Maria Theresa promised her a splendid dowry and an annuity from the Spanish court, but the bride remained opposed to the match. The wedding, planned for the end of 1768, had to be postponed several times as Pope Clement XIII refused to issue the necessary dispensation because of his disputes with House of Bourbon. When he died in February 1769, his successor, Clement XIV authorised the marriage immediately.
Maria Theresa made a significant promise to the bride, including a generous dowry and an annuity from the Spanish court, but the bride remained unwilling to accept the proposal.
