How to choose between joint or jointly and severally attorneys: a practical guide

When you appoint more than one attorney in a lasting power of attorney, you must decide how they will make decisions. They can act jointly, meaning they must all agree, or jointly and severally, meaning any one attorney can act alone or with the others. You can also use a mixed approach, where certain decisions must be made jointly and everyday decisions can be made separately.

That choice affects how smoothly your affairs run if you lose mental capacity. Get it wrong and a well meant document can stall when your family needs it most.

What the two options actually mean

A lasting power of attorney lets you appoint people you trust to make decisions for you. There are 2 types: property and financial affairs, and health and welfare. Both must be registered with the Office of the Public Guardian before they can be used. A property and financial affairs LPA can be used once registered, with your permission, while a health and welfare LPA can only be used when you cannot make the relevant decision yourself.

If you are still weighing up whether to put one in place at all, the guide on setting up a lasting power of attorney is a sensible starting point. It also helps to understand the difference between an ordinary power of attorney and an LPA, because the rules are not identical.

Feature	Joint	Jointly and severally
How decisions are made	All attorneys must agree	Any attorney can act alone or together
If one attorney can no longer act	The others may be unable to act unless the LPA says otherwise	The remaining attorneys can usually continue
Speed	Slower, because all must be involved	Faster and more flexible
Oversight	Higher, because decisions are shared	Lower, because one attorney can act alone
Often suits	Small groups who communicate well	Families who want continuity and practicality

The trade-off most people miss

The biggest risk with a joint appointment is failure if one attorney can no longer act. If one attorney dies, loses capacity, steps down or becomes unable to act, the remaining attorneys may not be able to continue unless the LPA has been drafted to deal with that situation or a replacement attorney is available.

With a jointly and severally arrangement, the other attorneys can usually carry on. That resilience is why many people choose it. It does, however, rely on trust, because one attorney can make decisions without waiting for the others.

Picture a real situation. You appoint your 2 adult children jointly.

One moves abroad for work and cannot sign papers quickly. Every bill, transfer or property decision now waits for both signatures. A jointly and severally setup would let the other child deal with urgent matters. A joint appointment, by contrast, forces a conversation before anything happens, which some families prefer when large sums are involved. Knowing the responsibilities an attorney carries helps you decide how much oversight you need.

Who each option suits

A joint appointment can suit people who want every major decision checked by more than one person. It works best where attorneys live close by, communicate well and are unlikely to disagree. It may also appeal where money has caused tension before, because shared sign-off can reduce the risk of power of attorney abuse.

Jointly and severally suits many families because it keeps things moving. If one attorney develops health problems, is away or cannot respond quickly, the document can still work. That matters more as people age, which is why the note on lasting power of attorney and dementia is so useful. Either way, choose people who understand the limits of what an attorney can do.

Replacement attorneys deserve a mention. A replacement steps in if an original attorney can no longer act, and they are especially valuable with joint appointments. Many people also ask whether they can have more than one lasting power of attorney. You can, and the way you structure each one repays careful planning.

Getting the detail right

Attorneys often deal with big-ticket matters. One may need to manage a property sale, where solid conveyancing support keeps things on track. If you run a business, decisions about commercial premises could fall to them too. Where a spouse is your attorney and the marriage later breaks down, divorce solicitors in Sheffield can explain what that means for your documents.

Small drafting errors cause real delays. GOV.UK says registration currently takes 8 to 10 weeks if there are no mistakes in the application. The fee is £92 per LPA, so a property and financial affairs LPA plus a health and welfare LPA cost £184 in total. A 50% reduction may apply if the donor’s income before tax is under £12,000 a year, and exemptions may apply for some means-tested benefits.

Capacity is essential. You can only make an LPA while you understand what you are signing, which is why mental capacity sits at the heart of the law. If you later need to adjust your choice, the guide on how to change a power of attorney explains the process. For a steady second opinion, independent legal advice can help.

Frequently asked questions

What does jointly and severally mean?

Each attorney can make decisions alone or with the others. You do not need every signature for every action.

Is joint or jointly and severally better?

Neither is automatically better. Joint gives more oversight, while jointly and severally gives more continuity.

What happens if one joint attorney dies?

The remaining attorneys may be unable to act unless the LPA allows for it or a replacement attorney steps in. If a dispute follows, it helps to know who can override a power of attorney.

Can I change my mind after registering?

Yes, while you still have mental capacity. You can revoke or replace an LPA, but you will usually need to prepare and register a new document.

Talk to a solicitor before you sign

The wording on an LPA looks simple, but the consequences are not. A short conversation now can save your family months of frustration later.
