Your son has no responsibilities or rights until the baby is born in any event.
If this woman continue sto harass him then he can ask the police to give her a warning.
Once the baby is born he can ask for a DNA test via the courts if necessary - or via the CMS if she applied for maintenance first.
Please ask if you need further details
