Wigoder, whose father was a dentist, and mother a judge, studied history at Oriel College, Oxford, after attending Manchester Grammar School.

After being called to the Bar, he dealt mainly with criminal law and was introduced in 1951 by his lawyer A. P. Marshall in the case Willcock v Muckle, which led to the end of the use of identity cards from the war.

Like many other barristers, Wigoder also engaged in politics and ran in the 1945 United Kingdom general election, and in a by-election on 15 November 1945 for the Liberal Party in the Bournemouth constituency.

On 20 April 1966 Wigoder was appointed for his legal services to the Crown lawyer (Queen's Counsel),[2] and then dealt with many significant cases before the Old Bailey, the Central Criminal Court.

Afterwards he was a sought after defence lawyer and had over time known clients such as the former Paymaster General George Wigg, who was acquitted in a case of prostitution, or Sheila Buckley, a lover of former Labour Party politician John Stonehouse, who was sued for simulating suicide in 1974.

His other clients included the House of Commons journalist and later Conservative Member of Parliament Jonathan Aitken, who was charged in 1971 under the Official Secrets Act for passing classified information about the Biafra war to the weekly The Sunday Telegraph.

[3] During this time he was with the Attorney Lewis Hawser, who was co-chair of a Judiciary Committee, which proposed the transfer of criminal proceedings from the police to an independent public prosecution authority.

He married Yolanda Levinson in 1948 and had four children, including the businessman and business manager Charles Wigoder, who is also executive chairman of the telecommunications company Telecom Plus.
