Short answer. You still need court action. Rule 131, Section 3 presumes an absent spouse dead for remarriage purposes after the stated period if there is a well-founded belief he is dead, but the same provision requires the present spouse to first institute the summary proceeding for a declaration of presumptive death before marrying again.
What the law says
If a married person has been absent for four [ ] consecutive years, the spouse present may contract a subsequent marriage if he or she has a well-founded belief that the absent spouse is already dead.

What the presumption actually says
Among the long list of disputable presumptions in Rule 131, Section 3 addresses exactly this situation: a married person who has been absent for four consecutive years, with the present spouse holding a well-founded belief that the absent one is already dead, is treated as having satisfied the belief requirement for contracting a subsequent marriage. Where the disappearance happened under circumstances involving danger of death, the same provision shortens that period to two years. On its face, this looks like the law simply letting time and honest belief do the work of proving death.
The clause that changes everything
The same section does not stop at describing the belief requirement — it goes on to say, in the very next sentence, that before marrying again the present spouse must institute a summary proceeding as provided in the Family Code and in the rules for declaration of presumptive death of the absentee. That is not an optional formality layered on top of an already-complete presumption; it is the mechanism the rule itself points to for actually establishing that the belief is well-founded, in a way a subsequent marriage can safely rely on and that protects against the absent spouse later reappearing.
Why the judicial step still matters
Skipping the court proceeding and remarrying based purely on personal conviction that four years have passed exposes the present spouse to serious risk: without a judicial declaration, the second marriage's validity can later be challenged, particularly if the absent spouse turns out to be alive and reappears, since the provision itself preserves the effect of that reappearance without prejudice. A court proceeding forces the present spouse to actually establish, through evidence a judge evaluates, that a diligent and honest search was made and that the belief in death is genuinely well-founded rather than convenient.
The practical takeaway
Someone in this situation should treat the four-year passage of time as a threshold that opens the door to the correct legal process, not as a self-executing basis to remarry on its own. The summary proceeding referenced in the rule is the step that converts an informal, disputable presumption into an actual judicial declaration a civil registrar and future spouse can rely on, and going through it protects everyone involved far better than assuming the presumption alone is enough to remarry safely.
