Filing deadlines for a child's social media claim in Missouri

The question every parent asks first is whether it is already too late. In Missouri the answer turns on one provision, and it is not the same provision that governs an adult's claim.

While under 21

Generally paused

After 21

The standard period

Outer limit

No cap on this ground

In Missouri, the time a child spends under 21 is generally not counted against the claim, and once they reach 21 the claim must be brought within the standard period. Note the age: Missouri sets it at 21, not 18, on the face of this provision. That comes from Mo. Rev. Stat. § 516.170.

Two situations, and they are not close

The child is still under 21

A parent or legal guardian brings the claim. The clock generally has not started, so a family that assumes it is too late is usually wrong about that.

They are an adult now, harmed as a teenager

They bring the claim themselves, and the clock is running. Missouri's personal injury period is 5 years. These cases have been accumulating since 2022, so this is a large group rather than an edge case — and it is the situation where timing is genuinely urgent.

Missouri also recognizes the discovery rule, which can matter here: families rarely connect a child's deterioration to platform design at the time, and often only make that connection years later.

Missouri deadline questions

Is it too late to bring a Missouri social media claim for my child?

A claim belonging to a child is treated differently from an adult's, which is why the answer is not simply the two- or three-year figure people expect. In Missouri the time a child spends under 21 generally does not count against them, so the window opens rather than closes on their birthday. No outer limit in this section cuts the claim off while the child is still a minor. None of that is a determination about your family's dates — it is the rule a Missouri claim would be measured against.

What if the person who was harmed is already an adult?

Then the pause, if it applied, has ended and the clock is running. Missouri's personal injury period is 5 years, and after 21 a claimant generally has the standard period. Social media addiction claims have been accumulating since 2022, so a claimant who was 14 when the harm began may well be an adult now — which is the situation where timing is genuinely urgent rather than theoretical.

Who has to bring the claim while the child is still a minor?

A parent or legal guardian. A minor cannot retain counsel or sue in their own name; the court appoints a guardian ad litem to act for the child in the case, which is a filing the trial firm makes rather than anything handled at intake.

Does waiting hurt the claim even if the deadline has not passed?

It can, and for reasons that have nothing to do with the statute. School and counseling records get purged, platform data ages out, and the family's own account of what changed and when is sharpest closest to the events. A deadline that has not passed is not the same as no reason to move.

Have the dates checked, either way

Do not conclude a claim is out of time, and do not conclude it is safe, without someone reading Missouri's provision against your family's actual dates. The review is free and takes a few minutes.
