Sigismondo was the son of Marquis Filippo II Francesco d'Este and Margherita of Savoy, legitimized daughter of the Duke of Savoy, Charles Emmanuel I.
In 1653, upon the death of his father, at only six years old, he inherited the titles and the fiefdom, under the regency of his mother.
On 18 November 1671 he married in Maria Teresa Grimaldi, in Turin, she was the daughter of Ercole Grimaldi, hereditary prince of the Principality of Monaco and Aurelia Spinola of the Principality of Molfetta, moving with her to a noble palace in via Santa Teresa 11, in the block of San Giuseppe, in the Santa Teresa district.
As representative of the House of Este at the Habsburg court, in February 1695 he accompanied Duke Rinaldo d'Este to Vienna to obtain the investiture of the Duchy of Modena and Reggio from Leopold I, Holy Roman Emperor.
On 28 November 1695, in the "Great Hall of the Ducal Palace" of Hanover, he represented Duke Rinaldo d'Este in the wedding ceremony with Charlotte Felicitas of Brunswick-Lüneburg , having already previously played a representative role in asking for the princess's hand in marriage to Duke Ernest Augustus of Brunswick-Lüneburg, his uncle.
On 20 July 1723 his wife Maria Teresa Grimaldi died in San Martino in Rio and was buried there in the family tomb of the Collegiate Church of Saints Martino and Venerio.
