Yes, Children should always have an attorney present while being questioned.
Not in most countries - there legal guardian of the child would normally have to be present.
Police can question anyone if they have the proper authority (e.g. warrant), but a parent or guardian is authorized to be present during questioning of a child.
In New York State, a mentally challenged 16-year-old child can generally be questioned by the police without their parents present if they are considered competent to understand and participate in the questioning. However, it is recommended that parents or guardians be present during the questioning to ensure the child's rights are protected.
The short answer is no - the long answer is yes, depending on the circumstances. If you sustained injuries, you can sue for punitive damages regardless of the child's age. Parents of the child cannot necessarily sue the parents unless they were negligent in the care or restraint of the child. For example, you cannot sue the parents of the child if they weren't present, however, you can sue the parents if they were present and did nothing to restrain the child from assaulting you.
This depends on the state where the interview takes place. In some states, police can interview juveniles without a parent or advocate present. In cases where a parent is suspected of criminal misconduct, a court-appointed advocate is usually present to protect the child's interests.
no because he/sheis to young
I believe in this situation England has the same laws as the US in which police cannot question anyone under the age of 18 alone however, a 17 year old may give consent to be questioned without a guardian present, anyone younger cannot be questioned whatsoever without a guardian.
Not really enough specific information; The age of the "child" is not stated and, no definiton of "speak with" is given. As a general rule you cannot forbid it, especially if they are investigating a crime or offense and your "child" is suspected of having knowledge of it, or is a suspect or a witness. However, if the child is truly a juvenile, and they are being questioned in a custodial situation, you DO have the right to either be present, or witness, the interrogation.
No, a child does not have to be present to obtain a passport.
yes
In many states, yes. The legality of this may also depends on the circumstances and reasons the child is being questioned. A search may take place at any time if the person in the custody of the police might have evidence that could be destroyed or disposed of, or the person may be carrying weapons that could be used to harm the officer(s).
