Can an LPA Be Used Immediately?
An LPA cannot be used until it has been registered. Here is what you need to know about the timeline.

This catches many families off guard. A parent has a stroke, the LPA was signed last month, and the family takes it to the bank — only to be turned away. Until an LPA is registered with the Office of the Public Guardian (OPG), it has no legal force whatsoever. This is a firm requirement under the Mental Capacity Act 2005, and there are no exceptions. An unregistered LPA is simply a signed piece of paper.
At a glance
- No, an LPA cannot be used immediately after signing — it must first be registered with the OPG
- Registration typically takes 8 to 10 weeks and costs £92 per LPA
- A Property and Financial Affairs LPA can be used as soon as it is registered, even while the donor has capacity
- A Health and Welfare LPA can only be used once the donor lacks mental capacity for the specific decision
Why Registration Is Required Before an LPA Takes Effect
The registration requirement exists to protect donors from potential abuse. During the registration process, the OPG carries out checks on the document, notifies any people the donor has named to be informed, and allows a window for objections. This safeguarding process ensures that:
- The LPA has been properly completed and signed in the correct order
- The donor understood what they were signing and was not being coerced
- Anyone with concerns about the arrangement has the opportunity to raise them
- The attorneys named are eligible and suitable to act
Without this process, there would be no independent oversight of who gains control over another person's finances, health, or welfare. For a full walkthrough of the submission process, see our guide on how to register an LPA with the OPG.
Important: If someone presents an unregistered LPA to a bank, hospital, or care home, it will be refused. The organisation has no legal obligation to act on an unregistered document, and doing so could expose them to liability.
How Long Does Registration Take?
The OPG aims to process LPA registrations within 8 to 10 weeks from the date they receive the application. However, timescales can vary depending on:
Named Persons
If the donor named people to be notified, the OPG must allow the statutory 3-week objection period before proceeding.
Errors in the Document
If the OPG finds mistakes, they may return the LPA for correction, adding weeks or months to the process.
OPG Workload
Processing times can be longer during busy periods. The OPG publishes current estimated timescales on their website.
Objections
If someone raises a formal objection, the registration is paused while the OPG investigates, which can take considerably longer.
The Two Types of LPA: Different Rules After Registration
Once registered, the two types of LPA have different rules about when they can actually be used:
Property & Financial Affairs LPA
Can be used as soon as it is registered, even while the donor still has full mental capacity. The donor can choose to add a restriction so it can only be used once they lose capacity, but this is not the default. This type of LPA is often used during the donor's lifetime for convenience, such as delegating banking tasks.
Health & Welfare LPA
Can only be used once the donor lacks the mental capacity to make a specific decision for themselves. This is a fixed rule set by the Mental Capacity Act 2005 and cannot be changed, even if the donor wishes otherwise. While the donor has capacity, they make their own health and welfare decisions.
Why You Should Register Your LPA Early
Given that registration takes 8 to 10 weeks, the case for registering early is compelling. If you are thinking "I'll register it when I need it," consider these scenarios:
- If a parent suffers a stroke and their LPA is not yet registered, their family cannot access bank accounts to pay for care during the 8 to 10 week registration period
- If someone is diagnosed with a progressive condition like dementia, early registration ensures the LPA is ready before their capacity deteriorates
- If the donor passes away before the LPA is registered, the registration fee (£92 per LPA) is lost and the document becomes void
- If errors are found during registration, the delay could stretch to several months
Key point: There is no cost or disadvantage to registering early. The £92 fee is the same whether you register now or in ten years. The only risk is waiting too long.
What to Do in an Emergency Without a Registered LPA
If someone loses capacity and there is no registered LPA in place, the options are limited and significantly more costly:
Apply to the Court of Protection
A family member can apply to become a Deputy through the Court of Protection. This process typically costs over £1,000 in court and legal fees, takes several months, and requires ongoing annual supervision and reporting to the OPG. The court decides who becomes Deputy — it may not be the person you would have chosen.
Emergency or Interim Orders
In urgent cases, it is possible to apply for an interim order from the Court of Protection, but this is expensive, stressful, and not guaranteed. It is a last resort, not a substitute for proper planning.
Medical Decisions Without an LPA
If there is no Health & Welfare LPA, medical professionals will make treatment decisions based on their assessment of the patient's best interests. They will consult family members where possible, but the final decision rests with the medical team, not the family.
The Registration Timeline at a Glance
Here is a realistic timeline from deciding to create an LPA to having a fully usable document:
- Week 1–2: Complete the LPA questionnaire and gather details of attorneys, replacement attorneys, and certificate provider
- Week 2–3: LPA documents prepared and reviewed
- Week 3–4: Documents signed by the donor, certificate provider, attorneys, and witnesses (in the correct order)
- Week 4: LPA submitted to the OPG with the £92 registration fee
- Week 4–7: OPG notification period for named persons (3 weeks)
- Week 7–14: OPG completes checks and returns the registered LPA
In total, the process from start to finish is typically 3 to 4 months. This underscores why it is so important to start early rather than waiting for a crisis.

Key Takeaways
- An unregistered LPA has no legal force — banks, hospitals, and care homes will refuse to accept it; the attorney has no authority to act until registration is complete
- Registration takes 8 to 10 weeks — this can stretch longer if there are errors in the document or if objections are raised during the notification period
- Register early, not when you need it — there is no cost or disadvantage to registering now; the £92 fee is the same whether you register today or in ten years
- Without a registered LPA, the Court of Protection is the only option — deputyship costs over £1,000 to set up, takes months, and involves ongoing supervision
- Total timeline is 3 to 4 months — from starting the LPA process to having a fully registered, usable document
What You Need to Know
Can I use an LPA that has been signed but not yet registered?
No. An unregistered LPA has no legal effect whatsoever. Banks, hospitals, and care homes will refuse to accept it. The LPA must be registered with the Office of the Public Guardian before an attorney has any legal authority to act.
How long does it take to register an LPA with the OPG?
The OPG aims to process registrations within 8 to 10 weeks, but it can take longer if there are errors in the document, if named persons raise objections, or during busy periods. This is why registering early — well before the LPA is needed — is strongly recommended.
Can a Health and Welfare LPA be used while the donor still has capacity?
No. A Health and Welfare LPA can only be used once the donor lacks the mental capacity to make the specific decision in question. This is a fixed rule under the Mental Capacity Act 2005 and cannot be changed, even if the donor wishes otherwise.
