Why register a power of attorney?

When you register your power of attorney with us, you can start acting on behalf of the Nationwide account holder. 

 As long as you’re acting in line with the power of attorney document, you can: 

  • Access someone’s accounts

    You can do what the account holder would. This includes checking statements, making payments and setting up payments. 

  • Speak to us directly

    If you have a question or request, we won't need to speak to the account holder. So, you can make decisions quickly and easily.

  • Manage someone’s finances

    To help you manage an account, you can personalise where we send statements, who has a card and online access.

What is a power of attorney?

A power of attorney is a legal document. It lets someone (the 'donor') choose one or more people ('attorneys') to make decisions on their behalf.

Why create a power of attorney?

A donor can create a power of attorney document to get help managing their money. They appoint one or more people ('attorneys') to act on their behalf when needed.

The donor can only create a power of attorney while they have the mental capacity to make decisions.

By appointing an attorney, the donor:

  • gives legal permission for the attorney to act on their behalf
  • keeps legal ownership of any money the attorney manages
  • can make their wishes clear (as the attorney has to act in their best interests).

There are different types of power of attorney, depending on:

  • the type of support you need, and
  • where you live in the UK.

To learn more about the types of power of attorney, visit Age UK (opens in a new window).

To create a power of attorney

The donor needs to have the mental capacity to decide:

  • What type of power of attorney they’ll need.
  • Who their attorney should be and how many attorneys they’ll need.
  • What their attorneys will have permission to do.

To learn more about mental capacity and power of attorney, visit GOV.UK (opens in a new window).

Other types of support

If someone cannot make decisions, first check if they have a lasting power of attorney (opens in a new window).

If not, you may need a Court of Protection Order.

For simple access to someone's account, we also offer Third Party Mandates.

What we can give attorneys

When you register as an attorney with Nationwide, you can request:

  • A chequebook

    We can give you and the account holder, or just one of you, chequebooks.

  • A card

    We can give you a card, but only if we cancel the account holder’s card.

  • Account statements

    Current accounts: both you and the account holder can choose to receive statements.
    Savings accounts: only one person can receive statements.

  • Online access 

    We may be able to give you and the account holder, or just one of you, access to the Internet Bank. You will need:

    • An account with us that’s eligible for Internet Bank access. If you don't already have Internet Bank access set up on your own accounts, we can set this up for you as part of the registration process.
    • A power of attorney document that doesn't include restrictions on what you can do. For example, limits to which accounts or how much money you can access.
    • A UK address when you register the power of attorney document.
    • To be personally named as an attorney in the power of attorney document.
    • To not be acting 'jointly' with another attorney. This means you have to make decisions together.
    • To not be acting on behalf of someone with a Nationwide joint account. If this is the case, you need to manage all of their accounts in branch.


If you lack mental capacity when your attorney registers with us, we can cancel your card and chequebook if requested. We can also send statements to the attorney. We cannot cancel your access to the Internet Bank or Banking app (if you were registered previously).

What attorneys cannot do

When acting as an attorney with Nationwide, you cannot:

  • Use or apply for credit

    We cannot let attorneys run up unsecured debt in someone else’s name. This means you cannot apply for credit cards, overdrafts or loans. But you can pay off existing debt and manage mortgage payments. 

  • Access all types of accounts

    We cannot register attorneys on the following savings accounts: Treasurer’s Trust, PortfolioInvestor, Business Investor or Child Trust Fund. 

  • Use telephone banking for payments or transfers

    You can call us to ask questions about the account, but attorneys cannot transact on the phone.

  • Use the Nationwide Banking app

    Attorneys cannot use our Banking app yet, but you may be able to use our Internet Bank.

  • Have a card if:

    • Your power of attorney document has restrictions on what you can do with that account. For example, there’s a limit to how much money you can access.
    • You’re acting ‘Jointly’ with another attorney. This means you have to make decisions together.
