LPA vs Court of Protection Deputyship: The Real Cost of Waiting

24th July 2026

If you’re in a situation where you’re searching for LPA vs Deputyship Costs, there’s a good chance you’re trying to understand what happens if someone loses mental capacity before making an LPA. It’s a situation thousands of families unexpectedly face every year, and one that often becomes far more expensive, stressful and time-consuming than people could ever realise.

Many people assume their husband, wife or adult children will automatically be able to help if something happens. Unfortunately, that isn’t how the law works in England and Wales. Without a registered Lasting Power of Attorney, families can find themselves needing to apply to the Court of Protection for a deputyship order instead.

On paper, both arrangements allow someone else to make decisions. In reality, they are two very different routes.

The biggest difference isn’t just the paperwork. It’s the loss of choice, the extra cost and the months of delay that can leave families unable to manage everyday finances when they’re needed most.

What deputyship is and when families are forced into it

Deputyship exists for situations where somebody has already lost the mental capacity to make their own decisions and had never created an LPA.

The Court of Protection can appoint someone, usually a close family member, to make decisions on their behalf. Depending on the circumstances, this may cover financial matters, health and welfare decisions, or even both.

Many people don’t even know deputyship exists until they’re suddenly faced with it after a stroke, advanced dementia, a serious accident or another unexpected illness.

By that point, there’s usually no alternative.

The upfront costs are only the beginning

Most people focus on just the court application fee, but that’s only one part of the overall picture.

Families will also need:

• a medical assessment confirming lack of capacity
• solicitor’s fees if they choose professional help, which is often sensible in the circumstances
• ID verification and document costs
• a security bond before financial authority is granted

Even straightforward applications quickly become significantly more expensive than just setting up an LPA in advance.

Where applications become contested or more complex, costs can rise much further again.

The ongoing costs many families don’t expect

Unlike an LPA, deputyship doesn’t simply end once the authority has been granted.

Most property and financial affairs deputies continue paying ongoing costs throughout the deputyship.

These commonly include annual supervision fees, deputy security bond premiums and yearly reports explaining how money has been managed during that period.

The OPG also monitors deputies to make sure they are acting appropriately in their role.

This oversight is important, but it does mean deputyship carries continuing responsibilities and costs that most people never anticipate when they first begin the application.

The timeline can create real problems

One of the biggest practical differences is how long everything can take.

An LPA created using a guided service like Power of Attorney Online can usually be prepared and submitted within days, with registration then taking place through the OPG.

Deputyship is a different beast.

Court applications frequently take many months before authority is eventually granted.

During that period, families may discover they can’t access bank accounts, sell property, deal with investments or manage everyday financial matters, unless another legal arrangement already exists of course.

Bills still need paying.

Care fees still need funding.

Mortgage payments don’t pause simply because legal authority hasn’t arrived yet.

This waiting period is often the most stressful part of the entire process.

The court decides who manages affairs

Perhaps the biggest difference is one people rarely consider.

An LPA lets you decide who you trust.

You choose your attorneys.

You decide whether they act together or independently.

You can include guidance about how you would like decisions to be made.

With deputyship, that choice has already gone.

The Court of Protection decides who should be appointed, and although family members are commonly approved, there’s no automatic right for a spouse or child to become deputy.

Where families disagree, the process can become even more complicated than that.

Five-year cost comparison

Registered LPA	Court of Protection Deputyship
One-off preparation costs	Court application fees
OPG registration fee	Medical evidence costs
No annual supervision	Annual supervision fees
No yearly reporting	Annual reports required
No deputy bond	Ongoing security bond
You choose your attorneys	Court chooses the deputy
Usually far lower overall cost	Often substantially higher over five years

Although every family’s circumstances differ, deputyship almost always becomes the more expensive route over time.

Can deputyship still be avoided?

Sometimes.

A diagnosis such as dementia doesn’t automatically mean someone lacks mental capacity.

Capacity is decision-specific and can change over time.

If someone still understands what an LPA is, what powers they are giving away, who they are appointing and the consequences of that decision, they may still be able to create a valid LPA at that moment in time.

That’s why acting early matters.

Waiting for a formal diagnosis is rarely the right milestone.

Waiting until someone can no longer make the decision often is.

How to close the gap this week

If you or someone close to you still has mental capacity, there are three realistic options.

The first is to complete the forms yourself using the official government process.

The second is to instruct a solicitor.

The third is to use a specialist guided online LPA service that guides you through the application while checking for common mistakes before submission.

Whichever route you choose, the important step is starting before capacity becomes an issue.

Once capacity has been lost, those choices usually disappear.

Frequently asked questions

Can deputyship be avoided after a dementia diagnosis?

Sometimes. A dementia diagnosis does not automatically remove mental capacity. If the person still understands the nature and effect of making an LPA, they may still be able to create one.

Who pays for deputyship?

Application fees and related costs are usually paid from the finances of the person who lacks the capacity, although applicants often have to pay certain fees upfront before being reimbursed where appropriate down the line.

Can deputyship be backdated?

No. Deputyship only gives authority from the date the Court of Protection grants the order. It can’t authorise decisions that were made before the appointment took place.

Planning ahead usually costs less than putting things right later

Nobody sets out expecting their family to need deputyship.

Most people simply assume they’ll have time to deal with an LPA later when they need to.

Unfortunately, life doesn’t always offer that opportunity.

A sudden illness, accident or diagnosis can change everything overnight.

Creating an LPA while you still have capacity gives you control over who makes decisions, usually costs considerably less than deputyship and can spare your family months of uncertainty at a time when they already have enough to cope with.

For many families, the real cost of waiting isn’t just measured in pounds. It’s measured in stress, lost time and decisions that become much harder once the opportunity to plan has, in effect, passed.
