Why You Still Need a Power of Attorney Even If You Have a Joint Bank Account

Many couples and family members share a joint bank account for convenience. It is common to assume that if you already have a joint account with your spouse, partner, or parent, you will automatically be able to manage the finances if something happens to them.

However, this is one of the most widespread misunderstandings in estate planning.

A joint bank account does not replace the need for a Lasting Power of Attorney (LPA) and relying on one could lead to unexpected financial difficulties at a time when you need support the most.

Do You Need a Power of Attorney If You Have a Joint Bank Account?

Yes. Even if you share a joint account, you should still have a Property and Financial Affairs Lasting Power of Attorney in place.

A joint account may allow the other account holder to continue using the account day-to-day, but it does not give full legal authority to manage all financial matters, and in some situations, it may not even guarantee access to the funds.

A properly registered LPA provides clear legal permission for someone you trust to act on your behalf if you lose capacity.

What Happens If One Joint Account Holder Loses Mental Capacity?

If one account holder becomes unable to manage their finances due to dementia, illness or an accident, banks may need to take steps to protect that individual.

Even though the account is joint, the bank may:

• Freeze the account temporarily.
• Restrict withdrawals or transfers.
• Require proof of authority.
• Insist on seeing a registered Power of Attorney

Banks have safeguarding duties, and without an LPA, family members can face frustrating delays when trying to pay essential bills or care fees.

The UK Government’s guidance confirms that banks will generally only allow an attorney to act once an LPA has been registered with the Office of the Public Guardian.

Can a Joint Bank Account Be Used Instead of a Power of Attorney?

No, and it is not recommended.

While joint accounts provide shared access, they do not provide the wider authority needed to manage finances properly.

A Lasting Power of Attorney can cover:

• Other bank accounts held in sole name.
• Savings and investments
• Property transactions
• Pension payments
• Utility bills and care home fees
• Tax affairs and benefits.

In contrast, a joint account only relates to that single shared account and may still be restricted if capacity is lost.

What Are the Risks of Relying on a Joint Account Alone?

Relying only on joint accounts can create serious legal and financial risks, including:

1. Accounts Being Frozen or Restricted

Banks may intervene to prevent potential misuse or financial abuse, even if the account holder is a spouse.

2. Disputes Over Ownership of Funds

Questions about who owns the money can arise after death or loss of capacity, especially if large sums are held in the account.

3. Problems with Inheritance Tax and Estate Claims

Joint accounts can complicate estate administration, and surviving account holders may face challenges from other beneficiaries.

4. No Authority Beyond That Account

A joint account gives no right to sell a property, manage investments or access accounts held solely in the other person’s name.

What Happens If There Is No Power of Attorney in Place?

If someone loses mental capacity and no LPA exists, loved ones may have no legal right to manage their finances.

In that situation, the only option may be applying to the Court of Protection for a deputyship order.

This process is time-consuming (often several months) and more expensive, often making it more stressful for families to deal with. It is also subject to ongoing supervision and reporting requirements.

An LPA is widely considered the simplest and most cost-effective way to avoid these difficulties.

What Type of Power of Attorney Is Needed?

To manage bank accounts and finances, the relevant document is:

Property and Financial Affairs Lasting Power of Attorney

This allows your appointed attorney(s) to:

• Operate bank accounts.
• Pay bills.
• Deal with benefits and pensions.
• Manage investments.
• Buy or sell property if needed.

It can take effect either immediately (with permission), or only if mental capacity is lost. This flexibility makes LPAs an important planning tool for the future.

Is It Worth Having a Power of Attorney If You Are Married?

Yes. Marriage does not automatically give spouses the legal right to manage each other’s finances if capacity is lost.

Banks and financial institutions require formal legal authority before they allow anyone, even a spouse, to access or manage another person’s accounts.

An LPA ensures your spouse or chosen family member can step in without unnecessary delay.

How Do You Set Up a Lasting Power of Attorney?

Setting up an LPA involves:

1. Choosing your lawyer
2. Completing the required forms
3. Having signatures properly witnessed
4. Registering the LPA with the Office of the Public Guardian

Seeking legal advice ensures the document is valid, correctly completed and tailored to your circumstances.

Why Speak to a Solicitor About Powers of Attorney?

A solicitor can help you:

• Choose the right attorneys.
• Avoid common mistakes that cause delays at registration.
• Include appropriate safeguards and instructions.
• Ensure your finances and family are properly protected.

A well-drafted LPA offers peace of mind that your affairs will be managed smoothly if the unexpected happens.
