How long do I have to appeal a benefits denial?

The denial letter states the window, and internal appeal windows commonly run longer than insurance-style deadlines. Write the date from the letter itself and confirm it in writing; do not quote a generic deadline in your appeal.

Can I sue after an ERISA appeal is denied?

Internal exhaustion is usually required first, and court deadlines vary by benefit type and plan language. Confirm the applicable window with counsel after a final denial, and keep the administrative file you built during the appeal.

What documents should I request from the plan?

The plan document, the summary description, the amendment history in force during your claim, the records the denial relied on, and the reviewer’s identity. Send the request in writing and keep the answer with your appeal.

Can I be fired for filing a benefit claim?

Retaliation for claiming benefits is prohibited, so document the sequence: the claim date, the denial, and any schedule, assignment, or pay change afterward. A dated record is what turns a suspicion into a claim.

ERISA Benefit Disputes: Appeals & Deadlines

ERISA covers most employer benefits: the appeal process runs inside the plan, with a 180-day window, mandatory record production, and litigation after denial. The plan document is the contract — get it in writing.

The Appeal Process

Denial letter: the plan must state the reason and the record used; request the full plan file, the vesting schedule, and the forfeiture language (see the vesting audit guide).
180-day appeal: write the appeal with dates, statements, and the separation letter; the appeal record becomes the litigation file.
Deadlines: ERISA claims have court windows (varies by benefit type); wage and equity claims run in parallel (see the wage claim guide and the 409A guide).

Retaliation for claims is barred; the retaliation record is in the whistleblower guide. The comp archive is in the records guide, and the 401(k) loan trap in the loan guide.

Constructive Discharge — what it means and what to do

Build the claim file before you write the appeal

An ERISA benefit appeal is won on the record the plan already made, so get that record first. You are entitled to the plan documents and to the reasons and documents the denial relied on. Ask in writing, and calendar the appeal deadline the denial letter states.

Request the full plan document and any summary plan description, plus the amendment history if your claim turns on an older version.
Ask which records were considered in the denial, and request copies: medical certifications, payroll dates, vesting records, and the administrator’s notes.
Confirm the appeal window from the denial letter itself, and write the date down. Confirm the window in the letter before you rely on it.
Identify the decision maker. Ask who the plan administrator is, who reviews appeals, and whether a fiduciary with a conflict decided your claim.
Ask what a full and fair review requires so your appeal answers the actual reasons, not your grievances.

Retirement claims often hinge on vesting and service credit; see the 401(k) vesting entry and the cliff entry. Loan offsets have their own clock: read the loan-offset entry before you sign a payout election.

Write the appeal so it becomes the litigation file

Write the appeal as a record, because a later court usually reviews the administrative file, not new argument. Structure it in five parts:

The decision: denial date, claim number, benefit type, and the stated reason quoted exactly.
The facts: dates, employment status, certification dates, and the plan language that supports your position, quoted section by section.
The documents: attach what the plan did not include, and list each attachment with a date.
The ask: state the remedy you want, in dollars or weeks, and ask for the reviewer’s name.
The preservation line: request the complete claim file and any additional records relied on, and ask for the review timeline in writing.

Send it certified or through the portal with a screenshot, and keep your own dated copy. The Department of Labor’s benefits agency oversees plan compliance, so an agency complaint is a separate track from the plan appeal; file it if the plan ignores document requests. For health coverage continuation questions, the state continuation entry explains when state law, not COBRA, controls, and the COBRA election letter documents your election inside the window.

Deadlines, parallel claims, and retaliation

Benefit disputes rarely travel alone, and each track has its own clock:

Court deadlines after a final denial vary by benefit type and by plan language; confirm the window with counsel rather than assuming a fixed number.
Wage claims run in parallel at the state labor agency, and unpaid benefits can be a wage question depending on how they were promised.
Disability decisions interact with Social Security determinations; the SGA entry explains why earnings and work weeks get read together.
Retaliation for claiming benefits is barred, so keep a dated log of every request, denial, and schedule change after you claim.
Equity and 401(k) papers can depend on the same separation date, so align the dates in your appeals.

Keep one timeline for all tracks in the application tracker: denial date, appeal date, decision date, and each parallel filing. A dispute decided on dates is decided by whoever kept them straight.

Benefit type	What the plan must provide	Common denial reason
Health or disability	Plan documents and the records relied on	Missing certification or a definition of disability read narrowly
Retirement or 401(k)	Vesting schedule and service-credit rules	Break in service or a forfeiture the plan does not state clearly
Life or disability insurance	Policy terms and election forms	Late enrollment or a coverage change at separation

The claim review, the appeal window, and the fiduciary duties are federal ERISA rules, and continuation length for small plans is a state rule graded in this build. Confirm the appeal window in the plan document, confirm the continuation length with the state agency named on the state rule pages, and keep the denial letter, the medical records, and the plan language in one dated file so the 180-day clock has a source. Write the appeal with the severance negotiation generator and keep the denial letter in the same file as the plan language.
