Short answer. Three months. A spouse who has left the conjugal dwelling for three months, or who has failed within that same period to give any information about their whereabouts, is prima facie presumed to have no intention of returning — which the law treats as abandonment absent just cause.

What the law says

The spouse who has left the conjugal dwelling for a period of three months or has failed within the same period to give any information as to his or her whereabouts shall be prima facie presumed to have no intention of returning to the conjugal dwelling.

Three months triggers the presumption, in either of two ways

The statute gives a specific, measurable trigger: three months. That period activates the presumption in either of two ways — the spouse has physically been away from the conjugal dwelling for three months, or the spouse has failed, within that same three-month period, to give any information about their whereabouts. Either one on its own is enough to bring the presumption into play; the spouse does not need to satisfy both.

What the presumption actually establishes

Once three months have passed under either scenario, the absent spouse is prima facie presumed to have no intention of returning to the conjugal dwelling. This connects to the article's broader definition: a spouse is deemed to have abandoned the other specifically when they have left the conjugal dwelling without intention of returning. The three-month rule supplies the evidentiary shortcut for proving that missing intention, rather than requiring direct proof of what was going on in the absent spouse's mind.

"Prima facie" means it can be rebutted

The presumption is explicitly prima facie — it stands unless overcome by evidence to the contrary. A spouse who was away for three months but can show a genuine intention to return, or a reasonable explanation for the silence about their whereabouts, is not conclusively deemed to have abandoned the family simply because the three months passed. The presumption shifts the practical burden of proof, but does not by itself settle the question beyond dispute.

This presumption feeds into the remedies the article provides

This three-month rule matters because abandonment, established with just cause absent on the departing spouse's side, is what opens the door to the remedies the article describes for the aggrieved spouse — petitioning the court for receivership, judicial separation of property, or authority to be the sole administrator of the community property. The presumption is the evidentiary bridge that helps establish the abandonment those remedies are built around, though the underlying obligations referred to in the article cover marital, parental, or property relations more broadly.
