Adults with Incapacity Scotland Act 2000: The Five Principles and What They Mean for Attorneys

The Adults with Incapacity (Scotland) Act 2000 is the legislation that governs every power of attorney, guardianship order, and intervention order in Scotland. It replaced a patchwork of common law rules with a single statutory framework, and at its core are five principles that bind everyone who makes decisions on behalf of an adult who has lost capacity.

These principles are not advisory. They are legal obligations. Financial attorneys are supervised by the OPG Scotland, while welfare attorneys are overseen through local authority social work. An attorney who consistently ignores them risks removal from their appointment.

The Five Principles

1. Benefit

Any intervention in the affairs of an adult with incapacity must directly benefit that adult. The benefit must be one that cannot reasonably be achieved without the intervention.

In practice: an attorney cannot sell a granter's property simply because it would be convenient for the family. The sale must benefit the granter — for example, releasing funds to pay care home fees or moving the granter to more suitable accommodation. If the same outcome could be achieved without the sale (such as using other savings), the property sale may not meet the benefit threshold.

2. Least Restrictive Option

Any action taken must be the least restrictive option available. The adult's freedom must be limited as little as possible.

In practice: a welfare attorney who places a granter in a care home when home care with additional support would meet their needs has not applied this principle. A continuing attorney who takes full control of all bank accounts when the granter only needs help with investment decisions is being more restrictive than necessary.

3. Wishes of the Adult

The decision-maker must take into account the past and present wishes of the adult, so far as these can be ascertained. This includes providing communication aids, interpreters, advocacy support, or other means to help the adult express their views.

In practice: a welfare attorney making decisions about medical treatment should consider any advance directive the granter made, conversations the granter had with family about their preferences, and the granter's known values and beliefs. The adult's wishes do not override the attorney's duty to act in their interest, but they must be genuinely considered and documented.

4. Consultation

Before making a significant decision, the decision-maker must consult the nearest relative, the primary carer, any named person in the POA deed, and any other relevant parties.

In practice: a continuing attorney selling the granter's house should consult with the granter's spouse, adult children, and anyone else with a close interest. They should record these consultations in writing. The duty is to consult, not to obtain consensus — the attorney makes the final decision, but they must show they sought views.

5. Encouraging Existing Skills

The adult must be encouraged to use whatever skills they have and to develop new ones. Decision-making authority should not become a reason to stop the adult from doing things they are still capable of doing.

In practice: if a granter can still manage small daily purchases but struggles with larger financial decisions, the continuing attorney should not take over all spending. The attorney should support the granter in maintaining the skills they still have.

How the OPG Enforces These Principles

The OPG Scotland supervises financial attorneys and financial guardians. Its enforcement powers include:

• Demanding financial records. The OPG can require an attorney to produce bank statements, receipts, invoices, and a full account of how the granter's money has been spent. Attorneys are legally required to keep detailed records.
• Investigating complaints. Anyone can report concerns about an attorney to the OPG. Investigations can include financial audits and interviews with the attorney and other parties.
• Referring to the Sheriff Court. If the OPG finds evidence of abuse or a failure to apply the principles, it can apply to the Sheriff Court for the attorney's removal.

Welfare attorneys are supervised by the local authority social work department, not the OPG. Welfare concerns should be reported to the adult protection team at the relevant council.

Why This Matters When Setting Up a POA

The five principles shape how attorneys should be selected. An effective attorney is someone who:

• Knows the granter well enough to understand their wishes and values
• Will consult family members rather than acting unilaterally
• Will keep records of decisions and their reasoning
• Will support the granter in doing what they still can, rather than taking over completely

Our Scotland Power of Attorney guide includes an attorney duties checklist grounded in these five principles, along with record-keeping templates and a practical guide to applying the least-restrictive principle.
