Which documents do you need to update?
A meaningful change for your family. Requires cooperation from both parents in most cases.
What you'll need
- CRITICAL: Both parents with legal parental rights must typically consent
- If one parent has sole legal custody: a copy of the custody order may substitute for the other parent's consent
- If the other parent cannot be located: you may need to prove diligent search
- The court applies a 'best interest of the child' standard
- In some states: the child must consent if above a certain age (typically 12–14)
Common mistakes to avoid
- Failing to notify or properly serve the other parent
- Not having proper custody documentation
- Underestimating how thoroughly courts evaluate 'best interest' standard
- Forgetting to update the child's school, medical records, and passport
