When do maintenance payments stop? Ambiguous Court order wording

[DownMexicoWay]

My husbands court order states that he stops paying his ex global maintenance on either his youngest child turning 18, or his youngest child ending full time education (whichever is the latest).

His youngest daughter turns 18 next April and takes her A levels in the may and then leaves college.

He plans on making his last payment on the first June. (He pays monthly in advance) so taking the maintenance up until the end of June.

Does this sound right?

Sorry... that should say when his youngest ceases SECONDARY education, but full time education.

NOT full time education. Ugh. Texting on a train....

Sounds right if she finishes school at the end of June after her exams. What is your concern ?

Sounds right. She is classed as full time until she has done her exams.

When do you think he should stop?

Just confirm it is secondary education ...
What happens if she fails exams and goes back to re-sit?
Child Benefit stops at either 31 May or 31 August, depending on the precise school/college leaving date.
But, on balance 1-June sounds right.
Is it worth 'reminding' the Ex- about this ???
