Statute of Limitations for Discovery Rule in Maryland

Overview

Maryland’s general statute of limitations is 3 years, and the discovery rule can delay when that 3-year clock starts running until the plaintiff knew or reasonably should have known of the claim. For reference-page purposes, the default Maryland limitations period is Md. Code, Cts. & Jud. Proc. § 5-106.

In practical terms, the discovery rule matters most when the injury, loss, or wrongful conduct was not immediately apparent. Instead of measuring from the exact date of the event alone, courts may look to when the claim was discovered, or should have been discovered through reasonable diligence. That makes the “start date” the critical input in any limitations analysis.

DocketMath’s statute of limitations calculator helps organize that analysis by comparing the event date, discovery date, and filing date so you can see how the time calculation changes. Use the calculator with the date you believe the claim accrued, then test whether a discovery-based start date changes the result.

Limitation period

Maryland’s general limitations period is 3 years. The default rule is straightforward: if a civil claim is subject to the general statute, the action must be filed within 3 years under Md. Code, Cts. & Jud. Proc. § 5-106.

The discovery rule affects accrual, not the length of the limitations period itself. That distinction matters:

• The period stays 3 years
• The clock may start later if the injury or cause of action was not reasonably discoverable earlier
• The filing deadline moves based on that later start date

A simple way to think about it is this:

For example, if a claim accrued on January 10, 2021, and the complaint was filed on January 9, 2024, it is generally within the 3-year period. If the discovery rule pushes accrual to March 1, 2021, the deadline would generally extend to March 1, 2024. The result changes because the start date changes.

That is why DocketMath asks for dates in a structured way. A calculator is only as good as the inputs, and Maryland discovery-rule analysis often turns on which date legally controls accrual.

Key exceptions

The main exception here is the discovery rule itself: the limitations period may begin when the claim was discovered, or should have been discovered, rather than on the underlying event date. For this reference page, no separate claim-type-specific rule was identified, so the general/default framework is the focus.

Here are the practical exception-style issues to watch for when using the discovery rule in Maryland:

• Delayed discovery of harm
  If the injury was hidden or not reasonably apparent, the accrual date may shift.
• Reasonable diligence
  Courts can ask when a person exercising ordinary care would have discovered the claim.
• Accrual disputes
  The fight is often not about the 3-year length, but about when the 3-year period started.
• Fraudulent concealment or concealment-like facts
  Facts showing concealment can affect timing analysis, but they are separate from the general rule and need careful review.
• Claim-specific statutes
  Some causes of action have their own limitation rules, but none were identified for this page’s baseline rule, so § 5-106 remains the default citation.

A few practical checks can help you assess the timing quickly:

If you are building a deadline workflow, the safest practice is to enter both the event date and the suspected discovery date into DocketMath and compare the output. That gives you a clearer view of the earliest arguable deadline and the later discovery-based deadline.

Statute citation

The Maryland general statute of limitations cited for this reference page is Md. Code, Cts. & Jud. Proc. § 5-106, which provides a 3-year period.

Citation details:

For a calculator workflow, the citation matters because the tool output should align with the governing period. If the matter falls under the Maryland general rule, the deadline calculation uses 3 years as the benchmark. If you enter a discovery date later than the event date, the deadline output should move accordingly.

Use the citation as the legal anchor in your notes, internal timelines, or case tracking records. That keeps the date math tied to the actual statutory framework rather than a guess or a calendar reminder alone.

Use the calculator

DocketMath’s statute of limitations calculator shows whether a Maryland claim is timely by measuring the filing date against the applicable 3-year period and the date the claim accrued.

The calculator is most useful when you want to test how the discovery rule changes the result. Enter the dates you know, then compare the deadline under different accrual assumptions.

What to enter

• Event date: When the underlying injury, loss, or act happened
• Discovery date: When the claim was discovered or should have been discovered
• Filing date: When the complaint or claim was filed
• Jurisdiction: Maryland
• Rule/period: General 3-year period under Md. Code, Cts. & Jud. Proc. § 5-106

How the output changes

If the event date and discovery date are the same, the calculator will usually produce the plain 3-year deadline from that starting point. If they differ, the output helps you see whether the discovery rule meaningfully extends the time to file.
