When my son was born he was born with his last name, the first time we went to court I had my last name added. My sons last name is hyphenated with both names. His father signed all the docs and the birth cert was changed. He is not happy with it now. My son knows his hyphenated name. His father is angry with me and will not acknowledge his complete name. he has all of his family members telling him his name is not hyphenated. How can I stop him from confusing my son. Will the courts do anything about this form of manipulation. My son is 6.
