Rule or statute summary

Run this scenario in DocketMath using the Statute Of Limitations calculator.

In Wyoming, there isn’t a clearly identified, mortgage-deficiency-specific statute of limitations in the jurisdiction data you provided. Instead, mortgage deficiency claims (often understood as the unpaid balance after foreclosure) are generally analyzed using Wyoming’s default “catch-all” / general limitations period, when no more specific provision applies.

Based on your supplied rule, DocketMath’s statute-of-limitations approach uses:

General SOL period: 4 years
General statute: **Wyo. Stat. § 1-3-105(a)(iv)(C)

Because no claim-type-specific sub-rule was found for mortgage deficiencies in the materials provided, this post is best read as a general/default limitations framework, not a guarantee that every lender pleading will fall under the same rule. Different pleadings can be framed under different legal theories (for example, contract, promissory note, or another theory), and Wyoming’s limitations analysis may change if a different statute fits the asserted cause of action.

Practical caution: The “mortgage deficiency SOL” can shift if the plaintiff sues using a different legal theory or relies on a different limitations provision. Use this as a starting point, and verify the exact cause of action asserted in the complaint.

Wyoming default (general) limitations period:
Wyo. Stat. § 1-3-105(a)(iv)(C) provides a 4-year limitations period for the general categories it covers. Per the jurisdiction data provided, DocketMath applies this 4-year default when a mortgage deficiency claim is not tied to a more specific statute.

How the rule is usually applied:
In practical terms, the core question becomes: how long after the relevant trigger date can the lender file suit consistent with the 4-year period under Wyo. Stat. § 1-3-105(a)(iv)(C)?

In foreclosure-related matters, the “trigger” can be disputed. Common candidates include dates connected to:

default
acceleration (if the loan documents allow it and acceleration occurred)
final demand (if required for the claim asserted)
foreclosure / deficiency timing (if you argue accrual aligns with that event)

DocketMath’s calculator reflects the general/default framework based on your chosen start date.

Use the calculator

DocketMath’s statute-of-limitations tool turns the Wyoming 4-year general period into a filing deadline by using your selected start date (the date you believe the SOL begins running for the claim you’re analyzing).

Step-by-step: what to enter

Jurisdiction:

**Wyoming (US-WY)

Rule basis:

Use the general/default limitations period because no mortgage-deficiency-specific sub-rule was found in the provided jurisdiction data.

Start date (case-relevant):
Choose the date you believe best marks when the claim began running. Examples include:

date of default
date of acceleration (if applicable)
date of a final demand (if applicable)
date tied to foreclosure/deficiency timing (if supported as the accrual trigger for your theory)

The calculator then applies:

SOL length: 4 years (per Wyo. Stat. § 1-3-105(a)(iv)(C))
End date: start date + 4 years (subject to the tool’s date-handling method)

How outputs change when the start date changes

The start date is the biggest driver of the output. If you move the start date later, the filing deadline moves later as well.

Start date you input	Approx. 4-year SOL deadline	Practical meaning
2019-06-01	2023-06-01	Later start date → later deadline
2020-01-15	2024-01-15	Different trigger choice shifts the clock
2021-09-30	2025-09-30	Foreclosure-related timing may be argued as accrual

Quick checklist before you run

Pitfall to watch: Don’t assume a foreclosure sale date is automatically the SOL trigger. Mortgage-related claims can depend on acceleration language, notice/demand requirements, and when the alleged cause of action accrued.
