In 1832 Talbot claimed compensation from the Crown for the loss of customs and duties arising out of the port of Malahide granted to his ancestor Thomas Talbot (see MS. Talbot a. 1). The case was decided against him in 1834 and his subsequent appeal turned down in the following year. Between 1833 and 1837 he was involved in another dispute with the Crown over his claim to sit as a representative peer in the House of Lords. He failed in this cause also, though he was subsequently created Baron Furnival of Malahide in 1839 (see MS. Talbot b. 6*). In support of both claims Talbot amassed a large quantity of evidence in the form of copies of private and official documents, and papers relating to the 'Port' and 'Peerage' cases make up the bulk of his surviving papers.
