Practical Matters: legal, financial and safety

In plain English

A dementia diagnosis triggers a set of legal, financial and safety decisions that are easier to address while capacity is intact and harder to retrofit later. This section sets out what to do, in what order, and why. Each topic has its own page with detail.

The principle

The most important rule of practical planning in dementia: do the legal and financial groundwork as early as possible. A diagnosis of Mild Cognitive Impairment or mild dementia is exactly the right time. Capacity to make these decisions is preserved at that stage, and the planning makes everything that follows easier for you and your family.

Many of these arrangements (Lasting Power of Attorney, a will, an emergency contact list, vascular risk reduction, home safety) are good practice for any adult. A diagnosis simply gives them the priority they always deserved.

The first six months: priority list

  1. Lasting Power of Attorney for both health and welfare, and for property and finance. This is the single most important step. Register both LPAs while capacity is intact.
  2. Will. Update or write a new will if needed. Consider an advance decision to refuse treatment if relevant to you.
  3. Driving. Notify the DVLA of the diagnosis. Notify your motor insurer. A practical driving assessment may be required.
  4. Benefits. Check eligibility for Attendance Allowance, Personal Independence Payment, Council Tax reduction and Carer's Allowance.
  5. Home safety. Smoke alarms tested, hob safety, hot water temperature, key safe for entry, hallway lighting, removal of trip hazards.
  6. Mental Capacity Act. Understand how decisions are made when capacity is impaired.

Common questions about timing

Three questions families often ask:

Capacity over time

Mental capacity is decision-specific and time-specific. The same person may have capacity to decide about lunch but not about a major financial transaction; capacity may be present in the morning and impaired in the late afternoon. The Mental Capacity Act 2005 framework guides assessment and decision-making when capacity is impaired:

See the Mental Capacity Act page for detail.

If decisions need to be made without an LPA

If capacity is impaired and no LPA was put in place, family members may need to apply to the Court of Protection for a Deputyship. This is slower and more expensive than an LPA; it can take many months and several hundred pounds in court fees plus ongoing costs. This is the practical reason for doing LPAs early.

Where to find professional help

Where The Dementia Service fits in

Practical matters often emerge during a diagnostic conversation. A structured assessment letter from The Dementia Service provides a clear cognitive baseline that can support capacity assessments later, and an explicit recommendation to address LPA, driving and other priorities. Many families use the structured letter to brief a solicitor or the family conversation that follows.

Frequently asked questions

Is LPA expensive?

Government registration fees are £82 per LPA (so £164 for both) in England and Wales, with similar amounts in Scotland and Northern Ireland. Solicitor fees vary; many families use the government's online process directly.

Do I need a solicitor for an LPA?

Not strictly. The government's online process is workable for straightforward cases. A solicitor is recommended where the family is complex, there are significant assets, or there is any anticipated dispute.

Can I refuse to declare a diagnosis to my insurer?

Refusing to declare a material fact invalidates the policy. Even where premiums increase, declaring is the only safe option.

What is the difference between LPA and Deputyship?

An LPA is made by the person while they have capacity, naming attorneys to make decisions if needed. A Deputyship is granted by the Court of Protection after capacity is lost. LPA is far cheaper, quicker and more flexible.

Do I need to tell my employer?

Yes, where the diagnosis affects work or where you wish to use rights under the Equality Act 2010 (reasonable adjustments) or the Carer's Leave Act 2023. Most people find the conversation more positive than they feared.
