The stress of the Custom House contract led to the death of Henry Peto on 15 September 1830. Although he left a considerable estate, with income of about £12,000 per annum, there were mortgages of between £7,000 and £8,000 per annum and some annuities (i.e. pensions) of about £3,000 per annum, leaving only a small balance. There was also a continuing lawsuit regarding the Custom House. In his will he left his building business to his two nephews, Thomas Grissell and Morton Peto. The will was contested by Henry's widow on the grounds of undue influence by the two nephews as they and the solicitor were the only people present when Henry signed the will just a few days before his death. Henry's widow eventually lost in the courts and the two nephews, now in partnership as
Grissell and Peto were free to begin building up the business. ==References==
