Direct answer: In your 70s, it is worth discussing financial basics with adult children or trusted family members, at minimum sharing where key documents are located and who holds your durable power of attorney. Full financial disclosure is optional, but having a durable power of attorney in place is not.
Involving Family in Your Finances in Your 70s
Durable Power of Attorney: The Non-Negotiable
A durable power of attorney (DPOA) authorizes a person you name to manage financial decisions on your behalf. "Durable" means the document remains valid even if you later lose mental capacity, which is the whole point of having one in place now rather than waiting for a need. Without a DPOA, family members who want to help cannot legally act on your accounts or property without going to court to establish guardianship, a process that is expensive and time-consuming.
Execute a DPOA with an estate planning attorney before you have any need for it. Requirements vary by state. Once executed, keep the original in a safe place and give copies to your named agent and your attorney. Tell your financial institutions it exists; some require their own proprietary form in addition.
What to Share vs. What to Keep Private
The minimum worth sharing with a trusted family member or your DPOA agent: where your key documents are (will, trust documents, insurance policies, account statements, DPOA, healthcare directive), the name of your attorney and financial advisor, and how to access your document storage location. This does not require sharing balances.
Full financial disclosure (specific balances, holdings, and account numbers) is optional. Some people prefer to share everything to make administration easier; others prefer to share only what is necessary. Either approach is reasonable. What is not reasonable is sharing nothing: if something happens to you and no one knows where your documents are, those documents cannot help you.
Family Conversations About Estate Plans
You are not required to explain your estate plan to your heirs, but doing so reduces the chance of conflict after you are gone. Common points worth discussing: that you have a will and where it is, any trusts that exist and their general purpose, who the executor is, and any bequests that might be unexpected (a large gift to a charity, an unequal distribution among children). You do not need to disclose dollar amounts. The goal is to reduce surprise, not to get approval.
Family meetings about estate plans work best with clear framing: this is what I have decided, not a request for input on decisions already made. Inviting questions is generous; reopening settled decisions is not required.
Choosing a Financial Proxy
Your DPOA agent and your financial proxy may be the same person or different people. Key qualities: financial literacy sufficient to follow instructions, geographic accessibility for in-person tasks if needed, personal integrity, and the ability to act under pressure without becoming emotionally paralyzed. A child who manages their own finances well is a reasonable candidate. A trusted friend with no financial interest in your estate is another.
Avoid choosing someone based purely on birth order or family expectation. The task is administrative management during difficult circumstances, not an honor. Tell the person you are naming them before you sign the document, and confirm they are willing to serve. Name a backup agent in case your first choice is unable or unwilling to act when needed.
Cognitive Decline Planning
Cognitive decline, when it comes, typically progresses gradually. Planning while capacity is intact is far simpler than trying to establish structures after a diagnosis. Beyond the DPOA, the key steps: designate a trusted contact at each financial institution, consolidate accounts to reduce the number of institutions your agent must manage, set up automatic payments for recurring bills (mortgage, insurance, utilities), document the location of all financial records, and create a simple summary document listing every account, institution, and approximate balance for your agent.
Consider setting low-dollar transaction alerts on financial accounts so that unusual activity is visible. Discuss with your attorney whether a revocable living trust would be useful in your situation, as trust assets pass outside probate and can be managed continuously by a successor trustee if you become incapacitated.

Frequently Asked Questions
What is a durable power of attorney?
A durable power of attorney (DPOA) is a legal document authorizing a designated person (your agent) to manage financial decisions on your behalf. "Durable" means it remains in effect even if you lose mental capacity, unlike a standard power of attorney which terminates on incapacity. A DPOA can take effect immediately upon signing or only upon a defined trigger event (called a springing DPOA). Consult an estate planning attorney in your state; requirements and scope vary by jurisdiction.
Do I have to tell my children my account balances?
No. You are not required to disclose your account balances to family members at any age. The minimum useful disclosure is where your key documents are located (will, trust, account statements, insurance policies, DPOA) and who holds your durable power of attorney. Beyond that, how much to share is a personal decision. Full disclosure is one option; sharing only document locations with a named proxy is another.
How do I plan for cognitive decline?
Planning for cognitive decline involves several steps: execute a durable power of attorney before capacity is in question, designate a trusted contact at each financial institution, consolidate accounts to reduce the number of institutions involved, set up automatic payments for recurring bills, and document your wishes and the location of all financial records. Having these structures in place before any decline begins is far easier than trying to establish them after a diagnosis.
