It depends.
If you child is actually a child, then if someone refuses to return your child to you upon your request, you are arguably acting to prevent a crime, which gives you some leniency in terms of use of force. Also makes it less likely you’ll be charged even if you technically broke a law in the process.
You are not going to court if you walk into a house at 1AM to recover a 15 year old girl who's being held against their will. But if you kick the door down on a birthday party, and threaten the clown because you changed your mind about letting your 9 year old go to a party... you're probably getting arrested.
If your 'child' is a legal adult, (which they may or may not be at the age of 16), and are in said house of their own volition,it's a different matter.
