Firstly thank you very much for your answer. Would you be able to know below as well.

If he gets the place in either school, when do we need to provide the documents ? Is it in September 2021?
Can we move after September 2021 or do we need to live in the address some years in order to not to lose the place?

Many thanks

Fraudulent applications
Parents should note that Hertfordshire County Council will do as much as possible to prevent applications
being made from fraudulent addresses. Address evidence is frequently requested, monitored and checked and
school places will be withdrawn when false information is deliberately provided. Parmiter’s School will take
action in the following circumstances:
 When a child’s application address does not match the address of that child at their current school.
 When a family moves shortly after the closing date of applications or between the date of receiving
their child’s test results and the closing date of applications.
 Where information is received from a third party that an application is fraudulent.
 When a child starts at the allocated school and their address is different from the address used at the
time of application.
 When there are other suspicious circumstances.
