Upon her marriage to Prince Philippe of Belgium, the Duke of Brabant in 1999, King Albert II of Belgium elevated the family d'Udekem d'Acoz from the baronial to the comital rank, hereditary in the male lineage. Upon the accession of her husband, Prince Philippe, Duke of Brabant to the throne of Belgium she became the first Belgian queen consort of native Belgian nationality.

The announcement of Mathilde's engagement to the Belgian heir-apparent Prince Philippe came as a surprise to the country. Mathilde married Philippe on 4 December 1999 in Brussels, civilly at the Brussels Town Hall and religiously at the Cathedral of St. Michael and St. Gudula. Mathilde's bridal gown was designed by Édouard Vermeulen. She was made Duchess of Brabant and a Princess of Belgium on 8 November 1999 (published on 13 November 1999 and effective from 4 December 1999).

Mathilde worked as a speech therapist in her own practice in Brussels from 1995 to 1999. She also studied psychology at the Université catholique de Louvain and earned a master's degree in psychology in 2002 with honours (cum laude).

Mathilde attended primary school in Bastogne. She attended secondary school at the Institut de la Vierge Fidèle in Brussels, and then studied speech therapy at the Institut libre Marie Haps in Brussels from 1991 to 1994, earning a diploma with high honours (magna cum laude).

Princess Elisabeth, the couple's eldest child, is the first in line to the throne and ahead of her younger brothers and sister, who are second, third, and fourth in line to succeed, owing to a change in Belgian succession laws in 1991, allowing for the eldest child to succeed, regardless of gender.
