CHAPTER XXI 
POWERS OF ATTORNEY! 
THE capacity to appoint an attorney (and it should be Capacity. 
remembered that capacity primarily depends upon domicile) 
is practically co-extensive with the capacity to contract. 
Thus a power of attorney given by an infant is void [Zouch v. 
Parsons (1765) 3 Burr:], except for doing acts by which 
the infant himself could be legally bound. On the other 
hand, ‘an infant may be an agent, an infant may be the 
donee of a power of attorney’ [per James, L.J. in re 
D’ Angibau (1880) 15 C.D. 228]; for the acts of an agent as 
such are not his own but those of his principal, of whom 
he is merely an instrument. As regards married women, 
s. 129 of the Law of Property Act 1925 provides that 
‘a married woman, whether an infant or not, has power, 
as if she were unmarried and of full age, by deed to appoint 
an attorney on her behalf for the purpose of executing any 
deed or doing any other act which she might herself execute 
or do,? and the provisions of this Act relating to instruments 
creating powers of attorney apply thereto.” If a woman 
marries a foreigner, it may be that by the law of her new 
nationality and domicile she loses the capacity to appoint an 
attorney, and thereby becomes subject to ‘disability’ within 
the meaning of ss. 124, 126 and 127, set out below; otherwise 
marriage does not revoke a power. 
The capacity of trustees to appoint attorneys is regulated 
by ss. 23 and 25 of the Trustee Act, 1925. S. 23 gives an 
unqualified right of delegation where the trust property is 
out of the United Kingdom (which by s. 68 is defined to mean 
Great Britain and Northern Ireland). S. 25 provides that 
in other cases a trustee who intends to remain out of the 
United Kingdom for more than one month may, by power 
of attorney, delegate the execution of trusts, subject to the 
following qualifications: if he has only one co-trust:-, the
