The legislative framework in Scotland

Legislation for deceased donation in Scotland is similar to the rest of the UK, but there are some key differences.

On this page: 

Overview of the legislation in Scotland

Deceased donation is governed by the Human Tissue (Scotland) Act 2006, which was amended by the Human Tissue (Authorisation) (Scotland) Act 2019 (the HTS Act).

The HTS Act 2019 introduced deemed authorisation, also known as the 'opt-out' system for organ donation in Scotland. This is similar to deemed consent in England, Wales and Northern Ireland.

Other key features of the Scottish legislation include:

  • the duty to inquire, which requires that certain checks are carried out to establish a potential donor's latest views on organ donation
  • a statutory framework for pre-death procedures, categorised into two types: Type A and Type B.


This page will cover these areas of the legislation in more detail, drawing on Scottish Government guidance on the HTS Act, which was published in 2021. The quoted sections on this page are from this guidance document rather than the legislation itself.

All NHS staff can access training on the Scottish legislation for organ and tissue donation. This includes eLearning modules, resources for trainers, a video and important links to further information.

Deemed authorisation

The main aim of the HTS Act 2019 was to introduce a system of deemed authorisation for donation. This is intended to increase the number of life saving or enhancing transplants each year.

When someone has not recorded their donation decision on the NHS Organ Donor Register, or elsewhere in writing, then authorisation for donation for transplantation may be deemed, subject to certain exemptions. This is known as an ‘opt out’ system.

Deemed authorisation and children

In Scotland, a child is defined as anyone under the age of 16 years. Deemed authorisation (the opt-out system) does not apply to children.

Children aged over 12 may provide express authorisation (opt in) or ‘opt out’ declarations either on the NHS Organ Donor Register or in writing.

If a child aged 12 or over did not make a valid decision or was not competent to do so, authorisation is usually taken from the individual holding parental rights and responsibilities (PRR). This is usually, but not always, their parents.

The duty to inquire and pre-death procedures framework described below apply to children as well as adults. 

Deemed legislation across the devolved nations

Deemed consent or 'opt out' legislation for organ donation has been introduced in all four nations of the United Kingdom (England, Scotland, Wales and Northern Ireland), and the Crown Dependencies of Jersey, Guernsey and the Isle of Man.

The concept of deemed consent/authorisation in each nation is broadly similar, but there are some subtle differences in the legislation. For example, there are differences in whose consent can or cannot be deemed. 

In Scotland, deemed authorisation does not apply:

  • if an expressed decision has been recorded in writing or the NHS Organ Donor Register
  • to those under 16
  • to people not ordinarily resident in Scotland for the last 12 months
  • if the person is incapable of understanding the nature and consequences of deemed authorisation, over a significant period
  • to excepted body parts
  • if there is no nearest relative to consult

In England, Wales and Northern Ireland, deemed consent does not apply:

  • if a donation decision has already been made (verbally or in writing)
  • to those under 18
  • to people who have lived in [England/Wales/Northern Ireland] for less than 12 months or are not living here voluntarily
  • to those who lack the capacity to understand the new arrangements and take necessary action
  • to novel transplants
  • if there is no family or friend of long standing to consult

The Specialist Nurses in Organ Donation (SNODs) are experienced in navigating the deemed consent legislation and will be able to confirm if deemed consent applies to an individual patient.

It's important to note that whilst the law may permit donation, it never mandates it.


Duty to inquire

Checking whether a decision has been recorded by a potential donor, exploring the most recent views of that person, and demonstrating that there is no evidence they were unwilling to donate are the key principles of 'duty to inquire'.

Chapter 6 in the Scottish Government guidance on the HTS Act states the following:

"The HTS Act respects the principle that the decision to authorise donation rests first and foremost with the donor themselves (in relation to adults and children aged 12 and over). As such, the potential donor's valid express authorisation where this is recorded, or the potential donor's views about donation, including where authorisation may be deemed, should form an integral part of end-of-life care planning.

"In every case where donation is a possibility, the SNOD/SR/TDC should establish whether, at the relevant time, there is a decision in force by the potential donor, in line with the requirements of the duty to inquire."

The duty to inquire usually involves discussion with the potential donor's family about donation, including about the potential donor's views about donation, to ensure that donation doesn't proceed where it would be against a person's wishes.

"The HTS Act requires that certain checks are undertaken before the carrying out of any pre-death procedure or retrieval can take place to determine a potential donor's status, any decisions which they may have recorded, and their views about donation and pre-death procedures.

"The duty to inquire may only be carried out by a health worker, which in most cases will be a SNOD/SR/TDC. If the duty to inquire is being carried out by a health worker who isn't a SNOD/SR/TDC then they should do so following discussion with the SNOD/SR/TDC."

Pre-death procedures

The HTS Act provides a new statutory framework for pre-death procedures, which is tailored to the practical and ethical issues relating to donation actions undertaken prior to a potential donor’s death.

A 'pre-death procedure' is defined as:

"A medical procedure which is carried out on a person for the purpose of increasing the likelihood of successful transplantation of a part of their body after their death and which is not for the primary purpose of safeguarding or promoting the physical or mental health of the person."

For detailed guidance on the legislation for pre-death procedures, visit chapter 8 in the guidance on authorisation requirements on the Scottish Government website.

The Donation Actions Framework may be useful in considering the appropriateness of actions where pre-death procedures do not apply.

Key points

Below are the key points from the guidance on the HTS Act about pre-death procedures.

Decisions about withdrawing treatment should be independent of any consideration of possible organ donation:

"Any decision about whether or not treatment should be withdrawn must be made purely in the interests of the patient and independently of any consideration of possible donation. It is important to give the patient's family time to come to terms with the probable death of a loved one, and to be able to consider fully all end of life options, including donation.

Guidance on pre-death procedures does not apply following death on neurological criteria:

"It is essential to be clear that up until the point at which the patient is confirmed to have died, the requirements of the HTS Act (as discussed below) must be followed in relation to any pre-death procedure. Once death has been confirmed, these requirements no longer apply and so this guidance does not need to be considered in relation to patients who have already been declared dead following brain-stem death testing."

Pre-death procedures can fall into two categories – Type A and Type B:

"The HTS Act makes provision for two different types of pre-death procedures - Type A and Type B procedures ... Type A procedures are those which are generally considered as routine procedures which would be needed to enable deceased donation to progress. Type B procedures are less routine and are generally more invasive."

Decisions about the timing and location of withdrawal of treatment are not considered 'pre-death procedures' under the HTS Act. These decisions will be guided by the specialist teams and will be specific to the individual circumstances.

Type A procedures

Depending on the outcome of the duty to inquire, Type A procedures will be considered to be authorised by the donor when either of the following applies:

  • they have expressly authorised deceased donation for transplantation (such as where they had opted in on the ODR)
  • their authorisation for donation is deemed under the HTS Act


The HTS Act also enables a person to expressly authorise pre-death procedures.

However, when authorisation for donation is given by a relative, authorisation for Type A pre-death procedures must be sought from that same relative:

"Where authorisation for donation for transplantation is given by the patient's nearest relative (or a person entitled to authorise donation on behalf of a child), then that person must also authorise the carrying out of a Type A pre-death procedure before it can proceed.

"The person authorising would normally be expected to authorise these as a group during the authorisation process, rather than needing to consider and authorise each test or procedure separately."

Type B procedures

Type B procedures are more invasive and/or rarely required procedures in a potential donor.

Before a Type B procedure may be carried out, two Registered Medical Practitioners (RMPs) must be of the view that carrying out the procedure is:

  • necessary
  • not likely to cause more than minimal discomfort to the person
  • not likely to harm the person


The two RMPs must also be of the view that it is not possible to obtain the required information by carrying out a Type A procedure.

The HTS Act guidance says:

"One of the RMPs must be the health worker primarily responsible for the person's medical treatment, which in most cases will be an ICU consultant. Neither of the RMPs can be part of the team involved in the retrieval or transplant process. A record of the agreement between the two RMPs must be made in writing."

Express authorisation of Type B procedures must be given either by the potential donor themselves or their nearest relative:

"Authorisation for the Type B procedure in question must be in place before it can be carried out. Authorisation may be given expressly by the donor themselves or by their nearest relative (or person entitled to give authorisation on behalf of a child)."
