Hi, thank you for your question. Firstly, a breach of an occupation (and if it also states on the order a non-molestation order) is a criminal offence and she would be able to call the police regarding this breach - however, you have a defence in the form of her letters allowing you access to care for the children, which would be considered reasonable to breach the occupation order. Upon her return you may wish to discuss applying to have the order discharged as she clearly does not think it is necessary.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you
