Vetting questions

[TS_]

I've been browsing around some insurance companies to get an idea of premiums etc and over a certain amount most specify that you must have a vet certificate. Some specify that it must be no older than 30 days, does that mean after 30 days a vet certificate is no longer reliable/usable. Or how long does it take for a vet certificate to no longer mean anything.
Just curious as don't know a lot about how it works, especially as a vetting only sees what is present on the day of the vetting.

Thanks for any help.

a vetting is only really accurate on the day of the vetting, as its the day the vet sees the horse, and anything could happen afterwards.

This is what I thought, but different people have told me different things so I thought I'd ask for some opinions on here.
