Why Mistakes in an LPA Application Can Be a Serious Problem

Filling out a Lasting Power of Attorney (LPA) application online might seem like a straightforward task, but even small mistakes can cause major delays. Since your LPA needs to be registered with the Office of the Public Guardian (OPG) before it can be used, errors in your application could mean weeks or even months of waiting. In the worst-case scenario, your application could be rejected entirely, forcing you to start over from scratch. So, what happens if things don’t go smoothly? Let’s take a look.

Application Rejections Caused by Simple Errors

The OPG is very particular about how LPAs are completed. Simple mistakes, such as missing signatures, incorrect dates, or errors in wording, can result in your application being rejected. If this happens, you’ll have to go through the entire process again, which means more time, effort, and potentially more fees.

How LPA Delays Could Leave You Without Protection

One of the key reasons to set up an LPA is to ensure someone you trust can make decisions for you if you become unable to do so. But if there are mistakes in your application, the registration process could be significantly delayed, leaving you unprotected in the meantime.

Imagine you suddenly lose mental capacity due to illness or an accident, and your LPA is still being processed due to errors. Your chosen attorneys won’t be able to step in until the document is officially registered, meaning financial or healthcare decisions could be left in limbo.

Legal Complications for Your Loved Ones Without a Valid UK Power of Attorney

If your LPA is delayed or rejected, your loved ones may have no legal authority to manage your affairs. This could mean they are unable to access your bank accounts, pay bills, or make important healthcare decisions on your behalf. Instead, they may have to apply for a deputyship through the Court of Protection, which is a long and expensive process that could have been avoided with a correctly registered LPA.

Common Mistakes That Cause LPA Delays

Some of the most common errors that can slow down your LPA registration include:

• Incorrect signatures – The document must be signed in the correct order, and missing a signature can result in rejection.
• Ambiguous instructions – If your wording is unclear or contradicts itself, the OPG may refuse to accept your application.
• Using the wrong form – There are different types of LPAs (Property & Financial Affairs and Health & Welfare), so using the incorrect form can cause delays.
• Failing to notify people – If you’ve named people to be notified about your LPA but fail to inform them properly, it could cause issues.

How to Avoid Mistakes in Your LPA Application

The best way to avoid mistakes is to use an online LPA service that provides clear guidance and error-checking before you submit your application. Many platforms have step-by-step instructions to ensure you complete everything correctly, reducing the risk of delays.

Taking the time to double-check your application and making sure everything is in order can save you weeks, or even months, of waiting.
