Clarification of Court Order Paragraph

Can anybody clarify what the following means:

2. There be leave, on 14 days notice, on the sale of the former matrimonial home, for the Respondent to bring this matter back to the Court for the purpose of reviewing paragraph 1 of this order and specifically the periodical payments.

Does it mean that at ANY time after the FMH is sold as long as 14 days notice is given then the matter can be returned to court

or

Only within 14 days from the date of sale of the FMH the respondent has the option to return the matter to court.

My interpretation is that permission is given for the Respondent to apply to review spouse maintenance giving 14 days notice when the house is sold.

Thank you for the response. But the question is can those 14 days be a week, a year or any length of time as long as it is after the sale. Is it forever an open option.

I think it would be within a reasonable time of the house selling to reassess the situation. Any other change of circumstance would require an application to vary SM requiring further hearings so the financial position of both parties would be looked at again.
