attorney. Keep copies in your filing system. Do not rely on digital copies alone for documents that institutions might need to see in original form.

Plan for what happens if you can't manage the finances anymore

Caregiving circumstances change. You might become ill, move away, or simply reach a point where you can't manage alone. Before that happens, identify a backup person — another family member, a professional fiduciary, or a trust company — who can take over if needed.

Tell that person where your filing system is, where the password manager is kept, and what authority you currently have. If your loved one is still able to make decisions, ask them to sign a power of attorney naming this backup person as successor. If they're not able to sign, talk to an attorney about whether guardianship succession is possible in your state.

Some people hire a professional fiduciary or conservator to manage finances from the start, especially if the financial situation is complex or if family relationships are strained. This costs money, but it removes the burden from family members and provides a neutral third party. Ask your local Area Agency on Aging or an elder law attorney for referrals.

Frequently Asked Questions

Do I need a lawyer to set up power of attorney?

Not always. Many states allow you to use a template form, which costs nothing. However, if your loved one's finances are complex, if there's family conflict, or if you're unsure whether they can still make decisions, an attorney can make sure the document is done correctly. An elder law attorney typically charges $300 to $1,000 for a power of attorney.

What if I find an account or debt I didn't know about?

Contact the institution immediately and ask for a statement showing the balance and payment history. If it's a debt, ask whether it's current or past due. If it's an account with money in it, make sure it's included in your bill-paying system. Don't ignore unknown accounts — they can affect credit scores and may have ongoing fees.

Can I use my loved one's money to pay myself for caregiving?

This depends on your legal authority and your state's rules. If you have power of attorney, you may be able to pay yourself a reasonable amount for services, but you should document this carefully. If you're a guardian, you usually need court permission. Talk to an elder law attorney about what's allowed in your situation.

How often should I review accounts and bills?

Check bank accounts and credit cards at least monthly to catch fraud or errors. Review the full bill list quarterly to make sure nothing has changed. If your loved one's situation is complex or unstable, check more often. Set a calendar reminder so you don't forget.

What should I do if I spot fraud or unauthorized charges?

Contact the financial institution immediately by phone — don't wait for mail. Report the specific transaction, ask them to freeze the account if needed, and request a new card or account number. Ask whether they can reverse the fraudulent charge. Document the date and time of your call and the name of the person you spoke with.
