Travelling with LP and DC

[CrystalGlitz]

I'm travelling with a friend and her DC for a short break in Europe soon. She is acrimoniously divorced from her DC's father and I am worried that he wants to stop her leaving the UK with her child. Unfortunately he's a nasty man who has put her through years of emotional and physical abuse, and he is also a negligent parent.

I don't know whether he has PR but she is the resident parent. He wanted to take the DC to visit family that the child has never met, but my friend refused on the grounds that she couldn't trust him to return.

I am concerned that he will now act out of spite to put an alert on the DC's passport so that we can't travel. Is this feasible and has anyone had experience of this?
