The Question:
How do I file for joint custody if I don’t have a valid address for the father? My son is 15 and has moved five times in eight months. The father is abusive, and my son doesn’t want to stay there.
RJ Says:
Not knowing the other parent’s current address should not stop you from taking action to protect your child. If there are existing custody orders, the right step is to file a Petition to Modify Legal Decision-Making and Parenting Time based on a substantial and continuing change in circumstances.
If the father cannot be located, Arizona law allows for alternative service—but only after you’ve shown that you’ve made reasonable efforts to locate him. Here are some steps you can take:
Check existing court records for last known addresses
Search public databases, such as voter registration or property records
Use online tools like Spokeo, Whitepages, or BeenVerified
Contact mutual acquaintances—friends, family, or coworkers
Hire a private investigator
Review social media for recent activity or location clues
If these efforts are unsuccessful, you can request court approval to serve him through alternate means (such as publication or another method likely to provide actual notice). The court will require documentation of your search efforts before granting this request.
Importantly, your son’s frequent moves and statements about not wanting to return to the father’s home may support a change in parenting time—especially if abuse is a concern. The court will evaluate what arrangement best serves your son’s safety and stability.
