§ 50 (1) Sub-paragraphs (3) and (4) apply if—
- (a) a periodical payments or secured periodical payments order in favour of a civil partner ("R") has ceased to have effect because of the formation of a subsequent civil partnership or marriage by R, and
- (b) the person liable to make payments under the order ("p") (or P's personal representatives) has made payments in accordance with it in respect of a relevant period in the mistaken belief that the order was still subsisting.
§ (2) "Relevant period" means a period after the date of the formation of the civil partnership or marriage.
§ (3) P (or P's personal representatives) is not entitled to bring proceedings in respect of a cause of action arising out of the circumstances mentioned in sub-paragraph (1)(a) and (b) against R (or R's personal representatives).
§ (4) But, on an application under this paragraph by P (or P's personal representatives) against R (or R's personal representatives), the court—
- (a) may order the respondent to pay to the applicant a sum equal to the amount of the payments made in respect of the relevant period, or
- (b) if it appears to the court that it would be unjust to make that order, may—
- (i) order the respondent to pay to the applicant such lesser sum as it thinks fit, or
- (ii) dismiss the application.
§ (5) An order under this paragraph for the payment of any sum may provide for the payment of that sum by instalments of such amount as may be specified in the order.
§ (6) An application under this paragraph—
- (a) may be made in proceedings in the High Court for leave to enforce, or the enforcement of, payment of arrears under the order in question, but
- (b) if not made in such proceedings, must be made to a county court;
§ (7) The jurisdiction conferred on a county court by this paragraph is exercisable even though, because of the amount claimed in the application, the jurisdiction would not but for this sub-paragraph be exercisable by a county court.
§ (8) Subject to sub-paragraph (9), the collecting officer of a court of summary jurisdiction to whom any payments under a payments order, or under an attachment of earnings order made to secure payments under a payments order, are required to be made is not liable—
- (a) for any act done by him in pursuance of the payments order after the date on which that order ceased to have effect because of the formation of a subsequent civil partnership or marriage by R, or
- (b) for any act done by him after that date in accordance with any statutory provision specifying how payments made to him in compliance with the attachment of earnings order are to be dealt with.
§ (9) Sub-paragraph (8) applies if (and only if) the act—
- (a) was one which the officer would have been under a duty to do had the payments order not ceased to have effect, and
- (b) was done before notice in writing of the formation of the civil partnership or marriage, was given to him by or on behalf of R, P, or R or P's personal representatives.
