In child custody cases, a New York Court will sometimes appoint a guardian for the children. A guardian is usually an attorney whose job it is to represent the child or children, and to express their needs to the court. You need to keep in mind that any conversations you have with the guardian are not privileged attorney-client communication, and whatever you say, write or do can be used against you. Even things that you would expect to help you may be damaging. For example, it's not a good idea to make criticisms about your spouse to the guardian. This gives the impression of a tendency towards parental alienation, something courts take a very dim view of and can hurt your case.
