Hello Kitkat44,
Your children should not immediately loose their school places if you need to temporarily withdraw them due to having to flee domestic abuse.
However, some of the time, children will be re-enrolled in a new school within the area of the temporary accommodation. For example, if you were to go into refuge in a different area, the refuge can help enroll the children into a school in the new area, this can be a long or short term arrangement.
All schools should have policies and procedures when it comes to domestic abuse so it may be worth speaking with the school about this, if it is safe to do so.
Take care and keep posting,
Lisa
