Section 22 of the Marital Causes Act 1973 states as follows:
"On a petition for divorce ... the court may make an order for maintenance pending suit, that is to say, an order requiring either party to the marriage to make to the other ... periodical payments for his or her maintenance ... for ... a term beginning not earlier than the date of the presentation of the petition and ending with the date of the determination of the suit, as the court thinks reasonable."
