Custody as a father in California

STATUTORY

The factors, in plain words

• The health, safety and welfare of the child (Cal. Fam. Code §3011(a))
• A history of abuse by a parent or person seeking custody against the child, the other parent, or a parent, spouse, cohabitant or dating partner (independent corroboration may be required) (Cal. Fam. Code §3011(a))
• The nature and amount of the child's contact with both parents (Cal. Fam. Code §3011(a))
• Habitual or continual illegal drug use, alcohol abuse, or abuse of prescribed controlled substances (Cal. Fam. Code §3011(a))

§3020: health, safety and welfare is the primary concern; frequent and continuing contact with both parents is also policy - if they conflict, safety wins (§3020(c)). §3010: mother and presumed father are equally entitled to custody. §3044 adds a rebuttable presumption AGAINST custody/visitation for a parent found to have perpetrated domestic violence within the previous 5 years. Source list: Cal. Fam. Code §3011(a); policy §3020; ordering §3040

Presumption status

agreement-only · Cal. Fam. Code §3080

Frequent-and-continuing-contact (§3020) is a policy, not a time presumption.

Burden: Not applicable as an equal-time burden; §3080 presumes joint custody is in the child's best interest only when both parents agree to it

The paternity gate in California

Form: Voluntary Declaration of Parentage (VDOP) - form CS 909 / DCSS 0909

Authority: Cal. Fam. Code §§7570-7577; §7611; §7630 et seq. (Petition to Determine Parental Relationship, form FL-200)

Rescission window: Within 60 days (§7575)

No default-custodian rule stated for CA in sizing §3. A filed VDOP establishes paternity with the same force and effect as a judgment and is a basis for establishing a custody, visitation or support order (§7573) - it is not itself a custody order. Being named on a birth certificate alone, without marriage or a VDOP, does not establish parentage.
