About the Adults with Incapacity (Scotland) Act 2000
The Adults with Incapacity (Scotland) Act 2000 ('the Act', or 'the AWI Act') provides a legal framework for safeguarding and managing the welfare, property and financial affairs of adults (age 16 or over) who lack capacity, due to mental disorder, acquired brain injury, learning disability, dementia or an inability to communicate.
The Act defines capacity in relation to decision making ability and to take account of the complexity of decisions to be made. A person is not deemed to lack capacity by diagnosis alone. The Act provides the legal authority to regulate and intervene in the affairs of the adult who may not have the capacity to make important decisions about their welfare or finances for themselves.
Any intervention in the life of an adult who lacks capacity, must take account of the AWI Act principles.

Social Work (Scotland) Act 1968 - Section 13ZA
S13ZA SW(S) Act 1968 allows for the provision of services to adults with assessed needs, who lack capacity to consent to receive services, such as arranging a move to a residential care home. This can only be applied where certain criteria are met.
Any provision of care should be compliant with Article 5 of the European Convention on Human Rights. There should be no deprivation of liberty. For further information on what constitutes a deprivation of liberty, see Mental Welfare Comission for Scotland advice notes - Deprivation of Liberty (pdf).
