Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
How old is the child and how long has the child been in Poland
Your ex has no right to keep her in Poland without your prior agreement or an Order from the UK Court - and by doing so she is actually committing a Criminal Offence
You can apply to the Courts in Poland for the return of the Child to the UK.
You can get some held and advice form the Charity www.reunite.org.
You need to act promptly
Please ask if you need further details
