Joint vs Jointly and Severally: The One LPA Decision That Causes the Most Problems Later

29th July 2026

If you’ve searched for Joint vs Jointly and Severally, you’ve probably reached one of the most important decisions in a Lasting Power of Attorney application. It sounds like a technical legal phrase, but choosing whether your attorneys act jointly or jointly and severally can have a huge impact on how useful your LPA is in real life. We’ve reviewed hundreds of LPA applications, and this is one of the areas that causes the most uncertainty. Get it right and your attorneys have the flexibility to help when they’re needed. Get it wrong and, in some situations, the entire arrangement can stop working when you need it most.

Why this decision matters more than most people realise

Many people spend hours deciding who should become their attorneys. Far fewer spend time thinking about how those attorneys should work together.

That’s understandable. The wording feels technical and it’s easy to assume it makes little practical difference.

In reality, this single decision often determines whether an LPA continues working smoothly years later.

Life changes. People move abroad. Relationships evolve.

Someone may become seriously ill before the donor does.

An appointment that looked sensible when everyone signed the paperwork can create unexpected difficulties much later.

What each appointment type actually means

In simple terms, the difference comes down to whether your attorneys must always act together.

Appointment type	What it means in practice
Jointly	Every attorney must agree every decision and usually sign every instruction together. One attorney cannot act alone.
Jointly and severally	Attorneys can make decisions together or individually. If one attorney is unavailable, the others can usually continue acting.

This distinction applies throughout the lifetime of the LPA.

It affects everything from speaking to a bank to selling a property.

For many families, flexibility becomes increasingly valuable over time.

The joint appointment trap

Joint appointments often appeal because they sound safer. People assume requiring everyone to agree provides additional protection.

Sometimes it does. But there is an important trade-off.

Imagine parents appoint their two adult children to act jointly.

Ten years later, one child emigrates. Or develops their own health problems. Or loses mental capacity. Or simply decides they no longer wish to act.

Depending on how the LPA has been drafted and whether replacement attorneys have been appointed, the appointment may no longer work as intended. In some situations, the Property and Financial Affairs LPA can fail altogether.

Families are often surprised to discover that the issue is not disagreement. It’s simply that one attorney can no longer participate. The law can’t require someone who is unavailable to keep signing documents.

How banks deal with joint and jointly and severally appointments

Financial institutions pay close attention to how attorneys have been appointed. If attorneys act jointly, banks will usually expect instructions from everyone.

That may mean every attorney attending appointments, providing identification or approving important transactions.

For routine banking, this can become inconvenient. For urgent decisions, it can become a genuine obstacle.

Jointly and severally appointments are generally easier for organisations to administer because any one attorney can usually deal with day-to-day matters.

That doesn’t mean attorneys should stop communicating. Good attorneys continue discussing important decisions with each other wherever possible.

The legal flexibility simply makes practical life easier.

Hybrid appointments can work well, but only when drafted carefully

Some people want a middle ground. For example, they might want attorneys to act jointly when selling a property but jointly and severally for everyday banking.

The LPA allows this. These are often called hybrid appointments. When drafted clearly, they can reflect exactly how someone wants important decisions to be made.

The problem arises when instructions become unclear or contradictory. If the wording leaves uncertainty about who can make which decisions, the Office of the Public Guardian may raise queries.

In some circumstances, problematic wording may even be removed before registration if it cannot legally operate.

That can produce an outcome quite different from the one the donor originally intended. Clear drafting is therefore just as important as choosing the right appointment type.

What we see when reviewing applications

One of the most common areas where customers ask for reassurance is attorney appointments. Based on our own internal application reviews, attorney appointment wording is consistently among the top five sections where applicants ask us to double-check their choices before submitting their LPA.

That isn’t because the options are particularly complicated. It’s because people understand the decision could affect their family years into the future and want confidence they’ve chosen appropriately.

Often, the best solution isn’t about choosing the “right” option. It’s about choosing the option that best reflects how that particular family actually functions.

A simple decision framework

Every family is different.

The best appointment structure depends on how your attorneys are likely to work together over many years.

Your situation	Often worth considering
Two attorneys who live close by and make decisions together regularly	Jointly may be appropriate in some circumstances
Adult children living in different parts of the country	Jointly and severally often provides greater flexibility
One attorney travels frequently for work	Jointly and severally usually avoids delays
Several attorneys with different skills	Jointly and severally often works well while encouraging consultation
Important property decisions need collective agreement	A carefully drafted hybrid appointment may be appropriate

The important thing is thinking beyond today.

Ask yourself what life could realistically look like in ten or fifteen years.

Common misunderstandings

Some people worry that jointly and severally means attorneys can ignore one another. It doesn’t.

Every attorney still has exactly the same legal duty to act in the donor’s best interests. They remain accountable under the Mental Capacity Act.

Others assume appointing attorneys jointly prevents disagreements. Unfortunately, it can sometimes have the opposite effect. If everyone must agree every decision, even small differences of opinion can delay practical matters.

Choosing jointly and severally simply removes unnecessary procedural barriers. It does not remove legal responsibilities.

Replacement attorneys become even more important

Whichever appointment structure you choose, replacement attorneys deserve careful thought. A replacement attorney provides resilience if one of your original attorneys dies, loses capacity or no longer wishes to act.

Without replacements, unexpected life events can create avoidable complications years after the LPA has been registered. Many people spend considerable time choosing their first attorneys but only a few minutes considering replacements.

Given that LPAs often remain in place for decades, both decisions deserve equal attention.

The long-term view

An LPA applied for using a guided service like Power of Attorney Online is one of the few legal documents you hope will sit quietly in the background for many years. That means decisions should be based on what is likely to work in the future rather than what feels easiest today. The family dynamic you have now may not be the same one you have in twenty years.

Flexibility often becomes increasingly valuable as circumstances change. For that reason, many people find jointly and severally appointments better reflect the realities of modern family life.

Frequently asked questions

Is jointly or jointly and severally better?

Neither is universally better. Jointly provides more shared control, while jointly and severally offers greater flexibility if one attorney cannot act. The right choice depends on your family and circumstances.

Can attorneys still consult each other if they are appointed jointly and severally?

Yes. In fact, they should continue discussing important decisions wherever possible. The appointment simply allows one attorney to act when necessary.

Can I choose different arrangements for different decisions?

Yes. The LPA allows hybrid appointments, where attorneys act jointly for certain decisions and jointly and severally for others. These instructions must be drafted carefully to avoid ambiguity.

What happens if one jointly appointed attorney dies?

Depending on how the LPA has been written and whether replacement attorneys have been appointed, the appointment may fail or stop operating as intended. This is one reason many people prefer jointly and severally appointments.

Can I change my appointment later?

Yes, provided you still have mental capacity. You would normally need to make a new LPA reflecting your revised wishes.

Choosing the structure that will still work years from now

Most people focus on choosing the right attorneys. That’s important. Choosing how they work together is just as significant.

A well-chosen appointment structure gives your attorneys the flexibility to help when life becomes unpredictable while still protecting your interests. Taking a little extra time to understand the difference between jointly and jointly and severally can prevent significant problems later and help ensure your LPA works exactly as you intended when your family needs it most.
